“Ihre Rechnung N92480375″ Email Could Be a Trojan

WTF Are Trojans?

Remember that college class you took on Greek mythology?

Neither do I.

Trojans get their name from Greek mythology, though — a Trojan is software that acts like a Trojan horse. The same way that Trojan horse looked like a great gift to the Spartans — only it was stuffed full of soldiers — Trojans are software that appear harmless but are really designed to kill your computer.

Trojans often pretend to be a video codec you need to watch porn — really — , maybe a photo attached to email, or some sort of other harmless software. Once you open your gates to a Trojan though, it can spy on you, download more malware, or allow a hacker to do whatever he wants on your machine.

How “Ihre Rechnung N92480375″ Email and Trojans Might Infect You

• Websites: When you’re surfing the web, you won’t only get infected when you download some codecs or plugins. Sometimes all you have to do is visit a site and a Trojan secretly downloads itself onto your computer. Scary. Use a browser like Firefox to prevent this — it’s much more secure than Internet Explorer.
• Open ports: If you run any file-sharing applications — and I’m not just talking peer-to-peer music software — you risk opening up your system to infection. It can be as simple as leaving file sharing open on your instant message client. My rule of thumb is to close off every port. Set up a firewall, too, if you don’t already have one.
• Email: Some random person you don’t really remember just forwarded you some hot pictures? Don’t open them. Lots of Trojans are dolled up as harmless looking email attachments that take advantage of security holes in your mail client. Spam blocker software can help, but it’s better just not to open any attachments from people you don’t know.
