The CryptoLocker ransomware attack was a cyberattack using the CryptoLocker ransomware that occurred from 5 September 2013 to late May 2014. The attack utilized a trojan that targeted computers running on Microsoft Windows , and was believed to have first been posted to the Internet on 5 September 2013. It propagated via infected email attachments, and via an existing Gameover ZeuS botnet . When activated, the malware encrypted certain types of files stored on local and mounted network drives using RSA public-key cryptography , with the private key stored only on the malware's control servers. The malware then displayed a message which offered to decrypt the data if a payment (through either bitcoin or a pre-paid cash voucher) was made by a stated deadline, and it threatened to delete the private key if the deadline passes. If the deadline was not met, the malware offered to decrypt data via an online service provided by the malware's operators, for a significantly higher price in bitcoin. There was no guarantee that payment would release the encrypted content.
87-404: Although CryptoLocker itself was easily removed, the affected files remained encrypted in a way which researchers considered unfeasible to break. Many said that the ransom should not be paid, but did not offer any way to recover files; others said that paying the ransom was the only way to recover files that had not been backed up . Some victims claimed that paying the ransom did not always lead to
174-511: A CAPTCHA code before the payload is actually downloaded. Symantec determined that these new variants, which it identified as "CryptoLocker.F", were not tied to the original. Ransom Ransom is the practice of holding a prisoner or item to extort money or property to secure their release, or the sum of money involved in such a practice. When ransom means "payment", the word comes via Old French rançon from Latin redemptio , 'buying back'; compare " redemption ". Julius Caesar

The FBI is organized into functional branches and the Office of the Director, which contains most administrative offices. An executive assistant director manages each branch. Each branch is then divided into offices and divisions, each headed by an assistant director. The various divisions are further divided into sub-branches, led by deputy assistant directors. Within these sub-branches, there are various sections headed by section chiefs. Section chiefs are ranked analogous to special agents in charge. Four of
435-599: A civil rights leader, surgeon, and wealthy entrepreneur in Mississippi who had criticized FBI inaction in solving recent murders of George W. Lee , Emmett Till , and other blacks in the South. The FBI carried out controversial domestic surveillance in an operation it called the COINTELPRO , from "COunter-INTELligence PROgram". It was to investigate and disrupt the activities of dissident political organizations within
522-621: A dedicated FBI SWAT team dealing primarily with counter-terrorism scenarios. Unlike the special agents serving on local FBI SWAT teams, HRT does not conduct investigations. Instead, HRT focuses solely on additional tactical proficiency and capabilities. Also formed in 1984 was the Computer Analysis and Response Team , or CART. From the end of the 1980s to the early 1990s, the FBI reassigned more than 300 agents from foreign counter-intelligence duties to violent crime, and made violent crime
609-580: A dispute with Richard Jewell , who was a private security guard at the venue, along with some media organizations, in regard to the leaking of his name during the investigation; this had briefly led to his being wrongly suspected of the bombing. After Congress passed the Communications Assistance for Law Enforcement Act (CALEA, 1994), the Health Insurance Portability and Accountability Act (HIPAA, 1996), and
696-580: A few hours after the attack, and over the next several weeks more than 5,500 Issei men were taken into FBI custody. On February 19, 1942, President Franklin Roosevelt issued Executive Order 9066 , authorizing the removal of Japanese Americans from the West Coast. FBI Director Hoover opposed the subsequent mass removal and confinement of Japanese Americans authorized under Executive Order 9066, but Roosevelt prevailed. The vast majority went along with

A ZIP file attached to an email message contains an executable file with the filename and the icon disguised as a PDF file, taking advantage of Windows' default behaviour of hiding the extension from file names to disguise the real .EXE extension. CryptoLocker was also propagated using the Gameover ZeuS trojan and botnet. When first run, the payload installs itself in

On 2 June 2014, the United States Department of Justice officially announced that over the previous weekend, Operation Tovar —a consortium constituting a group of law enforcement agencies (including the FBI and Interpol ), security software vendors, and several universities, had disrupted
957-466: A ploy to convince family members that a person is being held for ransom when that person has actually left of their own volition or was already dead before the note was sent. There were numerous instances in which towns paid to avoid being plundered, an example being Salzburg which, under Paris Lodron , paid a ransom to Bavaria to prevent its being sacked during the Thirty Years' War . As late as

#17327945858421044-543: A report whose conclusions called into question 30 years of FBI testimony. It found the analytic model used by the FBI for interpreting results was deeply flawed, and the conclusion, that bullet fragments could be matched to a box of ammunition, was so overstated that it was misleading under the rules of evidence. One year later, the FBI decided to stop conducting bullet lead analyses. After a 60 Minutes / The Washington Post investigation in November 2007, two years later,
1131-493: A result. In December 2013, ZDNet traced four bitcoin addresses posted by users who had been infected by CryptoLocker, in an attempt to gauge the operators' takings. The four addresses showed movement of 41,928 BTC between 15 October and 18 December — about US$ 27 million at that time. In a survey by researchers at the University of Kent , 41% of those who claimed to be victims said that they had decided to pay
1218-500: A rigged trial. The ransom payment received by Pizarro is recognized as the largest ever paid to a single individual, probably over $ 2 billion in today's economic markets. The abduction of Charley Ross on July 1, 1874, is considered to be the first American kidnapping for ransom. East Germany , which built the Inner German border to stop emigration, practised ransom with people. East German citizens could emigrate through
1305-413: A sample file, and then receive a decryption tool. While security software is designed to detect such threats, it might not detect CryptoLocker at all, or only after encryption is underway or complete, particularly if a new version unknown to the protective software is distributed. If an attack is suspected or detected in its early stages, it takes some time for encryption to take place; immediate removal of
1392-501: A worker to around 11,250 DM for a physician. For a while, payments were made in kind using goods that were in short supply in East Germany, such as oranges, bananas, coffee, and medical drugs. The average prisoner was worth around 4,000 DM worth of goods. A request for ransom may be conveyed to the target of the effort by a ransom note, a written document outlining the demands of the kidnappers. In some instances, however,

In March 1971, the residential office of an FBI agent in Media, Pennsylvania was burgled by a group calling itself the Citizens' Commission to Investigate the FBI . Numerous files were taken and distributed to a range of newspapers, including The Harvard Crimson . The files detailed the FBI's extensive COINTELPRO program, which included investigations into lives of ordinary citizens—including

In 2003, a congressional committee called the FBI's organized crime informant program "one of the greatest failures in the history of federal law enforcement." The FBI allowed four innocent men to be convicted of the March 1965 gangland murder of Edward "Teddy" Deegan in order to protect Vincent Flemmi , an FBI informant. Three of

A leading U.S. counterterrorism , counterintelligence , and criminal investigative organization,
1827-648: The Communications Act of 1934 , which outlawed non-consensual phone tapping, but did allow bugging. In the 1939 case Nardone v. United States , the court ruled that due to the 1934 law, evidence the FBI obtained by phone tapping was inadmissible in court. After Katz v. United States (1967) overturned Olmstead , Congress passed the Omnibus Crime Control Act , allowing public authorities to tap telephones during investigations, as long as they obtained warrants beforehand. Beginning in

#17327945858421914-706: The Economic Espionage Act (EEA, 1996), the FBI followed suit and underwent a technological upgrade in 1998, just as it did with its CART team in 1991. Computer Investigations and Infrastructure Threat Assessment Center (CITAC) and the National Infrastructure Protection Center (NIPC) were created to deal with the increase in Internet -related problems, such as computer viruses, worms, and other malicious programs that threatened U.S. operations. With these developments,
2001-681: The Gameover ZeuS botnet which had been used to distribute CryptoLocker and other malware. The Department of Justice also publicly issued an indictment against the Russian hacker Evgeniy Bogachev for his alleged involvement in the botnet. As part of the operation, the Dutch security firm Fox-IT was able to procure the database of private keys used by CryptoLocker; in August 2014, Fox-IT and fellow firm FireEye introduced an online service which allows infected users to retrieve their private key by uploading
2088-670: The January 6, 2021 attack on democratic institutions in Washington D.C. later testified in support of the Proud boys , who were part of the plot. Revelations about the informant raised fresh questions about intelligence failures by the FBI before the riot. According to the Brennan Center , and Senate committees , the FBI's response to white supremacist violence was "woefully inadequate". The FBI has long been suspected to have turned
2175-477: The Osage Indian murders . During the "War on Crime" of the 1930s, FBI agents apprehended or killed a number of notorious criminals who committed kidnappings, bank robberies, and murders throughout the nation, including John Dillinger , "Baby Face" Nelson , Kate "Ma" Barker , Alvin "Creepy" Karpis , and George "Machine Gun" Kelly . Other activities of its early decades focused on the scope and influence of

In the early 18th century, the custom was that the captain of a captured vessel gave a bond or "ransom bill", leaving one of his crew as a hostage or "ransomer" in the hands of
2349-498: The U.S. Secret Service , for personnel, investigators in particular. On May 27, 1908, Congress forbade this use of Treasury employees by the Justice Department, citing fears that the new agency would serve as a secret police department. Again at Roosevelt's urging, Bonaparte moved to organize a formal Bureau of Investigation , which would then have its own staff of special agents . The Bureau of Investigation (BOI)

It then attempts to contact one of several designated command and control servers; once connected, the server generates a 2048-bit RSA key pair, and sends the public key back to the infected computer. The server may be a local proxy and go through others, frequently relocated in different countries to make tracing them more difficult. The payload then encrypts files across local hard drives and mapped network drives with
2523-581: The white supremacist group Ku Klux Klan , a group with which the FBI was evidenced to be working in the Viola Liuzzo lynching case. Earlier, through the work of Edwin Atherton , the BOI claimed to have successfully apprehended an entire army of Mexican neo-revolutionaries under the leadership of General Enrique Estrada in the mid-1920s, east of San Diego, California. Hoover began using wiretapping in
2610-563: The 1920s during Prohibition to arrest bootleggers. In the 1927 case Olmstead v. United States , in which a bootlegger was caught through telephone tapping, the United States Supreme Court ruled that FBI wiretaps did not violate the Fourth Amendment as unlawful search and seizure, as long as the FBI did not break into a person's home to complete the tapping. After Prohibition's repeal, Congress passed
2697-462: The 1940s and continuing into the 1970s, the bureau investigated cases of espionage against the United States and its allies. Eight Nazi agents who had planned sabotage operations against American targets were arrested, and six were executed ( Ex parte Quirin ) under their sentences. Also during this time, a joint US/UK code-breaking effort called "The Venona Project "—with which the FBI

2784-586: The Bureau agreed to identify, review, and release all pertinent cases, and notify prosecutors about cases in which faulty testimony was given. In 2012, the FBI formed the National Domestic Communications Assistance Center to develop technology for assisting law enforcement with technical knowledge regarding communication services, technologies, and electronic surveillance. An FBI informant, who participated in
2871-666: The Bureau of Investigation, the BOI or BI for short. Its name was changed to the Federal Bureau of Investigation (FBI) in 1935. The FBI headquarters is the J. Edgar Hoover Building in Washington, D.C. The FBI has a list of the top 10 most wanted fugitives . The mission of the FBI is to "protect the American people and uphold the Constitution of the United States ". Currently, the FBI's top priorities are: In
2958-617: The FBI created the Top Hoodlum Program. The national office directed field offices to gather information on mobsters in their territories and to report it regularly to Washington for a centralized collection of intelligence on racketeers . After the Racketeer Influenced and Corrupt Organizations Act , for RICO Act, took effect, the FBI began investigating the former Prohibition-organized groups, which had become fronts for crime in major cities and small towns. All
3045-699: The FBI has jurisdiction over violations of more than 200 categories of federal crimes . Although many of the FBI's functions are unique, its activities in support of national security are comparable to those of the British MI5 and NCA , the New Zealand GCSB and the Russian FSB . Unlike the Central Intelligence Agency (CIA), which has no law enforcement authority and is focused on intelligence collection abroad,
3132-647: The FBI increased its electronic surveillance in public safety and national security investigations, adapting to the telecommunications advancements that changed the nature of such problems. During the September 11, 2001, attacks on the World Trade Center , FBI agent Leonard W. Hatton Jr. was killed during the rescue effort while helping the rescue personnel evacuate the occupants of the South Tower, and he stayed when it collapsed. Within months after
3219-534: The FBI is primarily a domestic agency, maintaining 56 field offices in major cities throughout the United States, and more than 400 resident agencies in smaller cities and areas across the nation. At an FBI field office, a senior-level FBI officer concurrently serves as the representative of the director of national intelligence . Despite its domestic focus, the FBI also maintains a significant international footprint, operating 60 Legal Attache (LEGAT) offices and 15 sub-offices in U.S. embassies and consulates across
3306-490: The FBI work was done undercover and from within these organizations, using the provisions provided in the RICO Act. Gradually the agency dismantled many of the groups. Although Hoover initially denied the existence of a National Crime Syndicate in the United States, the Bureau later conducted operations against known organized crime syndicates and families, including those headed by Sam Giancana and John Gotti . The RICO Act
3393-563: The FBI's auto mechanics and janitors. For over 40 years, the FBI crime lab in Quantico had believed that lead alloys used in bullets had unique chemical signatures. It was analyzing the bullets with the goal of matching them chemically, not only to a single batch of ammunition coming out of a factory, but also to a single box of bullets. The National Academy of Sciences conducted an 18-month independent review of comparative bullet-lead analysis . In 2003, its National Research Council published
3480-649: The FBI, CIA, and the rest of the United States Intelligence Community . The book blamed the FBI's decentralized structure, which prevented effective communication and cooperation among different FBI offices. The book suggested that the FBI had not evolved into an effective counter-terrorism or counter-intelligence agency, due in large part to deeply ingrained agency cultural resistance to change. For example, FBI personnel practices continued to treat all staff other than special agents as support staff, classifying intelligence analysts alongside
3567-503: The FBI, and the Origins of 9/11 . The Post reported, from Zegart's book, that government documents showed that both the CIA and the FBI had missed 23 potential chances to disrupt the terrorist attacks of September 11, 2001. The primary reasons for the failures included: agency cultures resistant to change and new ideas; inappropriate incentives for promotion; and a lack of cooperation between

3654-454: The FBI. While the FBI did accede to most of the recommendations, including oversight by the new director of National Intelligence , some former members of the 9/11 Commission publicly criticized the FBI in October 2005, claiming it was resisting any meaningful changes. On July 8, 2007, The Washington Post published excerpts from UCLA Professor Amy Zegart's book Spying Blind: The CIA,
3741-495: The September 11, 2001, attacks. The 9/11 Commission 's final report on July 22, 2004, stated that the FBI and Central Intelligence Agency (CIA) were both partially to blame for not pursuing intelligence reports that could have prevented the September 11 attacks. In its most damning assessment, the report concluded that the country had "not been well served" by either agency and listed numerous recommendations for changes within
3828-679: The United States, including both militant and non-violent organizations. Among its targets was the Southern Christian Leadership Conference , a leading civil rights organization whose clergy leadership included the Rev. Dr. Martin Luther King Jr. . The FBI frequently investigated King. In the mid-1960s, King began to criticize the Bureau for giving insufficient attention to the use of terrorism by white supremacists. Hoover responded by publicly calling King
3915-412: The absence of current backups ( offline backups made before the infection that are inaccessible from infected computers cannot be attacked by CryptoLocker). Due to the length of the key employed by CryptoLocker, experts considered it practically impossible to use a brute-force attack to obtain the key needed to decrypt files without paying ransom; the similar 2008 trojan Gpcode.AK used a 1024-bit key that

Between 1993 and 1996, the FBI increased its counter-terrorism role following the first 1993 World Trade Center bombing in New York City , the 1995 Oklahoma City bombing , and the arrest of the Unabomber in 1996. Technological innovation and
4089-479: The attackers but their files were not decrypted. In November 2013, the operators of CryptoLocker launched an online service that claimed to allow users to decrypt their files without the CryptoLocker program, and to purchase the decryption key after the deadline had expired; the process involved uploading an encrypted file to the site as a sample and waiting for the service to find a match; the site claimed that
4176-510: The attacks, FBI Director Robert Mueller , who had been sworn in a week before the attacks, called for a re-engineering of FBI structure and operations. He made countering every federal crime a top priority, including the prevention of terrorism, countering foreign intelligence operations, addressing cybersecurity threats, other high-tech crimes, protecting civil rights, combating public corruption, organized crime, white-collar crime, and major acts of violent crime. In February 2001, Robert Hanssen
4263-585: The captor. Frequent mention is made of the taking of French privateers which had in them ten or a dozen ransomers. The owner could be sued on his bond. Payment of ransom was banned by the Parliament of Great Britain in 1782 although this was repealed in 1864. It was generally allowed by other nations. In the Russo-Japanese War , though no mention was made of ransom, the contributions levied by invading armies might still be accurately described by

The program was expanded further by this executive order by making all federal employment of homosexuals illegal. On July 8, 1953, the FBI forwarded to the U.S. Civil Service Commission information from the sex deviates program. Between 1977 and 1978, 300,000 pages in

CryptoLocker was isolated in late May 2014 via Operation Tovar , which took down the Gameover ZeuS botnet that had been used to distribute the malware. During the operation, a security firm involved in the process obtained the database of private keys used by CryptoLocker, which was in turn used to build an online tool for recovering the keys and files without paying
4611-550: The fiscal year 2019, the Bureau's total budget was approximately $ 9.6 billion. In the Authorization and Budget Request to Congress for fiscal year 2021, the FBI asked for $ 9,800,724,000. Of that money, $ 9,748,829,000 would be used for Salaries and Expenses (S&E) and $ 51,895,000 for Construction. The S&E program saw an increase of $ 199,673,000. In 1896, the National Bureau of Criminal Identification

The FBI can and does at times carry out secret activities overseas, just as the CIA has a limited domestic function . These activities generally require coordination across government agencies. The FBI was established in 1908 as
4785-412: The government. Hoover was substantially involved in most major cases and projects that the FBI handled during his tenure. But as detailed below, his tenure as Bureau director proved to be highly controversial, especially in its later years. After Hoover's death, Congress passed legislation that limited the tenure of future FBI directors to ten years. Early homicide investigations of the new agency included
4872-425: The handwriting of the kidnapper, leading to the phrase ransom note effect being used to describe documents containing jarringly mixed fonts. An early use of this technique in film is in the 1952 film The Atomic City . In some instances, a person may forge a ransom note in order to falsely collect a ransom despite not having an actual connection to the kidnapper. On other occasions, a ransom note has been used as

Robert Shivers, head of the Honolulu office, obtained permission from Hoover to start detaining those on the list on December 7, 1941, while bombs were still falling over Pearl Harbor . Mass arrests and searches of homes, in most cases conducted without warrants, began

Experts suggested precautionary measures, such as using software or other security policies to block the CryptoLocker payload from launching. Due to the nature of CryptoLocker's operation, some experts reluctantly suggested that paying the ransom was the only way to recover files from CryptoLocker in

Two of the four men died in prison after serving almost 30 years, and two others were released after serving 32 and 36 years. In July 2007, U.S. District Judge Nancy Gertner in Boston found that the Bureau had helped convict the four men using false witness accounts given by mobster Joseph Barboza . The U.S. Government

#17327945858425394-457: The name. Although ransom is usually demanded only after the kidnapping of a person, it is not unheard of for thieves to demand ransom for the return of an inanimate object or body part. In 1987, thieves broke into the tomb of Argentinian president Juan Perón and then severed and stole his hands ; they later demanded $ 8 million US for their return. The ransom was not paid. The practice of towing vehicles and charging towing fees for

For example, if a ransom note contains misspellings, a suspect might be asked to write a sample of text to determine if they make the same spelling errors. Following cases where forensic evidence pinpointed particular typewriters to typed ransom notes, kidnappers started to use pre-printed words assembled from different newspapers. In popular culture, ransom notes are often depicted as being made from words in different typefaces clipped from different sources (typically newspapers), in order to disguise
5568-485: The operators were believed to have extorted a total of around $ 3 million. The success of CryptoLocker spawned a number of unrelated and similarly named ransomware trojans working in essentially the same way, including some that refer to themselves as "CryptoLocker"—but are, according to security researchers, unrelated to the original CryptoLocker. In September 2014, further clones such as CryptoWall and TorrentLocker (whose payload identifies itself as "CryptoLocker", but

The process only encrypts data files with certain extensions , including Microsoft Office , OpenDocument , and other documents, pictures, and AutoCAD files. The payload displays a message informing the user that files have been encrypted, and demands a payment of 400 USD or Euro through an anonymous pre-paid cash voucher (i.e. MoneyPak or Ukash ), or an equivalent amount in bitcoin (BTC) within 72 or 100 hours (while starting at 2 BTC,
5829-413: The ransom price has been adjusted down to 0.3 BTC by the operators to reflect the fluctuating value of bitcoin), or else the private key on the server would be destroyed, and "nobody and never [ sic ] will be able to restore files." Payment of the ransom allows the user to download the decryption program, which is pre-loaded with the user's private key. Some infected victims claim that they paid

Following the shutdown of the botnet that had been used to distribute CryptoLocker, it was calculated that about 1.3% of those infected had paid the ransom; many had been able to recover files which had been backed up, and others are believed to have lost huge amounts of data. Nonetheless,
