Hacker Tricks And Prevention Techniques

In movies or TV series where hackers are involved, we may have seen them apply their computer knowledge in order to perform certain hacker tricks that saved the day.
From "The Matrix" to "Swordfish", hackers have been able to elevate themselves to the level of heroes with only a keyboard and a mouse. However, hackers attacks and hacker prevention is more difficulty, and complex, in real life.

Hollywood has a tendency to oversimplify things so the general public can understand them. After all, only a small percentage of the population has enough skills to perform this kind of demonstrations. So, if you want to prevent hacking there are some basics that need to be learned first.

Tricks And Techniques Employed By Hackers To Break Into Your System

The first most common technique used technique used by hackers is scanning. Hackers have created tools that scan computers for weak spots. It can be an operating system that hasn't been upgraded or a port in the computer that it is open without the knowledge of the user.

Hackers use this "open window" to get inside your computer in order to do whatever they want to do. The interesting thing about this is that these hacker tools are available for free in the Internet. So, with a couple of hours of instructions, almost every computer user can become a hacker.

Another way that hackers can access your machine is through malware: programs designed to capture vital information from your computer, like login users and passwords. Malware could be hidden in a PowerPoint presentation sent by email or even in an innocent Instant Messenger message window.

How To Prevent Hacker Attacks

Hackers are always looking for a way to get into computers of other persons. It can be something as simple as phising confidential information (like credit card or bank account numbers) to complex hacking routines that use your computer as a repository for illegal content (like music or movies with copyright).

Unfortunately there is no magical software to prevent hackers; and it will never exist. It doesn't matter how much money or resources you invest in designing the perfect system, someone will find the way to crack it. Even the biggest government agencies like NASA, CIA and NSA have been victims of hackers. And the same thing happens in the private sector with companies like Citigroup or Wal-Mart.
