Another Java exploit; disable immediately
A serious new vulnerability notice about Java exploits has been issued by the Department of Homeland Security’s Cybersecurity Division. Java 7 Update 10 and earlier contain a vulnerability that can allow a remote attacker to execute malware on vulnerable systems.
A French researcher called Kafeine discovered that a number of websites using the exploit are able to download files directly to the victim's computer, and execute actions such as installing ransomware. “Hundreds of thousands of hits daily where i found it,” he wrote on his blog. “This could be a mayhem.”
Disable Java in web browsers
Some webpages may include content or apps that use the Java plug-in. There is no fix for this yet, so it is recommended that you protect yourself by disabling Java in your particular browser. Please see our previous blog How do I disable Java in my browser for instructions.
For a higher level of security, it is possible to entirely prevent any Java apps from running in a browser by de-selecting Enable Java content in the browser in the Java Control Panel under the Security tab. Disabling Java through the Java Control Panel will disable Java in all browsers.
