Detects suspicious DLL loads or file drops performed by security product processes (avp.exe, MsMpEng.exe) from directories outside of standard, trusted vendor paths. It specifically flags unsigned or invalidly signed DLLs, which is indicative of DLL sideloading techniques used to abuse security software workflows for potential privilege escalation.
Detects the loading of the somkernl.dll module by 360speedld.exe or SoftupNotify.exe, or the execution of these binaries. These files are associated with 360 Safe/360 Security software components, and this rule monitors for their specific activity patterns, which may be used to identify software presence or potential process hollowing/masquerading attempts involving these legitimate components.
Detects indicators of the 'ShieldCrash' proof-of-concept (CVE-2026-69414 exploit bypass) on Windows systems. The rule monitors for specific malicious file activity, module loading, and the presence of decoy archive files associated with the PoC, which are used to achieve arbitrary file read as SYSTEM.
This rule detects suspicious command executions (e.g., whoami, downloadstring, iex, registry modifications) initiated by processes associated with the CrowdStrike Falcon agent. It also correlates these executions with the loading of unsigned or unverifiable DLLs by the same Falcon processes within a 5-minute window, which may indicate attempts to tamper with or masquerade as the security agent.
Detects the loading of WMI-related DLLs (wbemcomn.dll, wbemprox.dll) by processes that are commonly abused to proxy execution (LOLBins) such as certutil, mshta, or office applications. This behavior is often associated with WMI-based persistence or execution techniques.
This rule detects potential COM hijacking of the CLSID InprocServer32 registry keys or unauthorized loading/creation of the 'EhStoreShell.dll' file. These behaviors are common indicators of persistence mechanisms or DLL side-loading where attackers redirect legitimate system calls to malicious code.
Detects the loading of the 'user32.dll' library into a process named 'firefox.exe' where the process is either unsigned or executing from a suspicious location like 'ProgramData'. This pattern is consistent with the behavior of BabylonRAT, which masquerades as the Firefox browser to perform keylogging by hooking system APIs.
This rule detects instances of a process named 'firefox.exe' that is executing from a directory other than the standard 'Mozilla Firefox' program folders. When this masquerading process loads critical system DLLs like 'kernel32.dll' or 'ntdll.dll', it flags potential dynamic API resolution activity commonly associated with BabylonRAT and similar malware that attempts to hide its capabilities by resolving system functions at runtime.
Detects suspicious DLL loads or file drops performed by security product processes (avp.exe, MsMpEng.exe) from directories outside of standard, trusted vendor paths. It specifically flags unsigned or invalidly signed DLLs, which is indicative of DLL sideloading techniques used to abuse security software workflows for potential privilege escalation.
Detects instances where 'ERAAgent.exe', part of the ESET Remote Administrator agent, loads the 'dpapi.dll' library from a location outside of standard Windows System directories (System32 or SysWOW64). Furthermore, the rule flags this behavior if the loaded 'dpapi.dll' file is either unsigned or contains an untrusted digital signature, which may indicate a malicious DLL side-loading or masquerading attempt to access protected system credentials.
Detects instances where the ESET Remote Administrator Agent (ERAAgent.exe) terminates shortly after loading the Data Protection API service (dpapisvc.dll). This pattern may indicate an attempt to interact with or disrupt DPAPI services, potentially to facilitate credential dumping or sensitive data access.
Detects potential exploitation of a CrowdStrike Falcon remediation process vulnerability ('FalconFlank'). The rule identifies either direct execution of the PoC binary or the suspicious combination of a CrowdStrike remediation process loading an unsigned or untrusted DLL from a user-writable path followed by the same process spawning a command shell in the SYSTEM context within 15 minutes.
Detects when the PostgreSQL service process (postgres.exe/postgres/postmaster) loads a shared library (.dll or .so) from a non-standard, user-writable directory (e.g., Temp, AppData, /tmp). This behavior is indicative of potential exploitation of vulnerabilities like CVE-2026-6471, where attackers attempt to load malicious plugins via unvalidated logical decoding plugin paths.
This rule detects potential reflective code injection or in-memory loading (fileless) where a DLL or PE image is loaded by mshta.exe or powershell.exe, but the module load event lacks a valid file path on disk (or indicates a device path). This behavior is often associated with the execution of malicious payloads such as the Amatera loader, where payloads are executed directly in memory to evade file-based security detections.
Detects the reflective or in-memory loading of the AsyncRAT DLL (Veukuzmw.dll) into the memory space of the legitimate Windows process charmap.exe, characterized by a lack of corresponding disk activity or suspicious process command-line arguments.
This rule monitors for indicators of compromise (IOCs) associated with a specific AutoIT-based malware delivery chain. It tracks the execution and presence of specific malicious file names and SHA256 hashes, as well as network connections to a identified command-and-control (C2) infrastructure IP address (158.51.122.136). The detection spans file creation, process execution, image loading, and network communication events to identify the multi-stage attack lifecycle.

Detects the loading or execution of 'core.dll' from non-standard system directories by common Windows proxy execution binaries (rundll32.exe, regsvr32.exe, cmd.exe, powershell.exe), which is a common indicator of DLL side-loading or malicious library hijacking.
This rule detects potential COM hijacking of the CLSID InprocServer32 registry keys or unauthorized loading/creation of the 'EhStoreShell.dll' file. These behaviors are common indicators of persistence mechanisms or DLL side-loading where attackers redirect legitimate system calls to malicious code.
