Know All about Your Enemies (Part II)

Following the previous issue of Softex newsletter, we are proceeding to introduce you to your enemies, who are waiting for you to download any software or document from unsecured sites to invade your computer.

Here are more details on these threats:

A worm is an evolved form of a virus. Like virus, worms replicate and spread themselves but it happens on a bit larger scale. They not need a human action to replicate and spread and that’s what makes it more dangerous. 
It always seeks for network loopholes to replicate from computer to computer. Therefore, it is not recommended  to download any email attachments or to click the links friends share with you in a chat window.

 
Spyware , unlike any of the above, doesn’t harm your computer in any way. Instead, they attack you! Once installed on a system they run in background and keep on collecting user’s personal data. These data can include your credit card numbers, passwords, important files and any other personal stuff.It is always advisable to download and install software from trusted sources.

A backdoor is a method of bypassing normal authentication procedures. Once a system has been compromised, one or more backdoors may be installed in order to allow easier access in the future. Backdoors may also be installed prior to malicious software, to allow attackers entry.
It is worth-knowing that crackers use backdoors to secure remote access to a computer, while attempting to remain hidden from casual inspection. To install backdoors, crackers may use Trojan horses, worms, or other methods.
