Hacked: Who Else Is Using Your Computer?
A friend called me one day and asked if I would stop by to look at his computer. He said it was running abnormally slow and he had found something on his hard-drive he could not explain. I could almost guess what it was he found. Have I been hacked? You see, his computer had been hacked. Actually, in his case, his computer had been tagged. Similar to the image you see here. Tag, You're It! FTP Tagging - The most common purpose for someone to compromise your FTP server is for the storage and distribution of illegally obtained software and files. This could include cracked software, stolen movies, audio files, and pornography. Removing this type of contraband from your computer can be difficult, particularly if you are using a Microsoft Windows platform. Hackers use sophisticated scripts to create a maze of directory structures to house their wares on your computer. They may use a combination of names with spaces in them, and in some cases use extended characters (characters outside the normal alpha-numeric range). Deleting these directories through normal means may be difficult, if not impossible, for the average user. Many people wind up wiping their system and re-installing it, and that is if they're lucky enough to find out their system has been compromised. The above is a perfect example of why the statement, "I'm not worried about being hacked. What do I have that a hacker would want?" is not a good position to take. The fact is, you do have something they want, your computers resources. Why should a hacker store tons of illegally obtained files on their systems when they can use yours. The Good, The Bad, And The Ugly The Good The Bad There are many exploits, backdoors, and Trojans that effect, or are contained in, the myriad of IRC clients on the Internet. Making sure you choose one that's relatively safe to use is not an easy task. As an example, take a look at this list of IRC safety and security info at irc.org. The Ugly Just Open The Door And Let Them InPeer-to-Peer File Sharing If you have anti-virus software installed (and up-to-date), you've undoubtedly received messages regarding viruses when downloading files from peer-to-peer services. These are not the only things you could be downloading. Many hackers imbed root-kits in files and distribute them using peer-to-peer file sharing. Root kits contain many types of tools used by hackers to gain control over computers. If the installation of the kit on your computer goes undetected and is successful, it's only a matter of time before your computer is completely compromised. I can't tell you how many times I've found company employees (and technical personnel) using peer-to-peer file sharing services. Any organization that permits this is putting itself at risk. And, the risk is much greater as compared to a single home computer because of the number of potential internal targets. Conclusion Don't make the assumption that you are not a target just because you don't think you have anything of interest on your computer. If our computer becomes unstable or dramatically decreases in performance, don't assume it's just a quirk or that it's time to upgrade. Make sure you have a software or hardware firewall in place to protect you from the Internet. Your firewall should be configured not to allow anonymous inbound access from the Internet. This is the default configuration for most firewalls, but you should make sure the one you are using is properly configured. Make sure you have adequate virus and spyware protection, and your pattern signatures are up-to-date. Many anti-virus applications work on a subscription basis. It's not uncommon to find out your subscription expired. If it is expired, your software may not protect you from new and emerging threats. And, do what ever you can to stay away from any type of Internet peer-to-peer file sharing service. No matter how safe the developer claims it is.
