Russian Hacking Campaign Exposes Weakness in Signal's Cybersecurity A recent hacking campaign targeting Signal users, allegedly linked to Russian government spies, highlights the need for greater vigilance and security measures in encrypted messaging apps.
Donncha Ó Cearbhaill, a renowned security researcher, discovered this campaign after receiving an unusual message on his own Signal account, claiming to be from the app's security support team.
Ó Cearbhaill was able to turn the tables on the hackers by analyzing their system, known as "ApocalypseZ," which automates the attack process and allows hackers to target multiple people simultaneously with minimal human oversight.
