How to Stop the Java Zero-Day Exploit

Follow our tips to disable Java in your browsers and stay protected from this active exploit

New Java zero-day exploit adopted by online criminals

Right now cybercriminals are exploiting a zero-day vulnerability in Java that could lead to your computer becoming infected by malware. Although Oracle has known about the vulnerability since April, the company has only just issued a patch to fix the problem and other vulnerabilities affecting Java 6 and Java 7. That's why you should take action now and deploy the patch to protect yourself against these exploits.

We now know that cybercriminals are currently using an exploit that affects Java 7 running on all browsers and operating systems (Windows, OS X and Linux). Criminals have exploited similar flaws in Java to infect more than 600,000 Macs with the Flashback malware.

We also recommend that you seriously consider disabling Java in your browsers to stay protected against these security holes.

Should I disable Java in my browser?

You can do something right now to stay safe from attackers exploiting Java. Even if you absolutely must use websites that require you to have Java installed, why not disable it in your main browser and have an alternative browser just for visiting that website?

Follow these links below for instructions from our experts at Naked Security, explaining how to disable Java in all of the most popular browsers.
