(Reuters) - A Russian man was sentenced in Manhattan federal court to 12 years in prison on Thursday for his involvement in a massive computer hacking scheme that targeted JPMorgan Chase & Co and other financial services companies.

U.S. District Judge Laura Taylor Swain said during a videoconference hearing that the sentence for Andrei Tyurin, 37, was appropriate, given his involvement in a "sprawling financial criminal enterprise" from 2007 to 2015 that prosecutors say harvested the personal information of 138 million people in the United States for use in other schemes.

Acting U.S. Attorney Audrey Strauss said: "Andrei Tyurin played a major role in orchestrating and facilitating an international hacking campaign that included one of the largest thefts of U.S. customer data from a single financial institution in history."

Tyurin had pleaded guilty in September 2019 to six counts including wire fraud and computer hacking conspiracy and agreed to forfeit the $19.2 million he was paid for the hacking.

Four companies targeted in the hacks seek $19.9 million in restitution from Tyurin for the cost of shoring up their digital security and buying credit monitoring for customers, Manhattan federal prosecutor Eun Young Choi said during the hearing. The restitution amount will be set at a separate hearing on April 6.

Prosecutors had sought a sentence of more than 15 years to deter others, while Tyurin's attorney Florian Miedel of Miedel & Mysliwiec urged the judge for a lower sentence, accounting for the fact that Tyurin had never stolen customer funds and that his detention during the pandemic, during which he contracted COVID-19, has been particularly harsh. Tyurin is married and has a young daughter in Russia.

"Any time a sentence is intended to send a message, the defendant is treated as a symbol, as an example of a class of people, rather than an individual," Miedel said.

Judge Swain said she had taken all of those factors into account, and that the sentence should deter Tyurin, who has an aptitude for hacking and would not be extraditable after he serves his sentence and is deported to Russia.

Tyurin apologized during the hearing.

"I regret what I have done, but unfortunately I cannot turn back time," he said through an interpreter.

Tyurin was arrested in the country of Georgia at the request of U.S. authorities in 2018, as one of several people charged with taking part in the scheme.

JPMorgan disclosed it had been hacked in 2014, saying it had exposed information associated with about 83 million customer accounts. Other victims included E*Trade Financial Corp, Scottrade Inc and News Corp's Dow Jones & Co, publisher of The Wall Street Journal.

Prosecutors had previously charged two Israeli citizens, Gery Shalon and Ziv Orenstein, along with an American resident of Israel, Joshua Samuel Aaron, in connection with the scheme. Members of the conspiracy made hundreds of millions of dollars through criminal schemes using stolen information, prosecutors said.

The case is U.S. v. Shalon et al, No. 15-cr-00333, U.S. District Court, Southern District of New York.
