Koadic C3 COM Command & Control - JScript RAT 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. However, as Python 2 will be going out the door in the not-too-distant future, we recommend using Python 3 for the best experience. 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.

Merlin is a cross-platform post-exploitation HTTP/2 Command & Control server and agent written in golang. HTTP/2 is a newly ratified protocol documented under RFC 7540 that aims to solve some of the problems with HTTP/1.x and provide functionality to support current web application operations. HTTP/2 communications are multiplexed, bi-direction connections that do not end after one request and response. Additionally, HTTP/2 is a binary protocol that makes it more compact, easy to parse, and not human readable without the use of an interpreting tool. An HTTP/2 connection can be setup by upgrading a HTTP/1.x connection using the `Upgrade` header or during the negotiation of a TLS encrypted channel. Application-Layer Protocol Negotiation (ALPN) is a TLS 1.2 extension that is required to setup a HTTP/2 connection identified with the `h2` protocol string. TLS versions less than 1.2 are not equipped to negotiate a HTTP/2 connection. Oddly enough, the client will perform one final check to ensure that the server can speak HTTP/2 by sending the string PRISM. This reminds me of the NSA PRISM program.
