For True Cyber Security, Using a USB Firewall Is Essential

Using a USB firewall could be your best defense. More than likely, your computer automatically trusts any USB device that’s plugged into it. Hackers can use malicious code that’s injected to the USB’s drivers that will compromise a system. Not everyone is running a classified server or a nuclear program, so a USB firewall might be a bit of overkill for some. But who hasn’t bought a cheap thumb drive in a hurry. Malicious USB commands reach directly into your USB driver stack, exploiting your computer before file-based scanners realise anything happened. But the USG is the only plug-and-play BadUSB protection that does not require you to switch operating systems. It can even protect your legacy and embedded systems running out-of-date software... This internal link forms a firewall barrier that effectively blocks malicious USB commands from reaching your computer. Whether it’s this project that catches on or an improved version of the same concept, USB firewalls are a thing that needs to happen.

While trojans and email phishing still feature prominently in hacker toolkits, getting into a system IRL is one of the most effective methods a truly determined hacker can use. Using a USB firewall could be your best defense.

In the case of the Stuxnet virus that temporarily sabotaged Iran’s nuclear program, it was brought into Iran’s Natanz nuclear facility on a thumb drive by an Isreali double agent. Russia was able to break into a classified network by distributing virus-filled USB drives at retail kiosks around NATO headquarters in Kabul. Eventually, the right employee bought one and plugged it into the system that was completely unconnected to the internet.
