Nano Adblocker & Nano Defender: Removed or Compromised

What happened

These two well-known ad-blocking extensions were sold to a new developer in October 2020. The new owner shipped an update that added malicious code which read users' session data and sent requests to a remote server — effectively turning the ad blockers against their users. They were pulled from the Chrome Web Store after the abuse was disclosed.

What affected users could do

Affected users had to remove the Chrome versions immediately and move to the original, still-trustworthy Firefox builds or a vetted alternative such as uBlock Origin. Reviewing an extension's ownership history is the lesson here.
