Hacking: Diagnosis and Prevention
Published: 15th April 2006 | Source: Overclock3D |
In this day and age virus's are the least of your worries: hackers and spyware are by far the most virulent and cunning of all online security threats. Let me show you how to declare war on the enemy, by first diagnosing you and your PC's threat, taking the correct course of action and then implementing preventative measures to minimise the risk of it happening again. Online threats are no longer restricted to just bringing down your PC; cybercriminals are now capable of tracking your every move and targeting web sites, such as those of banks, where you log personal data. Understanding the basics of how hackers work , is the first step in arming yourself against your system being compromised.
No PC - and no PC user - is safe from assault. Faster, always on internet connections, make it quick and easy to send or receive information, but the downside of broadband is that it increases the potential for net crime. Larger companies with a healthy bank balance are an obvious target for high-tech criminals, but such denials of service involves banks of computers sending out bogus requests simultaneously. To do this, the hackers need control of multiple PC's and are therefore constantly on the lookout for suitable hosts.
As well as exploiting your PC'sweb connection for destructive acts, hackers may also find the data stored on your PC invaluable. Malware in the form of keystroke-logging software hides itself within your PC and reports everything you type to the person that planted it there. If a hacker takes over your computer, they can have a rummage around for themselves, investigating any unencrypted files or folders, uncovering financial details and any personal data.
Most recently, there have been numerous scams to get you to reveal bank or credit card details (commonly known as 'phishing'). Data searches to find unencrypted passwords are very common too. In the wrong hands, such personal details can be used to 'impersonate' you, take out loans using your good credit rating and so on. There is, however, a number of ways you can protect your computer from virus's, scams and hackers. Lets look at the tools to help you clean up and protect your PC from trojans and other attacks designed to compromise your system.
