Top Security Threats from Spyware

From , former About.com Guide

As a consultant, you are privy to sensitive client data. It may be stored on your business computers, along with information, passwords and account numbers from your own business. And that makes you vulnerable to security risks, such as identify theft. Using spyware, cyber thieves are watching your every move, and are ready to steal valuable data from your computer. What threat does spyware pose to your consulting business?

Nuisance

Perhaps the least destructive type of spyware is the one that allows adware to be displayed on your computer screen. It takes up valuable memory, slows your connection, or can simply reset your home page to another site. None of these are desirable actions but they are also typically little more than an annoyance. Their threat level is low but it does still pose a risk. If this type of spyware makes it onto your computer system, it can also open the door to a more malicious version of spyware which can cause significant damage.

Tracking

Many spyware programs are designed specifically to monitor and record your behaviors, such as track websites you visit online, or monitor your use of other web-based programs. Again, the threat level is low, unless the program uses the information to also record data you are providing to the other sites.

Redirecting URLs

Spyware programs are also capable of redirecting your computer to a particular website, regardless of what URL, or website address, you type. By redirecting a URL, it can mean lots of extra money for a cyber crook. That's because businesses, legitimate and otherwise, often pay money for every visitor that's directed to their site. Using spyware is a quick, but illegal means to provide lots of visitors. Additionally, spyware could redirect you to a site that loads more dangerous spyware programs onto your computer. Again, it's a low-level risk that could become dangerous if it perpetuates the loading of more intrusive programs onto your system.

Shutting Down Systems

Spyware is also capable of activities such as completely shutting down your computer, or permanently erasing or damaging files. Valuable client files could be destroyed in a blink of an eye, making this type of spyware threat high-risk.

Acting as a Controlling Server

Another high-risk threat is spyware's ability to use your computer as a server. The spyware embeds itself in your computer and then acts as a remote server to distribute other harmful programs or images, without your permission. Suddenly, your computer is the vehicle for delivering malicious programs.

Identity Theft

Perhaps one of the highest risk activities of spyware is the fact that it allows your keystrokes to be logged. In other words, the software records pertinent information as you type it, such as passwords and credit card account numbers. Once that data is sent back to the spyware's originator, the cyber thief can do a great deal of financial damage to your company, or your clients' companies.
