The (!FALSE) Pattern | Huntress

SOAPHound uses an LDAP query pattern that undergoes transformation during LDAP optimization, resulting in a distinctive (!FALSE) signature in Event 1644 logs. This transformation provides a detection method for identifying SOAPHound activity that security teams may not be familiar with. The finding highlights the importance of understanding how LDAP query optimization affects logging and detection signatures.

Why it matters: Defenders monitoring for SOAPHound reconnaissance need to recognize this transformed pattern in Event 1644 logs to detect LDAP attacks that would otherwise appear as normal directory queries.

threat intel

The (!FALSE) Pattern | Huntress

SOAPHound uses an LDAP query pattern that evades standard detection by transforming into a (!FALSE) signature through LDAP optimization, a behavior not typically logged in Windows Event 1644. Security teams can identify this activity by recognizing this uncommon query structure in LDAP logs.

Why it matters: Defenders need awareness of this transformation pattern to detect SOAPHound reconnaissance activity, which queries Active Directory to map domain structure and identify targets for lateral movement or data exfiltration.
