About this tag
Rainbow table attacks are a method used to crack password hashes by precomputing a large set of possible hashes and storing them in a lookup table. On Windows, these attacks often target NTLM authentication, a legacy protocol that remains enabled by default and can expose credentials. Discussions on WindowsForum cover how rainbow table attacks exploit weak or unsalted NTLM hashes, and provide guidance on hardening authentication to mitigate such threats. Topics include disabling NTLM where possible, enforcing stronger protocols like Kerberos, and applying security updates to reduce the risk of credential theft via precomputed hash lookups.

    If you’ve ever wondered whether the relics of IT’s past can come back to haunt you, look no further than NTLM authentication—a sort of ancient curse that’s less Indiana Jones and more Office Space. Windows still ships with this timeworn authentication protocol enabled by default. While it was a...
