Black Hat Go

Go Programming For Hackers and Pentesters

Tom Steele, Chris Patten, Dan Kottmann

Tom Steele, Chris Patten, and Dan Kottmann show how to use Go's networking primitives, concurrency model, and cross-compilation to write offensive tooling that runs almost anywhere.

A Bug Hunter's Diary

A Guided Tour Through the Wilds of Software Security

Tobias Klein

Tobias Klein walks through seven real vulnerabilities he found and exploited, in the form of personal lab notes, what he tried, what failed, and what eventually shipped to vendors.

Read this if

Offensive practitioners who already know Python (or Bash) and want a compiled-language alternative for tools that need to run as a single binary on locked-down endpoints. Go's cross-compilation and tiny runtime make it the right choice for many implant-style tools.
Vulnerability researchers and aspiring bug hunters who want to feel what real research actually feels like. Klein's lab-notes format makes failure visible, which is the part the typical write-up genre hides.

Skip this if

Beginners with no programming background. The book assumes Go familiarity at the syntax level; for the language itself, read The Go Programming Language (Donovan/Kernighan) first.
Readers wanting modern web/API bug hunting. The book is binary-focused (browser, kernel, audio drivers) and from 2011; for current bug bounty workflow, read Real-World Bug Hunting and Bug Bounty Bootcamp instead.

Key takeaways

  • Go binaries cross-compile to Windows, Linux, macOS, and ARM with no toolchain pain; for offensive tools that need to land on a target, Go saves hours.
  • Concurrency in Go is simple enough that scanners, brute forcers, and watchdog tools become trivial to write; the book's networking chapters lean on this.
  • Modern offensive tooling (Cobalt Strike alternatives, Mythic agents, Sliver) is increasingly Go-native; reading this book is reading the language those projects share.
  • Real vulnerability research is mostly hypothesis-and-failure; Klein's diary format teaches the resilience the field demands.
  • Sample selection (which target, which feature, which bug class) is the highest-leverage choice; the book makes this explicit in a way most write-ups skip.
  • Disclosure tradecraft (vendor coordination, patch tracking, advisory writing) is part of the work; the chapters on it are the calmest treatment in print.

How they compare

Black Hat Go and A Bug Hunter's Diary are both rated 4/5 in our catalog. Pick by topic preference and reading style rather than by rating.

Both books target intermediate-level readers, so the choice is about topic, not difficulty.

Black Hat Go and A Bug Hunter's Diary both cover Offensive, so reading them in sequence reinforces the same material from different angles.
