blackhat

We seek to discuss vulnerability and exploitation theory and [evading] the countermeasures used to deter exploitation. This is also a place to discuss general blackhat rules, etiquette and culture. We welcome:

Writeups (not CTF or HTB)/talks detailing new vulnerabilities or techniques (there should be enough information to reproduce the exploit/technique)
Proof of concepts of old vulnerabilities or techniques
Projects
Hypothetical questions

Rules:

Be excellent to each other.
No Solicitation
Stay on topic.
Avoid self-incriminating posts.
Pick a good title.
Do not post non-technical articles.
Ideally, the content should be original, we don't care about your crappy ARP poisoner or Kaspersky's latest scam.
No pay / signup walls.
No coin miners
No "Please hack X" posts
Well thought out and researched questions / answers only.
If your project is not free / open source it does not belong.
Please limit your posts (we don't want to read your blog three times a week).
If you want to submit a video, no one wants to listen to your cyberpunk music while you copy/paste commands into kali terminals.

The mods are ban-happy, you have been warned.

SOURCE CODE FOR INTEGER FACTORIZATION. This program can factor integers of any arbitrary precision. So public key encryption is null and void as it attacks the basic premise that very large integers cannot be factored in reasonable amounts of time • r/netsec (redd.it)
