Bypass Record
Tamper-Protection Bypass × Zscaler Client Connector for Windows
A publicly-reported instance of Tamper-Protection Bypass bypassing Zscaler Client Connector for Windows, recorded with its original source. Factual record; no assessment of any specific deployment.
Mechanism
Improper verification of cryptographic signatures in the anti-tampering mechanism allows an attacker to disable the protection without a valid signature. The network-based attack vector requires no authentication or user interaction, enabling remote exploitation to neutralize endpoint agent defenses.
Detection & mitigation
Monitor for unexpected termination or suspension of Zscaler Client Connector processes and services, especially when not initiated by authorized administrative actions. Ensure all endpoints are updated to Zscaler Client Connector version 4.2.0.190 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.
