list of common program used

Some hackers use telnet or HyperTerminal with an open port to leave messages on the server.

Hackers can use telnet, HyperTerminal and Remote Desktop which are ordinary Windows programs.

if u meant about softwares to hijack or duing a mil bombing or some others it depends there are many hackers softwares..so normally they sur on the telnet and they interect directly with servers so it is pretty easy o use that..and if you write few lines of commands normal for servers ..these can send you mails..with fake adresss or others...but if you want attack on som basis and so you are searching to avoid a precise xploit ther are many ne scanning or others depending from which attack you want do it and so it will help you to pursue your goal!!

One question for you, are you in the U.S? If you are there is a great chance you are gonna get caught unless you know what your doin. My Question to all mylotters is why do all want to invade on someone PC by hacking, there is a great chance your ISP will report you and get you in trouble. Anything done on the internet can always be backtracked to the source. Why go to Jail for something so pointless, just to get revenge or screw around. heres a great saying for everyone, "You might commit a crime 99 times succesfully but on the 100th time your gonna get caught"

well, m not a hacker, so i don't know what all tools a hacker muct be using but i think most of hackers are fake and they make their own hacking fake software with the help of visual basics, i am a student of computers and i know it's very easy to make a fake software using visual basics.
