Crash BOTS and SCRAPERS using BOMBS💣. Delivered for free, directly by Cloudflare!

⭐ Live demo HERE - *use with a scanning tool*

---

Are you fed up with bots and scrapers getting a free pass on your website? Want to fight back??

*This is the ser of the classic
dd if=/dev/zero bs=1G count=10 | gzip
trick, also described in
idiallo.com/blog/zipbomb-protection.*

Quick start

Then, in another terminal:

🧨 Every path behaves the same way: /, /wp-login.php, /.env, etc.

---

Deploy your own

You need Node.js 18+ and a Cloudflare account with a domain linked. **Setup takes only a
few minutes.**

1. Pick your bomb hostname

In Cloudflare, open your zone → DNS, and add a sundomain record for the bomb
host:

| Type | Name | Content | Proxy |
| ------ | ------ | --------- | ---------------------- |
| AAAA | bomb | 100:: | Proxied (orange cloud) |

2. Point the Worker at it

Uncomment and edit the routes block in wrangler.toml:

3. (Optional/Skip) Regenerate the bomb

Only rebuild it if you want a different
size. See Configuration.

4. Ship it

Then confirm it from outside:

🔥 Done! 🔥

Configuration

*Skippable in most cases, just know you can change bomb size here*
There is almost nothing to configure. The only knob is the bomb
size, set when you (re)generate the blob with make bomb:

| What | Where | Default |
| --------------------- | -------------------------- | -------------------------------- |
| Decompressed size | GIB in the Makefile | 10 = 10 GiB |
| Compression level | gzip -9 in the Makefile| -9 (max) |
| Served Content-Type | src/index.ts | text/html; charset=utf-8 |

For example, make bomb GIB=1 gives a 1 GiB bomb (~1 MB on the wire), gentler
and cheaper, good for testing.

FAQ

🔷 Why does curl show only 10 MB, not 10 GB?

curl does not decompress responses unless you pass --compressed. Without it you
see the raw ~10 MB on the wire. With it, curl inflates the gzip and you get the
full 10 GiB. Most bots decompress automatically, like curl --compressed.

🔷 Won't this cost me bandwidth?

Each hit sends ~10 MB out of Cloudflare. That is cheap, but not free, and it scales
with how much traffic you attract. Shrink the bomb (see
Configuration) if egress is a concern.

🔷 Will it crash a real browser / my own monitoring?

It can. Clients that auto-decompress (most scrapers and bots) try to inflate it and exhaust their own memory. That's the point. If you want to spare one path (e.g. a health check), add a
short-circuit at the top of fetch in src/index.ts:

🔷 I have a working bomb, now what?

Now you leave it as hidden link/href where ever you might get bots crawling.
Fake pagination code, fake price fetch, redirect to bomb after X failed auth. Since every URI also gets bombed (bomb.example.com/ANYTHING-HERE), you can really get creative with it!

🔷 How do I view bomb stats

In the Cloudflare dashboard, search for "Worker", select "Workers & Pages", click on your bomb worker, then select "Metrics" in the upper tabs.

control, and only against traffic you are entitled to disrupt. Serving a
decompression bomb to clients you do not control may be illegal in your
jurisdiction. You are solely responsible for how and where you deploy it.
