Collaborate Disseminate
Computer criminals are constantly looking our for ways to infect computer systems at large. A recent security audit has revealed that hackers are using a 2008 cold boot attack which is still found in modern computers from all major vendors….Read more… Continue reading Cold Boot Attack from 2008 Still Affects PCs and Macs
Security researchers have revealed a new attack to steal passwords, encryption keys and other sensitive information stored on most modern computers, even those with full disk encryption.
The attack is a new variation of a traditional Cold Boot Attack,… Continue reading New Cold Boot Attack Unlocks Disk Encryption On Nearly All Modern PCs
I have a Macbook configured with a firmware password required to boot from any media other than the built-in NVMe drive. In theory, this means without my password you can’t boot from removable media. Is this enough to prevent… Continue reading Is setting a firmware password on a Macbook enough to prevent cold boot attacks?
I wrote a paper with a countermeasure for a cold-boot attack and am currently in rebuttal process.
One reviewer struggles with the motivation behind cold-boot attacks. Specifically, he asks if there is an example of a cold-… Continue reading Cold-boot attack example in the real world
How Secure is Storing Cryptographic Information into the CPU Register over storing it into the RAM?
And why is it currently not much used?
I know that this will mitigate a Cold-Boot-Attack which is one of the ways to “break… Continue reading How Secure is Storing Cryptographic Information into the CPU Register instead of RAM
I’ve looked at the documentation and it mentions that upon shutdown the data residing in the ram is overwritten, however it doesn’t go into any detail on how it does this.

As far as I know, there are two methods for performing cold boot attacks:
Reboot the system into an alternate operating system or BIOS with a minimal memory footprint which automatically exports memory to persistent media.
… Continue reading Methods of cold boot attacks in the wild
Using Linux, I have system and swap/hibernation partitions encrypted with LUKS, and data partitions encrypted with Truecrypt, and I am wondering when I put my laptop to hibernation if the encryption keys are wiped from the RAM before the c… Continue reading Are encryption keys wiped from RAM before hibernate, or how to do it (Luks and Truecrypt)
It was demonstrated that dram modules can retain information up to 10 min after power off in certain conditions. My question – are there memory types which will retain data 10 sec at max even if being frozen (aka cold boot attack)?
EDIT. I… Continue reading Are there volatile memory chips which dont retain data after power off?
