I like how you mixed this in with real suggestions.
- kragen 7y agoIt's an excellent suggestion if the code you're trying to communicate with is not actually the kernel, but rather other code on the machine that the kernel is attempting to prevent you from communicating with. Except for the ASN.1 part. That's never a good idea.
- waterhouse 7y agoOr code not on the machine. I remember: "PowerHammer: Exfiltrating Data from Air-Gapped Computers Through Power Lines" https://news.ycombinator.com/item?id=16821513 https://news.ycombinator.com/item?id=16821513

- int_19h 7y agoFinally, a perfect application for INTERCAL.
- dfox 7y agoNothing from that list is sane i386 syscall mechanism :). (Which given the fact that the list contains undocumented and obscure 0xf1 icebp and not documented 0xcc int3 seems to be the intention)
