NEW YORK—Anonymous, a collective of hackers, claimed last week that as part of a cyberattack on HSBC it was able to stel information on tens of thousands of credit unions. HSBC, however, issued a statement late last week saying its data had not been breached.
The denial-of-service attack did slow access to the $2.7-trillion HSBC's website for customers, some of whom were unable to log into accounts.
Anonymous said in a tweet on Friday that it had managed to "log 20,000 debit card details."
"Were debating whether to release them or not, HSBC knows debit details were intercepted, They probz won't admit it tho," the group said.
Anonymous, however, is not the only group claiming responsibility for the attack. Another group that calls itself Izz ad-Din Al Qassam Group, which has claimed responsibility for recent cyberattacks on at least nine other banks, also took responsibility for the assault on HSBC. The Al Qassam Group has vowed to attack banks in retaliation for an American-made, anti-Islam film.
Meanwhile, Anonymous also has identified other banks the group says it will target as part of its cyber offensive. "RBS, Lloyds TSB and Barclays are next," the group said in a tweet.
