Exclusive: Massive spying on users of Google's Chrome shows new security weakness

A newly discovered spyware effort attacked users through 32 million downloads of extensions to Google’s market-leading Chrome web browser, researchers at Awake Security told Reuters, highlighting the tech industry’s failure to protect browsers as they are used more for email, payroll and other sensitive functions.

Alphabet Inc’s (GOOGL.O) Google said it removed more than 70 of the malicious add-ons from its official Chrome Web Store after being alerted by the researchers last month.

“When we are alerted of extensions in the Web Store that violate our policies, we take action and use those incidents as training material to improve our automated and manual analyses,” Google spokesman Scott Westover told Reuters.

Most of the free extensions purported to warn users about questionable websites or convert files from one format to another. Instead, they siphoned off browsing history and data that provided credentials for access to internal business tools.
