McAfee says it has found the biggest series of cyberattacks to date involving the infiltration of the networks of 72 organisations, including the UN.

The public website of the US Central Intelligence Agency went down on Wednesday as the hacker group Lulz Security said it had launched an attack.

A cybersecruty expert said the intruders’ goal had been to install software that would give a nation state a "digital insider presence" on the IMF.

Hackers broke into Sony’s computer networks and accessed the information of more than one million customers.

A virus targeting smart phones in China running Google’s Android operating system may represent the most sophisticated bug to target mobile devices.
