Hi Every Body , This Is 0xMrRobot
From Time To Time , I Get Into Some CTFs To Practice More And Develop My Skills In Reverse Engineering..
It Pleases Me To Get Into ASCWG Finals CTF 2023 And Solve 1 OF 4 Reverse Challenges In This Competition And This Is My Write Up For This Challenge… ❤
1- Ghostly Kisses
Challenge Name : Ghostly Kisses

206 RETURN_VALUEThis Code Is For Python Code , So Let’s Check It And Divide It To Sections To Write The Original Python Code Like In The (TCP/IP Reverse Engineering Challenge Write Up In My Blog )
After Long Time From Reading This Byte Code And Translate It Into Python Code With Assistance From AI , This Is The Original Script Code :
import hashlib
def weirdo(ch):
data = hashlib.md5(ch.encode()).hexdigest()
for i in range(1000):
if i % 2 == 0:
data = hashlib.sha1(data.encode()).hexdigest()
elif i % 7 == 0:
data = hashlib.sha256(data.encode()).hexdigest()
elif i % 3 == 0:
data = hashlib.sha512(data.encode()).hexdigest()
elif i % 11 == 0:
data = hashlib.md5(data.encode()).hexdigest()
elif i % 5 == 0:
data = hashlib.sha384(data.encode()).hexdigest()
return hashlib.sha512(data.encode()).hexdigest()
with open('Flag.txt', 'r') as f:
flag = f.read().strip()
Hashes = []
for char in flag:
hsh = weirdo(char)
Hashes.append(hsh)
with open('Flag', 'w') as w:
for i in Hashes:
w.write(i + '\n')And As We See In This Script , We Have Some Points We Must Conclude After Analyzing This Code :
weirdo Function:
def weirdo(ch):
data = hashlib.md5(ch.encode()).hexdigest()
for i in range(1000):
if i % 2 == 0:
data = hashlib.sha1(data.encode()).hexdigest()
elif i % 7 == 0:
data = hashlib.sha256(data.encode()).hexdigest()
elif i % 3 == 0:
data = hashlib.sha512(data.encode()).hexdigest()
elif i % 11 == 0:
data = hashlib.md5(data.encode()).hexdigest()
elif i % 5 == 0:
data = hashlib.sha384(data.encode()).hexdigest()
return hashlib.sha512(data.encode()).hexdigest()This function takes a single character (ch) as input, converts it to its MD5 hash, and then iteratively hashes it in a loop. Depending on the current iteration (i), different hash algorithms are applied. After 1000 iterations, the final result is hashed using SHA-512, and the resulting hash is returned.
File Reading:
with open('Flag.txt', 'r') as f:
flag = f.read().strip()This block reads the contents of the ‘Flag.txt’ file, strips any leading/trailing whitespaces, and stores it in the variable flag. This likely represents the input data that will be processed by the weirdo function.
Hash Calculation Loop:
Hashes = []
for char in flag:
hsh = weirdo(char)
Hashes.append(hsh)For each character in the flag, the weirdo function is called, and the resulting hash is appended to the list Hashes.
File Writing:
with open('Flag', 'w') as w:
for i in Hashes:
w.write(i + '\n')Finally, the hashes obtained from the weirdo function are written to a file named 'Flag', with each hash on a new line.
And We Have Now The Encrypted (Hashed Flag) With The Challenge :

Modified Script :
import hashlib
def weirdo(ch):
data = hashlib.md5(ch.encode()).hexdigest()
for i in range(1000):
if i % 2 == 0:
data = hashlib.sha1(data.encode()).hexdigest()
elif i % 7 == 0:
data = hashlib.sha256(data.encode()).hexdigest()
elif i % 3 == 0:
data = hashlib.sha512(data.encode()).hexdigest()
elif i % 11 == 0:
data = hashlib.md5(data.encode()).hexdigest()
elif i % 5 == 0:
data = hashlib.sha384(data.encode()).hexdigest()
return hashlib.sha512(data.encode()).hexdigest()
characters = ['A', 'S', 'C', 'W', 'G']
for char in characters:
hsh = weirdo(char)
print(f'Hash for {char}: {hsh}')Let’s Run :
Now We Ensures That , The Given Hashed Values Is The Flag Values , So Now We Only Need To BruteForse The Chars Which Match The Given Hashed Values , So We Need To Run This Function On All Chars And Match The Result (Hashed Value) With The Given One , And If It Matched Then Print The Char Which Achieve This Matching ..
So I Wrote This Script To Do This Operation :
import hashlib
def weirdo(ch):
data = hashlib.md5(ch.encode()).hexdigest()
for i in range(1000):
if i % 2 == 0:
data = hashlib.sha1(data.encode()).hexdigest()
elif i % 7 == 0:
data = hashlib.sha256(data.encode()).hexdigest()
elif i % 3 == 0:
data = hashlib.sha512(data.encode()).hexdigest()
elif i % 11 == 0:
data = hashlib.md5(data.encode()).hexdigest()
elif i % 5 == 0:
data = hashlib.sha384(data.encode()).hexdigest()
return hashlib.sha512(data.encode()).hexdigest()
