The U.S. Department of State is offering up to $10 million for information that helps identify or locate members of two suspected hacker groups, UNC5792 and UNC4221. Multiple reports say the groups are linked to Russia’s intelligence and military services. The investigation focuses on alleged attacks against users of encrypted messaging platforms, including WhatsApp and Signal.
According to the accounts, the hacking activity has been ongoing since at least March, and it targets individuals who use those services. The Department of State’s reward is intended to support efforts to track down those behind the intrusions and to gather actionable information that could assist law enforcement.
Both outlets describe the offer as part of a broader U.S. effort to disrupt cyber operations attributed to state-linked groups. The reports do not indicate that the alleged attacks have been fully mitigated, but they characterize the campaign as active and tied to the named organizations.
