German internet users should be on their guard today, after malware was widely spammed out posing as a flight confirmation from Lufthansa.

Subject: Flugdetails & Reiseinformationen
Attached file: Flugscheindetails.zip

Falls Sie diese Reiseinformation nicht oder nur teilweise lesen konnen, offnen Sie bitte die angehangte PDF-Version. Bitte antworten Sie nicht auf diese E-Mail. Direkt-Antworten an den Absender konnen nicht bearbeitet werden. Um mit Lufthansa in Kontakt zu treten, rufen Sie bitte den Hilfe & Kontakt-Bereich auf www.lufthansa.com auf.

Flugscheindetails & Reiseinformationen in der beigefugten Datei

* Den Passenger Receipt (Rechnungsbeleg) erhalten Sie durch einen Klick auf die Flugscheinnummer bis 30 Tage nach Reisebeginn.

Of course, the emails don’t really come from Lufthansa – but it’s likely that some internet users will have been duped into clicking on the attachment, even if they aren’t planning to travel anywhere, our of sheer curiousity.

The attached ZIP file contains a file called Flugsheindetails.PDF.exe, clearly named in an attempt to trick the unwary into believing it is a PDF.
