There is a lot of hype with LLMs and their capabilities.

Long time ago I wrote three detailed blog posts about how to write shellcodes for Windows (x86 – 32 bits).

Introduction First step in the process of penetration testing is “Information gathering”, the phase where it is useful to get as much information about the target(s) as possible.

Some time ago I detailed PHP Object Injection vulnerabilities and this post will get into details of Java deserialization vulnerabilities.

I had the opportunity to present NetRipper at BlackHat Asia Arsenal 2018 and it was amazing.

The purpose of NetRipper is to capture functions that encrypt or decrypt data and send them through the network.

The previous two blog posts describe how a Stack Based Buffer Overflow vulnerability works on x86 (32 bits) Windows.

In the first part of this article, we discussed about the basics that we need to have in order to properly understand this type of vulnerability.

I wrote this article in Romanian, in 2014, and I decided to translate it, because it is a very detailed introduction in the exploitation of a “Stack Based Buffer Overflow” on x86 (32 bits) Windows.

I decided to start a blog.
