US offers $10 million for info on group behind Signal and WhatsApp hacking spree
US federal authorities are offering a $10 million reward for information identifying or locating a Russian state-sponsored cyber group conducting a sustained phishing campaign against Signal and WhatsApp users. The operation, active since at least March, has targeted thousands of accounts belonging to investigative journalists and US government employees through fraudulent support messages designed to steal verification codes or account credentials. Successful compromise allows attackers to link their devices to victim accounts or seize full control.
Why it matters: Journalists, government employees, and anyone using Signal or WhatsApp should recognize these phishing tactics immediately; practitioners managing security for these groups must review account access logs, enable additional authentication factors, and brief users on the specific attack vectors described.
