Bruce66423 writes with news of an electronic attack believed to affect at least five U.S. banking institutions this month, including JP Morgan, now being investigated by the FBI. According to the Independent, The attack on JP Morgan reportedly resulted in the loss of “gigabytes of sensitive data” that could have involved customer and employee information. It is said to have been of a level of sophistication beyond ordinary criminals, leading to speculation of a state link. The FBI is thought to be investigating whether there is a connection to Russia. American-Russian relations continue to be fraught amid the crisis in Ukraine, with sanctions ramped up. Bruce66423 asks "The quality of the attack, which appears to have led to 'gigabytes' of data being lost, is raising the prospect of a state being the source. The present culprit suggested is Russia... why the assumption it's not China — just because China isn't invading the Ukraine at the moment?" News of the attack is also at the New York Times, which notes Earlier this year, iSight Partners, a security firm in Dallas that provides intelligence on online threats, warned companies that they should be prepared for cyberattacks from Russia in retaliation for Western economic sanctions. But Adam Meyers, the head of threat intelligence at CrowdStrike, a security firm that works with banks, said that it would be “premature” to suggest the attacks were motivated by sanctions.
