Cybercriminals hijacked a major bank’s online banking, mobile, point-of-sale, ATM, and investment transactions in a five-hour heist. The bank, which has $25 billion in assets, 5 million customers worldwide, and 500 branches in Brazil, Argentina, the US, and the Cayman Islands, was locked out of its network and systems during the attack. Researchers estimate that hundreds of thousands or possibly millions of the bank’s customers may have been victimized during the hijack window.”]
