Signal Sabotage: How Hackers Turned a Secure Messenger into a Malware Machine
Ukraine’s CERT-UA reports cyberattacks using compromised Signal accounts to deliver malware to defense staff. These messages, often disguised as meeting reports, lure targets with familiar contacts. Once opened, they deploy DarkTortilla to execute the Dark Crystal RAT. Signal users are advised to disable auto-downloads and check linked devices to avoid such attacks.
Hot Take:
