The first known RDOFF exectuable file which runs in nasm's deprecated rdx loader was demonstrated by me last year for BGGP6. The second known RDOFF binary is a virus that targets the first file (and any other RDOFF). It will be published in the forthcoming @tmpout@haunted.computer Volume 5.

Absolutely love when devs leave their custom protocol source in a random dir in their firmware file system. Thank you for your commitment to OSS.

This paper is pretty interesting, creating harmonic distortions via GPU workloads to attack data center power infra Bit2Watt: A Cyber-Physical Vulnerability Exploiting GPU Workloads Across Power and Computing Infrastructures https://arxiv.org/abs/2607.05993

Is there a term for when people spend exponentially more time trying to get an LLM to do a task correctly, than it would have taken to just do the task themselves?

Whenever I use Chrome to debug a modern website, it's so funny to see all the requests usually blocked by my normal setup. It's like watching a fish being released back into the sea, swimming happily, gobbling up all the data and sending telemetry out to the other fish.

It's honestly not particularly hard to attack critical infra, but if you do, you're just as bad if not worse than the people who ransomware hospitals.

This is the first year for BGGP that there are less entries than previous years! There are still 3 weeks left. Check out the repo and send in a weird little file!! https://haunted.computer/@binarygolf/115396651658784020

The first one is ASCII art, the rest are physical collages created with scissors, glue, stickers, stamps, typewriter, and photocopier.

@mattias@toot.bike @jyrgenn@mas.to thanks for explaining! This is what I did. I connected to the Wi-Fi access point and then did a scan and found the IPP port. I forget which specific Linux application could make it work, but it took some fiddling and trial and error. I didn't feel like doing that again today so I just tried the USB port for laughs and it worked!

For everyone wondering why I bought a cheap HP, I got it when I lived in a pretty rural area and needed to print and sign a document out by the morning. I got it at Walmart and it was one of the only printers there, and the cheapest by a non-trivial amount. It can be hard to find printing services for many people, and if you do it can be outrageously expensive. These ultra cheap printers are sometimes the best option for people. Anyone who buys or has one should also know that they don't have to make some HP account, download an app, or give them any info if they just need to print out a couple pages.

HP are such scammers

I posted about this very cheap printer before, which strongly suggests that there is No USB, only Wifi. When I first got it I figured out how to print over the network without using the app they try to bully you into downloading.

It turns out it's even easier to print, just use the USB port they try to pretend isn't there!

No company is going to rewrite their firmware to remove the USB stack. It's even more expensive to redesign the hardware to get rid of the USB port physically. They opted for the cheapest option, a little sticker.

They are just trying to store everyone's documents in their stupid cloud service that some teenage extortion group is going to break into and leak one day. Don't give them your data.
