Detects the execution of s5cmd.exe with command line arguments indicative of data transfer operations (sync, cp, mv, run) to or from an 's3://' URI. s5cmd is a high-performance command-line tool frequently used for parallel S3 operations, which may be leveraged by adversaries for rapid data exfiltration or staging.
Detects execution of the s5cmd command-line tool performing synchronization, copy, or move operations to a cloud storage URI (s3://) followed by an outbound network connection on port 443 within a 10-minute window. This behavior is indicative of potential data exfiltration to cloud storage.
Detects outbound HTTP requests to the Telegram Bot API associated with the malicious 'indexed-btree' npm package. The rule specifically monitors for hardcoded Telegram bot tokens and chat IDs used for data exfiltration.
Detects outbound network traffic attempting to exfiltrate data to Slack or Telegram APIs using hardcoded bot tokens or channel identifiers associated with the 'indexed-btree' malware campaign.
Detects outbound network traffic attempting to exfiltrate data to Slack or Telegram APIs using hardcoded bot tokens or channel identifiers associated with the 'indexed-btree' malware campaign.
This rule detects a correlation between host-level reconnaissance activity using WMI (via PowerShell or WMIC) to query system information, followed by network exfiltration to a known C2 IP address over a specific URI within a 10-minute window.
Detects high-volume outbound network traffic (exceeding 100MB) generated by processes identifying as 'python-httpx' to non-internal IP addresses. This activity is often associated with automated data exfiltration using Python-based tools.
Detects cloud data access or file download operations in Microsoft 365 (SharePoint, OneDrive, Exchange) performed by a user agent string associated with the python-httpx library. This pattern is often indicative of automated data exfiltration using custom scripts.
Detects high-volume or large-size file access, download, or preview activity originating from known anonymous proxy IP addresses. This behavior is indicative of potential data exfiltration or unauthorized scraping of sensitive documents from cloud storage.
Detects network traffic directed towards Microsoft Graph API that utilizes the 'python-httpx' User-Agent. This combination is often associated with automated scripts, potentially used by adversaries (e.g., Storm-3121/Storm-3032) for automated data collection and exfiltration from Microsoft 365 environments.
Detects high-volume, automated file download or access activity originating from SharePoint Online, OneDrive, or Exchange Online within a 2-hour window. The rule identifies suspicious patterns involving a large number of distinct file events, potentially indicating automated scripts or tools (like python-httpx) performing mass data collection or exfiltration.
Detects high-volume, automated file download or access activity originating from SharePoint Online, OneDrive, or Exchange Online within a 2-hour window. The rule identifies suspicious patterns involving a large number of distinct file events, potentially indicating automated scripts or tools (like python-httpx) performing mass data collection or exfiltration.
Detects anomalous, low-volume data access behavior within cloud applications (such as file downloads, previews, or mail access) that is sustained over an extended period. This pattern often indicates slow, deliberate data exfiltration designed to evade volume-based detection thresholds.
This rule detects file creation or modification events occurring within the 'ProgramData\ZlibDate' directory. This specific path and the associated file extensions (.Dat and .zip) are frequently associated with data staging activities or unauthorized file management by malicious software attempting to persist or exfiltrate data under the guise of legitimate application data.
Detects outbound network traffic (HTTPS and TLS) directed at the specific S3-compatible object storage host 'ams1.vultrobjects.com'. This pattern is associated with 'HEAVYGRAM', a threat actor or toolkit using Vultr S3 buckets for potential data exfiltration.

This rule monitors network traffic for requests directed at a specific domain ('luizestrelhashapr.online') and path ('/google_api/b83fa72d.css'), which is identified in threat intelligence as an indicator of browser history exfiltration.

Detects outbound network communication from common web browsers (chrome.exe, msedge.exe) to a specific malicious domain and path associated with suspected Kremlin-linked screenshot exfiltration activities.
