CredBaron

CredBaron is a Go port of CredMaster that uses residential proxy rotation instead of AWS API Gateway / FireProx. Every auth attempt can ride a different source IP, either from a proxy list or from a single rotating-endpoint URL.

Install

# prebuilt release
https://github.com/dejisec/credbaron/releases

# or install
go install github.com/dejisec/credbaron/cmd/credbaron@latest

# or build from source
git clone https://github.com/dejisec/credbaron
cd credbaron && make build
./credbaron plugins list

Docker:

docker build -t credbaron .
docker run --rm -v "$PWD:/work" -w /work credbaron spray --config config.json

How it works

You hand CredBaron a plugin name, a user list, a password list, and a proxy source. It spins up a worker pool (default 10) where each worker picks a fresh proxy URL from your source for every request. Each attempt retries up to 3 times with 2s backoff on transport errors, and the plugin classifies the response as success, failure, or potential. Before the pool spawns, CredBaron fires one pre-flight request through the proxy to confirm the target is reachable, so a dead proxy source surfaces immediately.

Successes, valid usernames, and the full console transcript all land in timestamped files under --output-dir. If you pass --resume <state.jsonl>, already-classified (user, password) pairs are skipped on the next run.

Quickstart

Confirm that your proxy is working:

./credbaron proxy check \
  --proxy-endpoint 'http://user:pass@gate.provider.com:7777' 
# or
./credbaron proxy check --proxy-file proxies.txt --count 5

Spray Microsoft Online (msol plugin):

./credbaron spray \
  --plugin msol \
  -u users.txt -p passwords.txt \
  --proxy-endpoint 'https://user:pass@gate.provider.com:7777' \
  --threads 20 \
  --jitter 10 --jitter-min 3 \
  --passwords-per-delay 1 --delay 180 \
  --color

With a proxy list file instead:

./credbaron spray \
  --plugin msol \
  -u users.txt -p passwords.txt \
  --proxy-file proxies.txt \
  --proxy-strategy random

Plugins

14 plugins ship with the binary. Run credbaron plugins list to view the current set.

• Microsoft / Azure AD: msol, msgraph, azvault, azuresso, o365enum
• Federated / SSO: adfs, okta, pingfed
• Exchange: owa, ews
• VPN: fortinetvpn
• Enumeration: gmailenum
• Generic: httpbrute httppost

Proxy sources

Two mutually-exclusive modes: --proxy-file <path> for a newline-separated list, or --proxy-endpoint <url> + optional --proxy-session-var <token> for a single gateway that rotates IPs per session. NTLM and PingFed plugins pin one proxy per credential attempt because those handshakes can't rotate mid-flight. --insecure-tls skips cert verification end-to-end (for self-signed OWA/EWS). See docs/proxies.md.

Timing

Four independent timing knobs, all optional, all compose:

• Jitter: random sleep before each attempt
• Batch: sleep every N attempts per worker
• Inter-password delay: sleep between password cycles
• Weekday warrior: only spray during business hours Mon–Fri

See docs/config.md for the full flag reference, --randomize, --stop-on-success, timeouts, UA rotation, and custom headers.

Output

Every run writes timestamped files under --output-dir DIR (default .): a -success.txt of raw user:pass, a -validusers.txt of confirmed usernames, a .log transcript, and an optional .jsonl event stream with --json-output. See docs/config.md for filenames, and event kinds.

Resume

--resume <path> writes every classified attempt to a JSONL checkpoint. On re-run with the same path, already-tested pairs are skipped. See docs/resume.md.

Notifications

Seven webhook backends, fire-and-forget with a 5-second timeout. See docs/notifications.md.

Config file

Everything on the CLI is also settable via JSON. CLI flags override config values. See docs/config.md for the full reference and configs/config.example.json for the complete shape.

./credbaron spray --config config.json

Subcommands

• credbaron spray: the main event. All flags: credbaron spray --help.
• credbaron plugins list: view registered plugin names.
• credbaron proxy check: fire N test requests through the configured proxy source and print the egress IP each returned. --count N (default 3), --target URL (default https://ipinfo.io/json).
