This is the first in a proposed series of blog posts that plan to give an insight into the ways we devised to train up our team in hardware hacking tools and techniques. This first post acts as an introduction to the regime to show off each of the challenges we set up to train our team in the basics of hardware hacking. Subsequent posts will focus on how to solve some of the actual challenges used to train our consultants. Continue reading

If BuzzFeed ran an article titled “26 Security Features You Probably Shouldn’t Enforce From Usermode”, this one would almost certainly make the list. But, for whatever reason, I thought it would be a fun learning experience to try to enforce a W^X memory policy from usermode. Some of you are probably asking what the heck a W^X policy is in the first place, and I’m terrible at thinking of ways to start blog posts (case in point: this paragraph), so I guess we’ll start out there.

Lateral Movement is a method used by attackers (or malware) against a network Domain. After an initial device is compromised (typically, a user’s workstation), the attacker extracts passwords from memory, or obtains encrypted password hashes from the system for cracking or direct use (i.e. Pass the Hash). The attacker then attempts to login to other systems using those credentials to search for cached passwords of privileged Domain accounts. Usually, the local Administrator account is targeted as the password is often the same on all systems (due to the common practice of deploying systems from a master image), but service accounts, etc. can also be targeted.

Modern autonomous vehicles use a number of sensors to analyse their surroundings and act upon changes in their environment. A brilliant idea in theory, but how much of this sensory information can we actually trust? Cisco’s Security Advisory R&D team, a.k.a. Portcullis Labs, decided to investigate further. Continue reading
