hideandsec.sh
hideandsec.sh is a (French) security research blog known for deep AD / PKI
attack research — most notably the Shadow Credentials work
(msDS-KeyCredentialLink key-trust abuse) that this wiki’s
shadow-credentials and pkinit-unpac-the-hash pages are built on, plus
PKINIT and Kerberos pre-auth research.
Key contributions referenced in this wiki
- Shadow Credentials — the
msDS-KeyCredentialLinkplant → PKINIT → NT hash recovery technique (shadow-credentials, whisker). - PKINIT / UnPAC the hash — certificate-based Kerberos pre-auth and
PAC_CREDENTIAL_INFONT-hash recovery (pkinit-unpac-the-hash, kerberos-pac). - Kerberos / PKI research feeding kerberos-preauth and kerberos-authentication.
Why it matters for this wiki
- It is the technique source for the shadow-credential / PKINIT attack family — the “plant a cert, become the account, read their hash” play.
