Overview

RedDirection weaponized previously-clean browser extensions by pushing malware in routine version updates. The extension code was clean for years before the malicious update landed on the existing install base.

Payload

Captured the URL of every page visited and exfiltrated it with a unique tracking ID to a C2 server, enabling browser hijacking, redirection to attacker-controlled sites, and credential theft via fake banking pages.

IOC note

No file hashes were published for this campaign — only extension IDs and install counts. The exact malicious version per extension was not disclosed (malware was injected across updates), so versions are left open.

Affected extensions (36)
