The Phishing Grounds

On August 15, 2013, Brian Krebs featured a screen shot of a fake Outlook webmail login page used by the Syrian Electronic Army in a phishing attack against the Washington Post. If you look carefully at the location bar, you will note that the domain used in the phishing attack is ‘webmail.washpost.site88.net’.

The domain ‘site88.net’ is actually part of a suite of domains belonging to 000webhost.com. 000webhost.com bills itself as a provider of “top class free web hosting services.” Just like free services offered by changeip.com, 000webhost.com has also become a haven for miscreants.

Looking through all the subdomains that are in use at 000webhost.com, we can find many suspicious looking domain names. The following subdomains have shown up since the beginning of September 2013 in passive DNS. Facebook, Yahoo’s Ymail, Google’s Gmail, Paypal, Twitter, and Microsoft Hotmail are all targets for abuse.

Cisco TRAC recommends that all organizations pay extra close attention to any traffic destined for free services such as this. There little chance that anything of value would be missed if these 000webhost domains were blocked wholesale by an enterprise.
