Blind Drop – A drop that is well hidden and is designed to run while unattended, until an attacker comes to collect the data. In the case of remote access Trojans, can also refer to file hidden locally.
Bot – A computer infected with software that allows it to be controlled by a remote attacker. Also used to refer to the malware itself which allows that control.
Carder – Someone who trades in stolen credit card and cardholder data.
Downloader – A small piece of code, usually a single instruction, used in the payload of an exploit to silently fetch a malicious EXE file from the attacker's server.
Drop – A clandestine computer or service [such as e-mail account] that collects data stolen by a Trojan.
Dump – As a noun, used interchangeably with “drop.” As a verb it means to transfer data onto a machine for analysis, or to discard an exe after reverse engineering.
exe – A Windows executable program. In a malware attack, the "exe" refers to the malicious progam which infects the victim's PC.
Exploit – Code used to take advantage vulnerabilities in software code and configuration, usually to install malware.
Form-grabber – A program that steals information submitted by a user to a web site. (Originally forms were the only way to submit user input to a web server, but now the meaning has changed to encompass any HTTP communication using a POST request.)
Gozi – One of a family of Trojans written by Russian RATs known as the HangUp Team, used in a string of attacks orchestrated by a group known as 76service.
iFramer – A person who places a malicious IFRAME (in-line frame) tag into web pages, usually on compromised web sites, and then charges malware developers for access to those iFrames as a distribution method for Trojans.
Keylogger – A program that logs user input from the keyboard, usually without the user's knowledge or permission.
Malware – Any executable code that uses a computer in a way not authorized by it's owner. Includes Trojans that install backdoors, spyware, bot clients, keyloggers, worms, viruses, or other malicious code.
Packer – A tool used to compress and scramble an EXE file. Used to hide the malicious nature of malware and thwart analysis by researchers.
Padonki – A kind of Russian hacker slang in which words, often obscene ones, are purposefully misspelled or bastardized.

Redirect – A feature of HTTP used to automatically forward someone from one web site to another. In the case of malware, redirects are done invisibly, sometimes inside iFrames.
Rootkit – Code that plugs into and changes the low-level functions of an operating system. Used by malware to hide itself from users and even the operating system itself.
Torpig – A relatively new family of Trojans representing the latest in malware capabilities, including the ability to hide itself and provide backdoor access for installing other configurations, components, or even other Trojans.
Trojan – A program that attempts to hide its malicious code by masquerading as an innocuous program most commonly through the use of a "packer."
Variant – Malware that is produced from the same code base (or "family") as a previous version but is different enough to require new signatures for detection by anti-virus and anti-malware products.
VXer – Originally, a virus writer. Now refers to anyone involved in the production or use of malware.
