This rule detects attempts to perform process injection techniques (such as creating remote threads or opening processes) targeting the 'ctfmon.exe' process, where the initiating process is not 'ctfmon.exe' itself. This behavior is indicative of potential malicious activity such as reflective code loading or the execution of malware like SparkRAT, which may use this legitimate Windows process to mask its activity.
This rule detects potentially malicious process injection activities (CreateRemoteThreadApiCall, ProcessInjection, OpenProcessApiCall) targeting the Volume Shadow Copy Service process (vssvc.exe). It monitors for interactions originating from processes other than legitimate system processes (svchost.exe, services.exe) or vssadmin.exe, which is commonly associated with Volume Shadow Copy manipulation. Such activity often indicates attempts by malware or attackers to inject code into a critical system process to gain persistence, escalate privileges, or evade detection.
This rule detects cross-process injection techniques, such as OpenProcess, CreateRemoteThread, and memory modifications, specifically targeting 'svchost.exe' instances that do not appear to be hosting critical Windows services. By filtering out known critical services (e.g., RpcSs, DcomLaunch), the rule flags suspicious attempts to inject code into legitimate service host processes to mask malicious activity.
Detects the GoCaracal lightweight implant performing process injection by identifying combinations of remote process memory allocation (VirtualAllocRemoteApiCall), memory writing (WriteProcessMemoryRemoteApiCall), and remote thread creation (CreateRemoteThreadApiCall) associated with specific suspicious filenames. It also monitors command-line activity for injection-related flags.
This rule detects attempts to perform process injection techniques (such as creating remote threads or opening processes) targeting the 'ctfmon.exe' process, where the initiating process is not 'ctfmon.exe' itself. This behavior is indicative of potential malicious activity such as reflective code loading or the execution of malware like SparkRAT, which may use this legitimate Windows process to mask its activity.
Detects the loading of compression libraries (such as lzma.dll or 7z.dll) by ERAAgent.exe followed by suspicious process or thread activity (e.g., remote thread creation, memory allocation). This pattern is often associated with the staging and execution of malicious payloads in memory.

By filtering out known critical services (e.g., RpcSs, DcomLaunch), the rule flags suspicious attempts to inject code into legitimate service host processes to mask malicious activity.
This rule detects a multi-stage attack chain characteristic of the WordlistLoader/Amatera malware. It identifies the sequential occurrence of module unhooking (via CreateToolhelp32Snapshot), ETW bypass (via AddVectoredExceptionHandler), and remote process injection (via WriteProcessMemory, CreateRemoteThread, etc.) originating from the same process within a 15-minute window.
This rule detects potentially malicious memory manipulation and thread execution activity originating from the ERAAgent.exe process. It specifically identifies when ERAAgent.exe calls VirtualProtect or VirtualAlloc to set memory as PAGE_EXECUTE_READWRITE, followed shortly by a CreateThread or CreateRemoteThread operation. This behavior is indicative of process injection or reflective code loading, where an executable image is manually mapped into memory and executed, bypassing traditional file-based detection.

Detects instances where the Windows spooler driver (winspool.drv) is loaded by a process that subsequently performs suspicious memory operations typical of process injection (e.g., CreateRemoteThreadApiCall, WriteToProcessMemory, ProcessInjection) within a 5-minute window.
This rule detects potentially malicious behavior where a process accesses environment variables containing 'TOKIO_WORKER_THREADS' (often associated with Rust applications or specific runtime environments) and simultaneously performs sensitive process operations like 'GetSystemInfo' or 'CreateThread'. This pattern may indicate an attempt by an adversary to perform discovery or process injection within a target application environment.
