Web-hosting firm eUKHost has been hacked by Pakistani hacking team UrduHack, which appeared to have gained access to its billing system.
The company sent out an email to customers and announced on its website over the weekend that it had spotted the intrusion within the last 24 hours.
"We can confirm that an administrator level login was compromised and an IP address added to an allow list to allow a successful login," eUKHost said on Saturday morning.
"We are still investigating how this compromise occurred and we can't currently see any evidence of a database dump," the firm added.
eUKHost managing director John Strong told The Register that the hackers had not bothered to cover their tracks by deleting logs and the company had identified them as Pakistani group UrduHack.
The hackers gained entry via some "outdated software that wasn't shut down properly on the website", he added.
UrduHack was also responsible for compromising Israeli web hosting firm Galcomm, but it seems more interested in proving it can enter closed systems than in actually using the data it gains access to.
The group usually posts videos of its hacks on YouTube and posted the eUKHost video four weeks ago.
eUKHost said on Saturday that it was moving the billing system to a new server and changing the encryption algorithm for staff and customers.
"We have not noticed an increase in compromised accounts of clients and our initial research does seem to suggest the perpetrator wasn’t out to cause damage to our customers, but until we better understand the nature of this problem, we can not take anything for granted," the hosting firm said on Saturday.
eUKHost later confirmed that it hadn't found any risk to payment details such as credit card numbers during its investigation.
Strong said the move to the new servers had been completed by 8pm yesterday evening and said that eUKHost would be reporting the incident to the Information Commissioner's Office.
He also said that according to the logs, the hackers had only visited a few accounts, although the company wasn't ruling out the possibility that some logs had been deleted. ®
