This generally means loading the hashes in a cracking program, which will generate password hashes for the corresponding type using plain-text inputs that we define. Cracking Password Hashesįor most password hash types, cracking will thus be needed to identify the plaintext password corresponding to the obtained hash. An /etc/shadow hash will not be immediately reusable.

A Kerberos ticket giving you access to a service will not allow you to impersonate that service account. Once you obtain this hash, it could be reusable in a Pass-The-Hash attack (e.g., NThashes), īut oftentimes it will not be. Maybe you requested a Kerberos ticket for an account that has a Service Principle Name (SPN) set, Īnd now want to get the plaintext password from the NThash.

Or perhaps you dumped them from LSASS memory on a Windows system. Password Hashes: Which Types, and How They Are Obtainedĭuring a Red Team engagement or a penetration test, you might stumble on password hashes lying around in a file on a shared folder (e.g., in config files or /etc/shadow).

Understanding why hash cracking is resource-intensive.

Understanding the basic principle of password hashing, including the why and how.Let’s start by ensuring that you have some important prerequisites in place: As password cracking stations can be expensive to purchase, tend to age quickly, and run idle for long periods of time, the shared nature of cloud environments makes the cloud a great alternative to an on-premise cracking station. This article will discuss the use of cracking cloud computing resources to crack password hashes. In other words, secret phrases have been in use for a long time in security. But consider that the Romans also used “watchwords” for military purposes. For us, what might come to mind is a login password for a computer or an encryption password to keep data confidential. Passwords to secure access to resources have been around for longer than you might think.
