A tool to find a company (target) infrastructure, files, and apps on the top cloud providers (Amazon, Google, Microsoft, DigitalOcean, Alibaba, Vultr, Linode). The outcome is useful for bug bounty hunters, red teamers, and penetration testers alike.

At a glance
While working on HunterSuite, and as part of the job, we are always thinking of something we can automate to make black-box security testing easier. We discussed this idea of creating a multiple platform cloud brute-force hunter.mainly to find open buckets, apps, and databases hosted on the clouds and possibly app behind proxy servers.
Here is the list issues we found with previous tools:
- separated wordlists
- lack of proper concurrency
- lack of supporting all major cloud providers
- require authentication or keys or cloud CLI access
- outdated endpoints and regions
- Incorrect file storage detection
- lack support for proxies (useful for bypassing region restrictions)
- lack support for user agent randomization (useful for bypassing rare restrictions)
- hard to use, poorly configured
- Cloud detection (IPINFO API)
- Supports all major providers
- Black-Box (unauthenticated)
- Fast (concurrent)
- Modular and easily customizable
- Cross Platform (windows, linux, mac)
- User-Agent Randomization
- Proxy Randomization (HTTP, Socks5)
Supported Cloud Providers
Just download the latest release for your operation system and follow the usage.
To make the best use of this tool, you have to understand how to configure it correctly. When you open your downloaded version, there is a config folder, and there is a config.YAML file in there.
It looks like this
providers: ["amazon","alibaba","amazon","microsoft","digitalocean","linode","vultr","google"] # supported providers environments: [ "test", "dev", "prod", "stage" , "staging" , "bak" ] # used for mutations proxytype: "http" # socks5 / http ipinfo: "" # IPINFO.io API KEY
For IPINFO API, you can register and get a free key at IPINFO, the environments used to generate URLs, such as test-keyword.target.region and test.keyword.target.region, etc.
We provided some wordlist out of the box, but it’s better to customize and minimize your wordlists (based on your recon) before executing the tool.
After setting up your API key, you are ready to use CloudBrute.

Default: 80 -T --timeout timeout per request in seconds. Default: 10 -p --proxy use proxy list -a --randomagent user agent randomization -D --debug show debug logs. Default: false -q --quite suppress all output. Default: false -m --mode storage or app. Default: storage -o --output Output file. Default: out.txt -C --configFolder Config path. Default: config
CloudBrute -d target.com -k target -m storage -t 80 -T 10 -w "./data/storage_small.txt"
please note -k keyword used to generate URLs, so if you want the full domain to be part of mutation, you have used it for both domain (-d) and keyword (-k) arguments
If a cloud provider not detected or want force searching on a specific provider, you can use -c option.
CloudBrute -d target.com -k keyword -m storage -t 80 -T 10 -w -c amazon -o target_output.txt
- Clone the repo
- go build -o CloudBrute main.go

How to make the best out of this tool?
Read the usage.
I get errors; what should I do?
Make sure you read the usage correctly, and if you think you found a bug open an issue.
When I use proxies, I get too many errors, or it’s too slow?
It’s because you use public proxies, use private and higher quality proxies. You can use ProxyFor to verify the good proxies with your chosen provider.
too fast or too slow ?
change -T (timeout) option to get best results for your run.
