Hackers stole dozens of customer credit and debit card numbers after hacking into the computer system of Conor O'Neill's Irish Pub in Ann Arbor, Michigan, local news sources report.
According to the Detroit Free Press, banks investigating the fraudulent use of card numbers in Texas between April and June discovered Conor O'Neill's was a common charge on all the victims' bills, leading authorities to notify the pub. The bar's general manager, Caroline Kaganov, told ClickOnDetroit.com that victimized customers had also contacted the bar directly.
Ann Arbor police have said the hackers might be European, and AnnArbor.com quotes Sgt. Pat Hughes as saying the stolen card numbers were likely sold on the black market, not used by the hackers themselves.
Kaganov and the police have assured patrons computer security has been boosted at the pub to protect customer information.
Shadowy hacker groups like LulzSec and Anonymous have recently made headlines for infiltrating big businesses like Citigroup and government agencies such as the CIA. The Conor O'Neill's hack serves as a reminder that cyber criminals do not only attack high-profile targets.
