Russian ransomware group LockBit claims it has breached the U.S. Federal Reserve and is threatening to release 33 terabytes of sensitive data, including "Americans' banking secrets," on Tuesday. "33 terabytes of juicy banking information containing Americans' banking secrets," LockBit wrote Sunday on its data leak site. "You better hire another negotiator within 48 hours, and fire this clinical idiot who values Americans' bank secrecy at $50,000," the group added. While the Federal Reserve has not confirmed the hack, a number of cybersecurity experts are discounting LockBit's claims, saying there are no published samples of the stolen data.
