Via Pittsburgh Post-Gazette:

A protest group that claimed responsibility for a wave of digital attacks on big U.S. banks in the fall — including Pittsburgh-based PNC Bank — apparently has PNC in its crosshairs again.

The al-Qassam Cyber Fighters said in an Internet posting that the group plans a second round of attacks this week on PNC and four other banks — JPMorgan Chase, Bank of America, U.S. Bank and SunTrust.

A spokeswoman for PNC was not immediately available for comment.

In September, PNC’s online banking operations were disrupted for a couple of days by the so-called denial of service attacks, which flood websites with communications requests.

In the latest phase, “the wideness and the number of attacks will increase explicitly,” the protest group said in a message posted on a website called Pastebin.

The group has said the attacks would continue until a YouTube video insulting the Islamic prophet Muhammad was removed from the Internet.
