Bitdefender researchers showed that a legitimate Windows feature called bind links can be abused to make malware appear harmless or invisible to some endpoint security tools on Microsoft systems. The techniques use bindflt.sys path redirection to create conflicting filesystem views, including 'file-binding' to swap trusted DLL loads such as amsi.dll and 'process-binding' to make security tools inspect an innocent file path while a different attacker-controlled file runs; Microsoft reportedly rated the issue low severity because it requires administrator access.
Why it matters: Organizations using Windows should treat bind-link abuse as a practical post-compromise stealth technique, especially where attackers may already have admin rights. Defenders should review EDR visibility around bind links, hunt for unusual bindflt.sys activity and trusted-path DLL or executable redirection, and harden privilege controls.

This article establishes a distinct new story about a newly publicized Windows EDR-evasion technique based on bind links, not a follow-up to an existing tracked breach, CVE, or patch event.
