British Airways (BA) has become the latest victim of a cyber attack, which reportedly compromised thousands of British Airways frequent-flyer accounts.

The airline company acknowledged the issue and highlighted that that the problem has affected only a small group of customers out of its millions of customers worldwide.

According to reports, BA does not know who hacked the system but the airline company believes that the attack could have been carried out by an automated computer programme that might have been looking for vulnerabilities in the company’s online security systems.

The airline company also highlighted that important personal information including bank details, names and addresses have not been accessed by any third party sources, with the company expecting to fix the system and resume operations soon.

The Press Association cited a BA spokesman as saying: "British Airways has become aware of some unauthorised activity in relation to a small number of frequent-flyer executive club accounts.

"This appears to have been the result of a third party using information obtained elsewhere on the internet, via an automated process, to try to gain access to some accounts.

"We are sorry for the concern and inconvenience this matter has caused and would like to reassure customers that we are taking this incident seriously and have taken a number of steps to lock down accounts so they can no longer be accessed."
