Hacking viruses are malicious computer programs that can take personal information and remotely control a computer. They typically spread via email, peer-to-peer networks and websites that offer downloadable content. It is possible to prevent the threat of a hacking virus by keeping software systems up to date and avoiding downloading from faulty sources and avoiding unsecure networks.
Hacking viruses are used by cybercriminals to attack their victims for a variety of reasons. They may want to infect computers with keystroke loggers that record every word a device’s user typed, giving the perpetrator everything they need to take their identity and gain access to bank accounts, credit card details and other valuable data. They may also utilize the compromised device as a part of a botnet network that could be used to send spam emails or to launch attacks on other devices.
A virus can be written to control the functionality of a device by changing the homepage or redirecting search results to an unwelcome web site or even replacing the results of a search engine. This kind of hacking is known as a backdoor virus.
In the past, hackers who relentlessly tried to find low-tech ways to evade secure telecommunications and expensive long-distance telephone calls were referred to as phreaks (a combination of freak and phone). The majority of people who are victims to hacking viruses today have nothing to do either with telecommunications or the tinkering of with technology. They are the unfortunate targets of malicious hackers who exploit weaknesses in security systems for computers to steal sensitive data, disrupt normal computer use and cause financial damage to their target.
