Common Fraud-Related Terms Defined: What do all those terms mean?

Malware (also known as a Virus). Short for “malicious software,” and refers to software developed by cybercriminals (often called “hackers”) to steal data and damage or destroy computers and computer systems.

Spyware. A type of malware installed on computers or cellphones to track your actions and/or collect information without your knowledge. Some spyware can change computer settings to send you to a malicious website instead of the one you intended to visit.

Cybercrime. Criminal activity carried out by means of computers or the internet.

Cybercriminal (often called “hackers”). One who engages in criminal activity by means of computers or the internet / uses the Internet to illegally break into computers.

Social Engineering. Methods cybercriminals use to get victims to take some sort of questionable action, often involving a breach of security, the sending of money, or giving up private information. These actions tend to go against our better judgment and defy common sense. However, by manipulating our emotions – anger, fear, and love, scammers can get us to stop thinking rationally and start acting on impulse without regard to what we’re actually doing. To put it simply, if cybercriminals use malware and viruses to hack our computers, then social engineering is how they hack our minds.

Phishing Attack. When a cybercriminal sends emails that trick users into disclosing sensitive information or downloading malware onto their computer or internet-equipped mobile device.

Identity Theft and Online Impersonation. These two terms go hand-in-hand– Identity theft is the fraudulent acquisition and use of a person’s private identifying information, usually for financial gain. This is followed by one of the most commonly committed cybercrimes in existence when someone maliciously uses another person’s online identity to gain financial benefits. This could include asking family members and friends for money, opening a bank account, or getting a loan in their name.
