@Arjun 😱

@Arjun bro...how do you even do that on an activa?

Arjun

@RajdeepSindhu only one hand is needed to drive activa.... the right one

Rajdeep Sindhu

@Arjun isn't there, a clutch on the left side? .__.

or is that a pedal in activas?

I don't know, I've only driven a bike...

Arjun

@RajdeepSindhu bike have gears

and clutch n stuff

activa are gearless

@RajdeepSindhu just race and break, much like a cycle

Rajdeep Sindhu

Nice, nice

Euler 2

it is quite easy to hide a message like cicada in an image

Rajdeep Sindhu

04:11

@Euler2 Yo, have you ever obfuscated code?

@Euler2 I think I watched a computerphile video about it once...

Steganography, right? ;-;

Euler 2

once, but when I looked at it later,

I couldn't get it

@RajdeepSindhu yep, and I didn't use any sort of website or software for this

quite easy with a terminal

Rajdeep Sindhu

@Euler2 not for me, bro

I don't even know how it works...just know that it's a thing ;-;

@Euler2 couldn't get what?

Euler 2

@RajdeepSindhu the obfuscated code

Rajdeep Sindhu

@Euler2 Isn't that, the point of obfuscating code, somewhat? T-T

Euler 2

yes

Rajdeep Sindhu

04:17

Euler 2

and hiding a message in an image with a terminal is quite easy
echo *message here* >> *image name here*

Rajdeep Sindhu

Well here's some obfuscated code...and a string that you'll need...lemme know if you can decode it

000001010001010000001101000000100001001100001000000011100000110100110101000100100000010000010011000101000000111101001101010011100011111100000010000100010000010000000000000100110000010000011100000000000000110100010101000000000001001001001101000101100000100000001101000000110000111000010110001100000000100000000011000100110000011100110111001101010001011000001000000011010000001100001110000101100010000100000100000010000000011000000111000100110100111000111101010000000000010100010100000011010000001000010011000010000000111000001101001101010000001100010001000000000001011001001101010011100011111100000…

Euler 2

04:40

dafuq is this

Rajdeep Sindhu

@Euler2 😏😏

Euler 2

i hope this isnt some sort of very tricky malware or something like that

Rajdeep Sindhu

Nah nah, of course not...

I'll just tell you one thing tho...it's a simple JS program.

ALLUN mathhemateeks ticchar :

"Beta $\cos$ to positive function hai, negativity absorb kar leta hai...iss liye hi to $\cos(-\theta) = \cos\theta$"

Euler 2

okay so its js

Rajdeep Sindhu

hmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm

Someone seems to be forgetting that if $\cos(-\theta) = \cos\theta$, then $\cos\theta = \cos(-\theta)$ too T-T

Euler 2

04:43

I am so stupid that I frickin generated an exe and used a disassembler

Rajdeep Sindhu

bruh ._.

and that string is not a part of the code, in case you didn't know that ._.

Arjun

@RajdeepSindhu he'd be amused to know that cos pi is -1

positive function ki -ve value aa gai surrrr

Rajdeep Sindhu

Arre beta feeling pe jaao...words pe nahi

Arjun

@RajdeepSindhu ah yes the usual line ☺

Rajdeep Sindhu

@Arjun now shh...and solb this kushion

Arjun

04:48

rajdy in fortnight

Euler 2

@RajdeepSindhu I give up, now tell me

Rajdeep Sindhu

@Arjun I didn't get it ;-;

@Euler2 Hold on, lemme see if it even works :D

Arjun

@RajdeepSindhu u find a bug in fortnight small but annoying but they refuse to correct it

Rajdeep Sindhu

woo, it does work

Arjun

so u join The company as coder and fix the bug and then leave the job

Rajdeep Sindhu

04:53

So basically, that long string is a combination of a lot of 8-bit strings...

Arjun

giga chad😎

Rajdeep Sindhu

@Arjun bruh 👏👏

and each of those 8 bit strings corresponds to an integer when converted from binary to decimal

and if you put together the character in the string that the integer values of the string corresponds to, you get some JS code.

@Euler2 want me to elaborate?

Euler 2

i get it i get it

Rajdeep Sindhu

😎

I made a really messed up python code to convert that string to the code, so here it is :

a = "0000010100010100000011010000001000010011000010000000111000001101001101010001001000000100000100110001010000001111010011010100111000111111000000100001000100000100000000000001001100000100000111000000000000001101000101010000000000010010010011010001011000001000000011010000001100001110000101100011000000001000000000110001001100000111001101110011010100010110000010000000110100000011000011100001011000100001000001000000100000000110000001110001001101001110001111010100000000000101000101000000110100000010000100110000100000001110000011010011010100000011000100010000000000010110010011010100111000111111…

Rajdeep Sindhu

bro please, I give up

@Euler2 that's a single string tho, right?

Euler 2

yes,

it was too long a message so I had to separate it into two parts

Rajdeep Sindhu

@Euler2 Same with my message but I just added a blank line at the top ;-;

Euler 2

by the way look at this website

crackmes.one

I have a whole text file where I store interesting websites like this ._.

Rajdeep Sindhu

05:08

@Euler2 Do share it sometime...

Euler 2

yes, later

Rajdeep Sindhu

Sure!

@Euler2 So, how do you use this thing? ;-;

Euler 2

codes for reverse engineering, etc.

all the files require a password, and it is crackmes.one or crackmes.de

Rajdeep Sindhu

Yeah, I saw that in the FAQ's too.

I downloaded that helloworld_encrypted.py file and what the actual f*ck is this ._.

@Euler2 btw did you make this? ;-;

Euler 2

first one is deadfish

by the way I dont always trust random files from the internet, neither should you

Rajdeep Sindhu

05:16

@Euler2 Is that a post on crackmes or something?

Euler 2

nope I made it myself

Rajdeep Sindhu

@Euler2 yeah you never know if it's just an educational file or a very messed up malware ;-;

@Euler2 btw, ever watched one of John Hammond's malware analysis videos? They're pretty cool.

Euler 2

yes

Rajdeep Sindhu

ooooooooooooooooooooooooooooooo, finally found the command I was looking for.

I wonder why I never thought that exec was used to execute commands from a string T-T

Euler 2

exec is a demon

Rajdeep Sindhu

05:22

Exactly what I was gonna say.

Same command for JS?

Euler 2

Q: javascript equivalent of python's compile and exec

In python, one can take a string containing python code, compile it and run the resulting code with exec. Can something similar be done with javascript (any implementation is good). My objective is to get something like javascript's eval but faster. Thank you

Rajdeep Sindhu

Euler 2

na frick

where do you find so many gifs?

Rajdeep Sindhu

@Euler2 Tenor has a lot...in this case, for example, I just googled "cat salute gif" and went over to the "images" section.

I personally like discord's gif search a lot...

Euler 2

joshworth.com/dev/pixelspace/pixelspace_solarsystem.html

look at this

Rajdeep Sindhu

05:44

@Euler2 Another URL from that notepad file?

This website is the first thing I'm preferring to use a trackpad on rather than an external mouse.

Euler 2

05:59

@RajdeepSindhu yes

I rarely find websites good enough to put in it

Rajdeep Sindhu

This website is....just wow.

Ok, finally finished scrolling through it all...let's see how long it took me.

$\approx$ 23 mins, damn

Interesting stuff...Imma go attend an ALLUN class now, cya later!

@Arjun Same ;-;

@Arjun Why no full screen? ._.

Also damn bro, 125%?

everytime someone enters u use 2 fingers...

just a click for minimise😎

Rajdeep Sindhu

👏👏

Wolgwang

@RajdeepSindhu I didn't hear...

Which episode?

Rajdeep Sindhu

11:23

@Wolgwang First one, I think.

When they were talking with the Raman guy...and he was mentioning some cities and reminding Vaibhav about the A3 batches in them, I guess...

Arjun

@RajdeepSindhu hisar

second last city mentioned

IIRC

Rajdeep Sindhu

11:44

Yup.

ALLUN Kota phakulti be laike :

Arjun

13:07

@RajdeepSindhu that paralysed guy in KF

great guy

Rajdeep Sindhu

@Arjun Never heard of him before ;-;

Btw, I noticed that Vaibhav's mom got her pallu stuck in the auto's window when leaving and now I can't overlook it 😭

14:18

Damn bro, that ending...

@Wolgwang Oooh, so that's who he is

That ending was, just, unexpected.

I would love to say some words but I'm afraid I can't do that without spoilers 😭

Also, the music at the end was naice.

Wolgwang

14:37

@RajdeepSindhu Everyone have watched it....IG so

Rajdeep Sindhu

14:48

@Wolgwang Welp, so I wanted the show to have a really dark theme, to criticize JEE culture and to talk about issues seriously, with a sad ending too...

And remember that part where Sushrut's "Kyu karna hai IIT, aisa kya hai IIT mein?" problem was solved by Jeetu Bhaiya's "IIT iss liye karo kyunki tough hai......" stuff...somehow? I personally didn't like that at all.

I wanted the show to leave it's watchers wondering about things and questioning them after they finished watching it.

About 5 minutes before the ending, I thought that the show didn't achieve that but that suicide at the end, I hope that that encourages some people to think about things, at least ;-;

Overall, it was okay, in my opinion.

@Wolgwang What do you think?

@Wolgwang btw, would you, by any chance, happen to know either of these people from FIITJEE : Udit Pahuja, Ritviz Aggarwal, Keshav Bansal?

the thing is that you are not allowed to run the code

just analyze it

note: I obfuscated the code AND encoded it with a cipher too.

Arjun

@RajdeepSindhu bansal sir

he started KOTA

like the whole

Wolgwang

@RajdeepSindhu They are from Jkuct, right?

@RajdeepSindhu I didn't find the show too relatable...

@RajdeepSindhu Something like orchestral...?

I am unable to find the name of that music...

Rajdeep Sindhu

15:43

@Wolgwang I have no idea, honestly, but they're friends of mine from school.

@Wolgwang Me neither...

@Wolgwang Yup, but I think a more accurate term would be choir music...or something ;-;

@Arjun Doesn't sound like a great accomplishment after what has become of Kota now ;-;

@Euler2 bro why you torture us? ;-;

I've personally never even analyzed obfuscated code so I'd like to start there ._.

Wolgwang

@RajdeepSindhu Do you know what Jkuct is?

Rajdeep Sindhu

15:58

@Wolgwang not at all ._.

yeah nvm

Got it T-T

Arjun

16:51

@RajdeepSindhu ditto

@RajdeepSindhu it didn't tho

i have a feeling they'll be making a season 3

btw the girl that dies was the only one i liked in the show (:

Arjun

17:18

@RajdeepSindhu say that to him now

lol

@Arjun Bro, we barely saw her ._.

@Arjun 😶

@Euler2 Would it even work after the encoding, tho? ;-;

okay so decoding it wasn't that hard, thanks to the fact that it begins with function and there's a URL in the array...

now the analyzing part 😭
