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

bert hubert 🇺🇦🇪🇺🇺🇦

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/

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.

Not documented here though: https://learn.microsoft.com/en-us/windows/win32/fileio/naming-a-file

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.

MIT gets rid of their Elsevier contracts:

“For MIT to continue to pay millions of dollars to corporations that lock up the scholarship that comes out of our own campus was just inconsistent with MIT’s history of supporting open education and research,” said Chris Bourg, Director of Libraries at MIT.

OpenAI: Disrupting a covert Iranian influence operation
OpenAI announced Friday (16 August 2024) that they identified and took down a cluster of ChatGPT accounts that were generating content for a covert Iranian influence operation identified as Storm-2035. The operation used ChatGPT to generate content focused on a number of topics—including commentary on candidates on both sides in the U.S. presidential election – which it then shared via social media accounts and websites.

The operation generated content about several topics: mainly, the conflict in Gaza, Israel’s presence at the Olympic Games, and the U.S. presidential election—and to a lesser extent politics in Venezuela, the rights of Latinx communities in the U.S. (both in Spanish and English), and Scottish independence. They interspersed their political content with comments about fashion and beauty, possibly to appear more authentic or in an attempt to build a following.

IOC provided.
