While computer systems have undoubtedly changed the way we do business, there are downsides to this, with one of the biggest being security. It’s challenging to keep your systems completely secure, especially since new threats are uncovered on a near daily basis. That’s why you need to keep abreast of new potential threats and adopt trusted IT security services too. One of the latest issues to come to light is a device that can infect your computer when connected to a USB port.
While USB threats aren’t anything new – USB thumb drives are well known to be used by some employees to copy and take important files with them when they leave the office – this latest threat is a little different. Hackers have developed a USB stick that can bypass Windows Autorun features and infect your system.
How do these drives work?
As you may have noticed, when you connect a device like an external hard drive to your computer via the USB port, Windows will not run, or open the drive. Instead, you will get a window with a number of options, including: Open folder to view files, Download pictures, Play files, etc. The reason for this is because hackers figured out a number of years ago how to put a virus on a USB stick, which when plugged into the computer, would be auto run (started up) by Windows and infect the system.
Hackers have recently figured out how to trick this feature. What they have done is create a flash drive that looks like a USB memory stick. Only, when you plug it into a computer, Windows thinks it’s a plug-and-play peripheral like a keyboard, and will allow it to run. There is memory on the stick, where hackers can write and store a virus or infection, which will then run, infecting the system.
There are four things to be aware of with these drives:
What does this mean for my company?
Because these devices are nearly indistinguishable from real memory drives, it is nearly impossible to spot and therefore stop them from infecting systems. Because these drives are currently hard to find and infection rates are generally low, many companies probably don’t have to worry too much. However, you can bet that these drives will probably become more popular in the near future.
This doesn’t mean that you don’t have to be aware of this risk and understand that these drives exist. Some companies have started to take action by disabling USB drives, monitoring what employees plug into their drives and even providing employees with tamper-proof USB drives.
One thing you might have to concern yourself with is if you allow employees to bring in their own drives. In general, if you take steps to ensure that the drives being used are legitimate and approved by the company, this shouldn’t be much of a problem. Of course, keeping your security systems and anti-virus scanners up to date and functioning is always a good idea.
