Software keyloggers are programs that can be unintentionally downloaded as spyware or deliberately installed by a hacker. These programs enable someone to steal data from your computer as you type on your computer keyboard. In short, they log your key strokes. Worse yet, the frequency and sophistication of keylogging programs has risen dramatically over the past two years. This security threat is particularly troublesome because some keylogging programs can run without most antivirus and antispyware programs flagging the threat when a keylogger is present. Login names, passwords, credit card numbers and bank account numbers are just a sampling of the kinds of information that keyloggers have successfully stolen.

Fortunately, there are programs specifically designed to protect against keyloggers. At the outset, check with your antispyware vendor to see if their product effectively addresses the threat. If the answer is no, or you have no antispyware vendor, consider investing in a software product specifically designed for this task such as Spycop at www.spycop.com, PestPatrol at www.pestpatrol.com, XoftSpy at www.xoftspy.com or SnoopFree at www.snoopfree.com. While not a recommendation, these products represent a great place to start researching the tool. There may also be additional steps that one can take to prevent the unwanted installation of a keylogger. As always, discuss the concern with your IT staff or consultant and follow through on implementing any recommendations.

One final comment, this tip focuses on software keyloggers. Be aware that hardware keyloggers do exist and software programs are not able to detect their presence. In fact, keyboards with built-in keyloggers (thus making it impossible to detect visually) are available for purchase. These keyboards have the capability to capture a year or more worth of typing. Here prevention, such as locking up systems when not in use or visually inspecting cables, is key.
