The post is well-regarded in the security community for its detailed breakdown of exploiting a vulnerability in how antivirus engines handle (often seen as .rar files). Key technical highlights from that "solid" post include:

: Successfully writing a Return-Oriented Programming (ROP) chain and shellcode into the window buffer to achieve remote code execution.

: Implementing basic Rar1 and Rar3 encoders to gain control over read-write primitives.

It sounds like you're referencing a specific deep-dive or technical analysis, likely related to the blog post by researcher Landave.

: Using specific techniques to manipulate the memory layout.
