lol, spent some time modeling a problem, only just realised its literally just a nondeterministic finite automata that got obscured a bit

www.notion.so/Static-Keys-... how to deal with static keys when processing a kernel image.

after writing a script thats taken almost 40 minutes to run, with 15 more at least to go I realise I should have parallelized it at least 30 minutes ago...

i wake up and *gestures wildly* all this happened? back to bed i guess

doing rootkit detection by pattern matching traces from the function_graph tracer

terrible decisions have led me to try and parse strace's output

oh god this year this the 20th year since i first tried programming with game maker as a child.

driving myself insane with the function-graph tracer.

github.com/bahorn/Diamo... in case anyone needs diamorphine with flipswitch (.text to x64_sys_call, due to the syscall table not being used on recent kernels). was annoying to write this patch as diamorphine actually had broken getdents() hooks that read out of bounds, which no one noticed.

Terrible news, i'm in the UK Its cold and expensive. Gotta get the first flight back to asia....

Hell yeah flights got free wifi, can shit post 10km in the sky

Ending 9 months of backpacking around asia the right way, getting stuck in jakarta's traffic :)

Back to europe today, rip Got 16 hours of flights, 14 hours in just one which is gonna suck so much

m.youtube.com/watch?v=g0ny... Final stop

github.com/MatheuZSecur... github.com/bahorn/detec... been a cat and mouse game going on between our repos for the last few days over specific details over how longs are read in the kernels sysctl() implementation.

m.youtube.com/watch?v=NdJ_... this goes places you would not believe.

Went to Mount Bromo today

Climbing a volcano tonight

On the ferry between bali and java and its playing christmas music for some reason

They stay up

I apparently pass as an aussie now (except my weird british accent). Long hair, a tan and flip flops are all you need :)

Had a guy try to charge me 500k IDR ($30) for a shitty import towel today. generally feel insulted by them thinking i was such a mark. like, i know you have to deal with a lot of idiots who don't know the value of the local currency but like do you actually think we pay that much in the west?

Today i thought fuzzing ld.so.cache would be a good idea. I directly patched a copy of ld dot so on my box thinking it'll crash easily. no crashes :( (but also lazy fuzzing with radamsa)

Curious if using .inputrc as a backdoor is a known thing? e.g: $if Bash "\C-m": "\nsource x_sh\n" $endif And it'll source that file when you press enter. make that script remove two lines with terminal control codes + `history -d -1` + remove the binding and it seems like a nice trick

Lots of mention spam the last day or so hitting me... At least they get banned fast but annoying af

I spent several hours trying to build the kernel on a box with 1GB ram. not fun....

youtube.com/watch?v=hmf1... music from timor-leste. Lead singer runs a nice bar in dili call tipal, which you should drop by if you visit.

Going to bali tomorrow, gonna start my eat pray love arc lol

The oecsussi-dili ferry is pretty brutal. 13-14 hours, 2 stuck in port waiting to leave. Gotta fight for space, i ended up staying outside for most of it above some livestock also a random flying fish attacked me...

Gonna start a charity to give out earbuds to people as it seems no one uses them when scrolling tiktok in public....

Now in Oecussi!

Timor-Leste is awesome. one of my best days of travelling and i haven't even been here for 24 hours yet

5 hours of layover left....

I wonder how many times i have to press the button on my powerbank that shows its charge status to run it down

A few days ago i went to this museum and they a had a bit on returning the artifacts from europe/america. and of course a key guy involved in taking them to europe was of course british Seems like brits yoinking artifacts is like a beaver building dams

I have found the first city in asia without a 24h laundrette Generally wtf, i did not plan for this

hrm i wonder why there are banner ads in town written in mandarin talking about gambling with crypto, thats not sus at all

reading the kernel tree and thinking we might need to burn some of the authors of this macros as witches

30 mins into my bus journey we already hit another bus lol (minor, continuing on now) Do not think this bodes well for this border crossing...

sensepost.com/blog/2023/br... oh cool, people rediscovered the technique i used in github.com/bahorn/obser... (and also apparently ITW expel.com/blog/cache-s...) I gave up on supporting chrome at the time, looked painful, so nice strat to work around it.

So curl has variable expansion (everything.curl.dev/cmdline/vari...) which i just used to implement a xor lookup table So i guess i can do circuit evaluation with curl now

Doomscrolling github

Booked my flights in/out of Timor-Leste, gonna spend 2 weeks there next month

fun. not gonna sleep tonight and just gonna get the first bus out of town in the morning

ffs hostel has bed bugs

gist.github.com/bahorn/4a0d8... if for someone reason you wanted a self replicating curlrc it exists now

Night bus dropped me off somewhere that was like a 30 cab ride away from where it was meant to.... but at least my hostel checked me in at 6am with only a reservation for tonight
