This rule monitors for network and email activity associated with known fraudulent AI reseller infrastructure. It aggregates data from device network connections, email URL inspections, and email header analysis to identify potential interactions with malicious domains known to facilitate AI-related fraud.
This rule detects when a DLL containing 'python' in its filename is loaded by a process that is not an identified Python interpreter or the dropbox.exe application. The rule specifically filters for these DLLs being larger than 10MB, which may indicate the use of embedded Python environments to facilitate malicious code execution or side-loading.
This rule monitors various logs (device network events, Entra ID sign-ins, cloud application events, and email events) for any interaction with a predefined list of indicator IP addresses identified as being associated with malicious actor egress traffic.
Detects network connections to known remote tunneling and relay services (e.g., ngrok, Cloudflare Tunnel) initiated by commonly abused LOLBins or processes running from user-writable directories. This behavior is often indicative of an adversary establishing persistent remote access or egress channels for command-and-control communication.
This rule detects potential indicators of compromise related to the 'ATodaPotencia' campaign by monitoring email URL logs, process command-line arguments, and general device events for the string 'ATodaPotencia'. The rule searches across multiple data sources to identify where this specific handle or artifact appears within an environment.
This rule detects activity matching known indicators of compromise (IOCs) associated with recent Russian espionage campaigns, including malicious domains, IP addresses, email senders, file names, and file hashes. It monitors network, sign-in, email, process, and file events across enterprise systems.
Detects outbound network connections from endpoints to domains and IP addresses associated with the Kimsuky (APT43) threat actor group. This rule leverages endpoint network telemetry to identify potential command and control (C2) communication or data exfiltration activities.
KQL Query
This rule detects potentially suspicious file deletion activity originating from PowerShell processes (powershell.exe or pwsh.exe). It monitors for commands targeting temporary directories and specific file extensions (such as .vbs, .lnk, .js, or .ps1) combined with recursive deletion arguments. Additionally, it highlights scenarios where these PowerShell commands are executed by potentially unusual parent processes such as script engines (wscript.exe, cscript.exe, mshta.exe) or other command-line utilities.
This rule detects references to specific social media handles and identifiers associated with the MEK/NCRI (National Council of Resistance of Iran) influence campaign within email URLs, device process command lines, and miscellaneous device events. It is designed to identify potential engagement with or dissemination of influence-related content on endpoints and in email communication.
