    PyRDP: Remote Desktop Protocol Monster-in-the-Middle (MITM) and Library
    https://github.com/GoSecure/pyrdp

    Target Audience: Offense and Malware Researchers

    Short Abstract:
    PyRDP is a Remote Desktop Protocol (RDP) monster-in-the-middle (MITM) tool and library useful in intrusion testing and malware research. Its out of the box offensive capabilities can be divided in three broad categories: client-side, MITM-side and server-side. On the client-side PyRDP can actively steal any clipboard activity, crawl mapped drives and collect all keystrokes. On the MITM-side PyRDP records everything on the wire in several formats (logs, json events), allows the attacker to take control of an active session and performs a pixel perfect recording of the RDP screen. On the server-side, on-logon PowerShell or cmd injection can be performed when a legitimate client connects.

    Over the last year, we implemented several features that we are going to uncover in this brand-new demo lab workshop: a headless mode that allows deployment on systems with less resources or without an X11 stack, a fully transparent layer-2 deployment capability leveraging IP_TRANSPARENT sockets, a brand new Windows Graphical Device Interface (GDI) implementation and the ability to convert recorded sessions into MP4 videos.

    On the malware research side, PyRDP can be used as part of a fully interactive honeypot. It can be placed in front of a Windows RDP server to intercept malicious sessions. It can replace the credentials provided in the connection sequence with working credentials to accelerate compromise and malicious behavior collection. It also saves a visual and textual recording of each RDP session, which is useful for investigation or to generate IOCs. Additionally, PyRDP saves a copy of the files that are transferred via the drive redirection feature, allowing it to collect malicious payloads.

    Detailed Explanation of Tool:
    It’s an extensive reimplementation of the RDP spec in Python with an added MITM layer where we abused the RDP protocol to the full extent of its capacity. Gory details are the blogs and the GitHub’s README listed above.

    It is licensed under the GPLv3.

    Short Developer Bio:
    Olivier Bilodeau is leading the Cybersecurity Research team at GoSecure. With more than 10 years of infosec experience, he enjoys luring malware operators into his traps, writing tools for malware research, reverse-engineering all-the-things and vulnerability research. Passionate communicator, Olivier has spoken at several conferences like BlackHat, Defcon, Botconf, SecTor, Derbycon, HackFest and more. Invested in his community, he co-organizes MontréHack, a monthly workshop focused on hands-on CTF problem solving, and NorthSec, a large non-profit conference and CTF based in Montreal.

    Alexandre Beaulieu is a security researcher working for GoSecure. His area of expertise is reverse engineering, binary exploitation and tool development. His previous experience as a software developer covers a broad spectrum of topics ranging from low-level systems and binary protocols to web applications. Prior to joining the research team, Alexandre spent time as an Ethical Hacker honing his offensive security skills. His areas of interest include binary analysis, compiler theory and systems programming. Alexandre gives back to the Montréal infosec community by volunteering his time, contributing workshops and designing application security challenges for events like MontréHack and REcon.
