Wells Fargo & Co (NYSE:WFC) has been the victim of another cyber-attack, possibly from the Islamic terrorist group Izz ad-Din al-Qassam. JPMorgan Chase & Co. (NYSE:JPM) fell victim to a similar attack allegedly from the same group earlier this month.

Fox Business reported that the Wells Fargo & Co (NYSE:WFC)’s website was hit on Tuesday and affected many customers. A spokesperson for the bank told CNET that they detected an “unusually high volume of Web site traffic,” which they believed was a denial of service cyber-attack.

The bank said most customers were not affected, and customer information was not accessed. It also said bank branches and ATMs were not affected by the attack. The Islamic militant group Izz ad-Din al-Qassam apparently posted a warning about the attack on Pastebin on Tuesday, just as it did in the attack earlier this month on JPMorgan Chase & co. (NYSE:JPM).

Like the earlier posting, Tuesday’s post said the group would also target many other major banks in the U.S., including Citigroup Inc. (NYSE:C), PNC Financial Services (NYSE:PNC), U.S. Bancorp (NYSE:USB), BB&T Corporation (NYSE:BBT) and Fifth Third Bancorp (NASDAQ:FITB). The posting also said the attacks are a protest against the YouTube video called “Innocence of Muslims,” which has raised the ire of those who see it as being anti-Islamic.

Wells Fargo & Co (NYSE:WFC) and several other major U.S. banks were also hit by cyber-attacks in September, and the group also claimed that it was responsible for them and said it would keep launching the attacks until the video it is protesting is taken off of YouTube.
