Java PC software open to indefensible attacks

Computer security firms are urging PC users to disable Java software in their browsers due to the risk of defenceless hacker attacks.

The widely installed free software from Oracle opens computers to security threats which experts say are impossible to combat.

Warnings from Rapid 7, AlienVault and other online security companies advise users to immediately disable Java software with the system currently sitting on 97% of enterprise desktops.

Experts say a flaw in the latest version of Java is allowing a second piece of software called ‘Poison Ivy’ to let hackers gain control of an infected computer and form an attack.

"If exploited, the attacker will be able to perform any action the victim can perform on the victim's machine," says Tod Beardsley, engineering manager Rapid 7.

Computers can get infected without their users' knowledge through visiting any website which has been compromised by hackers.

An Oracle spokeswoman declined to comment but Rapid7 has set up a web page informing users of the risks
