I assume that any information that is public is public, right?
Jurisdictional language is something different xDDD
to be precise, from the point of pure logic this statement is nonsense and does not make sense, but I have to sign it 😁

A bit of math bullshit, does not recommend, but with hints and simple run in the head it is not that hard.

Sorry I was watching "company values" necessary trainings, and I was just thinking, isn't it just a random thing? just a bullshit that company come up with and claimed these values to be "their" or am I wrong?
And I'm wondering, why even people bothered themselves with such useless thing like creating their values?

My friend has sent me that puzzle: You should enter the start gate and go out of finish gate. There are only red and blue walls that you can cross. You MUST NOT pass same colors twice, so if you entered red wall, you cannot use red wall anymore, only green…
Leetcode made me different. I straight away saw here graph problem and started building it, and was ready to code it, but during building found the solution xD
r => red (entered through red)
g => greed (entered through green)
r => red (entered through red)
g => greed (entered through green)

So, recently my GF tried to phish. They were using standard thing: message in telgram to vote for drawing. You go to website, and they ask to confirm your vote, so you enter number, and get telegram “signin” code. If you paste the code there, and you dont hae 2 factor auth - congrats, you are compromised
Gonna record the video about it, and ask you a question meanwhile. I didnt get how they transfer my phone number over the network:
In devtools when I pressed “send” (ofc I was testing them out of curiousity), I have seen just GET requests for some .js and .json files, with hashed/encrypted nonsense in path, along with obfuscated js, which seems to becode that calls telgram api, but this call never happens in network tab. Also when load the page they load bunch of .wasm.
Anyone seen this?

Like this: https://domain.com/56a7cd874776e3e37b022c8dded57bddac01031404615b103e8a9ef38ccaca30/Ea7c35J/qy49gkdrl14o.js
Is this some sort of dynamic encryption that is going on underneath, or is it something related to how telegram client works? As I didnt see entered phone number anywhere. Webrtc is not established, sockets are not as well, in network only these .js requests, and the code is in my telegram, so it is working. Maybe they compiled and patched TDlib or whatever this open source telegram thing called?

If you tell me how it transfers the phone number and provide me with simple code that emulates the same communication - I will pay you 5 eur 😁😁

If you solved one of previous dailies, it should be Medium, so I would not say it is that hard, the idea is the same.

I would not say that intuition is that easy to build, but once you've done it - it is fairly easy. For that you would need to know Kadane's algo, which is a good problem to remind about it

CAN YOU FUCKING IMAGINE, chrome does not show "preview" or "content" of the page that was before redirection, but Edge does show it?

Let me start.
Whenever you click on the "vote", the telegram page loads.
STEP 1. telegram-page.html (naming for simplicity, actually named "/pnbZeA4")
This telegram page is regular "document" request that loads bunch of js files:
- 4vt095smidla.js.
See screen 1.
STEP 2. telegram-client-preloader.js (actually named "/4vt095smidla.js")
This preloader loads telegram client loader and bunch of other .js files
See screen 2.
STEP 3. telegram-webworker-loader.js (actually named "/9nnoq789wklc.js").
This loader registers WebWorker that runs telegram client js. This webworker runs in separate thread so we actually don't see opened sockets to Telegram.
See screen 3
STEP 4 telegram-client-webworker.js (actually named "/vmu7hv3hxb8g.js") starts communication with telegram using websockets.
To see it in webtools, go to edge://inspect/#workers, and click "inspect" on all workers you will see
See screen 4, 5, 6
Attaching deobfuscated files (some of them are so large that I need to do it locally)
