Signal Under Siege: Russian Hackers Target Secure Messaging Apps with Phishy Tactics
Russia-aligned threat actors are targeting Signal accounts using the “linked devices” feature to eavesdrop on messages. Malicious QR codes masquerade as legitimate invites, tricking victims into linking their account to hacker-controlled devices. As cyber espionage escalates, protecting secure messaging apps like Signal is more crucial than ever.
Hot Take:
In a plot twist that even James Bond would envy, Russian hackers have found a way to hack into Signal, the app that’s supposed to be the Fort Knox of messaging. Using QR codes for evil, these cyber tricksters are turning privacy features into their own little spy tools. It’s like they’ve turned Signal into their personal game of ‘I Spy’—except with real people’s conversations. Who knew QR codes could be so sinister? Time to inspect every QR code like it’s a suspicious-looking suitcase at the airport!
