Detects the execution of WScript via a scheduled task named 'MicrosoftEdgeUpdateTaskCore'. This pattern is often used to masquerade malicious activity by using the name of a legitimate Microsoft Edge update process to execute scripts silently (using //B //Nologo).
Detects instances where WScript or CScript (Windows Script Host) initiate child processes like PowerShell or Conhost, specifically when those child processes contain command line arguments referencing environment variable access pattern 'GetEnvironmentVariable' for 'Kv' keys. This pattern is commonly associated with retrieving stored configuration or sensitive data using script-based wrappers to execute logic.
This rule detects potentially malicious behavior where common scripting processes such as PowerShell, WScript, or CScript interact with sensitive memory-related APIs (e.g., VirtualProtect, GetProcAddress, LoadLibrary) or monitor modules (amsi.dll, clr.dll). This pattern is often indicative of reflective loading, memory injection, or attempts to bypass security controls like AMSI.
Detects outbound HTTP POST requests to the Telegram Bot API (/sendPhoto) that contain sensitive system information, including host credentials (port, login, password) and Shodan host data. This behavior is indicative of an information-stealing malware attempting to exfiltrate captured credentials via a Telegram bot.
Detects instances where PowerShell is executed with encoded commands, seemingly spawned by a process masquerading as or related to the Microsoft Edge Update Task. The rule specifically monitors for process chains involving 'conhost.exe' with '--headless' arguments and subsequent PowerShell execution containing encoded commands, often associated with obfuscated activity.
Detects the use of PowerShell cmdlets and parameters to perform system, hardware, and external drive discovery. This includes querying volume information, disk/partition details, and checking for removable or specific bus-type media (USB, SD, MMC), which is commonly associated with reconnaissance activities by an adversary.
Detects instances where PowerShell is executed with encoded commands, seemingly spawned by a process masquerading as or related to the Microsoft Edge Update Task. The rule specifically monitors for process chains involving 'conhost.exe' with '--headless' arguments and subsequent PowerShell execution containing encoded commands, often associated with obfuscated activity.
Detects the execution of a process named 'hzwzucr_widsisa.exe' located within the 'AppData' directory. The rule further specifies that this process must be spawned by a command line initiated from 'C:\ProgramData\doxc' or by 'cmd.exe', indicating potentially suspicious activity common in malware deployment patterns.
Detects the creation of .iso or .zip files on Windows user directories (Desktop/Downloads) or with suspicious filenames potentially associated with phishing delivery methods.
Detects the creation of a specific JSON file named 'uploaded_files.json' within a 'SmartUploader' directory by PowerShell. This behavior may indicate an automated process, script, or actor staging data for exfiltration or managing uploaded content via PowerShell.
