Causing NT 4.0 MIPS to bluescreen without even trying

- In this stream we do some "fuzzing" of NT 4.0. We end up finding bugs so fast that we immediately start writing some triage tools. We mainly write a .DBG symbol parser and importer to Binary Ninja.

00:07:35 Why I'm getting 2gbps full duplex dedicated ethernet
00:24:15 How'd you learn about software eng at such a young age
00:32:30 Fixing a handle leak in our threading implementation
00:46:50 Fixing thread stack leak by having the thread free it's own stack
01:20:10 Creating 10,000 threads with no leaks!
01:21:50 Starting our "fuzzer"
01:37:05 "This shouldn't be able to find a blue screen"
01:52:00 Figuring out how to get information out of old crash dumps
02:02:20 mipskd.exe allows us to open dumps!?
02:26:40 "Scripting" KD with notepad find and replace to dump all symbols from the dump
02:48:30 Desu_Used claims 100,000 channel point reward to drop what I'm doing and rewrite it in Rust (symbol dumper)
03:07:20 Initial debug info parsing
03:14:40 Section header parsing
03:24:15 Debug directory parsing
03:47:00 COFF debug dircetory parsing
04:40:40 We have symbol names!
04:51:20 Trying to figure out how to associate file:line info with addresses
06:45:10 Okay we actually found a way to associate files with addresses, but it was really hard
07:02:00 Polishing up our DBG parsing code
07:26:20 Creating command line tool out of our DBG parser
07:33:40 Adding CAB support so that .DB_ files will automatically be decompressed
07:46:15 It works!!!
07:54:50 Writing README.md
08:02:11 Writing Binary Ninja script to consume tool output to symbolize binaries
08:54:25 Polishing our Binary Ninja script by turning it into a plugin
09:04:50 Success! Fully symbolized (and typed by mangling) Binja output, with source line comments!
09:16:50 Just browsing around NT code with our new tool! - Наука та технологія
"This shouldn't find a blue screen..." -Kappa
Lol really thinking hard about these life decisions 🤣
What vim theme is he using?
Default base16 dark I believe.
