Detects the execution of command-line archiving utilities (e.g., 7z, rar, zip) to create potentially password-protected archives within common staging directories (Temp, Public, ProgramData), followed by an outbound network connection to an external destination. This behavior is consistent with data staging and subsequent exfiltration.
Detects the creation of password-protected archives using 7-Zip or WinRAR command-line utilities. Adversaries often use these tools to compress and encrypt data prior to exfiltration to bypass security controls and prevent inspection of contents.
Detects unauthorized data staging activities using archival utilities followed by data exfiltration to known public cloud storage providers. The rule specifically excludes hosts experiencing mass file renaming activity, focusing on extortion-only scenarios where data is stolen without encryption.
This rule detects potential browser-based credential and session theft by monitoring for a process that accesses multiple sensitive web browser artifacts (cookies, local state, session storage) across several user profiles in a short timeframe. It correlates this activity with the subsequent creation of a compressed archive in a temporary directory followed by an outbound network connection, indicating a multi-stage exfiltration workflow.

It correlates this activity with the subsequent creation of a compressed archive in a temporary directory followed by an outbound network connection, indicating a multi-stage exfiltration workflow.
Detects a sequence of potentially malicious activity involving the bulk reading or downloading of sensitive AI-related artifacts (model files, datasets), followed by the staging of these files into a compressed archive, and finally an outbound network transfer to an external IP address. This behavior pattern is indicative of data exfiltration of intellectual property.
Detects the execution of WinRAR utilities (WinRAR.exe, Rar.exe) with suspicious command-line arguments typically associated with data staging, archiving, or encryption. The rule filters out legitimate WinRAR installations and only triggers when the process is spawned by a script interpreter (e.g., PowerShell, CMD) or operates within sensitive file paths (e.g., Users, Shares, Finance, HR, Backup).
Detects the installation of known AI-powered coding assistant extensions (e.g., Copilot, Tabnine, Cursor) on a device, followed by significant source-code repository cloning or archival activity by Git within two hours. This pattern is potentially indicative of intellectual property theft or sensitive source code exfiltration facilitated by a newly introduced AI tool.

This pattern is potentially indicative of intellectual property theft or sensitive source code exfiltration facilitated by a newly introduced AI tool.
Detects the use of 7-zip (7z.exe) to interact with a specific file (drata.dat) using command-line arguments typical of an archival or extraction operation. This may indicate an adversary attempting to stage, compress, or exfiltrate sensitive data.
Detects anomalous, high-volume file access by a single process, followed by local file compression or archiving, and subsequent outbound data transfer to a non-internal IP address. This pattern is characteristic of automated agents (like those used in the GTG-1002/Anthropic AI-orchestrated campaigns) performing rapid data triage and staging for exfiltration.

Detects a single host or account interacting with a high volume of archive (PST/OST) and document files, or initiating mailbox exports within a short window, which is often indicative of mass data staging and collection prior to exfiltration.
Detects the use of PowerShell to execute the 'Compress-Archive' cmdlet against a file named 'download.bin'. This behavior is commonly used by adversaries to compress staged data, potentially for exfiltration, or to manipulate artifacts downloaded from an external source.

Detects the use of database or archiving command-line utilities to export data related to RADIUS services. The rule filters out known backup service accounts and authorized backup processes, flagging activity that occurs outside of standard business hours or is performed by accounts not explicitly designated for administrative or database maintenance tasks.

Detects the creation of compressed archive files (zip, rar, 7z, dat) followed by a significant network upload (exceeding 5MB) on the same host within a 30-minute window, which is indicative of staging and exfiltrating collected data.
Detects the use of database or archiving command-line utilities to export data related to RADIUS services. The rule filters out known backup service accounts and authorized backup processes, flagging activity that occurs outside of standard business hours or is performed by accounts not explicitly designated for administrative or database maintenance tasks.
