The hotel-chain Travelodge today released a letter to its customers revealing that a recent hack on its networks may have granted hackers access to their credit card details.
Travelodge went on to warn all customers to be wary of any future spam emails. The letter sent to its customers read:
"Our main priority is to ensure the security of our customers' data, which is why I wanted to make you aware that a small number of you may have received a spam email via the email address you have registered with us.
"Please be assured, we have not sold any customer data and no financial information has been compromised.
"All financial data (including credit card information) is compliant with current best practice standards and is audited to PCI (Payment Card Industry) requirements. The safety and security of your personal information is of the utmost importance to us and as a result we are currently conducting a comprehensive investigation into this issue."
Travelodge went on to confirm that it had informed the Information Commissioner's Office of the attack.
The news comes as hacking collective LulzSec and Anonymous' Operation Anti-Security hacking campaign continues to ravage the world, today claiming Arizona law enforcement as its latest victim.
While information regarding the attack is limited, it is unlikely that the attack is a part of the two hacker collectives joint campaign. Neither group has claimed responsibility and the nature of the attack on Travelodge is atypical of both LulzSec and Anonymous behaviour.
Operation Anti-Security was announced earlier this month as a combined effort by LulzSec and Anonymous. Both groups clearly outlined the campaigns cause as to protest internet censorship. A statement released by LulzSec also clarified that the campaign would direct its efforts to targeting governments and institutions.
Travelodge is yet to release further information about the exact nature of the attack.
