Web host Linode, s clash over credit card raid claim

Crooks claim they gained access to server hosting biz Linode's customer s and credit card s.

On Frid
ay, Linode said someone tried to compromise one of its clients' machines, but insisted no financially sensitive information was . Linode reset all account s as a precautionary msure. The virtual server provider stated:

Message from Linode administrators

Linode administrators have discovered and blocked suspicious activity on the Linode network. This activity apprs to have been a coordinated attempt to access the account of one of our customers. This customer is aware of this activity and we have determined its extent and impact. We have found no evidence that any Linode data of any other customer was accessed. In addition, we have found no evidence that payment information of any customer was accessed.

We have been advised that law enforcement officials are aware of the intrusion into this customer’s systems. We have implemented all appropriate msures to provide the maximum amount of protection to our customers. Out of an abundance of caution, however, we have decided to implement a Linode Manager reset. In so doing, we have immediately expired all current s. You will be prompted to crte a new the next time that you log into the Linode Manager. We also recommend changing your LISH s and, if applicable, reerating your API .

The infiltrators snked into the server via an insecure installation of web app maker ColdFusion, according to a transcript of the s' IRC chatter. "It's surprising that anyone is still running ColdFusion - that's like connecting a 98 box to the internet without a firewall," said "Ryan", a representative of the HTP black-hat crew that apparently slurped the data.

Ryan claimed Linode encrypted its customers' credit card information but "both the private and public were stored on the web server", implying that the cache could be encrypted.

Today Linode, which operates a cloud of Linux virtual servers, responded to these claims with an updated statement denying that customer credit card data was . It blamed a ColdFusion bug for allowing in the s:

Linode has come under attack from black hats before. Last yr Linode was by cyber-thieves who made off with a stash of bitcoins worth $71,000 after brking into the digital safety deposit boxes of eight of its customers. Linode promised to revamp its security procedures in the wake of the robbery.
