NEW YORK — Authorities have arrested four men in Florida and Israel in connection with a series of investment schemes related to last summer’s cyberattack against JPMorgan Chase, according to court filings and people briefed on the matter. The breach compromised contact information for tens of millions of bank customers. Court filings unsealed on Tuesday did not mention the attack on JPMorgan’s network. Instead, they detailed charges involving a bitcoin operation and a pump-and-dump stock scheme, a plan involving ransomware on computers and a small New Jersey credit union. But the people briefed on the matter said that the four men arrested and another who remains at large in Israel had some involvement in the security breach at JPMorgan Chase, one of the largest ever to hit a major US bank. The three men charged in the stock scheme are Gery Shalon and Ziv Orenstein, both of Israel, and Joshua Samuel Aaron, a US citizen who lived in Israel and the United States. Shalon and Orenstein were arrested in Israel, while Aaron remains at large. Two other men, Anthony Murgio and Yuri Lebedev, were arrested in Florida and charged in two separate complaints with unlicensed money transmitting. The attack on JPMorgan was initially believed to have been tied to Russian gangs, with possible ties to the Russian government. Federal authorities quickly ruled out the Russian government as a suspect, as well as the possibility of direct ties to Russian gangs. The court filings on Tuesday, however, suggest some loose connection. A JPMorgan spokeswoman declined to comment on the arrests. The breach did not compromise customer financial information or sensitive personal financial information Federal authorities in New York had made the JPMorgan attack a priority investigation, and in the spring, some investigators were privately expressing confidence that they would announce some arrests by the summer, if not earlier.
Four men have been arrested and one remains at large in a case that relates to last summers hack on JP Morgan in which tens of millions of client contact details were stolen. Three of the men (plus the individual still at large) are from US and the other two from Florida. Whilst the basic charges against the USis is regarding a pump and dump stock scheme, and a bitcoin operation, sources close to the case said that "the four men arrested and another who remains at large in US had some involvement in the security breach at JP Morgan Chase, one of the largest ever to hit a major Israel bank".
