Hacker can see with the expertise & fix software on the computer, and then usually in openly published on the Internet for the system to be better. Sialnya, few people take the bad information to evil - they are usually called cracker. Sialnya, few people take the bad information to evil - they are usually called cracker.

Well, the young are generally cracker cracking do to improve / use of resources in the network for its own sake.

See the weaknesses with the system program mejalankan scanner. See the Weaknesses with the system program mejalankan scanner. After obtaining root access, cracker akan install back door (backdoor) and close all existing general weakness.

Separation of Intranet and Internet network is generally carried out using the technique / software firewall and proxy server.

In addition, by using the agressive-SNMP scanner & programs that force the SNMP community string can change the router into a bridge (bridge), which can then be used for the stepping stone for entry into the company's internal network (Intranet).

Cracker protected so that during the attack, technique cloacking (masquerade) is done with the jump from the previous machine has been compromised (ditaklukan) through a telnet program or RSH.

In the intermediary machine that uses Windows attack can be done with the jump from the Wingate. In the intermediary machine that uses Windows attack can be done with the jump from the Wingate. In addition, the jump can be done through the proxy device configuration is less good. In addition, the jump can be done through the proxy device configuration is less good.

After a successful jump and enter the other systems, cracker like to probing of the network and collect the information necessary. After a successful jump and enter the other systems, cracker like to probing of the network and collect the necessary information. This is done in different ways, for example, (1) using the nslookup command to run the 'ls', (2) view HTML files on your webserver to identify other machines, (3) to see various documents on the FTP server, (4) connecting the self to mail server and use the command 'expn', and (5) mem-finger user machines in the other external.

The next step, cracker akan identify which network components trusted by the system any. The next step, cracker akan Identify which network components trusted by the system any. Network components are the server administrator and machines that are usually in the most secure in the network.

Start with a check & export NFS access to a variety of critical directory such as / usr / bin, / etc and / home.

Exploit weaknesses engine through the Common Gateway Interface (CGI), with access to the file / etc / hosts.allow.

Next cracker network components need to identify the weak and the taklukan. Next cracker network components need to Identify the weak and the taklukan. Cracker can use the program in Linux like ADMhack, mscan, nmap and many other small scanner. Cracker can use the program in Linux like ADMhack, mscan, nmap and many other small scanner. Programs such as' ps' & 'netstat' in a trojan (horse TROYA remember the story? Classic story in ancient Greece) to hide the scanning process.

For the cracker can use the advanced quite aggressive scanning for SNMP-men-scan equipment with SNMP. For the cracker can use the advanced quite aggressive scanning for SNMP-men-scan equipment with SNMP.

After a successful cracker identify network components that can be weak and in taklukan, the cracker will run the program to the daemon program menaklukan weak in the server. After a successful cracker Identify the network components that can be weak and in taklukan, the cracker will run the program to the daemon program menaklukan weak in the server. The program is a daemon program on the server is usually running behind the screen (as a daemon / Satan).

Menaklukan success of this program akan daemon allows a cracker to gain access as' root '(administrator in the server).

To remove the impression, a cracker is usually cleaning operation 'clean-up' operation with a variety of ways to clean the log file.

Rhosts in / usr / bin for easy access to the engine in RSH & taklukan through csh.

Then a cracker can use a machine that is already ditaklukan for their own interests, for example, take the sensitive information that should not dibacanya; mengcracking machine from another machine with a jump in taklukan; install a sniffer to see / record the various traffic / communication through; can even turn off the system / how to run the network with the command 'rm-rf / &'.

The latter will be very fatal consequences because the system will be destroyed at all, especially if all the software on the hard disk letakan.

Therefore, all machines & routers running mission critical should always check the security patch in & by the new software.

Backup to be very important especially on machines that run mission critical terselamatkan from the cracker ulah men-disable system with 'rm-rf / &'.

Hacking competition in motori by young people in the Linux User Group Indonesia (KPLI) of Semarang digerakan by children as young Kresno Aji (masaji@telkom.net), Agus Hartanto (hartx@writeme.com) & Lekso Budi Handoko (handoko @ riset.dinus.ac.id).
