Russian Hackers Phishing Signal Users, FBI and CISA Warn
US agencies alert that Russian intelligence-linked hackers are running phishing campaigns against Signal and other messaging app users.
The FBI and CISA have issued a joint warning: hackers connected to Russian intelligence services are actively phishing users of encrypted messaging apps, with Signal squarely in the crosshairs.
The advisory follows similar alerts already issued by security agencies in the Netherlands and Germany. The pattern is clear — Russian-linked threat actors are systematically going after users who rely on secure messaging platforms, likely hoping to compromise communications they can't otherwise intercept.
Signal has long been a go-to for journalists, activists, and security-conscious users precisely because of its end-to-end encryption. That makes social engineering the path of least resistance for attackers who can't crack the crypto itself.
The takeaway is blunt: encryption doesn't help if you hand over your credentials to a phishing page. Even Signal users need to stay paranoid about suspicious links and device-linking requests.
