[ISN] Hacking Team’s Leak Helped Researchers Hunt Down a Zero-Day

www.wired.com/2016/01/hacking-team-leak-helps-kaspersky-researchers-find-zero-day-exploit/ By Kim Zetter Security Wired.com 01/13/16 ZERO-DAY EXPLOITS ARE a hacker’s best friend. They attack vulnerabilities in software that are unknown to the software maker and are therefore unpatched. Criminal hackers and intelligence agencies use zero day exploits to open a stealth door into your system, and because antivirus companies also don’t know about them, the exploits can remain undetected for years before they’re discovered. Until now, they’ve usually been uncovered only by chance. But researchers at Kaspersky Lab have, for the first time, discovered a valuable zero-day exploit after intentionally going on the hunt for it. And they did so by using only the faintest of clues to find it. The malware they found is a remote-code execution exploit that attacks a vulnerability in Microsoft’s widely used Silverlight software—a browser plug-in Netflix and other providers use to deliver streaming content to users. It’s also used in SCADA and other industrial control systems that are installed in critical infrastructure and industrial facilities. The vulnerability, which Microsoft called “critical” in a patch released to customers on Tuesday, would allow an attacker to infect your system after getting you to visit a malicious website where the exploit resides—usually through a phishing email that tricks you into clicking on a malicious link. The attack works with all of the top browsers except Chrome—but only because Google removed support for the Silverlight plug-in in its Chrome browser in 2014. […]
