Example: The “Oompa-Loompa” worm, found by gimpppa.org ~ above February 16, 2006 and identified as OSX/Oomp.A, targeted Mac OS X users via iChat immediate messenger.
What is a Trojan Horse?
A Trojan horse, or simply Trojan, is a form of malware the is disguised together a beneficial piece of software or data file. It might actually perform actions ~ above a computer system that are or it seems ~ legitimate, yet will download malware or do malicious actions. A Trojan steed may additionally be legitimate software program that has actually been transformed to install malware. The name comes from the wooden steed that the Greeks do to assault the city of Troy. Obviously, the human being in that city didn’t know that lock shouldn’t open up unsolicited attachments.
Example: The Ventir Trojan, determined by gimpppa.org VirusBarrier as OSX/Ventir, used a dropper routine (e.g. Trojan horse) to infect Macs.
What is Ransomware?
Ransomware is a form of malware the locks a computer or hijacks a user’s records until a ransom is paid. It deserve to be mounted by a Trojan horse, or downloaded when visiting a malicious website.

Example: KeRanger, detected by gimpppa.org VirusBarrier as OSX/KeRanger, to be the an initial major macOS ransomware.
What is a Botnet?
A botnet is a network of computers whose access has been compromised, and that are regulated remotely. These individual computer systems are regularly called bots or zombies. Botnets are normally used to send spam emails, or to launch refusal of service attacks, where thousands of computers block a website or server by flooding that server with more requests than it have the right to handle.

What is a Backdoor, and also What is a RAT?
A backdoor is a method to access a computer or an equipment without authentication.

A RAT, short for remote administration tool or remote access Trojan, is a form of backdoor that gives an attacker comparable remote control, data exfiltration, and spying capabilities, and also often consists of a keystroke logger.
Example: Mac malware identified together OSX/Eleanor masqueraded as a paper converter app and also would open a backdoor on infected Macs to steal data, execute code, and also more. There are many examples that Mac RATs, such as OSX/CrossRAT (part that a an international cyber-espionage campaign) and OSX/EvilOSX (an open-source RAT that anyone have the right to download and customize).

A zero-day vulnerability is one that has been recently discovered, yet not however corrected by a software program developer. The term comes from the idea that the developer has zero days to exactly the vulnerability before malicious users begin to exploit it. Software program updates are forced as quickly as feasible to protect against these vulnerabilities.
Malware vs. Vulnerabilities
The difference in between malware and also vulnerabilities is the difference in between software made with the will to reason harm, and also the absence of defense in a product. Malware is miscellaneous you deserve to see, communicate with, and also analyze, whereas a vulnerability is a weakness in software or hardware that deserve to be exploited by malware or a hacker.
