Bypass Record
Tamper-Protection Bypass × Palo Alto Networks Cortex XDR Agent
A publicly-reported instance of Tamper-Protection Bypass bypassing Palo Alto Networks Cortex XDR Agent, recorded with its original source. Factual record; no assessment of any specific deployment.
Mechanism
The Cortex XDR agent fails to properly verify cryptographic signatures on files, allowing an attacker to run untrusted executables that should be blocked by the agent's executable blocking feature. This bypasses the detection/blocking mechanism.
Detection & mitigation
Monitor Cortex XDR agent logs for unexpected process creation events that should have been blocked by policy, and correlate with signature verification failures. Ensure agents are updated to versions 7.9.102-CE, 8.1.3, 8.2.2 or later to remediate the vulnerability.
This is a record of a publicly-reported event, not an assessment of any specific organization's deployment. Detection and mitigation notes are drawn from the cited source. Where the source is silent, fields are omitted.
