New details have emerged about a phishing campaign targeting Chrome browser extension developers that led to the compromise of at least thirty-five extensions to inject data-stealing code, including those from cybersecurity firm Cyberhaven.
Although initial reports focused on Cyberhaven's security-focused extension, subsequent investigations revealed that the same code had been injected into at least 35 extensions collectively used by roughly 2,600,000 people.
