Overview

Alias:

Adware/Apropos [Panda]

Category:

Dialer: Software that dials a phone number. Some dialers connect to local Internet Service Providers and are beneficial as configured. Others connect to toll numbers without user awareness or permission.

Backdoor: A secret or undocumented means of getting into a computer system, or software that uses such a means to penetrate a system. Some software has a backdoor placed by the programmer to allow them to gain access to troubleshoot or change the program. Software that is classified as a "backdoor" is designed to exploit a vulnerability in a system, and open it to future access by an attacker.

Downloader: A program designed to retrieve and install additional files, when run. Most will be configured to retrieve from a designated web or FTP site.

Exploit: A way of breaking into a system. An exploit takes advantage of a weakness in a system in order to hack it. Exploits are the root of the hacker culture. Hackers gain fame by discovering an exploit. Others gain fame by writing scripts for it. Legions of script-kiddies apply the exploit to millions of systems, whether it makes sense or not. Since people make the same mistakes over-and-over, exploits for very different systems start to look very much like each other. Most exploits can be classified under major categories: buffer overflow, directory climbing, defaults, Denial of Service.

Flooder: A program that overloads a connection by any mechanism, such as fast pinging, causing a DoS attack.

Key Logger: (Keystroke Logger). A program that runs in the background, recording all the keystrokes. Once keystrokes are logged, they are hidden in the machine for later retrieval, or shipped raw to the attacker. The attacker then peruses them carefully in the hopes of either finding passwords, or possibly other useful information that could be used to compromise the system or be used in a social engineering attack. For example, a key logger will reveal the contents of all e-mail composed by the user. Keylog programs are commonly included in rootkits and RATs (remote administration trojans).
