BlueMoon, a shared Chrome and Windows exploit kit, shows why “patch later” is becoming a dangerous gamble.
Security updates are easy to put off. The browser still opens, Windows still works, and choosing to relaunch your browser or restart your computer later can feel harmless.
But a newly documented exploit kit called “BlueMoon” shows how quickly patching delays can become dangerous. Proofpoint Researchers found four espionage groups using the same exploit chain against Chrome browsers running on Windows within days of one another.
The campaign is a timely reminder that once a security flaw, or even its fix, becomes public, attackers may move faster than many users expect.
The attacks began with phishing emails. A victim who clicked a malicious link could be sent to a web page designed to exploit two vulnerabilities in Chrome’s V8 JavaScript engine, followed by a Windows vulnerability to break out of the browser’s protections and gain higher privileges on the computer.
