Why people recommend it

Each mark is one comment

  • Works well with LLM and MCP workflows

    “"ghidra -> ask LLM to reason about ghidra decompilation" is very effective on all but the most highly obfuscated binaries.”

    Comment from 15 Apr 2026 in “Cybersecurity Looks Like Proof of Work Now”

    “I would also suggest spending a few minutes to set up an mCP server with ghidra once you've learned the basics”

    Comment from 16 Feb 2026 in “Ghidra by NSA”

    “It's been pretty good with a Ghidra MCP at signature scanning for extremely niche undocumented software.”

    Comment from 31 May 2026 in “Microsoft degrades functionality of perpetually-licensed offline products”

What people warn about

Each mark is one comment

  • Slow, laggy UI and performance

    “Ghidra's most painful limitation was extremely slow time with Go Lang”

    Comment from 22 Feb 2026 in “We hid backdoors in ~40MB binaries and asked AI + Ghidra to find them”

    “The Ghidra UI is noticeably laggy to perform basic operations even with tiny binaries”

    Comment from 17 Feb 2026 in “Ghidra by NSA”

    “I'm not super happy with the design (I feel like it's built to be slow…)”

    Comment from 9 Apr 2026 in “I Ported Mac OS X to the Nintendo Wii”
  • Poor results on some binaries

    “These results are terrible, false positives and false negatives. Useless”

    Comment from 22 Feb 2026 in “We hid backdoors in ~40MB binaries and asked AI + Ghidra to find them”

    “At this point static analysis like IDA and Ghidra stopped working.”

    Comment from 11 Oct 2026 in “500B tokens later: Letting AI agents decompile a first-person shooter”

    “attempting to shoehorn them into ghidra produces not great results”
