Cyber criminals have instigated a fake email campaign targeting millions of internet users with malware-laden e-ticket receipts, claiming to be for British Airways flights.
Security firm Webroot reported discovering the new bogus email campaign on Monday, warning that the attack has already sent out millions of the bogus messages.
The fake email infects computers with malware via a malicious attachment.
"Cyber criminals are currently mass mailing millions of emails in an attempt to trick British Airways customers into executing the malicious attachment found in the 'spamvertised' emails," wrote Webroot researcher Dancho Danchev.
"Upon execution, the malware opens a backdoor on the infected host, allowing the cybercriminals behind the campaign to gain complete control over the infected host."
At the time of publishing British Airways had not responded to V3's request for comment on the spam campaign.
The attack is one of many malicious email campaigns currently running across Europe. Earlier in October, a similar spam campaign was caught targeting Skype users.
The campaign saw the criminals attempt to spread malware using an infected link sent over Skype's instant messaging service.
The news follows reports of a general boom in spam levels within the UK.
Prior to Webroot's warning, competitor Sophos issued its own spam research paper revealing that UK spam levels have risen again, causing the country to re-enter the top 12 countries responsible for spam.
