9. TYPES OF MALWARE Phishing and Scam: Phishing is a type of social engineering attack that targets the user and tricks them by sending fake messages and emails to get sensitive information about the user or trying to download malicious software and exploit it on the target system.

10. TYPES OF MALWARE Identity Theft: Identity theft occurs when a cybercriminal uses another person’s personal data like credit card numbers or personal pictures without their permission to commit a fraud or a crime.

11. TYPES OF MALWARE Ransomware Attack: Ransomware attacks are a very common type of cybercrime. It is a type of malware that has the capability to prevent users from accessing all of their personal data on the system by encrypting them and then asking for a ransom in order to give access to the encrypted data.

12. TYPES OF MALWARE Trojan Horse Attack: A Trojan Horse (Trojan) is a type of malware that disguises itself as legitimate code or software. Once inside the network, attackers are able to carry out any action that a legitimate user could perform, such as exporting files, modifying data, deleting files or otherwise altering the contents of the device.

13. TYPES OF MALWARE Botnets : A botnet (short for “robot network”) is a network of computers infected by malware that are under the control of a single attacking party, known as the “ bot -herder.” Each individual machine under the control of the bot -herder is known as a bot. From one central point, the attacking party can command every computer on its botnet to simultaneously carry out a coordinated criminal action. The scale of a botnet (many comprised of millions of bots) enable the attacker to perform large-scale actions that were previously impossible with malware.

14. TYPES OF MALWARE Spyware: Spyware is loosely defined as malicious software designed to enter your computer device, gather data about you, and forward it to a third-party without your consent. Spyware can also refer to legitimate software that monitors your data for commercial purposes like advertising. However, malicious spyware is explicitly used to profit from stolen data.

WannaCry is a type of ransomware , a malware used to extort money by holding the victim’s data or device to ransom. The ransomware targeted a vulnerability in computers running Microsoft Windows. When the WannaCry ransomware attack hit, 230,000 computers were affected across 150 countries. Users were locked out of their files and sent a message demanding that they pay a Bitcoin ransom to regain access. Worldwide, the WannaCry cybercrime is estimated to have caused $4 billion in financial losses.
