Banking giant HSBC has been hit by a cyber attack that prevented its customers from accessing internet and mobile banking services for several hours.
The bank said that it has successfully defended against the "denial of service attack", where a website is overloaded with traffic in an attempt to force it to crash.
The bank has not revealed details on the number of people affected by the attack but ensured that the personal details of its customers have not been breached.
HSBC said that the services were fully up and running again, and is currently working with government-backed Computer Emergency Response Team, Cert-UK, to identify the attackers.
The latest attack comes less than a month after a systems failure of the bank prevented its customers from using its online and mobile services for almost two days.
