can anyone help me make something better on memory in python than this? maybe fetch text file and next index number every time rather than caching the whole file?
it just crashes for me as i'm trying to compare rockyou.txt to something
||python -c '
lines_to_remove = set()
with open("file B", "r") as f:
for line in f.readlines():
lines_to_remove.add(line.strip())
with open("file A", "r") as f:
for line in [line.strip() for line in f.readlines()]:
if line not in lines_to_remove:
print(line)
'||
subtle coyote
What do you mean you’re trying to compare rockyou with something?
rigid tapir
remove lines that appear in rockyou.txt from easyctf.txt
rigid tapir
awk 'NR==FNR{a[$0];next}!($0 in a)' <File1> <File2>
crashes in bash too.. granted my vm only has 4gb memory, tried loads of different ways using comm and diff, nothing works properly
So I imagined in Python there must be a way to make it more memory efficient by grabbing a line number each time instead of sticking the whole file in memory
subtle coyote
You can but I’m on my phone so I can’t type it out rn
That’s an easy way to do it with bash^
magic falcon
That operation can't really be made 'more memory efficient'. You could divide up the file into chunks and process each chunk - but then additional loads my be needed to ensure all keys processed.
subtle coyote
rigid tapir
I can't understand how it crashes if the files are 133.4MiB / 38.5 KiB . Unless it's being very inefficient. I will try a per line version
subtle coyote
You don’t have to load more than 1 line into memory at a time
If you look at that last link
rigid tapir
I promise I will fully learn python in the future but for now it's a copy/paste! food now so brb but thanks!
subtle coyote
@rigid tapir type it out instead of copy paste
It’s weird but I promise it helps you learn
rigid tapir
<@142724098328494080> type it out instead of copy paste
After much trial and error, i think it was the f.readlines() that was causing the memory spike. afte rremoving readlines() it worked:
||lines_to_remove = set()
lines_we_want = set()
with open("/Labs/easyctf/rockyou.txt", "r") as f:
for line in f:
lines_to_remove.add(line.strip())
with open("/Labs/easyctf/new.txt", "r") as f:
for line in f:
lines_we_want.add(line.strip())
for line in lines_we_want:
if line not in lines_to_remove:
print(line)||

What’s up
I'm trying to parse a .nmap with my script. I want to grab a section of output related only to a single port. Getting the start point is easy, but it keeps printing after the section, even if I give it regex to stop.
sed -e '/^$port/tcp/,/^([0-9]{1,5})/tcp/p' target.nmap
What I want it to do is stop printing when it gets to the first occurrance of the regex.
subtle coyote
Find an end character to split on and grab the stuff before that
magic falcon
I usually grab the .gnmap file for that kind of post processing.

Hello
So i m trying to make a password guesser which has 10 digits
this is my code
function generateCode() {
var code = "";
var chars = "0123456789";
for (var i = 0; i < 19; i++)
code += chars.charAt(Math.floor(Math.random() * chars.length));
return code;
}
function main() {
document.getElementById("redeem_code_token").value = generateCode();
document.getElementById("redeem_code_submit").click();
}```
setInterval(function() {
main();
}, speed);
so wat i want to know is..
When the computer gets the pass the computer clicks enter
and keeps on doing tat
but i was wondering tat the computer does not click enter but gets the pass coreectso the computer does the guessing on another server when it gets the real pass it will tell us the pass
do u guys get me
??
i m really new to the hacking and all btw
spiral glen
?
tepid cargo
wut the heck
spiral glen
what??
tepid cargo
check the pinned msg. by muiri on how to make code blocks in discord
spiral glen
ok
tepid cargo
oh so u want to generate a password that would be fed into the inputbox and will be clicked enter. if it works ur js script should stop?
spiral glen
no
so the compter randomizers number a clicks enter to see if its coorect
but i want the computer to not click enter i want it to guess the number.but not click enter. but the computer should still know if its correct or wrong
example
when u try to figure out a pass of the iphone and keep on trying the iphone will lock right
but this time it should not lock but the computer should still know if the pass is correct or wrong
Do you get me
?
tepid cargo
oh that will be dependant upon what is the code that Checks the password is.
if it's an xhr/ajax u have do the xhr request in order for you to know. this will probably lock u out after some tires.
if it's client side code u can just run that client side code.
the best way would be somehow to get the encrypted password or hash from that application and cracking it on ur machine.
so yeah. without calling the validating function no matter what the form, it's impossible to know
spiral glen
so is it possible or not
tepid cargo
as i said. depends on the validation code that u got.
it might be impossible it might be possible.
spiral glen
oh that will be dependant upon what is the code that Checks the password is.
if...
so wat is the easyest way to crack a pass
tepid cargo
there is no easiest way. password cracking takes a lot of research. rule of thumb, dictionary attacks are your best bet.
cause bruteforcing takes like forever to complete
spiral glen
lemma do some reaserch on thumb dictionary attacks
thks
is the attack called thumb dictionary
i googled it and no results
tepid cargo
no no. "dictionary attack" is the attack name.
i said "rule of thumb" sorry for the absense of punctuation marks.
tepid cargo
what do u mean.. just google "password cracking dictionary attacks" or somehting along the lines.
thorn moon
but i want the computer to not click enter i want it to guess the number.but not...
The situation you're asking about is what you'd do once you have the stored hash of a password. With the password hash, you can brute force it by hashing as many passwords as possible until you find a match with the hash. However, without the saved password hash, you have to go through whatever login system there is. And the reason systems make you wait longer after each failed attempt (or lock you out completely) is specifically to prevent exactly what you're trying to do 🙂

dry bluff
sorry. it's a good amount of code and really don't have that kind of time right ...
bro i findout the bug
the bug //sock=socket(AF_INET,SOCK_STREAM, 0);//
it is the imposter
tepid cargo
why
?
cause syntactically it's correct. AF_INET == ipv4 and sock_stream== tcp and 3rd param i don't know 🤣 just know that all that time it is set as mostly 0
dry bluff
cause syntactically it's correct. AF_INET == ipv4 and sock_stream== tcp and 3rd ...
everything is ok but i cannot fix this sock line
tepid cargo
u changed the server_address.sin_addr.s_addr right?
dry bluff
yeah exactly 🤣 it shouldn't be "MY IP :)"
😦
tepid cargo
i don't know how this code works, if the server binds to another socket or something. depending upon that it should be either localhost or the socket ip or ur ip.
dry bluff
but its work it is from google
tepid cargo
server.sin_addr.s_addr = inet_addr("xxx.xxx.xx.xxx"); u can see the ip being put here.
and please check pinned msg on how to create code blocks
if it's reverse shell then it should connect to ur IP. if it's bind shell it should connect to localhost.
so if u understood from udemy u can change it depending on what the program is doing.
I would suggest to maybe understand what the program is doing?

This file contains encrypted data encrypted using my password manager app. My password manger gets the 'website url', 'ligin id' and 'password' and stores in a JSON object variable. Each credentials are encrypted using aes256 ctr mode and again the whole JSON object is converted to string and encrypted using aes256 ctr. User will be asked to enter two digit secret number + Master password (to decrypt each encrypted credentials) + Database password ( to decrypt stringified JSON and parse it).
User has to store database file in their google drive or local pc and upload them when any credentials are needed use them.
two digit secret number (this number is used as counter in aes256 ctr mode)
I wan't to earn money online by building this password manger app. I want to make it trustworthy and hack proof.

does assembler stuff like cmp / jump comparisons always compare against eax?
here, I would expect it to be something like:
'Jump if var_4h is less than or equal to eax' which is true.
but it seems to be working the other way aound
'Jump if eax is less than or equal to var_4h'
which is false, and continues going to the next line
magic falcon
depends on architecture and syntax of that asm implementation- It's been a few years, but IIRC many asm syntax refs have compare and jump commands for literals, pointers, and registers
rigid tapir
yeah its just a bit confusing since its the exact opposite of how the mov command works
magic falcon
RISC is less likely to have that, pretty sure AT&T syntax and MIPS both support multiple typesp
Move commands also vary between different implementations - some are src, dst, others are dst, src
rigid tapir
yeah the AT&T is src,dst
but the compare statement is also flipped round so maybe i'm not understanding something
magic falcon
usually cmp sets a reference register for the next jump instruction. I'd have to go back to old notes for the breakdown of the ref register
i know there are other conditions you can set the conditional jump to, but i don't know them off hand

onyx merlin
Unless you are using cygwin, windows has no shebang support. However, when you install python, it add as file association for . py files. If you put just the name of your script on the command line, or double click it in windows explorer, then it will run through python.

Hello, i wanted to ask about the malware analysis room.Do i need to know first how to program before going there ? and if yes is C++ good for starting because i'm trying to learn it.

python2
Python2 still has its place, as discussed
Don't knock it until you've tried writing a BoF in Python3
true pumice
Someone recently tried to code a BoF script in python3
tulip sail
It's possible. Just a pain in the rear end with the encoding
true pumice
They tried so hard to get it to work and I was like.. use python2 and they instantly found it easier
It's still useful 
surreal bronze
Yep, I guess python2 can be useful at times for things python3 isnt yet really compatible with like as you said BoF, but I find it way harder to program in 2

I find vim too complicated, but i'm sure it must be very efficient for people who know how to use it all
tulip sail
Incredibly so
brazen eagle
Don't knock it until you've tried writing a BoF in Python3
Can confirm it's a pain. sys.out.buffer.write or something like that
tulip sail
Oof, that'd do it for writing
Doing it over a network is worse though -- even with a raw socket you need to encode it just right
brazen eagle
I was stuck on the first BOF for Theseus because of python3
:(
You can't send raw Bytes over a socket?
brazen eagle
Those things must be buffered as well...
tulip sail
You can, but because of how Python3 handles encoding, they need to be specifically encoded as bytes
brazen eagle
Right that's what I thought
tulip sail
You can't just throw a string with \x characters in it into the socket
brazen eagle
And if you aren't typing your things properly you're doing it wrong!
tulip sail
It's some stupid encoding method as well iirc. From memory utf-8 doesn't cut it 😆

Latin-1 doesn't either

welp I started off looking for a simple way to look at old followers on twitter so I can clean up my feed a bit and ended up knee-deep in Twitter API v2. Really cool stuff and they make it dead simple with some code snippets, e.g.
# grab list of 100 most recently followed account for a particular user and pretty print json
curl https://api.twitter.com/2/users/<numericalID>/following?max_results=100 -H "Authorization: Bearer $TOKEN" | jq -r "." | tee pretty_printed.txt
https://developer.twitter.com/en/docs/twitter-api/users/lookup/introduction
gray ledge
What would you say a good place to start would be when trying to learn how to use APIs in python through requests
for example, the meaning of what droogy sent
sharp coral
honestly if you google any major API + 'python' you are bound to turn up loads of documentation, for example there are code examples for the Twitter API in python as documented here https://documenter.getpostman.com/view/9956214/T1LMiT5U
magic falcon
first step: understand how RESTful APIs accept requests and the forms data can be returned as. second step: proof of concept with curl and wget. third step: use HTTP request library for programming language of choice

Until I know it depends on how are you gonna use the data scrapped, and what are you gonna do with that

fair lion
what makes golang special over other programming languages?
hollow tangle
```go
package main
import (
"encoding/base64"
"fmt"
)
func main() {
...
It's because base64.StdEncoding.DecodeString returns a []byte but Encoded_string is a string https://golang.org/pkg/encoding/base64/#Encoding.DecodeString since you are using := for assignment it will try to shadow Encoded_string as a []byte inside the for loop and then go out of scope I would recommend just making two variables one holding your decoded string (or []byte since that's what base64 returns) at the return and one holding the encoded string
vernal vigil
Gotcha

It's not the best but use this as reference

neon shadow
Hello, New to the channel. I was wondering what would be a great program language to start learning to build some foundation in cyber security? Some say C some say Python etc.
magic falcon
Depends on your learning goals, and what you want to get out
C is better to learn system internals, python is faster to get something usable
magic falcon
Python abstracts out a lot of the harder concepts of C. There are pros and cons to each language
neon shadow
Ok great I will learn both.
magic falcon
Don't learn both at the same time if you are new to programming
that is a great way to confuse yourself
neon shadow
OK haha!
vague loom
There are some great resources that are pinned check them out
mystic nimbus
best would be to identify what you want to do with the programming language first, then you can identify which one to use
magic falcon
Pick a language until you know the basics of programming really well
then you can branch out and not end up horribly confused

@onyx meadow
def traingle():
for sides in range(3):
baraa.forward(100)
baraa.right(360/3)
# baraa.color("red")
traingle()
This part of your code does draw a triangle
The reason your other function doesn't work is because:
if i %3 == 1 :
return "green"
This returns your function at the first iteration because 1 % 3 == 1, it then returns a value that is never used.
You're also not using the color parameter anywhere in that function so it's redundant
It also doesn't draw anything in the for-loop.
It just sets the color.
def triangle(color):
for i in range(3):
if i % 3 == 0:
baraa.color("red")
baraa.forward(100)
baraa.right(360/3)
elif i % 3 == 1 :
baraa.color("green")
baraa.forward(100)
baraa.right(360/3)
else:
baraa.color(color)
baraa.forward(100)
baraa.right(360/3)
Now you're running into a DRY problem, where you're repeating baraa.forward(100); baraa.right(360/3)
So move the forward/rights under the conditional and let that just handle the setting of the color.
So you end up with:
def triangle(color):
for i in range(3):
if i % 3 == 0:
baraa.color("red")
elif i % 3 == 1 :
baraa.color("green")
else:
baraa.color(color)
baraa.forward(100)
baraa.right(360/3)
Not sure what the purpose of the program is but I would do this:
def triangle(color):
for i in range(3):
baraa.color(color)
baraa.forward(100)
baraa.right(360/3)
if var == 0:
triangle("red")
elif var == 1:
triangle("green")
I assumed he was trying to make a triangle with three different colored edges
distant shard
He said the return functions were for colors so I assumed he thought that they would somehow set them.
I could be wrong of course.
true pumice
If they do want three different coloured sides, I think the whole i % 3 if statement voids the use of the for loop
true pumice
def Triangle():
colours = ['Red', 'Blue', 'Green']
for colour in colours:
baraa.color(color)
baraa.forward(100)
baraa.right(360/3)
Unless the i % 3 has a specific purpose
