Summary
Security researchers have identified a highly targeted social engineering campaign (REF6598) that weaponizes the Obsidian note-taking application to deliver a previously undocumented Remote Access Trojan (RAT) named PHANTOMPULSE. The attack chain relies on tricking the user into enabling a community plugin, which then executes code to deploy the RAT. The attack, designated REF6598, is a multi-stage social engineering effort. Once the victim opens the shared vault, the infection is triggered by social engineering. The attack chain differs slightly between Windows and macOS but follows the same general principle:.
