Think W3 Limited was hacked in December 2012 in an attack that relied on what the ICO described as "insecure" coding on the website of its subsidiary business, Essential Travel Ltd. The unidentified hacker behind the attack siphoned off a total of 1,163,996 credit and debit card records (431K current and 733K expired).

"Cardholder details had not been deleted since 2006 and there had been no security checks or reviews since the system had been installed," according to a subsequent investigation into the incident by data privacy watchdogs at the Information Commissioner’s Office (ICO). Think W3 was found guilty of a "serious" breach of the DPA.
