Almost 7 million users have attempted to install malicious browser extensions since 2020, with 70% of those extensions used as adware to target users with advertisements.
The most common payloads carried by malicious web browser extensions during the first half of 2022 belonged to adware families, snooping on browsing activity and promoting affiliate links.
This finding is based on telemetry data collected by Kaspersky, which reports over 1,300,000 attempts by users to install malicious extensions throughout H1 ‘22, an increase compared to last year’s figures.
