Last Thursday, the main member-facing Patelco website was down for around five hours, said Patelco CEO Ken Burns in an interview Tuesday.
“It appears to have been DDoS,” said Burns, referring to the technique of bringing a web host down by flooding it with meaningless information and pointless requests.
As for who launched the attack, the $3.8 billion Patelco (headquartered in Pleasanton, Calif.) on Tuesday was claimed as a victim in a long list of victimized financial institutions posted to the web by the Izz ad-Din al-Qassam Cyber Fighters, the group that has been behind the current wave of DDoS attacks.
Patelco is the second credit union named as a victim, Also last Thursday, the $1.5 billion University Federal Credit Union in Austin, Texas, suffered an outage that a spokesperson said lasted two and one half hours.
[...] in a proof of the sophistication of the attack, the attackers quickly realized what Patelco IT had done and they managed to track down where the traffic had been redirected. They aimed their data barrage there, again crippling Patelco’s servers
