At the time, the
mass media claimed he was a
mathematician and had a degree in
biochemistry from
Saint Petersburg State Institute of Technology. According to the coverage, in 1994 Levin accessed the accounts of several large corporate customers of Citibank via their dial-up wire transfer service (Financial Institutions Citibank Cash Manager) and transferred funds to accounts set up by accomplices in Finland, the United States, the Netherlands, Germany and Israel. Three of his accomplices were arrested attempting to withdraw funds in
Tel Aviv,
Rotterdam and
San Francisco. Interrogation of his accomplices directed investigations to Levin, who was then working as a computer programmer for
St. Petersburg-based computer company AO Saturn. However, Russia's Constitution prohibits the extradition of its citizens to foreign countries. In March 1995, Levin was lured to London and apprehended at London's
Stansted Airport by
Scotland Yard officers when making an interconnecting flight from
Moscow. Levin's lawyers fought against extradition to the U.S., but their appeal was rejected by the
House of Lords in June 1997. Levin was delivered into U.S. custody in September 1997 and was tried in the
United States District Court for the Southern District of New York. In his plea agreement, he admitted to only one count of
conspiracy to
defraud and to
stealing US$3.7 million. In February 1998, he was convicted and sentenced to three years in jail, and ordered to make a
restitution of US$240,015. Citibank claimed that all but US$400,000 of the stolen US$10.7 million had been recovered. After the compromise of their system, Citibank updated their systems to use Dynamic Encryption Card, a physical authentication token. However, it was not revealed how Levin had gained access to the relevant account access details. Following his arrest in 1995, anonymous members of
hacking groups based in St. Petersburg claimed that Levin did not have the technical abilities to break into Citibank's systems, that they had cultivated access to systems deep within the bank's network, and that these access details had been sold to Levin for $100. == The revelation a decade later ==
