This rule detects the creation of a scheduled task intended to run an executable named 'wsc_updata.exe' from a temporary directory, or identifies svchost.exe initiating a process from that location. Such behavior is indicative of potential persistence mechanisms where malicious actors attempt to run code from unauthorized or writable directories under the context of system processes or scheduled tasks.
Detects Mimikatz binary or in-memory module used for credential harvesting following PaperCut RCE exploitation
Detects the execution of common discovery commands like 'whoami' combined with system information gathering commands (tasklist, ver, uname) when initiated by an application named 'pc-app.exe'. This pattern is frequently observed during the reconnaissance phase of an attack.
Detects the execution of Certipy, an open-source tool used for enumerating and exploiting Active Directory Certificate Services (AD CS). The rule monitors for common command-line arguments used during various stages of AD CS attack lifecycle, including finding misconfigurations, requesting certificates, relaying, and template exploitation.
Detects the execution of the Rubeus.exe utility with command-line arguments indicative of Kerberos-related credential harvesting and abuse, such as Kerberoasting, AS-REP Roasting, and Pass-the-Ticket attacks.
Detects the execution of BloodHound/SharpHound reconnaissance tools and the presence of their generated output files (ZIP or JSON format) on a host. This rule monitors both the process creation events associated with the tool's execution and file creation events indicative of data staging or collection output.
Detects the use of obfuscated PowerShell commands that utilize .NET [Convert]::FromBase64String combined with character replacement string manipulation, a common technique to hide malicious payloads from simple static analysis.
Detects obfuscated PowerShell commands that utilize XOR operations combined with byte array manipulation and common file writing methods. This pattern is frequently used by malicious scripts to deobfuscate and drop payloads to disk.
Detects the use of PowerShell's 'WriteAllBytes' method to write a file to the user's Local AppData Temp directory, immediately followed by the creation of a known or suspicious executable file in that same location. This pattern is commonly indicative of a stage in a fileless-style malware attack or automated payload delivery.
Detects the execution of PowerShell with common obfuscation flags (-W Hidden, -nop, -nol) that attempt to load and execute a script directly from the user's local Temp directory. The detection specifically monitors for processes launched by command interpreters like cmd.exe or batch files, which is a common indicator of a malware dropper or stager.
Detects the creation or execution of suspicious .bat files within the Windows Startup folder, often coupled with command-line arguments involving .ini files. This behavior is indicative of persistence mechanisms where adversaries leverage the startup folder to ensure malicious scripts run upon user logon.
Detects suspicious execution of files located in the AppData Local Temp directory initiated by PowerShell or using PowerShell-specific hidden window arguments. This behavior is commonly associated with dropper scripts or malware staging execution from a user's temporary folder.
Detects the creation or modification of a file with a specific randomized name ('nloemfbihmhm') in the temporary directory, followed by the execution of a process identified as AutoIt from the same directory.
This rule detects the process 'charmap.exe' establishing an outbound network connection to a known AsyncRAT command-and-control (C2) IP address and port. This behavior is indicative of process injection where the legitimate Windows Character Map utility is utilized as a host process for malicious AsyncRAT payload execution.
Detects network connections to command-and-control infrastructure associated with the JeetBot/Twitch Enhanced Viewer malicious browser extension. The rule triggers on connections to known malicious domains or IPs, as well as specific API endpoints on ambiguous domains that are used for exfiltrating Twitch OAuth tokens.

Detects network connections to command-and-control infrastructure associated with the JeetBot/Twitch Enhanced Viewer malicious browser extension. The rule triggers on connections to known malicious domains or IPs, as well as specific API endpoints on ambiguous domains that are used for exfiltrating Twitch OAuth tokens.
Detects network connections to known JeetBot infrastructure domains and IP addresses. The rule specifically identifies potential exfiltration of Twitch OAuth tokens via URL parameters or interaction with known token-collection proxy endpoints, which are associated with the JeetBot/Twitch Enhanced Viewer credential harvesting campaign.
Detects network connections to command-and-control infrastructure associated with the JeetBot/Twitch Enhanced Viewer malicious browser extension. The rule triggers on connections to known malicious domains or IPs, as well as specific API endpoints on ambiguous domains that are used for exfiltrating Twitch OAuth tokens.
Detects network connections to command-and-control infrastructure associated with the JeetBot/Twitch Enhanced Viewer malicious browser extension. The rule triggers on connections to known malicious domains or IPs, as well as specific API endpoints on ambiguous domains that are used for exfiltrating Twitch OAuth tokens.
Detects network connections originating from browser processes to known JeetBot command and control (C2) infrastructure. The rule identifies suspicious C2 communication and, specifically, attempts at token exfiltration by monitoring for auth tokens in the URL of requests directed to known JeetBot hosts and Twitch-related infrastructure.
