MoreNew technique added: "Named Pipes / SMB," featuring two code snippets for demonstration purposes. The first snippet uses .NET (C#) to showcase Named Pipes usage, while the second employs WinAPI with Delphi. Both examples aim to illustrate the application of Named Pipes in different programming environments.

This lightweight C# application serves as a demonstration of how simple it is to interactively access a remote system's shell via named pipes using the SMB protocol. It includes an optional encryption layer leveraging AES GCM, utilizing a shared passphrase between both the server and the client.

New evasion technique and snippet added for file extension manipulation using the Right-to-Left Override (RLO) character (U+202E). Malicious actors exploit this Unicode control character in file names to alter the visual display of extensions, making dangerous executables appear harmless to users. For example, invoice.pdf
becomes invoiceexe.pdf
by strategically placing the RLO character. This deception aims to trick users into unwittingly executing potentially harmful files.

Continuing our enlightening "Malware Retrospective" series, we delve back into the depths of cybersecurity history. Following our thorough examination of Beast RAT, the early 2000s' formidable malware, we now turn our focus to another significant entity of that period, SubSeven. Conceived by the mysterious figure, Mobman, this Remote Access Trojan, also known as Sub7, remains an iconic marker in the evolution of digital threats. Join us as we explore its intriguing chronicles, offering both a retrospective glance and vital lessons for today's cybersecurity landscape.

The release of version "3.0 Final" signifies the culmination of this project. I will not be adding any further features; the objective of this PoC was to demonstrate the creation of a reliable and secure C2 utilizing FTP(S). You're encouraged to develop your own version with tailored functionalities. As an exercise, you might consider implementing multi-threading tasking to prevent the application from hanging during long-duration tasks.
I will, however, continue to provide support for the project in terms of addressing potential bugs or opportunities for optimization.

SharpFtpC2 is a small, experimental project aimed at exploring the possibility of using FTP(S) for relaying commands and responses between two remote computers. It employs the FTP protocol as a makeshift tunnel through which the computers, both acting as clients connected to an FTP server, can communicate. A simple session management scheme is used to keep track of the exchange of requests and responses.

An alternative version of the code snippet, crafted in Delphi, has been introduced for the "C2 via FTP(S)" technique. This variant expertly demonstrates the employment of the Windows API's from Windows Internet (WinInet) library.

A freshly added Unprotect C# code snippet elucidates the implementation of the "C2 via FTP(S)" technique. This example adeptly showcases the utilisation of the .NET Framework's WebRequest and FtpWebRequest classes, illustrating the steps to effectively execute tasks, handle requests, and manage responses through FTP (File Transfer Protocol).

In this inaugural instalment of the Malware Retrospective series, we take a trip down memory lane to revisit the Beast RAT, a notorious Windows RAT (Remote Access Trojan) developed by the elusive “Tataye.” This groundbreaking malware left an indelible mark on a whole generation of enthusiasts, including myself, who were captivated by its ingenuity and influence the whole scene back in it’s time.

A new version of the unprotect portal has been released with updates including:
FeaturedAPI is a new feature that allows for the mapping of common Microsoft Windows API's used by specific evasion techniques, with the ability to consult the most commonly used API's for each technique and their associated caution level (Low, Medium, High) as well as access to official and unofficial documentation.
The team is also making progress on the sample scanner to match scanned samples to potential fitting techniques.

DLest is a Microsoft Windows application that helps developers and malware analysts analyze and manipulate exported functions in Portable Executable (PE) files, especially DLLs. It allows you to enumerate exported functions using various methods and supports the analysis of memory-loaded modules in real time. It also has the ability to dump a reconstructed version of any module for further analysis. DLest is fully multithreaded and efficient for processing large numbers of PE files. It is useful for developers and malware analysts and streamlines their tasks.
