bind link
About this tag
The bind link tag on WindowsForum.com covers discussions about a Windows 11 feature that allows filesystem redirection via the Bind Link API and bindflt.sys driver. Recent threads focus on proof-of-concept tools like EDRStartupHinder and EDR-Redir V2 that abuse bind links to evade security products, including Windows Defender. These tools create bind links to redirect critical system or EDR folders to attacker-controlled locations, enabling DLL hijacking and preventing security agents from initializing. The content highlights how bind links can be exploited for local privilege escalation and defense evasion, making this a key topic for security researchers and IT administrators concerned with Windows 11 hardening and detection of advanced threats.
A newly published proof‑of‑concept (PoC) called EDRStartupHinder demonstrates a local, pre‑boot startup technique that can prevent antivirus and EDR agents from initializing on Windows 11 25H2 by abusing the platform’s Bindlink API and the interaction between DLL loading and Protected Process...
A public proof‑of‑concept called EDR‑Redir V2 can redirect Windows EDR product folders to attacker‑controlled locations by abusing Windows’ new bind link and cloud filter APIs, allowing DLL hijacking and other local evasion techniques — a demonstration that reportedly blinded Windows Defender on...
EDR-Redir V2 is the latest proof‑of‑concept tool to exploit Windows’ new bind link facility and the cloud filter stack to create parent‑level filesystem redirections that can blind Endpoint Detection and Response (EDR) products — including a demonstrated bypass of Windows Defender on Windows 11...
