Really a bad weekend for Internet users. Three previously unknown critical zero-day vulnerabilities were revealed in Adobe’s Flash Player over the weekend, thanks to Hacking team data Breach in which 400GB of internal data were leaked over the Internet. Now, a new zero-day vulnerability has been reported in Oracle’s Java that is reportedly being exploited in the wild by hackers to target government armed forces. Cybercriminals are actively exploiting the Java-based zero-day flaw in an attempt to target U.S. defense agencies and members of NATO, Trend Micro security researchers warned in a blog post published Sunday.
