Chrome extensions with 13.4 million installs caught hijacking searches

By Bill Toulas

AI Summary

Researchers identified 319 malicious Chrome extensions with a combined 13.4 million reported installs that hijacked users' search queries by routing them through attacker-controlled tracking servers, generating advertising revenue via Bing and Yahoo. The campaign operated at scale while evading detection due to the extensions' legitimate-appearing functionality. Security teams managing enterprise browser environments should audit installed extensions against the identified IOCs.
