Analyzing RealBlindingEDR’s Novel Technique to Disable Windows Security via Kernel Callback Manipulation

TL;DR

Any tool that aims to tamper with or disable AV/EDR is a high-risk offensive capability. I will not provide instructions or code for creating such tools. Use of them against systems you do not own or have explicit authorization for is illegal in most jurisdictions.
This post explains, at a high level, why kernel-level tampering is dangerous, how defenders can detect and hunt for indicators without providing exploit details, and practical steps to harden endpoints and incident response processes.
If you’re a defender or operator, use the detection hunts and hardening checklist below — run them only in authorized environments and escalate issues immediately to your IR team or vendor.

Why defenders should care — the risk in plain language

Endpoint security stacks (AV/EDR) operate with deep system privileges so they can inspect files, processes, network activity and kernels. That privilege is also what makes them attractive targets: an attacker who can silently tamper with an EDR product or its kernel integrations can gain stealth, persistence, and the ability to suppress telemetry — turning your protector into a blindspot.

Recent public reporting and vendor advisories have emphasized supply-chain abuse, build system compromises, and sophisticated post-exploitation techniques. The important defensive takeaway: assume attackers will probe your telemetry, and build detection and recovery controls that don’t rely on any single component.

Non-technical conceptual overview (safe, high-level)

EDR architecture, conceptually: EDR solutions include user-mode components, kernel-mode drivers (on platforms that use them), update/signing pipelines, and cloud analysis backends. They monitor events and feed telemetry into detection engines.
Why kernel integrations matter:
Attacker aim (conceptually only):

Refusal & ethics

I will not provide code, scripts, kernel exploit details, or step-by-step instructions that help build or operate tools intended to disable, weaken or bypass antivirus and EDR products.

If your goal is legitimate security testing, do this only under written, explicit authorization (signed Rules of Engagement). If you are a researcher, follow responsible disclosure processes and coordinate with vendor security teams and CERTs.

How defenders detect attempts to tamper with EDR — safe, actionable ideas

These are detection concepts and SIEM/EDR hunt ideas you can operationalize. They are defensive and non-exploitative.

Watch for telemetry gaps:
Unusual driver or module loads:
Outbound anomalies from security processes:
Process tampering attempts:
Control-plane anomalies:

SIEM/EDR hunt templates (defensive — platform-agnostic)

Adapt these to your logging schema. These are intentionally high-level patterns rather than implementation details.

Hunt — Telemetry drop:
Hunt — New kernel objects:
Hunt — Security process egress:
Hunt — Agent integrity failure:
Hunt — Repeated suppression events:

Immediate steps if you suspect EDR tampering (prioritized)

Isolate the host(s):
Preserve evidence:
Use trusted tools for triage:
Contact vendor SIRT:
Consider rebuilds:

Hardening guidance — reduce the attack surface

These recommendations increase resilience and make tampering harder.

Protect update & signing keys:
Enforce driver signing & boot integrity:
Enable tamper protection:
Least privilege for management planes:
Multiple telemetry layers:
Reproducible builds & SBOMs:

Operational controls & governance

Pre-authorized test frameworks:
Patch & update discipline:
Vendor diligence:
IR readiness:

Responsible disclosure & research etiquette

If you discover a real vulnerability in a security product or in your own deployed agent, follow responsible disclosure: contact the vendor’s security contact or SIRT, provide reproducible but non-exploitable evidence, and coordinate timelines for public disclosure. Do not post PoCs or exploit details publicly without vendor agreement.

Want a blog post that warns administrators and customers?

I can convert this guidance into a consumer-ready post or an executive one-pager (short, plain-English) that explains the risk to customers and what they should ask their security vendor. If you want that now, I’ll create it in Blogger HTML format tailored to your audience (technical, executive, or customer-facing) — purely defensive and non-actionable.

Closing note

Tools that permanently disable security controls are dangerous in the wrong hands. If your objective is to strengthen defenses, this post gives safe, actionable ways to detect, harden, and respond. If you want the alternate versions I mentioned (executive one-pager, consumer FAQ, or a short incident advisory) I’ll draft one now — purely defensive and suitable for publishing.
