🔻 Three critical #EDR threats dropped in the last couple of weeks that fundamentally break how we think about endpoint security.
If your strategy relies on "having #EDR installed and we are secure," know this below tools ready to break in your defence.
below are quick technical summary of the tools and techniques full details technical link in the comment section.
1. #EDRChoker (Silent Choke)
Throttles EDR outbound bandwidth to 8 bits/sec using Windows QoS.
How: Targets pacer.sys below WFP. TLS handshakes time out.
Result: EDR goes blind. Agent looks online. SOC sees nothing.
2. #AI Evasion Malware Lab Factory The attacker had not written a clever new piece of malware. They had built a factory. Wired into the Cursor AI coding IDE and driven by multiple Anthropic Claude Opus 4.5 agents, the setup mass-produced and tested EDR-evasion payloads.
Claude Opus 4.5 mass-produced 70+ evasion techniques against EDRs, #CrowdStrike, #Defender.
Reality is #AI hallucinated success rates, but productivity multiplier is real. One operator now does what took a team of Hackers.
3. #RoguePlanet -NEW RoguePlanet Windows Defender Vulnerability.
Race condition in #Microsoft #Defender → Local Privilege Escalation to SYSTEM.
Impact: Works on fully patched Windows 10/11 (June 2026). Researcher warns: "More Defender vulns coming."
#SOC Actions to catch this tools
#EDRChoker
· Run Get-NetQosPolicy. Monitor Event IDs 4001, 4002.
· Alert on "Sensor Health Status Change."
#AI Factory:
· Hunt \Users\Documents\test\ or \build\out\ executables.
· Alert on >25 LDAP queries in 10 mins.
· Block api.telegram.org & *.workers.dev from workstations.
#RoguePlanet
· Alert on MsMpEng.exe spawning cmd.exe or powershell.exe with #SYSTEM token.
· Disable VHD/VHDX auto-mounting via GPO.
· Prioritize application allowlisting (blocks the exploit entirely).
💼 For Management
1. Tamper Protection: #Sensor dropout must trigger a paged alert.
2. Don't Trust #Defender Alone: More vulns unreleased. Layer controls.
3. Test Your Config: Haven't tested in 30 days? Assume failure.
4. #AI Multiplier is Here: Move from signatures to fundamentals: MFA, patching, allowlisting, segmentation.
Bottom Line is attackers now build factories to bypass your stack, choke telemetry, and weaponize Defender against you. Defend accordingly.
