Cybersecurity researchers have uncovered dozens of attacks that involve malicious updates for Chrome browser extensions, one week after a security firm was compromised in a similar incident.
As of Wednesday, a total of 36 Chrome extensions injected with data-stealing code have been detected, mostly related to artificial intelligence (AI) tools and virtual private networks (VPNs), according to a report by ExtensionTotal, a platform that analyzes extensions listed on various marketplaces and public registries.
These extensions, collectively used by roughly 2.6 million people, include third-party tools such as ChatGPT for Google Meet, Bard AI Chat, YesCaptcha Assistant, VPNCity and Internxt VPN. Some of the affected companies have already addressed the issue by removing the compromised extensions from the store or updating them, according to ExtensionTotal's analysis.
In the incident targeting security firm Cyberhaven last week, an unidentified threat actor compromised one of the startup's administrative accounts through a phishing email. This allowed the attacker to publish a new version of the extension containing malicious code.
