dump sales order

Hunt Hypothesis

The “dump sales order” rule detects potential exfiltration of sensitive sales data through suspicious file dumping behavior, which may indicate an adversary attempting to extract valuable information from the environment. SOC teams should proactively hunt for this behavior in Azure Sentinel to identify and mitigate early-stage data exfiltration attempts that could lead to larger breaches.

YARA Rule

rule dump_sales_order {
    strings: $ = "../../../../../../app/Mage.php'; Mage::app(); var_dump(Mage::getModel('sales/order')"
    condition: any of them
}

This YARA rule can be deployed in the following contexts:

• Microsoft Defender for Endpoint — Custom indicators / advanced hunting
• Email Gateway — Attachment scanning
• File Share Monitoring — Periodic scanning of shared drives
• YARA CLI — Manual threat hunting on endpoints
• Source Rule
