British Airways e-ticket malware attack launched via email

If you have received an unexpected email, claiming to come from British Airways, about an upcoming flight that you haven’t booked – please be on your guard.

Online criminals are attempting to infect innocent users’ computers with a variant of the malicious Win32/Spy.Zbot.AAU trojan, by disguising their attack as an e-ticket from the airline.

To maximise the potential number of victims, the attackers have spammed out messages widely from compromised computers.

Malware spread via bogus British Airways email

Here’s an example of what part of a typical malicious email spread in this spammed-out campaign looks like:

From: British Airways [mailto:BA.CustSrvcs@email.ba.com]
Subject: Your Order #70391830 / 25 feb 2014

Dear Customer,

This is a confirmation that your order has been successfully processed.

Booking reference: 9C1PWF
DEPARTURE DATE & TIME / FEB 28, 2014, 11:30 AM
DEPARTING / LONDON
TOTAL PRICE / 650 GBP

The flight number and the seat number can be located in the lower part of the ticket.

An electronic copy of the ticket can be downloaded from our website :

Of course, although the email claims to come from British Airways – it is nothing of the sort.

In a classic example of social engineering, criminals are hoping that email recipients will worry that their credit card has been fraudulently used to purchase an air ticket, and click on links inside the email to find out more.

However, if users download the supposed e-ticket and launch its contents, they will be infecting themselves with a trojan horse that can spy on their computer activity and give malicious hackers third-party access to their data.

ESET antivirus products detect the malware as a variant of Win32/Spy.Zbot.AAU.

ESET intercepting malware spread via bogus British Airways email

Users of other anti-virus products would be wise to check that their systems are updated, and protected against the threat.

In this case, the malware has been spread via malicious links after cybercriminals forged email headers to make their messages look like they really came from British Airways’s customer service department. But it’s equally possible for attackers to spread their malware via email attachments, or for other disguises to be deployed if those behind the spam blitz believe that they have a greater chance of success.

Remember to always be suspicious of clicking on links in unsolicited emails, and the social engineering tricks that are frequently used to lure computer users into making unwise decisions.

    Thank you for this – I have just had a message of the same kind and your post is very helpful. I’ve forwarded my message to phishing@email.ba.com and would advise others reading this who have had such a message to do the same. My email even had the same flight ref as your example above.

      Glad to have helped Helen.

      Yes, forwarding phishing emails like this to special addresses set up by organisations definitely helps. Well done for being alert and not falling for it!

    I figured it was suspect that I’d supposedly booked a flight with them yet they referred to me as “Customer” instead of my name. If you hover your mouse over the first link, you see that the URL is actually different from what the text says. They do this in the same way that you can make “click here” into a hyperlink. Warn your parents, I guess.

    Had this arrive in my work inbox on Monday. Was immediately suspicious as I haven’t booked any flights, though didn’t think it was from fraudulent card use.
    In my email the second link was a genuine link to the BA site, but hoveing my mouse over the first revealed it to be of another origin and contained a .zip file.
    This is certainly one of the cleverer phishing mails I have received and I took a screen grab of it, to use as a reminder and warning to my colleagues at work, about the dangers of unsolicited emails.
