What Is Cybercrime?
Cybercrime is the use of a computer or network for illegal purposes like stealing money, trafficking in child pornography and intellectual property, and committing fraud. With a global economy that increasingly relies on information technology, the threat of cyberattacks is a constant and growing risk for businesses and individuals alike.
The most common type of cybercrime is unauthorized access to data and systems. Criminals gain unauthorized access through various methods including malware, ransomware attacks, hacking, and phishing. Cybercrimes often cross national borders – attackers, victims and technical infrastructure are all connected globally, making investigations more complex.
For example, a cybercriminal can attack a company with a ransomware attack, where they encrypt all of the company’s data and demand payment to regain access. A malicious actor can also exploit a flaw in a system, server, or application by exploiting a zero-day vulnerability, which is a security flaw that becomes public knowledge before a patch has been applied.
In addition, cybercriminals can also steal and sell personal information such as credit card details or social security numbers. They can also extort companies and individuals by demanding a ransom for the return of sensitive information or by threatening to shut down a business. They can also violate privacy by sending embarrassing or damaging content to others or stalking people online.
