JPMorgan Chase's consumer website was knocked offline last night, reportedly after being hit by a denial of service cyber attack.
The site was unavailable to some users on Tuesday evening. Widespread reports have since emerged claiming the outage was the result of a denial of service attack by an unnamed hacker group.
At the time of publishing JPMorgan Chase had not responded to V3's request for comment on the outage.
JPMorgan Chase is one of many financial institutions to be hit by cyber attacks over the last year.
Earlier this week the Reserve Bank of Australia (RBA) confirmed its networks were hit by a number of cyber attacks in 2011 but said no data has been lost during the raids.
Elsewhere numerous other banks were hit by distributed denial of service attacks at the end of 2012. Victims included big names like US bank Wells Fargo, the Bank of America and Citigroup.
The attacks led the US Financial Services Information Sharing and Analysis Center (FS-ISAC) upgraded its Cyber Threat Advisory status from Elevated to High.
Since the campaign began a hacktivist group has come forward claiming responsibility for the attacks.
The group initially took credit for the attacks in a Pastebin post midway through 2012, claiming the attacks were designed to protest the portrayal of Muslims in the "Innocence of Muslims," YouTube movie trailers.
The group resurfaced earlier this month announcing plans to launch another series of distributed denial of service (DDoS) attacks against financial institutions in the US.
While the credit for the attacks is not concrete it underlines the growing threat facing financial organisations across the world.
