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. read full post
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.
How do I disable Java in my browser?
For Windows: go to Start > Control Panel, click the Uninstall a program link. Find Java on the list of programs. If you have version 7, uninstall it.
For Mozilla Firefox: From the main menu select Tools > Add-ons. In the Add-on management window, choose Plugins. Find any plugins on the list that say Java and click the Disable button. Restart Firefox.
For Google Chrome: Type “chrome://plugins/” (minus the quotes) into the browser address bar. Find any plugins on the list that say Java and click the Disable button.
For Internet Explorer: I have been told that disabling Java in IE is complicated. The U.S. Computer Emergency Response Team (USCERT) has some steps here. This may be a good time to switch to a different browser.
For Safari: Click Preferences > Security tab > uncheck the Enable Java option.
For Opera: Type “opera:plugins” (minus the quotes) into the browser’s address bar. Find any plugins on the list that say Java and click the Disable button.
For OS X 10.7 and 10.8: go to Macintosh HD/Library/Java/JavaVirtualMachines/ and remove the 1.7.0.jdk file. Older versions of OS X run Java 6.
Also, make sure that you have up-to-date antivirus protection because avast! detects the latest Java zero day exploit in real time as Java:Dong-A [Expl] . We would appreciate your recommendation as well. share with your Facebook friends and also inform them. Thank you!
