Some people, most likely secret services working for corporations tried many times to make obstacles to his work including (but not limited to): 1) Electromagnetic attacks on his computer which made its work slower, buses could not operate on full speed, network worked at 100 mbits instead of 1 gbits, many devices failed to work. Sometimes it was even difficult to boot the system after several continuous power cycles, it did not depend on a specific hardware operability, the same happened even if the hardware was replaced. 2) Targeted EMI attacks on his disk, most likely some wrong data was injected into SATA channel which was always noticed by ZFS pool and sometimes even led to pool crash. The same happen at his job to backup and mail server. Shorter SATA cables helped to stop this. 3) Attacks on chips in new SATA controller most likely via radio channel led to a half of the pool mirrors lost temporary 4) Video records in zone minder were deleted periodically 5) Many voice records available including today when his mother indicated pain in her body 6) On Russian forums these criminal morons threaten him for his mother health. It is called ganstalking against targeted individuals. According to Russian laws almost each episode of their activity shall be punished by bringing them to prison for a few years. And taking into account this a group of people - a criminal band and very many episodes, they must be jailed for the whole their life to avoid hurting lawful people. They shall be deported from Russia and never allowed to return back. The information discussed here about Intel CPUs is taken from public forums, he did not stole it from an Intel laboratory. Almost anyone using X86 hardware threatens its own country national security in favor of western financial security, since corruption in Russia is often supported and defended by secret services operating backdoors in popular computers in their own interests just to cover stealing money from the country.
Re: Intel CPU (in)security
> Inside every modern Intel CPU is a secondary CPU running an embedded OS with direct access to nice things like all the RAM, AES acceleration hardware, TMP etc. So we have since Core2Duo at least following : IntelME - can be vanished by Libreboot Important BLOBS (even in Coreboot) for hardware like RAM initialization - can be vanished by Libreboot Backdoors in the CPU to root it by some instruction sequence Spectre & Hyperthreading like CPU flaws - can it be vanished by software emulated VM? Yesterday on May 13 almost at the midnight my computer went to sleep without me asking it to. After returning it from sleep I could not run my browser from which I posted here anymore, though other browsers started. A try to run it from console indicated some LD lib or something like that problems. It is a ES2L board waiting to be reflashed to Libreboot, not sure yet to do it or not though ... Today my keyboard is very lazy to type, it seems like some type of an electromagnetic suppression, but it is a relatively old hardware and non USB keyboard, so it still works slowly :P I am afraid that modern boards like for Haswell have more undesirable features, most likely they even do not need Internet cable, WIFI is not needed either, though not sure how it works, may be by radio channel backdoors in the board and even in relatively modern HDDs or just simly over power line?

A firewall can't stop this. Fortunately, the people who could possibly order intel to do something like this doesn't care about your pirated movies, and it would be a PR nightmare if Intel actually used the power they have for anything less than national security, since the risk of something leaking would be too large.
