Yet Another DDoS Attack on US Banks: From JPMorgan Chase to SunTrust

Looks like it’s a bad time running for U.S. based financial institutions. Not much time has passed when five U.S.-based banks, U.S. Bancorp, JPMorgan Chase, Bank of America, PNC Financial Services Group, and SunTrust became a target of DDoS attacks. And now again, hacker group called Izz ad-Din al-Qassam Cyber Fighters warned it would launch a series of distributed denial of service (DDoS) attacks against these banks.
