CAPEC-649: Adding a Space to a File Extension
Description
Extended Description
When authenticating via LM or NTLM, an authenticating account's plaintext credentials are not required by the protocols for successful authentication. Instead, the hashed credentials are used to determine if an authentication attempt is valid. If an adversary can obtain an account's hashed credentials, the hash values can then be passed to a system or service to authenticate, without needing to brute-force the hashes to obtain their cleartext values. Successful Pass The Hash attacks result in the adversary fully authenticating as the targeted account, which can further allow the adversary to laterally move within the network, impersonate a legitimate user, and/or download/install malware to systems within the domain. This technique can be performed against any operating system that leverages the LM or NTLM protocols even if the operating system is not Windows-based, since these systems/accounts may still authenticate to a Windows domain.
