Detects potential misuse of the WinGet configuration feature, where remote Desired State Configuration (DSC) YAML files are retrieved using masqueraded file extensions (e.g., .jpg or .txt) or suspicious outbound connections on port 8443, which may indicate an adversary attempting to hide malicious configurations or bypass network filtering.
Detects specific samples of the Rmrlx information stealer by identifying unique file artifacts, mutex names (e.g., Global\EVOLUTION), and debugging/staged files commonly associated with its execution environment, including samples exhibiting IP-checking evasion techniques.
This rule monitors outbound network traffic for the inclusion of a Windows-style hostname pattern (e.g., 'DESKTOP-XXXXXX'), which is often used by stealer malware or RATs to identify victim machines during C2 communication. It explicitly excludes Microsoft licensing traffic to reduce false positives.
This rule detects internal hosts initiating outbound SSH connections to known public tunneling services (e.g., pinggy.io). Attackers frequently use these services to bypass network firewalls and create persistent reverse SSH tunnels for remote command-and-control access. The detection logic focuses on the identification of SSH protocol traffic headers combined with specific domain targeting or repetitive connection behavior.
Detects the use of the Windows 'tasklist' utility or command execution via 'cmd.exe' when the command line includes strings associated with common debugging tools (e.g., windbg, x64dbg). This behavior may indicate an adversary checking for the presence of analysis tools or attempting to manipulate running processes, which is often associated with debugger evasion or malicious environment reconnaissance.
Detects the execution of 'rundll32.exe' or 'dllhost.exe' with command-line arguments typically associated with loading Control Panel items (.cpl files). This behavior is often used by adversaries to proxy execution of malicious payloads or bypass security controls by leveraging legitimate Windows binaries.
Detects the creation of a file named 'Normaliz.dll' within an 'AppData\Roaming\Traiolx Custom Utils' directory. The rule matches a known malicious MD5 hash or a specific folder path structure, which is indicative of potential DLL sideloading or persistence mechanisms using an abnormally located DLL.
Detects execution of PowerShell with bypassed execution policy used to download or copy files from remote locations using curl.exe and Copy-Item. This pattern is commonly associated with file staging or retrieving malicious payloads from external URLs, including specific paths.
This rule detects the execution of the Windows FTP client (ftp.exe) using a command script file (via the -s: parameter). It monitors for process creation of ftp.exe with this flag, excluding known legitimate paths. It then correlates this with any child processes initiated by the FTP client to identify potential data exfiltration or automated file transfers.
This rule detects suspicious PowerShell activity including the use of PowerShell to invoke 'curl.exe' for data transfer or the creation of randomly named executables (6-10 characters) within the 'AppData\Local\Temp' directory, which is a common indicator of file staging or malware execution.
