Microsoft has unveiled a groundbreaking AI-powered safety function that addresses one in all cybersecurity’s most persistent vulnerabilities: plain textual content credentials saved in Lively Listing (AD) free-text fields.
The brand new posture alert in Microsoft Defender for Identification leverages synthetic intelligence to detect uncovered credentials with unprecedented precision, serving to organizations determine and remediate identification misconfigurations earlier than they are often exploited.
The difficulty of storing credentials in plain textual content fields inside identification programs like Lively Listing and Microsoft Entra ID has reached alarming proportions.
Key Takeaways1. Microsoft Defender makes use of AI to search out plain-text credentials in Lively Listing.2. 40,000+ uncovered credentials found throughout 2,500 tenants.3. Now in public preview via the Defender portal.
Microsoft’s preliminary analysis revealed greater than 40,000 uncovered credentials throughout 2,500 tenants, highlighting the widespread nature of this safety vulnerability.
These free textual content fields, whereas designed to retailer unstructured knowledge for HR programs, electronic mail signature instruments, or Privileged Entry Administration (PAM) options, typically grow to be repositories for delicate data on account of their versatile, ungoverned nature.
Layered AI Method to Credential Detection
The brand new safety function employs a classy layered intelligence method to credential detection.
The system begins with a complete scan of identification directories, flagging potential credential exposures, together with base64-encoded secrets and techniques and strings matching identified password buildings.
A extra superior AI mannequin then analyzes contextual components such because the related identification kind, worth stability, current adjustments, and references in automation scripts or logs.
Non-human identities (NHI) face disproportionate danger from this vulnerability, as they considerably outnumber human counterparts and can’t make the most of conventional authentication strategies like multi-factor authentication (MFA).
Directors typically retailer service account credentials in description or data fields of AD objects to simplify troubleshooting, creating high-value targets for attackers.

The pace and scale of AI-powered enumeration instruments have diminished exploitation timeframes from hours to seconds, making proactive detection important.
Public Preview Availability
Microsoft Defender for Identification prospects can now entry this new posture advice via public preview.
The function is on the market within the “Publicity Administration” part of the Defender portal, the place organizations can seek for the precise advice to determine potential credential exposures.
This AI-embedded method to posture administration offers safety groups with the identical pace and scale beforehand accessible solely to attackers, enabling proactive menace mitigation earlier than assaults happen.
The know-how represents a major development in identification safety, providing organizations a strong instrument to eradicate the cybersecurity equal of “leaving keys beneath the doormat.”
