http://phrack.org/issues/71/1.html new Phrack is out!

it you would like to read ~10k words about going from "a 12kb binary that fell off a truck" to "a disassembler that knows the whole instruction set except like five opcodes", all without running a single instruction, phrack 71 is up and has a treat from me to you: http://phrack.org/issues/71/3.html#article

The Minuteman III missile (1970) is America's land-based nuclear deterrent, with 400 missiles ready to launch. The missile used a complex guidance system with over 17,000 electronic and mechanical parts that cost $4.5 million in current dollars. Let's take a look at the guidance system and computer. 1/N

ProTip: the moment you'd put the first debug print in your supposedly long-running Python program is the right time to import logging instead.

thanks to @gsuberland's excellent work, we now have an in-depth dive into the technical details of the #GlasgowInterfaceExplorer hardware published on the website!

Recently, a Dutch hacker found a vulnerability allowing him to shut down 4 million solar power installations. A handful of mostly non-European places manage perhaps 100 GW of solar power in the EU. Any mishap there, or heaven forbid, a compromise, could easily shut down so much power that the European electricity grid would collapse. Shockingly, we regulate these massive control panels as if they are online birthday calendars. And that must change. https://berthub.eu/articles/posts/the-gigantic-unregulated-power-plants-in-the-cloud/

Although Talos was an *automaton*, it's a PITA to fetch vulnerability reports from @TalosSecurity automatically so I created a Fediverse bot:

I feel like if Google was in charge of Bell Labs, they would have cancelled the transistor project because it wouldn’t make as much money in six months as punch card machines

One of the simplest reverse engineering tricks I use daily is the fact that a lot of functions in a compile binary will be in the same (or reversed) order that they were in the original code.

If you find an encryption function, you usually don't need to keep reversing the code flow until you find the decryption function. The developer probably wrote them both at the same time, so they'll probably be adjacent in the code. If you know what a function does, there's a good chance the function directly above and below it are related, so will be easy to figure out.

This says that Windows still has low-level OS support for punch card readers.

Could someone with Windows handy try `echo test > PUN` and see what happens?

I recently became aware of a true abomination: https://github.com/open-abap/open-abap-ssh

Someone seriously looked at a problem and went "I know, I'll implement an SSH client as a script running on my ERP system".

I don't know what problem they could have possibly had, and I hope to never find out.

I'm experimenting with #NixOS and it's all good so far, chezmoi works like a charm, successfully cleaned up some Debianisms, etc.

Then I ran into the problem of shebangs o.O

My university faculty made the news by banning condoms in this years freshman camp (don't ask...).

Now a midwife offered discount for anyone getting pregnant there.

I'm not sure if she is aware of the ratio of compatible reproductive organs in the Elecrical Engineering and Informatics faculty tho...
