CrimsonEDR is an open-source project engineered to identify specific malware patterns, offering a tool for honing skills in circumventing Endpoint Detection and Response (EDR). By leveraging diverse detection methods, it empowers users to deepen their understanding of security evasion tactics. Features Detection | Description —|— Direct Syscall | Detects the usage of direct system calls, often employed by malware to bypass traditional API hooks. NTDLL Unhooking | Identifies attempts to unhook functions within the NTDLL library, a common evasion technique. AMSI Patch | Detects modifications to the Anti-Malware Scan Interface (AMSI) through byte-level analysis. ETW Patch | Detects byte-level alterations to Event Tracing for Windows (ETW), commonly manipulated by malware to evade detection. PE Stomping | Identifies instances of PE (Portable Executable) stomping. Reflective PE Loading | Detects the reflective loading of PE files, a technique employed by malware to avoid static analysis. Unbacked Thread Origin | Identifies threads originating from unbacked memory regions, often indicative of malicious activity. Unbacked Thread Start Address | Detects threads with start addresses pointing to unbacked memory, a potential sign of code injection. API hooking | Places a hook on the NtWriteVirtualMemory function to monitor memory modifications. Custom Pattern Search | Allows users to search for specific patterns provided in a JSON file, facilitating the identification of known…Read More
