Open Source C Anti-Malware Software

YARA is a tool aimed at (but not limited to) helping malware researchers to identify and classify malware samples. With YARA you can create descriptions of malware families (or whatever you want to describe) based on textual or binary patterns. Each description, a.k.a rule, consists of a set of strings and a boolean expression which determines its logic. YARA is multi-platform, running on Windows, Linux and Mac OS X, and can be used through its command-line interface or from your own Python scripts with the yara-python extension. YARA-CI may be a useful addition to your toolbelt. This is GitHub application that provides continuous testing for your rules, helping you to identify common mistakes and false positives. If you plan to use YARA to scan compressed files (.zip, .tar, etc) you should take a look at yextend, a very helpful extension to YARA developed and open-sourced by Bayshore Networks.

Geo Firewall performs blocking of network traffic based on geography (geo IP), allows to add custom subnets, allows exceptions on ports for incoming traffic for specific geography, keeps visual and persistent logs, shows statistics, automatically updates geographical database.

readpe (formerly known as pev) is a multiplatform toolkit to work with PE (Portable Executable) binaries. Its main goal is to provide feature-rich tools for properly analyze binaries with a strong focus on suspicious ones.

tpe-lkm is a Linux kernel module implementing Trusted Path Execution, a security feature that denies users from executing programs that are not owned by root, or are writable. This closes the door on a whole category of exploits where a malicious user tries to execute his or her own code to hack the system. Since the module doesn't use any kind of ACLs, it works out of the box with no configuration. It isn't complicated to test or deploy to current production systems. The module also has a few other grsecurity-inspired features implemented as "extras".

Is your server running slowly? Clamav-sniffer could help - it scans for malware such as phishes and viruses and configures your firewall to block the cracker.

Anoubis is a Security Suite which implements a secured environment for applications. The core of the suite is an Application Firewall alongside with a Sandbox. Mechanisms to assure the authenticity of files, directories and applications are provided.

EaseFilter Folder Locker is a Windows file and folder protection solution built on the EaseFilter File Control, Encryption and Process Filter Driver SDK. It lets you lock, hide, and restrict access to files and folders in real time to prevent unauthorized access or modification.

Edit the Windows Registry from a Live CD to Remove Malware and fix problems that keeps your system from booting.

The EaseFilter Process Filter Driver SDK is a kernel-mode development kit designed to help developers monitor and control Windows process and thread activities. By intercepting process and thread operations at the kernel level, it enables the development of robust security applications that can prevent unauthorized or malicious processes from executing. With the Process Filter Driver, it allows you to prevent the untrusted executable binaries (malwares) from being launched, protect your data being damaged by the untrusted processes. It also enables your application to get the callback notification for the process/thread creation or termination, from the new process information you can get the parent process Id and thread Id of the new created process, you also can get the exact file name that is used to open the executable file and the command line that is used to execute the process if it is available.

This project is intended for generating a series of patches for the current version of QEMU to counter anti-detection and anti-debugging technics.

The EaseFilter Registry Filter Driver SDK is a powerful, kernel-mode development toolkit designed to help developers monitor, control, and protect Windows registry operations in real time. It enables the development of robust security, compliance, and system integrity solutions by intercepting and managing registry access before it reaches the Windows registry subsystem. The SDK allows your application to receive notifications before any registry operation is processed by the Windows Configuration Manager. By registering a RegistryCallback routine, your application can detect: Registry key creation, deletion, renaming Registry value changes Query operations
