Ransomware infects your computer, then encrypts confidential data, such as personal documents or photos, and demands a ransom for their decryption. If you refuse to pay, the data is deleted. Some types of ransomware can completely block access to your computer. They can pass off their actions as the work of law enforcement agencies and accuse you of any illegal acts. In June 2015, the Center for Receiving Complaints about Fraud on the Internet at the FBI was contacted by users who reported financial losses totaling $18,000,000 as a result of the activities of the CryptoWall ransomware virus.

  1. Bots

Bots are programs designed to automatically perform certain operations. They can be used for legitimate purposes, but the attackers have adapted them for their malicious purposes. By infiltrating a computer, bots can force it to execute certain commands without the user’s approval or even without the user’s knowledge. Hackers may also try to infect multiple computers with the same bot in order to create a botnet, which will then be used to remotely control hacked machines – steal confidential data, monitor the actions of the victim, automatically spread spam or launch destructive DDoS attacks on computer systems.
