Detects .NET DLLs containing hardcoded Azure Storage Account credentials, such as access keys or SAS tokens. This technique was observed in the Axis Communications plugin for Autodesk Revit, where it could have enabled a supply chain attack.
Detects PowerShell being used to modify Group Policy Objects (GPOs) to disable Windows Defender security features. This technique is used by threat actors like Storm-2603 for defense evasion.
Detects a variety of HTTP exploitation attempts associated with the RondoDox botnet campaign. This campaign uses a 'shotgun' approach, targeting numerous vulnerabilities in internet-facing devices like routers, DVRs, and web servers.
Detects command execution characteristic of the AntSword web shell's virtual terminal feature. This is identified by a web server process spawning a child process with a specific command-line structure, often involving `cmd.exe` and echoing unique start and end tags (`stag`/`etag`).
Detects DLL side-loading activity consistent with the Mustang Panda Claimloader malware. This rule looks for a process loading a DLL from its own directory, a common side-loading pattern. It specifically targets IOCs from the Claimloader campaign (e.g., decoy executable metadata and malicious DLL names) or a more generic pattern where an executable in a suspicious location loads a DLL.
Detects attempts to exploit a SQL injection vulnerability (CVE-2025-57819) in FreePBX via a malicious GET request to '/admin/ajax.php'. Attackers leverage this to achieve remote code execution by inserting a malicious cron job.
Detects a process launched by the Windows Task Scheduler from a non-standard directory that immediately loads a DLL from the same directory. This is a strong indicator of DLL Sideloading for persistence, as seen in campaigns by groups like ToddyCat.
Detects Chaos C++ ransomware payloads based on known file hashes and unique embedded strings from the malware.
Detects suspicious child processes spawned by the GoAnywhere MFT Tomcat service. This behavior is consistent with post-exploitation activity following a successful remote code execution exploit of CVE-2025-10035, as observed in campaigns by the threat actor Storm-1175.
MAL Bat Dropper
YARA
Detects a specific multi-stage batch file dropper identified by its hash. This malware uses PowerShell, VBScript, and multiple layers of obfuscation (Base64, XOR, Gzip) to deliver its payload.
