A computer virus attacked thousands of Israeli Facebook subscribers days before a threatened mass cyber attack on Israeli websites.
More than 2,000 Israeli Facebook users clicked on the malicious link Wednesday; 14,500 users worldwide clicked on the link. Nearly 4,000 Israeli Facebook users also shared the link with their friends.
It was unclear exactly what the link does besides replicating itself on Facebook, according to reports.
The virus comes four days before a threatened cyber attack operation on Israeli websites by the hacker group Anonymous and other hacker groups.
Anonymous in an operation code named OpIsrael has threatened to "wipe Israel off the Internet" by targeting dozens of Israeli websites, including banks, credit card companies and government sites.
It is not believed that the Facebook virus is related to the planned cyber attack.
