Types of Malware
Viruses and Trojans are two of the most common forms of malware. Using computer processing power and CPU cycles, the malware infects a computer and encrypts files. The victim is then denied access to the files. Often, the attacker demands a ransom in exchange for the decryption key.
Worms are another type of malware that can infect a network. These malicious programs spread from device to device. They exploit security vulnerabilities to infect and disrupt computers. They also steal sensitive information. They are difficult to detect and usually do not appear in the list of running programs.
Other forms of malware include adware, spyware, and scareware. These are all designed to lure users into installing unnecessary software and altering the way their devices work. They also can generate revenue for the operator of the adware.
Many of these types of programs are disguised as harmless, free programs. Cybercriminals often prank their victims by making the program seem legitimate. They may even pretend to be employees of software companies.
Depending on the type of malware, it can collect personal and financial data. It can also record what websites you visit, as well as the keystrokes you type. It can then send this data to hackers.
Another form of malware is crypto mining. Crypto mining malware is a method of infecting a computer and using its computing power to mine for bitcoin. This has become a lucrative business. However, it has recently seen a decline in popularity due to the drop in value of the currency.
