MADISON, Wis. (4/2/13)--American Express Co. is the most recent financial company to be victimized by a distributed denial of service (DDoS) attack.
The cyberattack on Thursday knocked Amex's website offline for two hours, and 43 customers reported they were unable to access their accounts (Bank Technology News March 29).
There was no evidence that customers' data were compromised, Amelia Woltering, AmEx company spokeswoman, told Bank Technology.
In the past week, similar DDoS attacks impacted Wells Fargo and TD Bank. That is part of a wave of disruptions that began in September, disrupting many of the websites of the biggest U.S. financial institutions, the publication said.
Wells Fargo was hit with a DDoS attack March 26 that prevented some customers--184 reports in a 24-hour period--from accessing their online accounts (American Banker March 26).
JPMorgan Chase and BB&T had recently sustained similar attacks, the Banker said. JPMorgan Chase Monday told its customers through Twitter that it was "experiencing intermittent issues," and advised them to use the bank's mobile service while it worked to resolve the issues (American Banker April1).
The al-Qassam Cyber Fighters hacktivist group has claimed responsibility for many of the attacks against banks and two credit unions.
Also, Spamhaus, an anti-spam service, was disrupted Thursday with the biggest DDoS ever seen, according to several security firms (computerworld.com March 27).
Computerworld noted the attacks, which have been going on since March 19, allegedly started after Dutch hosting provider Cyberbunker was placed on Geneva-based Spamhaus' global blacklist, according to a New York Times report. Cyberbunker is known for being willing to host nearly any website--except those associated with child pornography or terrorism, Computerworld said.
