MITRE ATT&CK

Techniques & procedures

7 distinct techniques documented for this family, organized by ATT&CK tactic.

Persistence

1 technique

T1112Modify RegistryEvidence1

The rules take effect immediately and persist after the target reboots Windows.

Stealth

2 techniques

T1070Indicator RemovalEvidence1

EDRChoker.exe To remove all installed QoS Policy

T1070.004File DeletionEvidence1

The tool, available on GitHub, operates in two modes: Remove mode — Executed with no parameters to cleanly purge all installed QoS policies.

Defense Impairment

1 technique

T1112Modify RegistryEvidence1

The rules take effect immediately and persist after the target reboots Windows.

Impact

2 techniques

T1490Inhibit System RecoveryEvidence1

Policy-based QoS (Quality of Service) allows you to set an absolute outbound bandwidth limit (throttling rate) for specific applications, ports, or protocols in Windows... EDRChoker... creates QoS policies that limit those processes to 8 bits per second.

T1498Network Denial of ServiceEvidence3

Modern EDR platforms rely on a persistent, low-latency connection between the endpoint agent and a cloud-based management server. Sever that connection and the EDR agent effectively goes dark, unable to report detections, receive updated policies, or accept remote commands from administrators.

2 techniques

T1562Impair DefensesEvidence4

EDRChoker uses Policy-based Quality of Service (QoS) to set hard bandwidth caps (throttling) on Endpoint Detection and Response (EDR) agents, causing them to always time out - effectively blocking them.

T1562.001Disable or Modify ToolsEvidence1

Developed by security researcher @TwoSevenOneT, the tool exploits Windows Policy-Based Quality of Service (QoS) to throttle EDR processes to near-zero bandwidth, effectively isolating them from their command infrastructure.

EDRChoker: Choking The Telemetry Stream to Bypass Defenses : r/netsec

A tool or malware referred to as EDRChoker that interferes with EDR telemetry by throttling agent bandwidth via Policy-based QoS, causing agent communications to time out and effectively blocking defenses.
