US bank websites hackers use advanced botnets, various tools: researchers

The distributed denial-of-service (DDoS) attacks troubled users in accessing their websites

By CBR Staff Writer

The websites of major US banks, which faced repeated online banking disturbances, were hacked using advanced and diverse tools that hints at a coordinated campaign, according to security researchers.

The researchers also revealed that the hackers, supposed to be protesters in the Middle East, were well-informed regarding the protective mechanism used by the banks and must have spent quite some time to investigate the mechanism.

Several customers of the major US banks including Bank of America, JPMorgan Chase & Co, Wells Fargo, U.S. Bancorp and PNC Financial Services reported trouble in accessing their websites, due to the distributed denial-of-service (DDoS) attacks.

According to Reuters, the hackers deployed clusters of compromised inexpensive computers called botnets that comprised web servers that had been taken over, rather than simple personal computers.

The compromised servers were teamed with itsoknoproblembro and other DDoS equipments that enabled the hackers to set free network packets as per the UDP, TCP, HTTP, and HTTPS protocols.

Further, the banks’ routers, servers, and server applications-layers 3, 4, and 7 of the networking stack-with junk traffic were flooded.

The news agency also revealed that Cyber Fighters of Izz ad-din Al Qassam group have accepted that they were responsible for the recent bank attacks, as part of a protest against the anti-Islam video posted on YouTube and strengthened violent protests all through the Muslim world.
