Summary
The use of Signal, a privacy-focused messaging app, has been compromised by Russian-aligned threat actors. This compromise involves exploiting the app's legitimate "linked devices" feature, which allows users to access their account on multiple devices.This technique is novel and widely used, making it a significant security concern for the app and its users.
