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.
Detects msiexec.exe executing from the Temp directory with suspicious command-line arguments (such as hidden windows) and spawning child processes like cmd.exe, tasklist.exe, or taskkill.exe. This behavior is often indicative of malicious installation scripts attempting to perform discovery or terminate security processes while remaining stealthy.
This rule detects instances where a process named 'wsc_updata.exe' executing from a Temp directory loads a library named 'wsc.dll'. This behavior is characteristic of DLL side-loading or DLL hijacking, where a malicious or potentially unwanted executable attempts to load a library from a user-writable directory to execute arbitrary code.
This rule detects potentially malicious activity associated with removable media (USB drives) by identifying two distinct patterns: first, the creation of an 'autorun.inf' file on a removable drive followed by the execution of a script or executable from that same drive shortly after. Second, it identifies executables appearing on removable media that are launched across multiple distinct hosts within a one-hour window, which may indicate worm-like spreading or mass-malware distribution via portable storage.
Detects the loading of reflective (memory-only) DLLs within the chrome.exe process address space. This activity is indicative of memory-based exploit chains, such as those that corrupt WebAssembly module metadata to facilitate arbitrary code execution following a sandbox escape.
Detects the creation of a scheduled task containing 'EdgeCore_AutoUpdate' in the command line using either schtasks.exe or Register-ScheduledTask. This pattern is often indicative of persistence mechanisms attempting to masquerade as legitimate update services.
This rule monitors for potential persistence and malicious activity by aggregating three distinct detection signals: COM hijacking attempts via the InprocServer32 registry key, the creation of scheduled tasks using specific suspicious naming conventions, and the identification of named mutexes indicative of specific malware presence.
Detects attempts to inhibit system recovery by deleting volume shadow copies or modifying backup/boot recovery configurations. The rule monitors for the execution of vssadmin, wmic, wbadmin, and bcdedit with flags known to facilitate system recovery inhibition, often observed as a precursor to ransomware activity.
Detects anomalous command-line arguments and process injection behaviors associated with the Sogou IME protocol handler (biz_helper.exe). The rule monitors for malicious argument injection (e.g., embedded scripts, URLs pointing to non-Sogou domains) and correlates these events with suspicious child processes or network activity, consistent with techniques observed in the GRAYRABBIT / UNC3569 threat activity.
Detects known malicious file hashes for GRAYRABBIT delivery chain components: trojanized 7zp.dll loader, encrypted PE loader shellcode, and GRAYRABBIT backdoor core.dll, gated on PE structural validity and filesize
Detects UNC3569/GRAYRABBIT shellcode combining call/pop self-location, PEB InLoadOrderModuleList walk, and the specific XOR-then-ROR8 export-name hashing loop observed in the GRAYRABBIT loader chain, requiring multiple distinctive elements together to reduce false positives on generic shellcode idioms

Detects reconnaissance commands (e.g., file listing, directory enumeration) executed as child processes of the JFrog Artifactory service. This behavior is often associated with the exploitation of Artifactory plugins or misconfigured endpoints that allow arbitrary code execution, enabling an attacker to perform discovery actions.
Detects Rust-compiled executables exhibiting C2-capable characteristics consistent with backdoors dropped on compromised JFrog Artifactory servers

This rule detects the creation of a scheduled task named 'GlobalProtectVPNUpdate' using schtasks.exe, which has been identified as a technique used to facilitate the execution of malicious payloads masquerading as legitimate GlobalProtect VPN components. It also monitors for the subsequent execution of 'GlobalProtect.exe' when initiated by Windows background services like taskeng.exe or svchost.exe, which is indicative of persistence and unauthorized code execution.
Detects the suspicious execution of cmd.exe with piped stdio handles (indicative of a reverse shell) initiated by non-standard parent processes associated with the GRAYRABBIT malware, correlated with an immediate outbound network connection from the same process.

Detects the execution of an unsigned 7z.exe that loads an unsigned 7z.dll from a public, user-writable directory (C:\Users\Public\Documents). The rule specifically looks for the creation of the DLL shortly before it is loaded, indicating potential DLL side-loading to bypass security controls using a renamed or modified archive utility.
