I decided to write about this today because one of our clients was a victim of this particular piece of malware. ‘BackDoor Agent’ is a malicious program that has affected around 500,000 people, worldwide. While that number is particularly low compared to many other viruses and malware, this one deserves special mention because it gives hackers the ability to remotely access your computer system.
Once the Hackers have access to your computer system they can transmit information, modify files and install other software that is likely unwanted. These types of programs are called a ‘Trojan Horse’. If you know anything about Greek mythology or maybe you have seen the movie Troy, you likely know the general premise behind the Trojan Horse. In Greek mythology, the Greeks constructed a huge wooden horse, hid men within it. The Greeks as a manner of subterfuge got into their boats and sailed away, leaving the Trojan Horse behind. The leaders of Troy thinking they have won, hauled the Trojan Horse inside the walls of Troy, where the armed men inside waited until night fall to attack.
In a similar way, Trojan Horse malware, are sent to you, usually through email (but not always), the computer user unsuspectingly opens the email with the attachment thinking something important has just arrive. However, they have just invited inside the firewall of their computer a Trojan Horse. These Trojan Horse’s sometime carry relatively harmless pieces of malware and sometime, they contain malware of a much greater threat. The greatest indicators of a Trojan Horse on your computer will be the degradation in computer performance and the appearance of unwanted programs that you don’t recall downloading.
If you think you are the victim of a Trojan Horse or more specifically a BackDoor Agent, it is crucial that you get the malicious application off your computer immediately – if you are not comfortable doing this yourself, please bring your computer in to us at GMF Computers and we will remove any viruses or malware present and make sure your computer is up to date with the latest virus definitions and windows updates.
