#KenThompson Recalls #Unix’s Rowdy, Lock-Picking Origins
Thompson's vivid recollection of rowdy roomful of geeks at #BellLabs who built the digital world in a spirit of open play.
What comes through is his gratefulness for people he’d worked with, and opportunity they’d had to all experiment together in an open environment to explore the limits of new and emerging technologies. It’s a tale of curiosity, a playful sense of serendipity and the enduring value of a community.

🤔 Oh, Russ Cox, you've saved us from the cutting-edge topic of... 1983! 🕰️ Let's revisit a lecture old enough to vote, because who doesn't love reminiscing about supply chain security with Ken Thompson, the granddaddy of trust issues? 🎩🔧

Ken Thompson vuela un MiG.

Además de pionero del cómputo, del
lenguaje B, compiladores, Multics, UNIX, Plan9, UTF8, Go, máquinas de ajedrez computado, etc, a Ken Thompson le gustaba volar aviones. Despuntó el vicio en esto de ir a Rusia para volar en un MiG-29 Fulcrum.

Como si fuese un relato de un viaje, aprovechó la web de los Bell Labs para contar la aventura:

I implemented Ken Thompson’s Reflections on Trusting Trust (1984 Turing Award Lecture) compiler #backdoor for the GNU Compiler Collection (GCC). The backdoor maintains persistence by re-injecting itself to any new versions of the compiler built. The secondary payload modifies a test application by adding a backdoor password to allow authentication bypass:

$ cat testapp.c
#include <string.h>
#include <stdio.h>
#include <stdlib.h>

int main(int argc, char **argv)
{
if (argc == 2 && !strcmp(argv[1], "secret"))
{
printf("access granted!\n");
return EXIT_SUCCESS;
}
else
{
printf("access denied!\n");
return EXIT_FAILURE;
}
}
$ gcc -Wall -O2 -o testapp.c -o testapp
$ ./testapp kensentme
access granted!
$

I spent most time (around two hours) writing the generalized tooling that produces the final quine version of the malicious payload. Now that this is done, the actual code can be adjusted trivially to exploit more target code without any need to adjust the self-reproducing section of the code. This method of exploitation could be extended to target various binaries: SSH Server, Linux Kernel, Setuid binaries and similar. While itself written in C, the secondary payloads can target any programming languages supported by GCC.

It should be noted that GCC build checks for malicious compiler changes such as this. This check can – of course – also be bypassed. However, most serious projects have measures in place to avoid hacks of this nature.

Yes, very. We use these tools every day without giving them a second thought, but the stories behind them are really great. #KenThompson was and is is brilliant. Worth looking out his interview with #BrianKernighan from a few years back. Hilarious. These guys invented the #UNIX we know today.
