Some customers of Wells Fargo (NYSE:WFC) were unable to access their accounts on Tuesday.
The bank’s online operations were disrupted by hackers, who launched a denial-of-service attack on its website. The attacks, which feature a barrage of access attempts, overwhelming a website’s ability to handle them all, does not compromise secure data, the Los Angeles Times notes.
Izz ad-Din al-Qassam Cyber Fighters, a purported Islamic hacker group, claims that it is behind the attacks. The group is demanding the removal of a video that they say slanders the Prophet Muhammad from Google‘s (NASDAQ:GOOG) YouTube. The same group is claimed responsibility for similar attacks on the websites of JPMorgan Chase (NYSE:JPM) and Bank of America (NYSE:BAC) last year.
Wells Fargo said that the attacks were intermittent and that most customers were able to access their accounts. The bank issued an apology for any inconvenience encountered by customers.
Shares of Wells Fargo dipped fractionally in Wednesday midday trading.
