"The policy tweaks show that big AI corporations will protect other big corporations when their users find ways to use LLMs to circumvent the artificial constraints that hardware manufacturers put on their devices. AI-powered copyright circumvention is OK with big tech when it’s a massive company scraping the entire internet to build their LLMs, but is not OK when people then use those tools to liberate their internet-of-things devices. It’s not the end of AI-powered reverse engineering, but people suddenly getting locked out of their accounts for asking AI to reverse engineer their gadgets suggests that the future of this practice lies in open weight, local, and uncensored models, making it less accessible to the masses and the people who could probably benefit from it most.

Tarun Gogineni, an OpenAI engineer, tweeted that people
are not supposed to have their OpenAI accounts restricted for reverse engineering: “these blocks are mostly accidental and a result of difficult decision boundaries; there is no prohibition against reverse engineering with codex. it’s getting fixed,” he tweeted.

But people who are doing AI-powered reverse-engineering suggest that they are moving away from big companies’ models to alternatives where they aren’t going to have their accounts disabled or have to figure out how to work around AI company guardrails."

"...as I’ve seen people take ownership and control back over the devices that manufacturers have purposefully bricked, turned into spyware, or have placed artificial limitations on, I have come to see AI-powered reverse engineering of electronic devices as one of the few LLM uses genuinely worth getting excited about. And so big companies have immediately taken steps to restrict this behavior. "

В конце сентября решила поковырять радиогид Retekess T130U/T131U. Был комплект, Flipper Zero и ноут с Linux. Стало интересно, как передатчик отправляет звук и переключает приёмники, и получится ли повторить это без него.

Начала со сканирования частот и захвата сигнала через CC1101 во Flipper. Дальше разбирала битовый поток: GFSK около 250 кбит/с, маркеры каналов, звук в G.711 A-law, служебные поля и CRC-16. Сначала удавалось воспроизводить отдельные захваченные кадры, а вот свои команды и звук приёмник игнорировал. Оказалось, недостаточно поменять нужные биты, нужно ещё правильно посчитать CRC и разобраться с преамбулой.

Для проверки звука я записывала своё мяуканье. Первые попытки звучали кошмарно, связь постоянно обрывалась. Но потом я наконец отчётливо услышала своё мяу через приёмник, переданное с Flipper. А следом смогла переключить T131U с CH19 на CH18 и обратно при выключенном родном передатчике. Позже сработали и команды для CH1, CH2, CH10 и CH17.

В итоге собрала экспериментальное приложение Retekess Suite для Flipper Zero. В нём есть приём и анализ сигналов, захват данных, передача короткого звука и управление каналами. Протокол ещё не до конца разобран, а некоторые функции новой сборки требуют проверки на железе.

Tom’s Hardware: Anthropic loosens Claude’s game cloning ban — AI will now offer to build original games in the requested genre. “The explosion of cloning and reverse-engineering games with AI has forced Anthropic to completely block its AI tools from executing these tasks. However, this has also negatively impacted game developers, who have started complaining that they can no longer […]

Desperado
Why don’t you come to your senses
You’ve been out riding guardrails
On the frontier side

I like to pretend I understand this word block.

“I am investing in hardware and trying to stay up to speed because the frontier labs guardrails will randomly change without warning on the same model. For my security research and pentesting work I really don’t want to invest tooling and energy into an ecosystem that will eventually lock me out. These guardrails on the frontier side have come at the same time as open weight models from (mostly) China are getting better and better.”

RE: https://infosec.exchange/@ESETresearch/117591559869846560

For malware REs the interesting parts are at the end:

• The use of Vtable Fixups to provide unmanaged exported functions from .NET binaries. As usual @washi has a good example of how to do this here, and more information: https://github.com/Washi1337/AsmResolver/issues/63

• Loading a malicious assembly by placing it in the .NET Native Image cache

• Adding malicious code around Exchange Transport Agents, by directly hooking them inside the transport agent management process EdgeTransport.exe
