Iran said to be responsible for cyberattacks on U.S. banks

The massive wave of DDoS attacks that hit U.S. banks recently was thought to have been done by a fringe hacker group, however government officials now believe it was the work of Iran.

Several U.S. banks were hit with online attacks over the past few months, but it’s been unclear who was responsible. Now, government officials and security researchers are saying Iran was waging these cyberattacks, according to a report by theNew York Times.

“There is no doubt within the U.S. government that Iran is behind these attacks,” James A. Lewis, a former official in the State and Commerce departments and a computer security expert at the Center for Strategic and International Studies in Washington, told the Times.

The attacks were aimed at several major banks, including Wells Fargo, J.P. Morgan Chase, Bank of America, Citigroup, HSBC, and others. They involved inundating the banks’ Web siteswith bogus traffic, known as distributed denial-of-service attacks.

“The amount of bandwidth that is flooding the websites is very large, much larger than in other attacks, and in a sense unprecedented,” chief executive of private security firm CrowdStrike Dmitri Alperovitch told the Wall Street Journal in September.

Apparently, it was the huge amount of traffic, along with the know-how to carry out these types of attacks, that convinced U.S. government officials that attacks were coming from Iran. These officials, however, have not provided any technical evidence to back up their claims.

While the cyberattacks were an inconvenience to both the banks and their customers, no private data or information was known to be stolen. According to the New York Times, security experts said this is further proof that the DDoS attacks were state-sponsored.

An unknown group called the “cyber fighters of Izz ad-din Al qassam” has claimed responsibility for the attacks – saying that it was retaliating for the release of the controversial video posted to YouTube that mocked the Prophet Mohammad. The group has warned that the attacks would continue until the video was removed from “the Internet.” However, according to the New York Times, officials now believe that Izz ad-din Al qassam was actually a cover for Iran.
