UIN=14254931), Sexy Ori (he thinks he's the greatest hacker in the world and he says he has "great programs" and even one that gets your phone number by your IP... yeah, and I'm the tooth fairy. Go DoS his lil' ass - UIN=18404796), Giora (the biggest liar on earth. Claims he's a great hacker but he wouldn't prove it and says he's a close friend of the guys who invented ICQ. UIN=2213907), JP (the racist media-whore, founder of www.antionline.com. More info at www.attrition.org in the "High Slanders" section) and all the l33t-talking lamers from #rootworm, #hackphreak, #hack, #hp, #hyperlink, #dps, #netbus, #bo and all the other lame Undernet channels (ok, ok, not everyone who spends time in those channels is lame, but there is a high quantity of lamers out there. Try going to one of those channels and see how long it takes until someone asks "where can I get a free
shell account?" or "how do I hack Hotmail?").

ACID / AciD - Ansi Creators in Demand (a hacking group)
ACK - Acknowledged (first, a little about the TCP protocol. When you want to send something from one computer to another using TCP you need to establish a connection first. The sender first sends a packet with the SYN flag on. On this point, the receiver can decide if he wants that packet. If a firewall is blocking the way or there is no daemon on the specific port the packet will be denied and the receiver will reply with a packet with the RST flag on. However, if the receiver wishes to accept the connection, he will reply with both SYN and ACK on, and then the sender should reply with ACK, which means he's ready to send. This is good because that way there is a lot less packet loss, and when something goes wrong the receiver can ask the sender to send that packet again. On UDP, you can't make sure the packet will ever get to the receiver but everything goes a lot faster that way. This is why realplayer (www.real.com) uses UDP and this is why video and audio sometimes get a little smudged when using it)

Hackers Associated Online (HaO) is now accepting members!@!$ Pull out that dust covered winnuke, your copy of AOHell and UpYours; they will finally be put to use. Yes, you read correctly, HaO is accepting members. You will finally be just as er33rt and f33red as the true elites, move over I-L and #feed-the-goats, it is HaO; they take no prisoners! HaO was founded to "to create a safe arena for information exchange"; only if you join and get access to their members' section, that is. Quick! Send in your application now, because "Not everyone that applies will be accepted into the organization." But beware, they have hard questions and high requirements if you wish to be a member of this motley crew. You have to answer such brain boggling questions, such as, "What is a BIOS?", "Who wrote the 'Hacker's Manifesto'?", and "What command do you type to get a directory listing in Linux?" (I think they mean "folder"). Be a hax0r, be a man, and be part of HaO)

If root is stupid enough to SUID, say, some text editor that everyone has an X priviledge to, everyone can read system files and even the /etc/shadow file. A good example for an SUIDed program is su. When you type the command su user it asks you for that user's password and then relogs you as that user and gives you his permissions.
