According to an update on its website, HSBC repaired all of its websites globally to full availability as of 3:00am UK time.
The international bank strained that no customer information was compromised by the attack in a statement they posted on their website posted on its website:
On 18 October 2012 HSBC servers came under a denial of service attack which affected a number of HSBC websites around the world.
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 cooperate with other organisations that have been similarly affected by such criminal acts.
We apologise for any inconvenience caused to our customers throughout the world.
The bank’s site was done for no more than a day. Attacks like these effect companies greatly, as their customers are effected as well.
Most DDoS attacks occur by pointing a botnet (network of infected PCs) to a specific IP or domain name. You could be helping these criminals, so scan your system today.
There are many payed and free virus scanners, ZeroSecurity suggests Malwarebytes, as it’s free and effective.
