HoneypotBuster

Microsoft PowerShell module designed for red teams that can be used to find honeypots and honeytokens in the network or at the host.

CodeExecution

Execute code on a target machine using Import-Module.

HoneypotBuster is a tool designed to spot Honey Tokens, Honey Bread Crumbs, and Honey Pots used by common Distributed Deception vendors. This tool will help spot the following deception techniques:

1. Kerberoasting Service Accounts Honey Tokens

Just like the one described in the ADSecurity article by Sean Metcalf, this tricks attackers to scan for Domain Users with assigned SPN (Service Principal Name) and {adminCount = 1} LDAP Attribute flag. So when you try to request TGS for that user, you’ll be exposed as Kerberoasting attempt. TGS definition: A ticket granting server (TGS) is a logical key distribution centre (KDC) component that is used by the Kerberos protocol as a trusted third party.

2. Fake Computer Accounts Honey Pots

Creating many domain computer objects with no actual devices associated to them will result in confusion to an attacker trying to study the network. Any attempt to perform lateral movement into these fake objects will lead to exposure of the attacker.

3. Fake Credentials Manager Credentials Breadcrumbs

Many deception vendors are injecting fake credentials into the “Credentials Manager”. These credentials will also be revealed using tools such as Mimikatz. Although they aren’t real, attackers might confuse them with authentic credentials and use them.

4. Fake Domain Admins Accounts Honey Tokens

Creating several domain admins and their credentials who have never been active is bad policy. These Honey Tokens lure attackers to try brute-forcing domain admin credentials. Once someone tries to authenticate to this user, an alarm will be triggered, and the attacker will be revealed. Microsoft ATA uses this method.

5. Fake Mapped Drives Breadcrumbs

Many malicious automated scripts and worms are spreading via SMB Shares, especially if they’re mapped as Network Drive Share. This tool will try to correlate some of the data collected before to identify any mapped drive related to a specific Honey Pot server.

6. DNS Records Manipulation HoneyPots

One of the methods deception vendors use to detect fake endpoints is registering their DNS records towards the Honey Pot Server. They will then be able to point the attacker directly to their honeypot instead of actual endpoints.
