Preface:
Integrated Windows Authentication utilizes Negotiate/Kerberos or NTLM to authenticate users based on an encrypted ticket/message passed between a browser and a server. This is the standard authentication algorithm for Microsoft products.

Design weakness:
Hacker steal the NTLM Credentials via PDF Files. They exploit NTLM hash leaks stealing a Windows user’s NTLM hashes.
