Webroot is cautioning users not to fall for spam emails posing as a notification from American Airlines stating that their ticket is all set and ready for download.
This spam campaign isn’t exactly new, although previous versions may have had malicious files attached directly to the email itself.
Here’s what the current variant looks like:
Your bought ticket is attached to the letter as a scan document.
To use your ticket you should Download It.
The embedded link will prompt users to download an executable, “Electronic Ticket.exe” that only 10/46 antivirus will identify as malware.
Dr. Web antivirus detects the threat as BackDoor.Kuluoz.4. Once it has infected your system, BackDoor.Kuluoz.4 will modify system files, inject itself into system processes and connect to a list of command & control servers.
