Obfuscation

LDAP Obfuscation

Overview

PowerView.py can obfuscate LDAP queries and related parameters to vary observable patterns while preserving query intent. This feature transforms LDAP filters, distinguished names, and attribute lists using multiple techniques, making queries less predictable and harder to signature.

Enabling Obfuscation

Via CLI

Pass the --obfuscate flag when launching PowerView:

powerview range.net/lowpriv:Password123@192.168.86.192 --obfuscate

Via Web UI

Toggle the Obfuscate option in the Settings panel.

What Gets Obfuscated

Obfuscation is applied to three components of LDAP queries:

Component	Description
Filter	Transforms attribute names, operators, and values within LDAP search filters
DN	Mutates the search base distinguishedName
Attributes	Mutates the requested attribute list

Techniques Used

PowerView.py applies the following obfuscation techniques:

OID attribute encoding - Attribute names are replaced with their OID equivalents, with spacing and zero-padding variations
Random casing - Attribute names and values are randomly uppercased and lowercased
Numeric/SID zero-prepend - Numeric and SID values are prepended with leading zeros
Hex-encoding - Eligible values are hex-encoded where supported
Context-aware spacing - Whitespace is inserted in valid positions within filters and DNs
Equality to approximation operator substitution - The = operator is replaced with ~= (approximate match) where applicable
Wildcard expansion - Values are split with wildcard characters (e.g., admin becomes a*dmin)
ANR attribute randomization - Ambiguous Name Resolution attributes are randomly selected from the set of valid ANR attributes
DN hex escaping - Characters in distinguished names are hex-escaped with random casing
Attribute list OID aliasing - Requested attributes are replaced with OID aliases and randomly cased

Important Notes

Results returned by obfuscated queries are functionally equivalent to non-obfuscated queries. However, approximation operator substitution and wildcard expansion techniques can broaden the result set, potentially returning additional matches beyond what a standard query would produce.
Strict LDAP server configurations may reject heavily obfuscated queries. If you encounter errors or unexpected failures with obfuscation enabled, consider disabling it or testing against the target server incrementally.
