Detects the creation, renaming, or modification of a file named 'FitnessMonitor.exe' within the Windows Startup folder. This behavior is indicative of an attempt to establish persistence by ensuring the executable runs automatically upon user login.
Detects the addition of a 'DailyFitnessTracker' registry entry into the 'HKCU\Software\Microsoft\Windows\CurrentVersion\Run' key. This is a common persistence technique where programs are configured to execute automatically upon user login, utilizing either 'reg.exe' or PowerShell 'New-ItemProperty' to modify the registry.
Detects the creation or renaming of files within the '\ProgramData\doxc' directory, and correlates this with the execution of 'mklink /H' commands that point to that directory. This behavior is indicative of an adversary establishing persistence or hiding files by creating hard links.
Detects the execution of command-line tools (cmd.exe or wscript.exe) spawned by Windows Explorer (explorer.exe) where the command line contains references to .lnk files or specific batch filenames (doxc.bat, config.bat). This behavior is often indicative of malicious shortcut files used to trigger secondary stage payloads.
This rule detects the execution of processes where the command line contains suspicious obfuscated substrings. These substrings, which include segments like 'inASISFHfo', 'geASISFHutarvs', 'scASISFHuren', 'fiASISFHu_lsz', 'afASISFHile', or 'ruASISFHunf', are characteristic of command-line obfuscation techniques designed to bypass security monitoring by concealing the true intent of the command.
Detects the unknown or suspicious process 'doxc' (or 'doxc.exe') executing common Windows system administration utilities ('wmic.exe', 'fsutil.exe', 'cmd.exe') or command-line arguments typically used for reconnaissance and system information discovery, such as listing logical disks or volume information.
Detects the creation or modification of a file named 'uploaded_files.json' within a directory containing 'SmartUploader' under the user's AppData path. This pattern is often indicative of data staging or local file tracking activity by potentially malicious software.
Detects the execution of 'htspnew.exe' by 'ubp.exe' where both executables are located in the same parent directory. This pattern may indicate suspicious process lineage or potential malware activity.
Detects the creation or modification of a file named 'uploaded_files.json' within a directory containing 'SmartUploader' under the user's AppData path. This pattern is often indicative of data staging or local file tracking activity by potentially malicious software.
This rule detects the execution of cmd.exe or powershell.exe where the command line arguments involve the deletion or renaming of specific file names potentially associated with unauthorized activities or malware components. It looks for common command-line utilities (del, ren) being used by command shells on specific files that may indicate artifact cleanup or staging.
Detects the execution of 'htspnew.exe' by 'ubp.exe' where both executables are located in the same parent directory. This pattern may indicate suspicious process lineage or potential malware activity.
Detects common Windows command-line utilities used for internal network reconnaissance, including ARP cache queries, NetBIOS enumeration, SMB share/session discovery, and subnet ping sweeps. These techniques are frequently employed by adversaries for lateral movement preparation and internal network mapping.
Detects the use of PowerShell to enumerate storage devices (USB, disk, partition information) and perform file operations such as copying or logging, potentially indicating malicious data collection from removable media or external drives.
Detects execution of command lines containing suspicious, potentially obfuscated substrings that do not correspond to standard Windows utilities. The use of custom delimiters like 'ASISFH' within common command strings suggests an attempt to bypass signature-based detection.
Detects a scenario where a process (cmd.exe) executing a file named 'config.bat' subsequently launches another instance of cmd.exe to delete files with a '.lnk' extension. This behavior is indicative of cleanup activities after potential malicious script execution.
This rule detects the execution of processes identified as 'DriverInstaller.exe' or files with known malicious SHA256 hashes associated with suspicious driver installation activity. The rule excludes legitimate system processes like msiexec.exe and trustedinstaller.exe, which are typically responsible for authorized software and driver installations.
Detects the execution of PowerShell with encoded commands in headless mode, associated with the Microsoft Edge Update Task (MicrosoftEdgeUpdateTaskUserS-1-5-24). This pattern is indicative of potential malicious activity where legitimate update tasks are abused to run obfuscated scripts.
Detects the creation of files within the 'SystemFolder32' or 'System Folder32' directory under the user's Local AppData path, a known behavioral pattern for payload staging used by the Transparent Tribe threat actor.
This rule detects the use of PowerShell to download a specific payload associated with the RustyShade malware from a Backblaze B2 cloud storage bucket. It monitors command lines containing 'wget' or 'Invoke-WebRequest' targeting 'f005.backblazeb2.com' and files named 'DriverInstaller.zip'.
Detects instances where the process 'UBPUpdater.Exe' spawns a process or command line utilizing 'UBPPatch.Psh'. The rule highlights that 'UBPPatch.Psh' is masquerading as a non-executable PowerShell script while likely operating as a malicious binary or PowerShell executable.
Detects the creation of scheduled tasks using schtasks.exe or PowerShell that masquerade as legitimate Microsoft Edge or OneDrive update tasks. This behavior is associated with APT36 (Transparent Tribe) and their use of modular malware to establish persistence.
