Attack of The Extensions
SpecterOps demonstrates how attackers can silently side-load Chromium extensions to establish browser-resident C2 channels, enabling persistent cookie theft that evades most endpoint controls.
Summary written by editorial AI · Source link below
TL;DR: Browser extensions can turn Chromium into a persistent foothold. This post introduces a way to silently install extensions turning Chromium browsers into a command and control (C2) platform for persistent cookie theft. Intro This blog is a continuation of Dough No! Revisiting Cookie Theft. In the previous blog, we looked at how Chromium’s Application […] The post Attack of The Extensions appeared first on SpecterOps .
Editorial Analysis
Browser-based C2 persistence evades traditional EDR and proxy controls; enterprises relying on Chromium without extension allow-lists face a blind spot that attackers are now actively weaponising.
Enforce a strict Chromium extension allow-list via Group Policy and monitor for unsigned or developer-mode extension installations.
Browsers can be silently turned into attacker footholds; extension allow-listing is a low-cost control that closes this gap.
