Hackers are generally lazy but intelligent, which means they don’t like doing something boring that they can program the computer to do for them instead. As a result, hackers have unleashed a variety of tools designed to make their lives easier (but their victims’ lives more miserable). Some of these tools include scanners (to find open ports on vulnerable computers), remote Trojan horse programs (to take over a computer through the Internet), and password crackers (designed to exhaustively try out different password combinations until they finds one that works). To see what types of tools hackers may use against you, browse through the following:


Released around 1995, AOHell  defined the standard for online harassment programs and quickly spawned numerous copycats for harassing other online services including CompuServe, Prodigy, and the Microsoft Network. Written in Visual Basic 3.0, AOHell was a relatively simple program that helped hackers send spoofed email, create phony credit card numbers for making fake AOL accounts, con AOL users out of passwords and credit card numbers, and send insulting messages to others in chat rooms.

AOHell, the first and original online harassment tool.
Although AOHell initially caused problems for America Online users, the program is now obsolete. Few hackers are currently developing AOHell copycat programs, preferring to channel their energy towards creating more sophisticated Internet hacking tools such as port scanners or harassment tools that cause chaos on IRC or in ICQ chat rooms.

BO2K – Back Orifice

With a name deliberately chosen to mock Microsoft’s Back Office program, Back Orifice caused a sensation when released in 1998 as one of the first remote access Trojan horse programs that could remotely control another computer over a phone line or through the Internet

Back Orifice 2000 is the latest incarnation of the popular and ground-breaking remote access Trojan horse.
Developed by a hacker group calling themselves the Cult of the Dead Cow, Back Orifice ( made headlines again in 1999 when it was released at DefCon 7.0 with improvements, including the option of adding plug-in programs written by others, and the complete C/C++ source code so that anyone could study and modify the program. Ironically when introduced at DefCon, the Back Orifice 2000 CD was infected by the Chernobyl (CIH) virus.

Although Back Orifice still poses a threat to computers, the buzz surrounding BO2K has faded. Still, the program has spawned numerous remote access copycats programs that have improved upon the original Back Orifice design, and despite its age, Back Orifice still remains a favorite tool for hackers to probe computers connected to cable or DSL modems.

Crack Whore

One of the new breed of website hacking programs, Crack Whore uses a brute force/dictionary attack against a website to find the password to a legitimate account . Since so many people use weak, easy to guess passwords, programs like Crack Whore are surprisingly successful far more often than they should be!!

Crack Whore probes a website for easily-guessed passwords to give a hacker access to a system.
Once hackers have access to a legitimate account, they can either modify web pages and other data directly or attempt to burrow through the system and either gain access to additional accounts or elevate the current account to get greater access to the rest of the computer hosting a particular website.
