“Assuming the BrowserGate allegations are true, LinkedIn users should consider reducing the amount of identifiable, trackable, or sensitive data their browser exposes, and organizations should treat LinkedIn as a potentially hostile web environment until facts are verified,” Levine said. “Even if BrowserGate is exaggerated, browser fingerprinting is a real, widespread practice across the web. Treat LinkedIn like any other third-party data collector. LinkedIn has historically been treated as safe, [but] that assumption may need to be revisited.”
Levine said IT executives should “assume that LinkedIn can map your tech stack” and that, if the claims are accurate, LinkedIn could infer “which SaaS tools your employees use, which competitors you rely on, which job search tools your staff is using and which political/religious extensions appear inside your workforce.”
He added that IT should consider blocking LinkedIn on sensitive networks, or require it to only be accessed through VDI, as well as employing browser isolation techniques. Some companies might even want to use a separate isolated browser solely for LinkedIn, or, he said, “use a sandboxed browser session, such as Browserling or other cloud-isolated browsers.”
