BOFHound

BOFHound is an offline BloodHound ingestor and LDAP result parser compatible with TrustedSec's ldapsearch BOF and the Python adaptation, pyldapsearch.

By parsing log files generated by the aforementioned tools, BOFHound allows operators to utilize BloodHound's beloved interface while maintaining full control over the LDAP queries being run and the spped at which they are executed. This leaves room for operator discretion to account for potential honeypot accounts, expensive LDAP query thresholds and other detection mechanisms designed with the traditional, automated BloodHound collectors in mind.
