HSBC Suffers 'Large Scale' Cyber Attack
Banking giant HSBC has revealed some of its websites were subjected to a "large scale" cyber attack that disrupted its online services on Thursday, but assured its customers their data was not compromised.
In a statement, HSBC said its servers came under a "large scale denial of service attack" that affected a number of sites around the world, although it did not give further details as to the nature or whereabouts of the problem.
It said: "This denial of service attack did not affect any customer data, but did prevent customers using HSBC online services, including internet banking. We are taking appropriate action, working hard to restore service.
"We are pleased to say that some sites are now back up and running. We are cooperating with the relevant authorities and will co-operate with other organisations that have been similarly affected by such criminal acts."
The statement added: "We apologise for any inconvenience caused to our customers throughout the world."
It gave no indication as to who was thought to be behind the attack.
Later, HSBC reported that its sites were back up and running and thanked customers for their patience.
A denial of service attack typically involves sites being saturated with requests.
The Inquirer website reported that the Anonymous group†had claimed it was behind the incident.
It said a Twitter account called @Fawkessecurity had claimed it was responsible and had posted a statement to Pastebin.
This said: "As some of you may be aware HSBC bank suffered several DDoS attacks on the named sites in the past hours us.hsbc.com hsbc.co.uk hsbc.com hsbc.ca they were all brought down by #FawkesSecurity.
"The proof is all in our Twitter account, Targets, time and date :) @FawkesSecurity."
