The graph shows the population development in the district of Herrenhausen-Stöcken since 1 January 2005. A major attraction is the baroque Herrenhausen Palace and Herrenhausen Gardens , established by the House of Hanover . The palace

176-420: A Trojan , entering a system through, for example, a malicious attachment, embedded link in a phishing email, or a vulnerability in a network service. The program then runs a payload , which locks the system in some fashion, or claims to lock the system but does not (e.g., a scareware program). Payloads may display a fake warning purportedly by an entity such as a law enforcement agency , falsely claiming that

264-635: A ransomware attack, encrypting numerous company devices and servers, prompting the company to immediately shutdown specific IT systems. In 2024, Johnson Controls was honored as a winner in the Business Intelligence Group's (BIG) Artificial Intelligence Excellence Awards program. Johnson Controls' AI-powered OpenBlue Worker Safety digital solution secured a win in the Machine Learning category, while its OpenBlue Central Utility Plant Optimization solution earned recognition as

352-601: A " fetal protection policy ", which denied women the right to work on the battery production line because of the potential harm to a fetus they might conceive. Women were allowed to work on the production line only if they could prove that "... their inability to bear children had been medically documented." In April 1984, the United Automobile Workers sued Johnson Controls on behalf of three employees. These employees were Mary Craig, who had chosen to be sterilized to avoid losing her job, Elsie Nason,

440-577: A 50-year-old divorcee, who had suffered a loss of compensation when she was transferred from a high paying job that exposed her to lead, and Donald Penney, who had been denied a request for a leave of absence for the purpose of lowering his blood lead levels because he intended to become a father. The case was argued before the Supreme Court of the United States on 10 October 1990 and was decided on 20 March 1991. The Court ruled in favor of

528-447: A 6-digit code. While the malware claimed that this call would be free, it was routed through a rogue operator in a country with high international phone rates, who placed the call on hold, causing the user to incur large international long-distance charges. In 2012, Symantec reported spread out of Eastern Europe of ransomware with a lock screen purporting to be law enforcement demanding payment for illegal activity. In February 2013,

616-429: A Trojan known as CryptoLocker , which generated a 2048-bit RSA key pair and uploaded in turn to a command-and-control server, and used to encrypt files using a whitelist of specific file extensions . The malware threatened to delete the private key if a payment of Bitcoin or a pre-paid cash voucher was not made within 3 days of the infection. Due to the extremely large key size it uses, analysts and those affected by

704-576: A class action settlement whereby Tyco agreed to pay $ 2.92 billion (in conjunction with $ 225 million by Pricewaterhouse Coopers, their auditors) to a class of defrauded shareholders represented by Grant & Eisenhofer P.A. , Schiffrin, Barroway, Topaz & Kessler, and Milberg Weiss & Bershad. On 17 January 2014, Kozlowski was granted parole from Lincoln Correctional Facility in New York City. In 2016, Johnson Controls agreed to pay $ 14.4M to settle Foreign Corrupt Practices Act charges with

792-503: A crime as the company's top executive. On 17 June 2005, after a retrial, Kozlowski and Swartz were convicted on all but one of the more than 30 counts against them. The verdicts carry potential jail terms of up to 25 years in state prison. Kozlowski and Swartz were each sentenced to no less than eight years and four months and no more than 25 years in prison. Then in May 2007, New Hampshire Federal District Court Judge Paul Barbadoro approved

880-412: A design failure so severe it was not necessary to pay the extortionist at all. Its payload hid the files on the hard drive and encrypted only their names , and displayed a message claiming that the user's license to use a certain piece of software had expired. The user was asked to pay US$ 189 to "PC Cyborg Corporation" in order to obtain a repair tool even though the decryption key could be extracted from

968-493: A fictitious criminal charge. Fusob requests iTunes gift cards for payment, unlike most cryptocurrency-centric ransomware. In order to infect devices, Fusob masquerades as a pornographic video player. When it is installed, it first checks the device's system language. If the language is Russian or Eastern-European, Fusob remains dormant. Otherwise, it locks the device and demands ransom. About 40% of victims are in Germany, while

1056-552: A finalist in the Intelligent Control category. Sensormatic Solutions, the global retail solutions portfolio of Johnson Controls, clinched victory in the Computer Vision category for its Computer Vision Analytics. In July 2024, Johnson Controls said that it will sell a portfolio of its heating and ventilation units to Germany's Bosch Group for $ 6.7 billion. In 1982, Johnson Controls enacted what it called

1144-953: A form of clickjacking to cause the user to give it "device administrator" privileges to achieve deeper access to the system. Different tactics have been used on iOS devices, such as exploiting iCloud accounts and using the Find My iPhone system to lock access to the device. On iOS 10.3 , Apple patched a bug in the handling of JavaScript pop-up windows in Safari that had been exploited by ransomware websites. It recently has been shown that ransomware may also target ARM architectures like those that can be found in various Internet-of-Things (IoT) devices, such as Industrial IoT edge devices. In August 2019 researchers demonstrated it's possible to infect DSLR cameras with ransomware. Digital cameras often use Picture Transfer Protocol (PTP - standard protocol used to transfer files.) Researchers found that it

1232-544: A new company, Clarios , as of 1 May 2019. The Power Solutions business unit designs and manufactures automotive batteries for passenger cars, heavy and light duty trucks, utility vehicles, motorcycles, golf carts and boats. It supplies more than one third of the world's lead-acid batteries to automakers and aftermarket retailers including Wal-Mart, Sears, Toyota, and BMW. Lead acid battery brands produced under this business unit include Continental, OPTIMA, Heliar, LTH, Delkor and VARTA automotive batteries. This part of

1320-433: A page to scan for malware, this variant was designed to require users to visit a web page and enter a CAPTCHA code before the payload is actually downloaded, preventing such automated processes from being able to scan the payload. Symantec determined that these new variants, which it identified as CryptoLocker.F , were again, unrelated to the original CryptoLocker due to differences in their operation. A notable victim of

1408-590: A patent for the first electric room thermostat. His invention helped launch the building control industry and was the impetus for a new company. Johnson and a group of Milwaukee investors led by William Plankinton incorporated the Johnson Electric Service Company in 1885 to manufacture, install and service automatic temperature regulation systems for buildings. After Johnson died in 1911, the company decided to focus on its temperature control business for non-residential buildings. In 1970,

1496-409: A private individual's photographs and documents) that the ransomware had encrypted. As ransomware matured as a business, organised gangs entered the field, advertising on the dark Web for experts, and outsourcing functions. This led to improvement in the quality of ransomware and its success. Rather than random emails, the gangs stole credentials, found vulnerabilities in target networks, and improved

1584-407: A process known as a tax inversion. This restructuring came at great expense of the workforce which was reduced by 52% between 2016 and 2022. The same occurred after the takeover of York International in 2005, which led to a reduction of 76% of the workforce between 2005 and 2016. Hillary Clinton condemned the company for wanting to escape United States taxes through the merger after having "begged"

1672-471: A ransomware Trojan based on the Stamp.EK exploit kit surfaced; the malware was distributed via sites hosted on the project hosting services SourceForge and GitHub that claimed to offer "fake nude pics" of celebrities. In July 2013, an OS X -specific ransomware Trojan surfaced, which displays a web page that accuses the user of downloading pornography. Unlike its Windows-based counterparts, it does not block

1760-416: A ransomware Trojan known as WinLock. Unlike the previous Gpcode Trojan, WinLock did not use encryption. Instead, WinLock trivially restricted access to the system by displaying pornographic images and asked users to send a premium-rate SMS (costing around US$ 10) to receive a code that could be used to unlock their machines. The scam hit numerous users across Russia and neighbouring countries—reportedly earning

1848-408: A state of emergency and announce that Costa Rica is "at war" with its ransomware hackers. In some infections, there is a two-stage payload, common in many malware systems. The user is tricked into running a script, which downloads the main virus and executes it. In early versions of the dual-payload system, the script was contained in a Microsoft Office document with an attached VBScript macro, or in

1936-448: A warning purportedly from a law enforcement agency claiming that the computer has been used for illegal activities, such as downloading unlicensed software or child pornography . Due to this behaviour, it is commonly referred to as the "Police Trojan". The warning informs the user that to unlock their system, they would have to pay a fine using a voucher from an anonymous prepaid cash service such as Ukash or paysafecard . To increase

2024-574: A windows scripting facility (WSF) file. As detection systems started blocking these first stage payloads, the Microsoft Malware Protection Center identified a trend away toward LNK files with self-contained Microsoft Windows PowerShell scripts. In 2016, PowerShell was found to be involved in nearly 40% of endpoint security incidents. Some ransomware strains have used proxies tied to Tor hidden services to connect to their command and control servers, increasing

2112-480: Is actually intelligence gathering. The first reported death following a ransomware attack was at a German hospital in October 2020. A significant increase in ransomware attacks occurred during the 2020 COVID-19 pandemic . Evidence has demonstrated  that the targeted institutions of these attacks included government, finance, and healthcare. Researchers have contended that several different factors can explain

2200-599: Is an American, Irish-domiciled multinational conglomerate headquartered in Cork , Ireland , that produces fire , HVAC , and security equipment for buildings. As of mid-2019, it employed 105,000 people in around 2,000 locations across six continents. In 2017 it was listed as 389th in the Fortune Global 500 . It became ineligible for the Fortune 500 in subsequent years since it relocated its headquarters outside

2288-470: Is little incentive to encrypt data since it can be easily restored via online synchronization. Mobile ransomware typically targets the Android platform, as it allows applications to be installed from third-party sources. The payload is typically distributed as an APK file installed by an unsuspecting user; it may attempt to display a blocking message over top of all other applications, while another used

2376-419: Is repaired. The most sophisticated payloads encrypt files, with many using strong encryption to encrypt the victim's files in such a way that only the malware author has the needed decryption key. Payment is virtually always the goal, and the victim is coerced into paying for the ransomware to be removed either by supplying a program that can decrypt the files, or by sending an unlock code that undoes

2464-483: The Bitcoin cryptocurrency . In May 2020, vendor Sophos reported that the global average cost to remediate a ransomware attack (considering downtime, people time, device cost, network cost, lost opportunity and ransom paid) was $ 761,106. Ninety-five percent of organizations that paid the ransom had their data restored. The first known malware extortion attack, the "AIDS Trojan" written by Joseph Popp in 1989, had

2552-522: The SEC . According to the SEC, employees of China Marine, a subsidiary of Johnson Controls, employed sham vendors to transfer $ 4.9M worth of bribes to Chinese government-owned shipyards, to win over businesses and enrich themselves. Ransomware Ransomware is a type of malware that permanently blocks access to the victim's personal data unless a "ransom" is paid. While some simple ransomware may lock

2640-613: The Zedo ad network in late-September 2014 that targeted several major websites; the ads redirected to rogue websites that used browser plugin exploits to download the payload. A Barracuda Networks researcher also noted that the payload was signed with a digital signature in an effort to appear trustworthy to security software. CryptoWall 3.0 used a payload written in JavaScript as part of an email attachment, which downloads executables disguised as JPG images. To further evade detection,

2728-484: The 2008–2009 recession, the company's president, Keith Wandell, lobbied Congress for a bailout of the companies that Johnson supplied. The Johnson Controls plant in Lakeshore, Ontario, closed in late March 2010 and the property was sold. In 2013, Stephen Roell retired and Alex Molinaroli took his position as CEO and chairman of the board. On 31 October 2016, the former Johnson Controls Automotive Experience division

2816-529: The August 2014 discovery of a Trojan specifically targeting network-attached storage devices produced by Synology . In January 2015, it was reported that ransomware-styled attacks have occurred against individual websites via hacking, and through ransomware designed to target Linux -based web servers . In 2022, Costa Rica received widespread Conti ransomware attacks affecting government, healthcare and industry. This lead President Rodrigo Chaves to declare

2904-454: The FBI. Globally, according to Statistica , there were about 623 million ransomware attacks in 2021, and 493 million in 2022. The concept of file-encrypting ransomware was invented and implemented by Young and Yung at Columbia University and was presented at the 1996 IEEE Security & Privacy conference. It is called cryptoviral extortion and it was inspired by the fictional facehugger in

2992-562: The Global Workplace Solutions business unit, retaining the name "Global Workplace Solutions". Coleman Heating & Air Conditioning is a major manufacturing brand of HVAC equipment, and was formerly an independent HVAC manufacturing company. The company began as a division of the Coleman Company in 1958 and was acquired by Evcon in 1990, which in turn was acquired by Johnson Controls in 1996. Of

3080-619: The Metropolitan Police clarified that they would never lock a computer in such a way as part of an investigation. In May 2012, Trend Micro threat researchers discovered templates for variations for the United States and Canada , suggesting that its authors may have been planning to target users in North America. By August 2012, a new variant of Reveton began to spread in the United States, claiming to require

3168-751: The North American Market under various brands including York and Coleman. The Norman plant primarily produces rooftop units (RTUs) for commercial use. On 25 January 2016, Johnson Controls announced that it would merge with Tyco International to create Johnson Controls International plc, a company headquartered in Cork, Ireland. The merger was completed in September 2016. Merging with the Irish company allowed Johnson Controls to become an Irish company itself, and enjoy sharply lowered corporate taxes,

3256-698: The Russian hacker Evgeniy Bogachev for his alleged involvement in the botnet. It was estimated that at least US$ 3 million was extorted with the malware before the shutdown. In September 2014, a wave of ransomware Trojans surfaced that first targeted users in Australia , under the names CryptoWall and CryptoLocker (which is, as with CryptoLocker 2.0, unrelated to the original CryptoLocker). The Trojans spread via fraudulent e-mails claiming to be failed parcel delivery notices from Australia Post ; to evade detection by automatic e-mail scanners that follow all links on

3344-625: The Trojan considered CryptoLocker extremely difficult to repair. Even after the deadline passed, the private key could still be obtained using an online tool, but the price would increase to 10 BTC—which cost approximately US$ 2300 as of November 2013. CryptoLocker was isolated by the seizure of the Gameover ZeuS botnet as part of Operation Tovar , as officially announced by the U.S. Department of Justice on 2 June 2014. The Department of Justice also publicly issued an indictment against

3432-580: The Trojans was the Australian Broadcasting Corporation ; live programming on its television news channel ABC News 24 was disrupted for half an hour and shifted to Melbourne studios due to a CryptoWall infection on computers at its Sydney studio. Another Trojan in this wave, TorrentLocker , initially contained a design flaw comparable to CryptoDefense; it used the same keystream for every infected computer, making

3520-647: The U.S. The company was formed via the merger of American company Johnson Controls with Tyco International , announced on 25 January 2016. The merger led to the avoidance of taxation on foreign market operations and a financial windfall for the CEO of Johnson Controls at that time, Alex Molinaroli . In 1883, Warren S. Johnson , a professor at the Whitewater Normal School (now University of Wisconsin–Whitewater) in Whitewater, Wisconsin , received

3608-676: The acquisition of Silent-Aire. (Silent-Aire was a Canadian firm that specialized in data center cooling systems. The deal was structured as follows: Johnson Controls paid $ 630 million upfront, and additional payments were made contingent upon reaching certain milestones, with total price capped at $ 870 million.) In October 2021, it was announced that Johnson Controls had picked Ava Robotics to power its new 'Tyco Security Robot'. This fully autonomous security robot includes sensors, touchscreen and integrates two Tyco Illustra cameras to bring access control, video surveillance and security robotics together. In September 2023, Johnson Controls' experienced

3696-451: The attack itself was a success. Common targets for exfiltration include: Exfiltration attacks are usually targeted, with a curated victim list, and often preliminary surveillance of the victim's systems to find potential data targets and weaknesses. With the increased popularity of ransomware on PC platforms, ransomware targeting mobile operating systems has also proliferated. Typically, mobile ransomware payloads are blockers, as there

3784-467: The attack that is presented here the victim retains access to the information but its disclosure is at the discretion of the computer virus". The attack is rooted in game theory and was originally dubbed "non-zero sum games and survivable malware". The attack can yield monetary gain in cases where the malware acquires access to information that may damage the victim user or organization, e.g., the reputational damage that could result from publishing proof that

3872-420: The board of directors authorized it as compensation. Kozlowski was tried twice. The first attempt was a ruled mistrial when one of the jurors was threatened by the public after being reported to have made an OK sign towards Kozlowski's lawyers. Kozlowski testified on his own behalf during the second trial, stating that his pay package was "confusing" and "almost embarrassingly big," but that he never committed

3960-417: The code of the Trojan. The Trojan was also known as "PC Cyborg". Popp was declared mentally unfit to stand trial for his actions, but he promised to donate the profits from the malware to fund AIDS research. The idea of abusing anonymous cash systems to safely collect ransom from human kidnapping was introduced in 1992 by Sebastiaan von Solms and David Naccache . This electronic money collection method

4048-682: The company also manufactures Lithium-ion cells and complete battery systems to power hybrid and electric vehicles such as the Ford Fusion and Daimler's S-Class 400. Additionally, it manufactures absorbent glass mat (AGM) and enhanced flooded batteries (EFB) batteries to power Start-Stop vehicles such as the Chevy Malibu and Ford Fusion. As of 2012, the business unit operated from 60 locations worldwide. On 13 November 2018 Johnson Controls agrees to sell its Power Solutions Division to Brookfield Business Partners. This business unit

4136-554: The company took over clock manufacturer Standard Electric Time Company . The company was renamed Johnson Controls in 1974. In 1978, Johnson Controls acquired the battery company Globe-Union. That same year, the company divested itself of the Standard Electric Time Company and sold it to Faraday . In 1985, Johnson Controls acquired automotive seating companies Hoover Universal and Ferro Manufacturing. In 1989, Johnson acquired Pan Am World Services. During

4224-426: The data in files but also the file names. Fusob is a major family of mobile ransomware. Between April 2015 and March 2016, about 56 percent of accounted mobile ransomware was Fusob. Like most other pieces of ransomware, it employs scare tactics to extort a hefty sum from the user. The app acts as if it were a notice from the authorities , demanding the victim to pay a fine from $ 100 to $ 200 USD or otherwise face

4312-427: The data publicly if the ransom was not paid; in at least one case they did this. Many other gangs followed; "leak sites" were created on the dark web where stolen data could be accessed. Later attacks focussed on the threat to leak data, without necessarily locking it—this negated the protection afforded victims by robust backup procedures. As of 2023 there is a risk of hostile governments using ransomware to conceal what

4400-465: The difficulty of tracing the exact location of the criminals. Furthermore, dark web vendors have increasingly started to offer the technology as a service , wherein ransomware is sold, ready for deployment on victims' machines, on a subscription basis, similarly to Adobe Creative Cloud or Office 365. Symantec has classified ransomware to be the most dangerous cyber threat. In August 2010, Russian authorities arrested nine individuals connected to

4488-456: The e-money was previously encrypted by the user, it is of no use to the user if it gets encrypted by a cryptovirus". They referred to these attacks as being " cryptoviral extortion", an overt attack that is part of a larger class of attacks in a field called cryptovirology , which encompasses both overt and covert attacks. The cryptoviral extortion protocol was inspired by the parasitic relationship between H. R. Giger's facehugger and its host in

4576-648: The electric thermostat in 1883. As of 2012, the business unit operated from 700 branch offices in more than 150 countries. Johnson Controls was one of the defendants in a multimillion-dollar federal court lawsuit in San Juan, Puerto Rico in a case where 98 people perished and 140 were injured in a fire at the DuPont Plaza Hotel and its casino on New Year's Eve, 31 December 1986. The plaintiffs claimed that Johnson Controls sold and installed an energy management system that failed to give early warning of

4664-462: The encryption trivial to overcome. However, this flaw was later fixed. By late-November 2014, it was estimated that over 9,000 users had been infected by TorrentLocker in Australia alone, trailing only Turkey with 11,700 infections. Another major ransomware Trojan targeting Windows, CryptoWall, first appeared in 2014. One strain of CryptoWall was distributed as part of a malvertising campaign on

4752-603: The energy consumption and operating costs of their buildings. This includes retrofitting existing buildings such as the Empire State Building and working on maximizing efficiency in new construction such as the Burj Khalifa in Dubai. Building Technologies & Solutions is the company's longest-running business unit, dating to 1885 when Johnson founded the Johnson Electric Service Company after patenting

4840-499: The entire computer, but simply exploits the behaviour of the web browser itself to frustrate attempts to close the page through normal means. In July 2013, a 21-year-old man from Virginia, whose computer coincidentally did contain pornographic photographs of underage girls with whom he had conducted sexualized communications, turned himself in to police after receiving and being deceived by FBI MoneyPak Ransomware accusing him of possessing child pornography. An investigation discovered

4928-552: The fatal flaw being that the decryption key could be extracted from the Trojan, and implemented an experimental proof-of-concept cryptovirus on a Macintosh SE/30 that used RSA and the Tiny Encryption Algorithm (TEA) to hybrid encrypt the victim's data. Since public key cryptography is used, the virus only contains the encryption key. The attacker keeps the corresponding private decryption key private. Young and Yung's original experimental cryptovirus had

5016-409: The fire. After nine months of trial, the company and its energy management system were absolved of blame when the court issued a directed verdict. When the trial was completed the plaintiffs had accumulated approximately $ 220,908,549.00 in damages as a result of various settlements and a jury verdict against some other defendants. This unit was sold to Brookfield Business Partners and re-made into

5104-466: The first documented ransomware known as the AIDS trojan , the use of ransomware scams has grown internationally. There were 181.5 million ransomware attacks in the first six months of 2018. This record marks a 229% increase over this same time frame in 2017. In June 2014, vendor McAfee released data showing that it had collected more than double the number of ransomware samples that quarter than it had in

5192-518: The first time since 2013, in 2018 there was an observed decrease in ransomware activity with a drop of 20 percent. Before 2017, consumers were the preferred victims, but in 2017 this changed dramatically, it moved to the enterprises. In 2018 this path accelerated with 81 percent infections which represented a 12 percent increase. The common distribution method today is based on email campaigns. In late 2019 ransomware group Maze downloaded companies' sensitive files before locking them, and threatened to leak

5280-502: The government for financial help in 2008. The Johnson deal was termed "outrageous" by Fortune magazine. The firm estimated that it would save about US$ 150 million a year by avoiding American taxes. In 2002, former chairman and chief executive Dennis Kozlowski and former chief financial officer Mark H. Swartz were accused of the theft of more than US$ 150 million from the company. During their trial in March 2004, they contended

5368-499: The group over US$ 16 million. In 2011, a ransomware Trojan surfaced that imitated the Windows Product Activation notice, and informed users that a system's Windows installation had to be re-activated due to "[being a] victim of fraud". An online activation option was offered (like the actual Windows activation process), but was unavailable, requiring the user to call one of six international numbers to input

Reveton initially began spreading in various European countries in early 2012. Variants were localized with templates branded with the logos of different law enforcement organizations based on

5544-541: The increase in attacks during this time. However, a major factor is that remote work , which became the norm for many industries in 2020, led to the surge in attacks because of the lack of security in comparison to traditional work environments. In 2012, a major ransomware Trojan known as Reveton began to spread. Based on the Citadel Trojan (which, itself, is based on the Zeus Trojan), its payload displays

5632-444: The incriminating files, and the man was charged with child sexual abuse and possession of child pornography. The converse of ransomware is a cryptovirology attack invented by Adam L. Young that threatens to publish stolen information from the victim's computer system rather than deny the victim access to it. In a leakware attack, malware exfiltrates sensitive host data either to the attacker or alternatively, to remote instances of

5720-602: The malware creates new instances of explorer.exe and svchost.exe to communicate with its servers. When encrypting files, the malware also deletes volume shadow copies and installs spyware that steals passwords and Bitcoin wallets . The FBI reported in June 2015 that nearly 1,000 victims had contacted the bureau's Internet Crime Complaint Center to report CryptoWall infections, and estimated losses of at least $ 18 million. The most recent version, CryptoWall 4.0, enhanced its code to avoid antivirus detection, and encrypts not only

5808-530: The malware to avoid detection by anti-malware scanners. Ransoms demanded escalated into the much larger sums (millions) that an enterprise would pay to recover its data, rather than what an individual would pay for their documents (hundreds). In 2016, a significant uptick in ransomware attacks on hospitals was noted. According to the 2017 Internet Security Threat Report from Symantec Corp, ransomware affected not only IT systems but also patient care, clinical operations, and billing. Online criminals may be motivated by

5896-403: The malware, and the attacker threatens to publish the victim's data unless a ransom is paid. The attack was presented at West Point in 2003 and was summarized in the book Malicious Cryptography as follows, "The attack differs from the extortion attack in the following way. In the extortion attack, the victim is denied access to its own valuable information and has to pay to get it back, where in

5984-609: The money available and sense of urgency within the healthcare system. Ransomware is growing rapidly across the internet users but also for the IoT environment. The big problem is that millions of dollars are lost by some organizations and industries that have decided to pay, such as the Hollywood Presbyterian Medical Center and the MedStar Health. According to Symantec 2019 ISTR report, for

6072-414: The movie Alien . Examples of extortionate ransomware became prominent in May 2005. By mid-2006, Trojans such as Gpcode , TROJ.RANSOM.A, Archiveus , Krotten, Cryzip, and MayArchive began utilizing more sophisticated RSA encryption schemes, with ever-increasing key-sizes. Gpcode.AG, which was detected in June 2006, was encrypted with a 660-bit RSA public key. In June 2008, a variant known as Gpcode.AK

6160-432: The movie Alien . Cryptoviral extortion is the following three-round protocol carried out between the attacker and the victim. The symmetric key is randomly generated and will not assist other victims. At no point is the attacker's private key exposed to victims and the victim need only send a very small ciphertext (the encrypted symmetric-cipher key) to the attacker. Ransomware attacks are typically carried out using

6248-436: The operators of CryptoLocker had procured about US$ 27 million from infected users. The CryptoLocker technique was widely copied in the months following, including CryptoLocker 2.0 (thought not to be related to CryptoLocker), CryptoDefense (which initially contained a major design flaw that stored the private key on the infected system in a user-retrievable location , due to its use of Windows' built-in encryption APIs), and

6336-545: The payload's changes. While the attacker may simply take the money without returning the victim's files, it is in the attacker's best interest to perform the decryption as agreed, since victims will stop sending payments if it becomes known that they serve no purpose. A key element in making ransomware work for the attacker is a convenient payment system that is hard to trace. A range of such payment methods have been used, including wire transfers , premium-rate text messages , pre-paid voucher services such as paysafecard , and

6424-547: The payment of a $ 200 fine to the FBI using a MoneyPak card.

6600-471: The ransoms, making tracing and prosecuting the perpetrators difficult. Ransomware attacks are typically carried out using a Trojan disguised as a legitimate file that the user is tricked into downloading or opening when it arrives as an email attachment. However, one high-profile example, the WannaCry worm , traveled automatically between computers without user interaction. Starting as early as 1989 with

6688-565: The same quarter the previous year. CryptoLocker was particularly successful, procuring an estimated US$ 3 million before it was taken down by authorities, and CryptoWall was estimated by the US Federal Bureau of Investigation (FBI) to have accrued over US$ 18 million by June 2015. In 2020, the IC3 received 2,474 complaints identified as ransomware with adjusted losses of over $ 29.1 million. The losses could be more than that, according to

6776-462: The system has been used for illegal activities, contains content such as pornography and "pirated" media . Some payloads consist simply of an application designed to lock or restrict the system until payment is made, typically by setting the Windows Shell to itself, or even modifying the master boot record and/or partition table to prevent the operating system from booting until it

6864-474: The system without damaging any files, more advanced malware uses a technique called cryptoviral extortion. It encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them. In a properly implemented cryptoviral extortion attack, recovering the files without the decryption key is an intractable problem, and difficult-to-trace digital currencies such as paysafecard or Bitcoin and other cryptocurrencies are used for

Long before electronic money existed Young and Yung proposed that electronic money could be extorted through encryption as well, stating that "the virus writer can effectively hold all of the money ransom until half of it is given to him. Even if

7216-432: Was also proposed for cryptoviral extortion attacks. In the von Solms-Naccache scenario a newspaper publication was used (since bitcoin ledgers did not exist at the time the paper was written). The notion of using public key cryptography for data kidnapping attacks was introduced in 1996 by Adam L. Young and Moti Yung . Young and Yung critiqued the failed AIDS Information Trojan that relied on symmetric cryptography alone,

7304-446: Was detected. Using a 1024-bit RSA key, it was believed large enough to be computationally infeasible to break without a concerted distributed effort. Encrypting ransomware returned to prominence in late 2013 with the propagation of CryptoLocker —using the Bitcoin digital currency platform to collect ransom money. In December 2013, ZDNet estimated based on Bitcoin transaction information that between 15 October and 18 December,

Johnson Controls Johnson Controls International plc

7480-574: Was possible to exploit vulnerabilities in the protocol to infect target camera(s) with ransomware (or execute any arbitrary code). This attack was presented at the Defcon security conference in Las Vegas as a proof of concept attack (not as actual armed malware). The first attacks were on random users, typically infected through email attachments sent by small groups of criminals, demanding a few hundred dollars in cryptocurrency to unlock files (typically

7568-511: Was sold to them for $ 3.2 billion. At the time of the acquisition, it was the world's largest independent manufacturer of air conditioning, heating, and refrigeration machinery.
