Phishing occurs when an email or text appears to be sent from a reputable source but is actually designed by cybercriminals to trick the recipient into sharing sensitive information, such as passwords. Phishing is one of the most common attacks on consumers.
Malware is malicious software intended to cause damage to a computer or network. Types of malware include viruses, worms, spyware, and ransomware. Malware can find its way onto computers when a user clicks a link or email attachment that installs malicious software.
An eavesdropping attack is a theft of information as it is transmitted over a network by a computer, smartphone, or another connected device. Cybercriminals take advantage of unsecured network communications to access data as it is being sent or received by its user.
Denial-of-service attacks prevent the rightful user from accessing a system. A common method used in this type of cyberattack is entering an incorrect password enough times that the account is locked.
