### AI overview

This tutorial examines methods for bypassing an active-protection EDR, including avoiding suspicious RWX memory changes, unhooking API calls, and using direct syscall instructions. It also introduces SharpBlock and accompanying code.

### Source excerpt

A 2 part series on creating a basic EDR detection system and then a bypass implementation. In part 2 I introduce SharpBlock, a method of bypassing EDR's. The post Lets Create An EDR... And Bypass It! Part 2 appeared first on Ethical Chaos.

### AI overview

Part one explains how a basic EDR detects malicious files and behavior through signature detection, kernel-level file system filters, sandboxing, and dynamic analysis. It also introduces sandbox bypass concepts involving analysis time limits and disrupted control flow.
