Windows 10 Vulnerability Highlights Need for Physical Security Testing

During our more advanced Red Team penetration testing attacks, Raxis customers are often shocked to discover that we’ve not only been inside their network, but we’ve also been inside their buildings, their server rooms, and even their individual offices. It would take days to explain all the tricks and techniques we use to do that, so let’s focus on the more important question of why we do it.

The simple answer is that physical access to devices opens up a world of possibilities to an attacker. In fact a recent Forbes article about a Windows 10 security problem offers an excellent example of what can happen when a bad guy gets to spend a few minutes alone with your computer.

Notice in the article that Bjorn Ruytenberg says that a hacker with the right equipment needs less than five minutes of access to exploit the Windows 10 vulnerability… even if the computer is not on. The attacker only needs physical access to the device. This is an important finding because 95% of the time when Raxis conducts a physical, social-engineering assessment, we succeed in gaining unchallenged physical access to facilities and devices – even when armed guards are employed. Security is often perception, and our techniques commonly bypass guards, electronic devices, and employees. We often find unmanned workstations and usually find ourselves with these devices for far longer than the 5 minutes that Ruytenberg says it takes.

What’s the takeaway? In the real world, cybersecurity must complement physical security. In other words, patch your Windows but don’t forget to lock your windows as well.
