Malvertising Found on Dating Site Match[dot]com

In an attack similar to the onethat happened last month on PlentyOfFish, the UK version ofonline dating site was caught serving malvertising.

Both companies are actually related since the Match Group bought out last summer. This latest malvertising incident is the work of the same gang using Google shortened URLs leading to the Angler exploit kit.

Themalvertising goes through a shortened URL (already blacklisted) that loads the Angler exploit kit:


Angler EK is known to serve the Bedep ad fraud Trojan as well as CryptoWall ransomware.

The cost per thousand impressions (CPM) for the booby trapped ad was only 36 cents, which is nothing compared to how much infected computers canbring in terms of revenues. For instance, CryptoWall demands $500 per victim.

We alerted and the related advertisers but the malvertising campaign is still ongoing via other routes.
