Nytro Posted July 30, 2017 Report Share Posted July 30, 2017 Koadic Koadic, or COM Command & Control, is a Windows post-exploitation rootkit similar to other penetration testing tools such as Meterpreter and Powershell Empire. The major difference is that Koadic does most of its operations using Windows Script Host (a.k.a. JScript/VBScript), with compatibility in the core to support a default installation of Windows 2000 with no service packs (and potentially even versions of NT4) all the way through Windows 10. It is possible to serve payloads completely in memory from stage 0 to beyond, as well as use cryptographically secure communications over SSL and TLS (depending on what the victim OS has enabled). Koadic also attempts to be compatible with both Python 2 and Python 3. Demo Hooks a zombie Elevates integrity (UAC Bypass) Dumps SAM/SECURITY hive for passwords Scans local network for open SMB Pivots to another machine Stagers Stagers hook target zombies and allow you to use implants. Module Description stager/js/mshta serves payloads in memory using MSHTA.exe HTML Applications stager/js/regsvr serves payloads in memory using regsvr32.exe COM+ scriptlets stager/js/rundll32_js serves payloads in memory using rundll32.exe stager/js/disk serves payloads using files on disk Implants Implants start jobs on zombies. Module Description implant/elevate/bypassuac_eventvwr Uses enigma0x3's eventvwr.exe exploit to bypass UAC on Windows 7, 8, and 10. implant/elevate/bypassuac_sdclt Uses enigma0x3's sdclt.exe exploit to bypass UAC on Windows 10. implant/fun/zombie Maxes volume and opens The Cranberries YouTube in a hidden window. implant/fun/voice Plays a message over text-to-speech. implant/gather/clipboard Retrieves the current content of the user clipboard. implant/gather/hashdump_sam Retrieves hashed passwords from the SAM hive. implant/gather/hashdump_dc Domain controller hashes from the NTDS.dit file. implant/inject/mimikatz_dynwrapx Injects a reflective-loaded DLL to run powerkatz.dll (using Dynamic Wrapper X). implant/inject/mimikatz_dotnet2js Injects a reflective-loaded DLL to run powerkatz.dll (@tirannido DotNetToJS). implant/inject/shellcode_excel Runs arbitrary shellcode payload (if Excel is installed). implant/manage/enable_rdesktop Enables remote desktop on the target. implant/manage/exec_cmd Run an arbitrary command on the target, and optionally receive the output. implant/pivot/stage_wmi Hook a zombie on another machine using WMI. implant/pivot/exec_psexec Run a command on another machine using psexec from sysinternals. implant/scan/tcp Uses HTTP to scan open TCP ports on the target zombie LAN. implant/utils/download_file Downloads a file from the target zombie. implant/utils/upload_file Uploads a file from the listening server to the target zombies.
