Bonn - Internet users are currently being warned too look out for e-mail messages claiming to be from package courier UPS. The messages, delivered in English and in German, actually originate from hackers, the German Federal Agency for Security in Information Technology (BSI) reported recently.

The messages tell the recipient that a package could not be delivered due to a non-existent address. The message then encourages the user to click on an e-mail attachment to check the delivery slip data; anyone who does so allows a Trojan virus to sneak onto their computer.

The subject line of the fake e-mail messages usually contains something like "Your UPS package," followed by a string of letters and numbers. (dpa)
