116-397: According to research conducted by Microsoft, Alureon was the second most active botnet in the second quarter of 2010. The Alureon bootkit was first identified around 2007. Personal computers are usually infected when users manually download and install Trojan software. Alureon is known to have been bundled with the rogue security software , "Security Essentials 2010" . When the dropper

232-585: A communist-led revolution in Afghanistan, Soviet forces invaded the country, ultimately starting the Soviet–Afghan War . In May 1988, the Soviets started to withdraw from Afghanistan , due to international opposition, persistent anti-Soviet guerrilla warfare, and a lack of support by Soviet citizens. From 1985 onwards, the last Soviet leader Mikhail Gorbachev , who sought to enact liberal reforms in

348-460: A covert channel to the client on the victim's machine (zombie computer). IRC is a historically favored means of C&C because of its communication protocol . A bot herder creates an IRC channel for infected clients to join. Messages sent to the channel are broadcast to all channel members. The bot herder may set the channel's topic to command the botnet. For example, the message :herder!herder@example.com TOPIC #channel DDoS www.victim.com from

464-403: A drive-by download , exploiting web browser vulnerabilities , or by tricking the user into running a Trojan horse program, which may come from an email attachment. This malware will typically install modules that allow the computer to be commanded and controlled by the botnet's operator. After the software is downloaded, it will call home (send a reconnection packet ) to the host computer. When

580-536: A subdomain towards an IRC server that harbors the bots. While these free DNS services do not themselves host attacks, they provide reference points (often hard-coded into the botnet executable). Removing such services can cripple an entire botnet. Calling back to popular sites such as GitHub , Twitter , Reddit , Instagram , the XMPP open source instant message protocol and Tor hidden services are popular ways of avoiding egress filtering to communicate with

696-653: A troika was designated to take charge. Eventually Joseph Stalin , the General Secretary of the Communist Party , managed to suppress all opposition factions and consolidate power in his hands to become the country's dictator by the 1930s. Leon Trotsky , the main proponent of world revolution , was exiled from the Soviet Union in 1929, and Stalin's idea of Socialism in One Country became

812-490: A C&C server. This example illustrates how a botnet is created and used for malicious gain. Newer bots can automatically scan their environment and propagate themselves using vulnerabilities and weak passwords. Generally, the more vulnerabilities a bot can scan and propagate through, the more valuable it becomes to a botnet controller community. Computers can be co-opted into a botnet when they execute malicious software. This can be accomplished by luring users into making

928-611: A Varangian from the Rus' people , named Rurik , was elected ruler of Novgorod in 862. In 882, his successor Oleg ventured south and conquered Kiev , which had been previously paying tribute to the Khazars . Rurik's son Igor and Igor's son Sviatoslav subsequently subdued all local East Slavic tribes to Kievan rule, destroyed the Khazar Khaganate, and launched several military expeditions to Byzantium and Persia . In

1044-521: A botnet can consist of several servers or channels. If one of the servers or channels becomes disabled, the botnet simply switches to another. It is still possible to detect and disrupt additional botnet servers or channels by sniffing IRC traffic. A botnet adversary can even potentially gain knowledge of the control scheme and imitate the bot herder by issuing commands correctly. Since most botnets using IRC networks and domains can be taken down with time, hackers have moved to P2P botnets with C&C to make

1160-554: A botnet is able to direct the activities of these compromised computers through communication channels formed by standards-based network protocols , such as IRC and Hypertext Transfer Protocol (HTTP). Botnets are increasingly rented out by cyber criminals as commodities for a variety of purposes, including as booter/stresser services. Botnet architecture has evolved over time in an effort to evade detection and disruption. Traditionally, bot programs are constructed as clients which communicate via existing servers. This allows

1276-510: A crisis. By 1991, economic and political turmoil began to boil over as the Baltic states chose to secede from the Soviet Union. On 17 March, a referendum was held, in which the vast majority of participating citizens voted in favour of changing the Soviet Union into a renewed federation . In June 1991, Boris Yeltsin became the first directly elected President in Russian history when he

1392-664: A global superpower. After World War II, according to the Potsdam Conference , the Red Army occupied parts of Eastern and Central Europe, including East Germany and the eastern regions of Austria . Dependent communist governments were installed in the Eastern Bloc satellite states. After becoming the world's second nuclear power , the Soviet Union established the Warsaw Pact alliance, and entered into

1508-800: A large confederacy, which was subsequently taken over by the Cumans and the Kipchaks . The ancestors of Russians are among the Slavic tribes that separated from the Proto-Indo-Europeans, who appeared in the northeastern part of Europe c.  1500  years ago. The East Slavs gradually settled western Russia (approximately between modern Moscow and Saint-Petersburg ) in two waves: one moving from Kiev towards present-day Suzdal and Murom and another from Polotsk towards Novgorod and Rostov . Prior to Slavic migration, that territory

1624-584: A large ephemeral botnet to attack large targets such as GitHub in 2015. The botnet controller community constantly competes over who has the most bots, the highest overall bandwidth, and the most "high-quality" infected machines, like university, corporate, and even government machines. While botnets are often named after the malware that created them, multiple botnets typically use the same malware but are operated by different entities. Botnets can be used for many electronic scams. These botnets can be used to distribute malware such as viruses to take control of

1740-409: A predetermined location and await incoming commands from the server. The bot herder sends commands to the server, which relays them to the clients. Clients execute the commands and report their results back to the bot herder. In the case of IRC botnets , infected clients connect to an infected IRC server and join a channel pre-designated for C&C by the bot herder. The bot herder sends commands to

1856-600: A regular users computer/software By taking control of someone's personal computer they have unlimited access to their personal information, including passwords and login information to accounts. This is called phishing . Phishing is the acquiring of login information to the "victim's" accounts with a link the "victim" clicks on that is sent through an email or text. A survey by Verizon found that around two-thirds of electronic "espionage" cases come from phishing. The geographic dispersal of botnets means that each recruit must be individually identified/corralled/repaired and limits

1972-633: A secret protocol within the Molotov–Ribbentrop Pact with Nazi Germany . The Soviet Union later invaded Finland , and occupied and annexed the Baltic states , as well as parts of Romania . On 22 June 1941, Germany invaded the Soviet Union , opening the Eastern Front , the largest theater of World War II. Eventually, some 5 million Red Army troops were captured by the Nazis;

2088-836: A simple C&C botnet protocol in which bots connect to the main command server to host the botnet. Bots are added to the botnet by using a scanning script , which runs on an external server and scans IP ranges for telnet and SSH server default logins. Once a login is found, the scanning server can infect it through SSH with malware, which pings the control server. IRC networks use simple, low bandwidth communication methods, making them widely used to host botnets. They tend to be relatively simple in construction and have been used with moderate success for coordinating DDoS attacks and spam campaigns while being able to continually switch channels to avoid being taken down. However, in some cases, merely blocking of certain keywords has proven effective in stopping IRC-based botnets. The RFC 1459 ( IRC ) standard

2204-726: A slightly modified Simple Mail Transfer Protocol (SMTP) implementation for testing spam capability. Bringing down the Mega-D 's SMTP server disables the entire pool of bots that rely upon the same SMTP server. In computer science , a zombie computer is a computer connected to the Internet that has been compromised by a hacker , computer virus or trojan horse and can be used to perform malicious tasks under remote direction. Botnets of zombie computers are often used to spread e-mail spam and launch denial-of-service attacks (DDoS). Most owners of zombie computers are unaware that their system

2320-517: A struggle for global dominance, known as the Cold War , with the rivalling United States and NATO . After Stalin's death in 1953 and a short period of collective rule , the new leader Nikita Khrushchev denounced Stalin and launched the policy of de-Stalinization , releasing many political prisoners from the Gulag labour camps. The general easement of repressive policies became known later as

2436-401: A very large network, allowing them to watch how botnets work and experiment with ways to stop them. Detecting automated bot becomes more difficult as newer and more sophisticated generations of bots get launched by attackers. For example, an automated attack can deploy a large bot army and apply brute-force methods with highly accurate username and password lists to hack into accounts. The idea

2552-582: Is Moscow . Saint Petersburg is Russia's second-largest city and its cultural capital . The East Slavs emerged as a recognised group in Europe between the 3rd and 8th centuries CE. The first East Slavic state, Kievan Rus' , arose in the 9th century, and in 988, it adopted Orthodox Christianity from the Byzantine Empire . Kievan Rus' ultimately disintegrated; the Grand Duchy of Moscow led

2668-417: Is a group of Internet -connected devices, each of which runs one or more bots . Botnets can be used to perform distributed denial-of-service (DDoS) attacks, steal data, send spam , and allow the attacker to access the device and its connection. The owner can control the botnet using command and control (C&C) software. The word "botnet" is a portmanteau of the words " robot " and " network ". The term

2784-472: Is being used in this way. Because the owner tends to be unaware, these computers are metaphorically compared to zombies . A coordinated DDoS attack by multiple botnet machines also resembles a zombie horde attack. The process of stealing computing resources as a result of a system being joined to a "botnet" is sometimes referred to as "scrumping". Global law enforcement agencies, with the DOJ and FBI, dismantled

2900-465: Is executed, it first hijacks the print spooler service (spoolsv.exe) to update the master boot record and execute a modified bootstrap routine. Then it infects low-level system drivers such as those responsible for PATA operations (atapi.sys) to install its rootkit . Once installed, Alureon manipulates the Windows Registry to block access to Windows Task Manager , Windows Update , and

3016-518: Is one of the earliest types of C&C. A zombie computer accesses a specially-designed webpage or domain(s) which serves the list of controlling commands. The advantages of using web pages or domains as C&C is that a large botnet can be effectively controlled and maintained with very simple code that can be readily updated. Disadvantages of using this method are that it uses a considerable amount of bandwidth at large scale, and domains can be quickly seized by government agencies with little effort. If

3132-595: Is popular with botnets. The first known popular botnet controller script, "MaXiTE Bot" was using IRC XDCC protocol for private control commands. One problem with using IRC is that each bot client must know the IRC server, port, and channel to be of any use to the botnet. Anti-malware organizations can detect and shut down these servers and channels, effectively halting the botnet attack. If this happens, clients are still infected, but they typically lie dormant since they have no way of receiving instructions. To mitigate this problem,

3248-441: Is to overwhelm sites with tens of thousands of requests from different IPs all over the world, but with each bot only submitting a single request every 10 minutes or so, which can result in more than 5 million attempts per day. In these cases, many tools try to leverage volumetric detection, but automated bot attacks now have ways of circumventing triggers of volumetric detection. One of the techniques for detecting these bot attacks

3364-434: Is usually used with a negative or malicious connotation. A botnet is a logical collection of Internet -connected devices, such as computers, smartphones or Internet of things (IoT) devices whose security have been breached and control ceded to a third party. Each compromised device, known as a "bot," is created when a device is penetrated by software from a malware (malicious software) distribution. The controller of

3480-474: Is what's known as "signature-based systems" in which the software will attempt to detect patterns in the request packet. However, attacks are constantly evolving, so this may not be a viable option when patterns cannot be discerned from thousands of requests. There is also the behavioral approach to thwarting bots, which ultimately tries to distinguish bots from humans. By identifying non-human behavior and recognizing known bot behavior, this process can be applied at

3596-554: The Battle of Kursk in the summer of 1943. Another German failure was the Siege of Leningrad , in which the city was fully blockaded on land between 1941 and 1944 by German and Finnish forces, and suffered starvation and more than a million deaths, but never surrendered. Soviet forces steamrolled through Eastern and Central Europe in 1944–1945 and captured Berlin in May 1945. In August 1945,

3712-765: The Brusilov Offensive of the Imperial Russian Army almost completely destroyed the Austro-Hungarian Army . However, the already-existing public distrust of the regime was deepened by the rising costs of war, high casualties , and rumors of corruption and treason. All this formed the climate for the Russian Revolution of 1917, carried out in two major acts. In early 1917, Nicholas II was forced to abdicate ; he and his family were imprisoned and later executed during

3828-475: The Congress of Vienna , which defined the map of post-Napoleonic Europe. The officers who pursued Napoleon into Western Europe brought ideas of liberalism back to Russia, and attempted to curtail the tsar's powers during the abortive Decembrist revolt of 1825. At the end of the conservative reign of Nicholas I (1825–1855), a zenith period of Russia's power and influence in Europe, was disrupted by defeat in

3944-693: The Crimean War . Nicholas's successor Alexander II (1855–1881) enacted significant changes throughout the country, including the emancipation reform of 1861 . These reforms spurred industrialisation, and modernised the Imperial Russian Army, which liberated much of the Balkans from Ottoman rule in the aftermath of the 1877–1878 Russo-Turkish War . During most of the 19th and early 20th century, Russia and Britain colluded over Afghanistan and its neighbouring territories in Central and South Asia;

4060-534: The Eastern Front . With the onset of the Cold War , it competed with the United States for ideological dominance and international influence . The Soviet era of the 20th century saw some of the most significant Russian technological achievements , including the first human-made satellite and the first human expedition into outer space . In 1991, the Russian SFSR emerged from the dissolution of

4176-614: The Great Northern War (1700–1721), securing Russia's access to the sea and sea trade. In 1703, on the Baltic Sea, Peter founded Saint Petersburg as Russia's new capital. Throughout his rule, sweeping reforms were made , which brought significant Western European cultural influences to Russia. He was succeeded by Catherine I (1725–1727), followed by Peter II (1727–1730), and Anna . The reign of Peter I's daughter Elizabeth in 1741–1762 saw Russia's participation in

Flint tools, some 1.5 million years old, have been discovered in the North Caucasus . Radiocarbon dated specimens from Denisova Cave in the Altai Mountains estimate the oldest Denisovan specimen lived 195–122,700 years ago. Fossils of Denny , an archaic human hybrid that

4524-568: The Rurik dynasty that ruled Kievan Rus' collectively. Kiev's dominance waned, to the benefit of Vladimir-Suzdal in the north-east, the Novgorod Republic in the north, and Galicia-Volhynia in the south-west. By the 12th century, Kiev lost its pre-eminence and Kievan Rus' had fragmented into different principalities. Prince Andrey Bogolyubsky sacked Kiev in 1169 and made Vladimir his base, leading to political power being shifted to

4640-843: The Russian Civil War . The monarchy was replaced by a shaky coalition of political parties that declared itself the Provisional Government , and proclaimed the Russian Republic . On 19 January [ O.S. 6 January], 1918, the Russian Constituent Assembly declared Russia a democratic federal republic (thus ratifying the Provisional Government's decision). The next day the Constituent Assembly

Following the Russian Civil War , the Russian SFSR established the Soviet Union with three other Soviet republics , within which it was the largest and principal constituent. At the expense of millions of lives , the Soviet Union underwent rapid industrialisation in the 1930s and later played a decisive role for the Allies in World War II by leading large-scale efforts on

4988-632: The Seven Years' War (1756–1763). During the conflict, Russian troops overran East Prussia , reaching Berlin. However, upon Elizabeth's death, all these conquests were returned to the Kingdom of Prussia by pro-Prussian Peter III of Russia . Catherine II ("the Great"), who ruled in 1762–1796, presided over the Russian Age of Enlightenment . She extended Russian political control over

5104-852: The Siberian River Routes , and by the mid-17th century, there were Russian settlements in eastern Siberia, on the Chukchi Peninsula , along the Amur River , and on the coast of the Pacific Ocean. In 1648, Semyon Dezhnyov became the first European to navigate through the Bering Strait . Under Peter the Great , Russia was proclaimed an empire in 1721, and established itself as one of the European great powers. Ruling from 1682 to 1725, Peter defeated Sweden in

5220-472: The Soviet Union , by joining the Russian SFSR into a single state with the Byelorussian , Transcaucasian , and Ukrainian republics. Eventually internal border changes and annexations during World War II created a union of 15 republics ; the largest in size and population being the Russian SFSR, which dominated the union politically, culturally, and economically. Following Lenin's death in 1924,

Many recent botnets now rely on existing peer-to-peer networks to communicate. These P2P bot programs perform the same actions as the client–server model, but they do not require a central server to communicate. The first botnets on the Internet used a client–server model to accomplish their tasks. Typically, these botnets operate through Internet Relay Chat networks, domains , or websites . Infected clients access

Internationally, Russia ranks very low in measurements of democracy , human rights and freedom of the press ; the country also has high levels of perceived corruption . As of 2024, Russia has a high-income economy which ranks eleventh in

5684-497: The master boot record , which made it particularly resistant on all systems to detection and removal by anti-virus software. TDL-4 is sometimes used synonymously with Alureon and is also the name of the rootkit that runs the botnet. It first appeared in 2008 as TDL-1 being detected by Kaspersky Lab in April 2008. Later version two appeared known as TDL-2 in early 2009. Some time after TDL-2 became known, emerged version three which

5800-666: The 10th to 11th centuries, Kievan Rus' became one of the largest and most prosperous states in Europe. The reigns of Vladimir the Great (980–1015) and his son Yaroslav the Wise (1019–1054) constitute the Golden Age of Kiev, which saw the acceptance of Orthodox Christianity from Byzantium , and the creation of the first East Slavic written legal code , the Russkaya Pravda . The age of feudalism and decentralisation had come, marked by constant in-fighting between members of

Since the turn of the century, Russia's political system has been dominated by Vladimir Putin , under whom the country has experienced democratic backsliding and become an authoritarian dictatorship . Russia has been militarily involved in a number of conflicts in former Soviet states and other countries , including its war with Georgia in 2008 and its war with Ukraine since 2014, which has involved

7308-408: The Soviet Union led Russia into a deep and prolonged depression. During and after the disintegration of the Soviet Union, wide-ranging reforms including privatisation and market and trade liberalisation were undertaken, including radical changes along the lines of " shock therapy ". The privatisation largely shifted control of enterprises from state agencies to individuals with inside connections in

7424-523: The Soviet Union. The transitional disorganisation of the country's agriculture, combined with the harsh state policies and a drought, led to the Soviet famine of 1932–1933 ; which killed 5.7 to 8.7 million, 3.3 million of them in the Russian SFSR. The Soviet Union, ultimately, made the costly transformation from a largely agrarian economy to a major industrial powerhouse within a short span of time. The Soviet Union entered World War II on 17 September 1939 with its invasion of Poland , in accordance with

Early Indo-European migrations from the Pontic–Caspian steppe of Ukraine and Russia spread Yamnaya ancestry and Indo-European languages across large parts of Eurasia. Nomadic pastoralism developed in the Pontic–Caspian steppe beginning in the Chalcolithic . Remnants of these steppe civilizations were discovered in places such as Ipatovo , Sintashta , Arkaim , and Pazyryk , which bear

8004-725: The benefits of filtering . Computer security experts have succeeded in destroying or subverting malware command and control networks, by, among other means, seizing servers or getting them cut off from the Internet, denying access to domains that were due to be used by malware to contact its C&C infrastructure, and, in some cases, breaking into the C&C network itself. In response to this, C&C operators have resorted to using techniques such as overlaying their C&C networks on other existing benign infrastructure such as IRC or Tor , using peer-to-peer networking systems that are not dependent on any fixed servers, and using public key encryption to defeat attempts to break into or spoof

Rather than communicate with a centralized server, P2P bots perform as both a command distribution server and a client which receives commands. This avoids having any single point of failure, which is an issue for centralized botnets. In order to find other infected machines, P2P bots discreetly probe random IP addresses until they identify another infected machine. The contacted bot replies with information such as its software version and list of known bots. If one of

8468-413: The bots' version is lower than the other, they will initiate a file transfer to update. This way, each bot grows its list of infected machines and updates itself by periodically communicating to all known bots. A botnet's originator (known as a " bot herder " or "bot master") controls the botnet remotely. This is known as the command-and-control (C&C). The program for the operation must communicate via

8584-591: The capital Moscow. In 1612, the Poles were forced to retreat by the Russian volunteer corps, led by merchant Kuzma Minin and prince Dmitry Pozharsky . The Romanov dynasty acceded to the throne in 1613 by the decision of the Zemsky Sobor, and the country started its gradual recovery from the crisis. Russia continued its territorial growth through the 17th century, which was the age of the Cossacks . In 1654,

8700-403: The channel via the IRC server. Each client retrieves the commands and executes them. Clients send messages back to the IRC channel with the results of their actions. In response to efforts to detect and decapitate IRC botnets, bot herders have begun deploying malware on peer-to-peer networks. These bots may use digital signatures so that only someone with access to the private key can control

8816-545: The control of the Golden Horde and consolidated the whole of northern Rus' under Moscow's dominion, and was the first Russian ruler to take the title "Grand Duke of all Rus'". After the fall of Constantinople in 1453, Moscow claimed succession to the legacy of the Eastern Roman Empire . Ivan III married Sophia Palaiologina , the niece of the last Byzantine emperor Constantine XI , and made

8932-450: The crucial Battle of Molodi . The death of Ivan's sons marked the end of the ancient Rurik dynasty in 1598, and in combination with the disastrous famine of 1601–1603 , led to a civil war, the rule of pretenders, and foreign intervention during the Time of Troubles in the early 17th century. The Polish–Lithuanian Commonwealth , taking advantage, occupied parts of Russia, extending into

9048-473: The desktop. It also attempts to disable anti-virus software. Alureon has also been known to redirect search engines to commit click fraud . Google has taken steps to mitigate this for their users by scanning for malicious activity and warning users in the case of a positive detection. The malware drew considerable public attention when a software bug in its code caused some 32-bit Windows systems to crash upon installation of security update MS10-015. The malware

9164-507: The domains controlling the botnets are not seized, they are also easy targets to compromise with denial-of-service attacks . Fast-flux DNS can be used to make it difficult to track down the control servers, which may change from day to day. Control servers may also hop from DNS domain to DNS domain, with domain generation algorithms being used to create new DNS names for controller servers. Some botnets use free DNS hosting services such as DynDns.org , No-IP.com , and Afraid.org to point

9280-575: The earliest known traces of horses in warfare . The genetic makeup of speakers of the Uralic language family in northern Europe was shaped by migration from Siberia that began at least 3,500 years ago. In the 3rd to 4th centuries CE, the Gothic kingdom of Oium existed in southern Russia, which was later overrun by Huns . Between the 3rd and 6th centuries CE, the Bosporan Kingdom , which

The French invasion of Russia at the height of Napoleon's power in 1812 reached Moscow, but eventually failed as

9512-564: The first Russian feudal representative body (the Zemsky Sobor ), revamped the military, curbed the influence of the clergy, and reorganised local government. During his long reign, Ivan nearly doubled the already large Russian territory by annexing the three Tatar khanates: Kazan and Astrakhan along the Volga , and the Khanate of Sibir in southwestern Siberia. Ultimately, by the end of

9628-586: The first half of the 19th century, Russia also conquered the Caucasus . Catherine's successor, her son Paul , was unstable and focused predominantly on domestic issues . Following his short reign, Catherine's strategy was continued with Alexander I's (1801–1825) wresting of Finland from the weakened Sweden in 1809, and of Bessarabia from the Ottomans in 1812. In North America, the Russians became

9744-485: The government, which led to the rise of Russian oligarchs . Many of the newly rich moved billions in cash and assets outside of the country in an enormous capital flight . The depression of the economy led to the collapse of social services—the birth rate plummeted while the death rate skyrocketed, and millions plunged into poverty; while extreme corruption, as well as criminal gangs and organised crime rose significantly. In late 1993, tensions between Yeltsin and

9860-549: The internationally unrecognised annexations of Ukrainian territory including Crimea in 2014 and four other regions in 2022 during an ongoing invasion . Russia is a permanent member of the United Nations Security Council ; a member state of the G20 , SCO , BRICS , APEC , OSCE , and WTO ; and the leading member state of post-Soviet organisations such as CIS , CSTO , and EAEU/EEU . It possesses

9976-535: The latter deliberately starved to death or otherwise killed 3.3 million Soviet POWs , and a vast number of civilians, as the " Hunger Plan " sought to fulfil Generalplan Ost . Although the Wehrmacht had considerable early success, their attack was halted in the Battle of Moscow . Subsequently, the Germans were dealt major defeats first at the Battle of Stalingrad in the winter of 1942–1943, and then in

10092-559: The malware will attempt to prevent security software from updating. The "FixMbr" command of the Windows Recovery Console and manual replacement of "atapi.sys" could possibly be required to disable the rootkit functionality before anti-virus tools are able to find and clean an infection. Various companies have created standalone tools which attempt to remove Alureon. Two popular tools are Microsoft Windows Defender Offline and Kaspersky TDSSKiller . On November 9, 2011,

10208-686: The meantime, both the Bolsheviks and White movement carried out campaigns of deportations and executions against each other, known respectively as the Red Terror and White Terror . By the end of the violent civil war, Russia's economy and infrastructure were heavily damaged, and as many as 10 million perished during the war, mostly civilians. Millions became White émigrés , and the Russian famine of 1921–1922 claimed up to five million victims. On 30 December 1922, Lenin and his aides formed

10324-411: The methods fairly and find ways to make them better. The first botnet was first acknowledged and exposed by EarthLink during a lawsuit with notorious spammer Khan C. Smith in 2001. The botnet was constructed for the purpose of bulk spam, and accounted for nearly 25% of all spam at the time. Around 2006, to thwart detection, some botnets were scaling back in size. Russia Russia , or

10440-609: The more recently coined noun россиянин , rossiianyn , "Russian" in the sense of citizen of the Russian state. According to the Primary Chronicle , the word Rus' is derived from the Rus' people , who were a Swedish tribe, and where the three original members of the Rurikid dynasty came from. The Finnish word for Swedes, ruotsi , has the same origin. Later archeological studies mostly confirmed this theory. The first human settlement on Russia dates back to

10556-542: The name Rus ' , Росия ( Rosiya ), was borrowed from the Greek term and first attested in 1387. The name Rossiia appeared in Russian sources in the late 15th century, but until the end of the 17th century the country was more often referred to by its inhabitants as Rus ' , the Russian land ( Russkaia zemlia ), or the Muscovite state ( Moskovskoe gosudarstvo ), among other variations. In 1721, Peter

10672-433: The network. Norton AntiBot was aimed at consumers, but most target enterprises and/or ISPs. Host-based techniques use heuristics to identify bot behavior that has bypassed conventional anti-virus software . Network-based approaches tend to use the techniques described above; shutting down C&C servers, null-routing DNS entries, or completely shutting down IRC servers. BotHunter is software, developed with support from

10788-641: The north-east. Led by Prince Alexander Nevsky , Novgorodians repelled the invading Swedes in the Battle of the Neva in 1240, as well as the Germanic crusaders in the Battle on the Ice in 1242. Kievan Rus' finally fell to the Mongol invasion of 1237–1240, which resulted in the sacking of Kiev and other cities, as well as the death of a major part of the population. The invaders, later known as Tatars , formed

10904-620: The obstinate resistance in combination with the bitterly cold Russian winter led to a disastrous defeat of invaders, in which the pan-European Grande Armée faced utter destruction. Led by Mikhail Kutuzov and Michael Andreas Barclay de Tolly , the Imperial Russian Army ousted Napoleon and drove throughout Europe in the War of the Sixth Coalition , ultimately entering Paris. Alexander I controlled Russia's delegation at

11020-654: The official line. The continued internal struggle in the Bolshevik party culminated in the Great Purge . Under Stalin's leadership, the government launched a command economy , industrialisation of the largely rural country , and collectivisation of its agriculture . During this period of rapid economic and social change, millions of people were sent to penal labour camps , including many political convicts for their suspected or real opposition to Stalin's rule; and millions were deported and exiled to remote areas of

11136-561: The re-connection is made, depending on how it is written, a Trojan may then delete itself or may remain present to update and maintain the modules. In some cases, a botnet may be temporarily created by volunteer hacktivists , such as with implementations of the Low Orbit Ion Cannon as used by 4chan members during Project Chanology in 2010. China's Great Cannon of China allows the modification of legitimate web browsing traffic at internet backbones into China to create

11252-589: The rivalry between the two major European empires came to be known as the Great Game . The late 19th century saw the rise of various socialist movements in Russia. Alexander II was assassinated in 1881 by revolutionary terrorists. The reign of his son Alexander III (1881–1894) was less liberal but more peaceful. Under last Russian emperor, Nicholas II (1894–1917), the Revolution of 1905

11368-484: The rootkit is generally able to avoid detection, circumstantial evidence of the infection may be found through examination of network traffic with a packet analyzer or inspection of outbound connections with a tool such as netstat . Although existing security software on a computer will occasionally report the rootkit, it often goes undetected. It may be useful to perform an offline scan of the infected system after booting an alternative operating system, such as WinPE , as

11484-876: The seat of the Metropolitan of the Russian Orthodox Church moved to Moscow in 1325, its influence increased. Moscow's last rival, the Novgorod Republic , prospered as the chief fur trade centre and the easternmost port of the Hanseatic League . Led by Prince Dmitry Donskoy of Moscow, the united army of Russian principalities inflicted a milestone defeat on the Mongol-Tatars in the Battle of Kulikovo in 1380. Moscow gradually absorbed its parent duchy and surrounding principalities, including formerly strong rivals such as Tver and Novgorod . Ivan III ("the Great") threw off

11600-596: The state of the Golden Horde , which ruled over Russia for the next two centuries. Only the Novgorod Republic escaped foreign occupation after it agreed to pay tribute to the Mongols. Galicia-Volhynia would later be absorbed by Lithuania and Poland , while the Novgorod Republic continued to prosper in the north. In the northeast, the Byzantine-Slavic traditions of Kievan Rus' were adapted to form

11716-483: The threats posed by botnets and the public and private efforts to disrupt and dismantle them. The rise in vulnerable IoT devices has led to an increase in IoT-based botnet attacks. To address this, a novel network-based anomaly detection method for IoT called N-BaIoT was introduced. It captures network behavior snapshots and employs deep autoencoders to identify abnormal traffic from compromised IoT devices. The method

11832-523: The time Chechen separatists declared independence in the early 1990s, an intermittent guerrilla war was fought between the rebel groups and Russian forces. Terrorist attacks against civilians were carried out by Chechen separatists, claiming the lives of thousands of Russian civilians. After the dissolution of the Soviet Union, Russia assumed responsibility for settling the latter's external debts. In 1992, most consumer price controls were eliminated, causing extreme inflation and significantly devaluing

11948-544: The unification of Russian lands, leading to the proclamation of the Tsardom of Russia in 1547. By the early 18th century, Russia had vastly expanded through conquest, annexation, and the efforts of Russian explorers , developing into the Russian Empire , which remains the third-largest empire in history . However, with the Russian Revolution in 1917, Russia's monarchic rule was abolished and eventually replaced by

12064-585: The user, browser, and network levels. The most capable method of using software to combat against a virus has been to utilize honeypot software in order to convince the malware that a system is vulnerable. The malicious files are then analyzed using forensic software. On 15 July 2014, the Subcommittee on Crime and Terrorism of the Committee on the Judiciary, United States Senate , held a hearing on

12180-489: The world by nominal GDP and fourth at purchasing power parity , relying on its vast mineral and energy resources ; the world's second-largest for oil production and natural gas production . Russia is home to 32 UNESCO World Heritage Sites . According to the Oxford English Dictionary , the English name Russia first appeared in the 14th century, borrowed from Medieval Latin : Russia , used in

12296-449: Was elected President of the Russian SFSR. In August 1991, a coup d'état attempt by members of Gorbachev's government, directed against Gorbachev and aimed at preserving the Soviet Union, instead led to the end of the Communist Party of the Soviet Union. On 25 December 1991, following the dissolution of the Soviet Union , along with contemporary Russia, fourteen other post-Soviet states emerged. The economic and political collapse of

Ancient North Eurasian populations from Siberia genetically similar to Mal'ta–Buret' culture and Afontova Gora were an important genetic contributor to Ancient Native Americans and Eastern Hunter-Gatherers . The Kurgan hypothesis places

12760-581: Was half Neanderthal and half Denisovan, and lived some 90,000 years ago, was also found within the latter cave. Russia was home to some of the last surviving Neanderthals, from about 45,000 years ago, found in Mezmaiskaya cave . The first trace of an early modern human in Russia dates back to 45,000 years, in Western Siberia . The discovery of high concentration cultural remains of anatomically modern humans , from at least 40,000 years ago,

12876-584: Was populated by Finno-Ugrian peoples. From the 7th century onwards, the incoming East Slavs slowly assimilated the native Finno-Ugrians.

According to the Primary Chronicle ,

12992-424: Was tested by infecting nine IoT devices with Mirai and BASHLITE botnets, showing its ability to accurately and promptly detect attacks originating from compromised IoT devices within a botnet. Additionally, comparing different ways of detecting botnets is really useful for researchers. It helps them see how well each method works compared to others. This kind of comparison is good because it lets researchers evaluate

13108-487: Was the foundation of the United Nations Security Council . During the war, Soviet civilian and military death were about 26–27 million , accounting for about half of all World War II casualties . The Soviet economy and infrastructure suffered massive devastation, which caused the Soviet famine of 1946–1947 . However, at the expense of a large sacrifice, the Soviet Union emerged as

13224-477: Was titled TDL-3. This led eventually to TDL-4. It was often noted by journalists as "indestructible" in 2011, although it is removable with tools such as Kaspersky 's TDSSKiller. It infects the master boot record of the target machine, making it harder to detect and remove. Major advancements include encrypting communications, decentralized controls using the Kad network , as well as deleting other malware . While

13340-695: Was triggered by the humiliating failure of the Russo-Japanese War . The uprising was put down, but the government was forced to concede major reforms ( Russian Constitution of 1906 ), including granting freedoms of speech and assembly , the legalisation of political parties, and the creation of an elected legislative body, the State Duma . In 1914, Russia entered World War I in response to Austria-Hungary 's declaration of war on Russia's ally Serbia , and fought across multiple fronts while isolated from its Triple Entente allies. In 1916,

13456-482: Was using a hard-coded memory address in the kernel that changed after the installation of the hotfix. Microsoft subsequently modified the hotfix to prevent installation if an Alureon infection is present, The malware author(s) also fixed the bug in the code. In November 2010, the press reported that the rootkit had evolved to the point that it was bypassing the mandatory kernel-mode driver signing requirement of 64-bit editions of Windows 7 . It did this by subverting
