An anonymous reader writes: Court documents unsealed yesterday tie together cybersecurity breaches at several different banks and financial institutions as being caused by the same group of criminals. "Hackers and conspirators in more than a dozen countries generated hundreds of millions of dollars in illicit proceeds on pump-and-dump stock schemes and particularly lucrative online gambling, prosecutors said. From 2012 to mid-2015, the suspects and their co-conspirators successfully manipulated dozens of publicly traded stocks, sent misleading pitches to clients of banks and brokerages whose e-mail addresses they'd stolen, and profited by using trading accounts set up under fake names, prosecutors said." The attacks were spread across 75 different companies in nations across the globe, and included collusion with corrupt government officials who ignored the problem. U.S. Attorney Preet Bharara said, "By any measure, the data breaches at these firms were breathtaking in scope and in size."
