weak rsa
This challenge provides the encrypted ciphertext and public key with a weak factor . The goal is to get the flag in the message .

this is a quick and concise information about the weakness

can derive from the reading that if the p and q values are smaller primes, can break the RSA algorithm! Which should be what we need to do here

Ganapati has made this awesome RSA multi attacks tool that checks for all possible vulnerabilities in the public key and even does the attacks . like in my case i gave it the public key and ciphertext and it gave me the flag .
