Hacking viruses are computer programs that can steal personal information and even control a system remotely. They are typically spread via emails or peer-to-peer networks, as well as websites that offer downloadable content. You can avoid a hacking attack by ensuring you update your software, staying away from downloading unreliable sources, and staying away from insecure networks.

Hacking viruses are employed by cybercriminals to attack their victims for a variety of reasons. They might wish to create keystroke logs that record all the words a device user types. This provides the perpetrator with everything they need to steal an identity and gain access bank accounts or credit cards as well as other important information. They may also use the compromised device as a part of a botnet, a network that can be used to send spam emails or to launch attacks on other devices.

A virus may also be written in order to control the functions of a device, such as changing the homepage or redirecting users to an unwanted web site or rearranging results of a search engine. This kind of hacking may be referred to as backdoor.

Hackers who were fascinated by finding low-tech methods of bypassing secure telecommunications and expensive long distance calls were called phreaks. Phreak is a combination of the words freak and phone. The majority of those who fall victim to hacking viruses today do not have anything to do either with telecommunications, or the tinkering of with technology. They are the unfortunate victims of malicious hackers that exploit vulnerabilities in built-in computer security systems to steal sensitive data or disrupt normal computer use and cause financial harm to the victim.
