US Offers $10 Million Bounty Over Signal and WhatsApp Hacking Spree

Federal authorities are offering a reward of up to $10 million for information leading to the identification or location of a Russian state cyber group that has compromised thousands of Signal and WhatsApp accounts belonging to investigative reporters and US government employees.

The campaign, attributed to two Russia-state groups tracked as UNC5792 and UNC4221, has been ongoing since at least March. The reward is offered under the State Department's Rewards for Justice program.
