- Malware: Malware is another type of virus which is used to interrupt, or gain access to unauthorized servers, computers, or network. Malware can be a worm, Trojan etc.
- Ransomware: Another common type of data breach is ransomware, which is used by cybercriminals to get access to the network. One the attackers get access to the network they gain the control of the network and lock it from use. A note within a virus is left on the network and the cybercriminals ask for a ransom to be paid. The owners need to pay that ransom to get access to the network again.
- Password attacks: Through this type of data breaches, the attackers target the passwords to get access to the network. They use multiple passwords to get access to the user’s personal information. They keep on trying different password until it works.
- Phishing emails: Phishing emails are also used to gain access to personal information.
