Sometimes things are burning. It's very hard to avoid that fact. It can be a lot of things that goes on fire: houses, people, bushes First it's melting, dripping down the chimneys faster than St. Claus, and when it's even warmer it burst in flames Every time a user typed cat filename , the command rm filename would be executed instead.

To redirect one command to another command, type the following:. In the instance of a system administrator running a tool such as Tripwire to check the status of important system binaries, the ered command would render the tool useless. This is because Knark catches the system call specifying the executable at the kernel level, and when the system call is executed, it runs the destination executable instead. Therefore, Tripwire would not detect this hacker activity. This tool is executed with the following command:.

Therefore, these types of packets usually make it through a security architecture and the command is executed on the victim machine. Hiding Knark. Because all the loaded kernels are displayed when the lsmod command is issued, Knark will be included in that list.

Of course, we could rename knark. After Knark has been installed, you would type the following command:. This command will return with an error, which is expected and accepted. Now, typing the lsmod command does not produce the knark. After modhide has been loaded, Knark can be uninstalled only by rebooting the victim machine.

A simple network contains a Windows 98 machine and a Linux server. The network is guarded with a standard stateful packet-filtering firewall with few filtering rules inbound. In fact, the administrator of the firewall was so lazy that he allowed the same ports inbound for the entire subnet. Everyone knows how much of a hassle it is to submit the proper paperwork to open and close ports in a large organization!

Outbound from this network all traffic is allowed, which is a typical configuration in modern times. No firewalls exist between each of the victim machines in the subnet, so any and all traffic will be transmitted between them. Machine Type. The goal is to control this network remotely after it has already been compromised. The following paragraphs discuss several scenarios that an attacker can use to gain access to these systems. The hacker changes the port to TCP port 80, binds it to an innocuous program, and dangles it in front of the administrator in an attractive manner in hopes that the admin will run the trojaned program.

After the administrator runs this program, which installs VNC and adds the appropriate registry values, the hacker will be able to connect to his Windows workstation through the misconfigured firewall. The attacker can gain access to the administrator's Windows workstation if the administrator runs this program on the victim machine. Therefore, the attacker would want to dangle this program, attached to an attractive innocuous program, in front of the administrator in hopes it will be executed.

Once it has been executed, the attacker has gained access to the network. If the attacker can get the administrator to install this on his machine by binding it with an attractive program, easy access is gained into the network.
