Coeus

Coeus is an ADSI based Situational Awareness toolkit for domain environments with modularity in mind. Allows for the enumeration of users/groups/computers as well as some common misconfigurations including roasting (AS-REP, kerber) and delegation (Constrained, Unconstrained, RCBD) attacks.

Usage

Coeus is an interactive console app, meaning executing the binary drops users into a prompt. Use commands to view all available commands like so:

To get help for any command, use the help util:

Features

• Enumerate users, groups (and group memberships), and computers on a domain
• Returns information on the domain and forest including domain
• Returns information on the RootDSE
• Searches for accounts with descriptions
• Returns "interesting accounts" (based ona string array in Models/Data.cs)
• Query object properties
• Return domain password policies
• Returns machine accounts with SPNs assigned and their respective SPNs
• Searches for potentially AS-REP/Kerberoastable accounts
• Searcher for machines potentially vulnerable to delegation attacks (constrained, unconstrained, resource based, coming soon)
• Query GPOs
• Query object ACL

Compile Instructions

Open .sln in Visual Studio and build

To-Do

• Give option to set/change SearchScope
• Users
  • no passwd req'd
• ObjPropery
  • parse SID/GUID
• LAPSSweep
• RoastHunter
  • if machine w/ SPN is found, attempt to determine enc type (msDS-SupportedEncryptionTypes) and return that
  • use Coeus to locate potentially kerberoastable machines and fetch neccesary info to pass to SnipeRoast AtlasUtil
• ACL Enum
  • https://www.specterops.io/assets/resources/an_ace_up_the_sleeve.pdf
  • takes obj as param
  • allow for the specifying of Identity Reference
• GPO Enum
  • fetch all
  • all properties
  • specific properties
  • return names
  • correctly return byte[] entries (objGUID)
• DCSync
  • search for DS-Replication-Get-Changes, DS-Replication-Get-Changes-All, DS-Replication-Get-Changes-In-Filtered-Set
• Misc
  • create method to convert and return SID/GIUD entries in extensions
• Authenticate
  • Allow for operator to authenticate into a domain as to not drop Coeus to disk
