Saw this one on Slashdot and thought some on here might be interested. Linux Break-In Challenge
Am I the only one that is too paranoid (or ethical) to do any of these? I'm always afraid that if I'm successful men in sunglasses and black suits will show up at my house...
There's nothing unethical about it, as far as I can see. But IMHO what self respecting hacker is going to give away his best kept secrets to root a box that has nothing on it, and then gets to recieve nothing for his troubles. I mean really, why would I go to the trouble of breaking in to a house that was built expressly for that purpose to get a handshake when I can break in to the house next door that a big plasma TV still inside the box?
Duh, george. Some people.
Because a TV is to hard to move out of the house without getting caught.
Any good thief knows that when you get in you go right for the silver, the jewelry, any computers, paintings, and if it's me, the medicine drawer.
And if you're a real dick like my friend, you steal the batteries out of the remote controls of everything int he house so they all have to get up to change the channel. You'd be shocked how long people go without batteries because they are to lazy to go to the store.
Hrmm.. this was brought up in my CISSP class by one of the students so while they were doing their quiz I decided to do some poking. Visit here for the details. These are my results so far:
Linuxense.com whois
Off of their website the IP is listed as http://202.88.234.250/ . The WHOIS below shows the server as being in India. The Placeholder page suggests they are using a default install of Debian with Apache 1.3.31 (404 error page shows this up). Navigate into the Icons directory (http://202.88.234.250/icons) shows the various icons but navigating beyond the root of the web server isn't possible at this point. Telnet to 25, 23, 21 proved useless but 22 brought up some details: SSH-2.0-OpenSSH_3.8.1p1 Debian 1:3.8.1p1-4.1Quote:

I think KorpDeath said it all. :D
I ran nmap just for the hell of it. One surprising thing is the sheer amount of ports apparently open. My first instinct was that these aren't even real services running but some kind of decoy. Thoughts?
Also, the webpage says there is no firewall in front of the box, but something appears to catching the scan (due to all the timing corrections done by nmap.) ...or am I way off about that?

I wonder if your nmap scan is reporting stuff from their network equipment in front of the box...that would explain all those 'ports' or 'services', depending on the scan flags used, etc.
I believe all I did was, nmap -sS -v -O -sV. TCP SYN, TCP/ICMP pings, with version and OS detection...
One way to find out is to telnet to each of those services. I know I can connected and get a response from all the open ports above except 25. That one closes connections (probably to avoid SMTP Open Relay issues but may mean Sendmail is still running).Quote:

Well ! ... I've got a password prompt when i tried an rlogin to the address. We too share the same ISP, asianet !. Maybe give them a call and try out some social engineering.
