Hackers are the festering boil dreaded by any computer user. Today, many people suffer from computer hacks. But what are hackers really hacking for? Hackers generally attack home and office PCs connected via broadband because they want to wreak havoc, convert unsuspecting PCs into spam-sending machines, or steal information, generally for financial gain.
Hackers aren’t always the bad guys. Some are computer-intelligent people who enjoy delving into and deciphering computer systems. They may work inside each system to achieve the maximum performance possible. Many hackers have legitimate jobs to conduct analyses and create protection tools for computer networks as a safeguard against bad hackers.
Criminal hackers seek to break into a computer’s system through a weak spot in the hopes of gaining access to stored information, like credit card accounts, banking information, and any other personal or business information they can use for gain.
Hackers don’t just crack open computers for information. Often times, a hacked system can be used to bombard and attack websites, causing the websites to crash and cease to work properly. These attacks are known as distributed denial of service, or DDoS, attacks. Imagine if a hacker were able to penetrate major banking or government institutes with a DDoS attack. Chaos could ensue. Hackers can use PCs to send out waves of spam without the owners being aware of the hack until their Internet service provider calls about the complaints from other users.
Hackers can gain access to a PC through various channels. One route is via unprotected ports. Hackers can use a port scanner to do this. Another access point is malicious programs. Viruses, root kits, Trojan horses, and worms are various forms of malicious replicating software that can change programming, functions, and bring on the blue screen of death. To protect your computer, install and use a firewall and conduct regular virus scans and cleanings.
Not all hackers are bad, but don’t put your system at risk without need.
