The newest Android phones use the Qualcomm Snapdragon 855 chipset with its TrustZone/TEE. The Android OS makes sure that a stolen phone, in its assembled form, is not usable.
Does Trustzone further prevent the CPU from bein… Continue reading Anti-Theft Mobile CPU
I used the spectre-meltdown-checker, version 0.42, without any option resulting in all-green results. But, in a help page, I found the –paranoid switch, which resulted in about a half of later CVEs to become red. I read what… Continue reading Sacrificing 30% of my CPU performance (by disabling Hyper-Threading) to fully mitigate CPU vulnerabilities, necessary?
The may very well be the smallest homemade TTL CPU we’ve ever seen. Measuring at one square inch, this tiny chip boasts 40 connections, an 8-bit databus, a 16-bit address bus, a 64 kB memory space, reset and clock inputs, and 5 V power lines.
TTL (transistor transistor logic) logic …read more

If you ask people how they rate as a driver, most of them will say they are better than average. At first, that seems improbable until you realize one thing: people judge themselves by different criteria. So Sally thinks she’s a good driver because she goes fast. Tom’s never had …read more
How quickly could you make an entire computer from 74 series logic, from scratch? [Richard Grafton had only 30 days until the UK’s Retro Computer Festival and set out to design and build his Cambridge-1 computer in that time. The result is a machine spread across several breadboards, with neatly …read more
In a recent article in Nature, you can find the details of a RISC-V CPU built using carbon nanotubes. Of course, Nature is a pricey proposition, but you can probably find the paper by its DOI number if you bother to look for it. The researchers point out that silicon …read more
Dozens of insecure drivers from 20 vendors illustrate widespread weaknesses when it comes to kernel protection. Continue reading Driver Disaster: Over 40 Signed Drivers Can’t Pass Security Muster
AMD announced that Google and Twitter are among the companies now using EPYC Rome processors during a launch event for the 7nm chips today. The release of EPYC Rome marks a major step in AMD’s processor war with Intel, which said last month that its own 7nm chips, Ice Lake, won’t be available until 2021 […] Continue reading Google and Twitter are using AMD’s new EPYC Rome processors in their datacenters
Researchers demonstrate a new side-channel attack that bypass mitigations against Spectre and Meltdown. Continue reading New SWAPGS Side-Channel Attack Bypasses Spectre and Meltdown Defenses
Security researchers at Bitdefender have discovered a way of exploiting a flaw in Intel chips that could be used to steal passwords and encryption keys.
