Anyone following the Intel vulnerability? Anonymous 01/05/2018 (Fri) 00:57:21 [Preview] No. 12159
The "Meltdown" and "Spectre" thing. Here:

Does it have any connection with the Sandsifter research?

From what I can tell, meltdown and spectre are problems involving the order in which the CPU's implement instructions due to speed optimizations.
Sandsifters is checking for unknown instructions, not the order of the instructions.

Also, I think Spectre affects both AMD and ARM as well, while Meltdown affects mainly Intel.

Ok, thanks.

Yeah but spectre is basically nothing, it's come out at the same time as meltdown to soften the blow to Intels' image but it takes months to achieve and even then it's theory. It's pretty much an NSA only level attack and still it's apparently hit or miss.
The real news is meltdown which is a huge fuck up from Intel and the fact the CEO sold off all that stock which is insider trading.

The picture isn't going through. Maybe jpeg will work.

Maybe because it's a 55MB jpeg. Resize and compress this thing, please.
Also, for graphics use png (pngquant), not jpg.

Well fuck me. I have been hoarding old IBM ThinkPads, thinking they were secure machines. There were also some sayings that even MIPS, POWER 8 and POWER 9 were affected.

If you wanted to be safe, airgapping your machines would be the best bet or having a ARM-based computer work as a strict firewall and share internet via a LibreWRT powered router. Pinebook64 sure does look tempting since it has ARM A53 and it wasn't affected by any of these apparantely.

Throw the guts, design a MIPS board, put the board inside and you are good to go.

>64-bit ARM

This shit list is ancient, many advice noe defunct tks to Spectre. MMU needs needs to be rethought, if not completely removed.
>>>/os/ iirc is gone

Mips or risc-v?

Such as...

"Intel engineers attended the same conferences as other company engineers, and read the same papers about performance enhancing strategies – so it is hard to believe they ignored the risky aspects. I bet they were instructed to ignore the risk," - deraadt

Holy smokes. He also thinks that way.
It's one of the (possibly) many backdoors from some security agency.

Doesn't this mean we now have a reliable way to hack just about any computer back to 1997? That is good news if there are any video game consoles that haven't been hacked yet. They should use this to crack all of the latest systems and get around any patches made to the PS3 or other old systems.

Spectre is kind of a big nothing. Meltdown is the real bug, which doesn't affect risc systems like game consoles.

Not the same guy, but, PS4 is not RISC, it's CISC, from what I know. I think xBox is CISC too.
Only PS3 used a Cell processor...
But Meltdown would only allow to get the memory, not to take over the "anti-cracking" system, because it probably needs a Sony server authentication.
