A BBOT scan in real-time - visualization with VivaGraphJS
# stable version

Upgrading from 2.x? BBOT 3.0 contains breaking changes to the CLI, presets, modules, events, and Python API. See the 2.x → 3.0 Migration Guide (source) before upgrading.
Speed tip: BBOT's DNS resolver (blastdns) spins up multiple threads per resolver in
/etc/resolv.conf. Adding more unfiltered resolvers dramatically speeds up scans. See the sample resolv.conf and Tips and Tricks for details.
Passive API sources plus a recursive DNS brute-force with target-specific subdomain mutations.
# find subdomains of evilcorp.com
bbot -t evilcorp.com -p subdomain-enum
# passive sources only
bbot -t evilcorp.com -p subdomain-enum -rf passive
subdomain-enum.ymldescription: Enumerate subdomains via APIs, brute-force
flags:
# enable every module with the subdomain-enum flag
- subdomain-enum
output_modules:
# output unique subdomains to TXT file
- subdomains
config:

threads: 25
brute_threads: 1000
# put your API keys here
# modules:

BBOT consistently finds 20-50% more subdomains than other tools. The bigger the domain, the bigger the difference. To learn how this is possible, see How It Works.
