Extensions installed on almost 1 million devices have been overriding key security protections to turn browsers into engines that scrape websites on behalf of a paid service, a researcher said.
The 245 extensions, available for Chrome, Firefox, and Edge, have racked up nearly 909,000 downloads, John Tuckner of SecurityAnnex reported. The extensions serve a wide range of purposes, including managing bookmarks and clipboards, boosting speaker volumes, and generating random numbers. The common thread among all of them: They incorporate MellowTel-js, an open source JavaScript library that allows developers to monetize their extensions.
Tuckner and critics say the monetization works by using the browser extensions to scrape websites on behalf of paying customers, which include AI startups, according to MellowTel founder Arsian Ali. Tuckner reached this conclusion after uncovering close ties between MellowTel and Olostep, a company that bills itself as "the world's most reliable and cost-effective Web scraping API." Olostep says its service “avoids all bot detection and can parallelize up to 100K requests in minutes.” Paying customers submit the locations of browsers they want to access specific webpages. Olostep then uses its installed base of extension users to fulfill the request.
As many of us celebrated the year-end holidays, a small group of researchers worked overtime tracking a startling discovery: At least 33 browser extensions hosted in Google’s Chrome Web Store, some for as long as 18 months, were surreptitiously siphoning sensitive data from roughly 2.6 million devices.
The compromises came to light with the discovery by data loss prevention service Cyberhaven that a Chrome extension used by 400,000 of its customers had been updated with code that stole their sensitive data.
The malicious extension, available as version 24.10.4, was available for 31 hours, from December 25 at 1:32 AM UTC to Dec 26 at 2:50 AM UTC. Chrome browsers actively running Cyberhaven during that window would automatically download and install the malicious code. Cyberhaven responded by issuing version 24.10.5, and 24.10.6 a few days later.
