Researchers have flagged five separate malicious Chrome extensions masquerading as Netflix viewers and more. They track user activity and insert code into any e-commerce sites they visit, letting cyberattackers steal payments through the retailer affiliate programs. 

McAfee Labs analysts found the Chrome extensions being marketed to let users watch Netflix in groups, automatically clip coupons, and take screenshots. All together, the apps have been downloaded 1.4 million times, they found.

The researchers warn end users to take extra precautions to verify an extension’s safety if it asks for additional permissions. 

“This blog highlights the risk of installing extensions, even those that have a large install base as they can still contain malicious code,” they said.
