Members of British Airways Executive Club are noticing suspicious activities for their accounts. Members of BA Executive Club noticed that their accounts were mysteriously emptied of their Avios reward points. British Airways said that members were sharing same credentials on another web service that could have been hacked. This means that hackers used credentials available in the underground to gain access to the accounts belonging to BA members of Executive Club. BA has now locked down its online account to protect it from further access. Security expert Graham Cluley said that there is also the risk of further phishing attacks.”]
