Detects the creation of .bat files within the Windows Startup folder. Adversaries often use this technique to achieve persistence by ensuring a script executes automatically upon user login.
Detects AutoIT executables running from a Temp directory that take an .ini file as a command-line argument. This pattern is commonly used by AutoIT-based malware loaders or droppers to ingest configuration files containing obfuscated code or C2 communication parameters.
Detects the execution of PowerShell with suspicious command-line flags often associated with malicious scripts (e.g., hidden windows, no profile, bypassed execution policies) when the script is located in the Windows Temporary directory.
Detects instances of the Windows Character Map utility (charmap.exe) loading graphics-related libraries such as System.Drawing.dll or gdiplus.dll. These modules are typically not required by charmap.exe and their loading is a common indicator of process injection for the purpose of capturing the screen or desktop interface.
Detects instances where PowerShell.exe spawns the .NET C# compiler (csc.exe) with command-line arguments referencing a '.cmdline' file. This pattern is commonly used by adversaries to compile malicious code in-memory, bypassing traditional disk-based file scanning.
This rule detects incoming email messages containing .zip attachments with filenames that mimic financial documents (e.g., NFe, DANFE, invoice-related keywords) combined with numerical strings. This naming pattern is commonly associated with phishing campaigns attempting to deliver malicious archives.
Detects unauthorized processes attempting to access sensitive Mozilla Firefox profile files such as cookies.sqlite, places.sqlite, and permissions.sqlite. These files contain sensitive information including cookies, history, and permission settings. Access by processes other than the legitimate Firefox executable may indicate credential theft, data exfiltration, or reconnaissance activities.
Detects suspicious processes (named UpdateAssistant.exe, AppUpdateHelper.exe, or SysMaintenance.exe) executing from specific file system paths and initiating network connections to known suspicious IP addresses (5.230.249.49, 40.124.169.27) on non-standard ports (27015, 27017). The rule correlates process execution from specific suspicious directories with network activity to identify potential command-and-control communication.
Detects the execution of suspected Hidden VNC (HVNC) backdoor components that demonstrate behaviors consistent with banking credential theft, specifically targeting keystroke logging APIs. The rule monitors for specific process names executing from suspicious directories often used for persistence.
Detects bulk read operations on AWS Secrets Manager or similar cloud secret stores where the accessed resources contain keywords related to cryptocurrency custody, private keys, or wallet material. This pattern is indicative of unauthorized exfiltration attempts by threat actors such as Slim Spider targeting digital asset infrastructure.
