Re: Is encrypting the home folder enough?

For protecting against data theft and unauthorized access you can use: - FULL HDD/SSD real-time encryption with password at computer power UP ( you need BIOS and HDD/SSD firmware support and it will protect all data on HDD ). - BIOS power on password. ( you need BIOS support ). - Home folders encryp...

Re: Intel-microcode open source. Really? Where is it?

Some people still understand ASM, this is not the point. ~28 years ago I used to program in ASM self-replicate code that changed his form; compiled working code had final size under 2Kb. Have a look at microcode length, it size is from 2Kb to 100Kb... this is huge for pure ASM code just to correct s...

Re: Intel-microcode open source. Really? Where is it?

Spot on.
Intel microcode for sure it is Intel proprietary and encrypted.
It can contain anything Intel want including a bonus backdoor.

Re: ATTN!...Intel CPU owners (Spectre & Meltdown flaws)

I don't think i3-2350M have microcode update to mitigate Spectre / Meltdown yet.
check

Code: Select all

dmesg | grep microcode
and see if date is at least 2017-07-xx or newer.

Re: ATTN!...Intel CPU owners (Spectre & Meltdown flaws)

Because Intel can lose so much money that we can't even dream if they lose control of the damage and what a better way than to have everything fuzzy and minimize the impact of this problem with careful crafted PR statements.
Time is passing and other security problems will hold the news.

Lenovo and other play safe now because it is quick, cheaper and easy for them to add in BIOS a routine check that flip this rw/ro bit off/on and release a BIOS update but I doubt they will say that it is a production fault, maybe Intel will even compensate them in a form or other to solve this quick...

If you have a external programmer that can program this model of flash memory you can unsolder the flash and set that byte off, then solder back and you solved the problem. The same thing can b...
