Edge Add-ons

Microsoft Edge browser extensions

Microsoft Edge Add-ons is a Chromium store with a fraction of Chrome's volume (around 3,000 listings tracked) but the same extension model and the same attack surface, since most Chrome extensions can be re-packaged for Edge. The campaigns we track here — including the Edge half of RedDirection — arrived exactly that way: previously clean extensions that turned with an update. Scorecards below cover permissions, malware signatures, secrets, and network indicators for the full catalog.

• –Chrome extensions re-packaged for Edge with altered update paths
• –Previously-clean listings turned malicious via auto-update, as in RedDirection
• –Sideloading attacks that forge Chrome/Edge preference integrity checks
