1.2 a type of malware that gathers information

1.2 Types of malwareBased on the behavior of a particular malicious software we can determine its type as one of the following:Backdoor is a malicious program that will install by itself onto a computer to grant the attacker remote access.In most cases Backdoors let the attacker establish a connection to the computer with little or no authentication requirements and execute commands on the local system.1Botnet is similar to a backdoor , it helps the attacker to gain access of the system, but all computers infected with the same botnet receive the same instructions from a single command-and-control server.1Downloader is a malicious code that exists only to download other malicious code. Downloaders are commonly installed by attackers when they first gain access to a system. The downloader program will download and install additional malicious code. 1Information-stealing malware also known as spyware is a type of malware that gathers information from a victim’s computer and usually sends it to the attacker. Examples include sniffers, password hash grabbers, and keyloggers. This malware is typically used to gain access to online accounts such as email or online banking.1Launcher is malicious program used to launch other malicious programs. Usually, launchers use nontraditional techniques to launch other malicious programs in order to ensure stealth or greater access to a system.1Rootkit is a malicious code designed to conceal the existence of other code. Rootkits are usually paired with other malware, such as a backdoor, to allow remote access to the attacker and make the code difficult for the victim to detect.1Scareware is a sort of malware designed to frighten an infected user into buying something. It usually has a user interface that makes it look like an antivirus or a security program. It informs users that there is malicious code on their system and that the only way to get rid of it is to buy their “software,” when in reality, the software it’s selling does nothing more than removing the scareware. 1Spam-sending malware it infects a user’s machine and then uses that machine to send spam. This malware generates income for attackers by allowing them to sell spam-sending services.1 Worm or virus Malicious code that can make copies of itself and infect additional computers.1
