Sadly, Cligs fell victim to an online attack this weekend that changed about 2.2 million shortened web addresses so that clicking on them brought unsuspecting Twitter and Web users to my latest sOCial Sunday post.

After a few tweets voicing my concern to Cligs' @cligs, I spoke with Pierre Far, creator of Cligs. He shared the following information:

• The security hole that the hacker exploited has been patched.
• New cligs are not vulnerable to the hack.
• The cligs edit function that may have led to the issue has been temporarily disabled.
• Affected URLs are being corrected, and the restoration is expected to be completed over the next few days
• Cligs' Far is keeping users updated about the glitch in a post on the Cligs blog.

Update (2:50 p.m. June 16): Cligs confirms that 2,188,978 URLs were changed in the attack. Although 93% of those addresses will be restored in the next few days, 161,232 URLs were not backed up. The 2,268 registered users who created 41% of those addresses will be able to edit them after the restoration. The remaining 95,123 shortened URLs, created by anonymous users, will be changed to point to the Cligs Web site. More details have been posted on the Cligs blog.
