Windows 11 hardware restrictions cannot be bypassed

TPM is vulnerable to physical attacks

There are TPM chips with a light sensor that, when detecting an intrusion, self-destruct. Despite everything, a person with physical access to the equipment can bypass the encryption system in half an hour using common hardware and without the need to perform soldering.

Reverse engineering the M1

Someone has been poking around in the innards of Apple's ARM processor that aims to replace the x86 CPUs of its equipment. This presentation shows some details of the work.

DDR5 continues to break records

As manufacturers develop their DDR5 chips, records continue to be broken. In this case, a manufacturer has reached transfer rates of 12600MT/s. Recall that DDR4 has a maximum rate of 3200MT/s.
