a fun part of reverse engineering is encountering Mystery Acronyms with no known canonical definition, so you get to make up your own

anyone know if there is any way to have a type like `struct SizedSlice<T: Sized, const N: usize>([T; N])` without exposing `N` to the user of the type and still maintain the `Sized` trait bound on the `SizedSlice` type itself?

it feels like it should be possible to do it without `N` bubbling up

i have a feeling the ustr.gov XSS is going to go unnoticed by them, but i reaaaally don't want to give this administration the satisfaction of being able to silently fix their shite website

fair, i guess for cases where an attacker can only observe the network noise really makes the timing leaks much less helpful

would y'all consider AES with precomputed T-tables in practice a vulnerability (because of cache-timing attacks) or is the attack so theoretical that it doesn't really matter?

a snippet of rust code which contains `let None = bar else { unreachable!() };`

a snippet of rust code which contains `let None = bar else { unreachable!() };`

it's kinda funny how rust's let-else statements can lead to interestingly misleading code:

rednote messages from 7 large rednote creator with the top 3 saying "security", "through", "obscurity" and the rest just "."

rednote messages from 7 large rednote creator with the top 3 saying "security", "through", "obscurity" and the rest just "."

turns out rednote allows you to fabricate any conversations between anyone

yet they still don't respond to emails about this

thank you so much!

i feel like i came across unencrypted Chat messages as i looked into the app, but it is likely that those ended up being a different packet type and that the app just always encrypts "Chat" messages everytime. it might have been an attempt of having security perhaps

i don't know too much abt it personally. there was a case of qq browser being scrutinized for using non-cryptographic PRNG before. and looking into wechat there does seem to be another proprietary protocol but at a quick glance backed by actual cryptography

yep, the encryption pretty much acts more as obfuscation than encryption and you can even end up authenticating with this API without needing to know the encryption is a thing that happens.

the authentication is always in plaintext and you can then just find the "send message" proto and send one

TikTok alternative RedNote (Xiaohongshu) fails basic security measures Reverse engineering RedNote's app to identify security and privacy concerns

An infographic. There are six panels.

1. "Slow internet. Alt text is shown in place of unloaded images." a drawing shows a phone with poor signal, and alt text is visible where the image should have loaded.

2. "Findabillity. Alt text helps to search content." A drawing shows someone searching 'dog with banana' and a post is shown underneath without the words 'dog' or 'banana'. It is implied to be part of the alt text.

3. "Screen readers. Alt is read out to people using text-to-speech software". There is a drawing of the output a screen-reader would show when viewing an image with alt text on bluesky.

4. "Translation. Alt text can be translated". A drawing shows a post being translated. The alt text is also translated into german.

5. "Readability. Text in images can be made legible" There is a drawing of some truly awful handwriting inside a speech bubble. The alt text clarifies what the text is supposed to say.

6. "Disambiguation. Description helps clarify intent." There is a drawing of a post with a picture of a creature. This is styled after the famous optical illusion of a rabbit and a duck. The alt text clarifies that the animal is a rabbit. It definitely looks more like a duck.

Generally we think of alt-text as the domain of those with accessibility needs.

However alt-text is useful for many reasons, which benefit your viewers, as well as you, the creator!
