I have a Dell laptop with Intel management engine and Intel boot guard enable.
As I want to disassemble the bios and try to bypass boot guard. I tried with IDA but it’s not working. Maybe I don’t use the good disassembler or… Continue reading Bios disassembly
If a laptop does not have BootGuard or other protection against BIOS and hardware tampering, what’s the easiest way to verify the integrity of the BIOS and hardware on the laptop, to know it hasn’t been tampered with?
Can I make md5sum for UEFI, BIOS firmware files because of the new LoJax malware ( https://thehackernews.com/2018/09/uefi-rootkit-malware.html ). If yes, how to?
I recently bought a Dell laptop and found out that Dell recommends to install a theft-protection system called LoJack. It is a system installed on the BIOS; if the laptop is stolen, it is possible to connect to their website … Continue reading Is it risky to install a theft-protection system?
I know that the OS is the boss of programs (once OS is loaded). Is BIOS/UEFI the boss of the everything before OS is loaded? Can an OS be a sitting duck for any BIOS/UEFI related malware?
In other words, can BIOS/UEFI delete… Continue reading Can BIOS/UEFI change OS code?
Recently I was given a somewhat crusty looking ThinkPad T400 that seemed like it would make a good knock around machine to have on the bench, if it wasn’t for the fact the person who gave it to me had forgotten (or perhaps never knew) the BIOS password. Cleaning the machine up, putting more RAM in it, and swapping the wheezing hard drive for an SSD would be a relatively cheap way to wring a few more years of life from the machine, but not if I couldn’t change the boot order in BIOS.

Complex closed-source firmware has the potential to be a security nightmare.
Let’s take for example the possible security and privacy implications of:
Intel ME firmware in Intel processors (and AMD equivalent: PSP)
the fir… Continue reading What are the options to reduce the potential attack surface introduced by complex and closed-source firmware? [on hold]
This demo shows that “evil maid attacks,” hacks where an attacker has physical access to a target computer, are not as complicated as you may think. Continue reading Watch a Hacker Install a Firmware Backdoor on a Laptop in Less Than 5 Minutes
