Does pass the hash work on Linux?

Not to be too hard on Windows, PtH is also an issue in Linux systems that implement Kerboros , where you have an equivalent pass-the-ticket or PtT attack. Here’s the most important takeaway: you can’t prevent PtH, you can only mitigate or greatly reduce the possibility of this attack occurring.

Which Metasploit module can be used to dump password hashes of a compromised Windows endpoint?

The psexec module is often used by penetration testers to obtain access to a given system that you already know the credentials for. It was written by Sysinternals and has been integrated within the framework.

What is exploit Windows SMB PsExec?

PsExec is one of the most popular exploits against Microsoft Windows. It is a great way to test password security and demonstrate how a stolen password could lead to a complete compromise of an entire corporate network. To be able to use exploit/windows/smb/psexec : A valid username and password must be set.

What is PsExec module?

The PSExec Command Execution Module (auxiliary/admin/smb/psexec_command. Instead it issues a single Windows command to the system. This command is then run by the remote system. This allows arbitrary commands to be executed on the remote system without sending any payloads that could be detected by AV.

How does pass-the-hash works?

A Pass-the-Hash (PtH) attack is a technique whereby an attacker captures a password hash (as opposed to the password characters) and then simply passes it through for authentication and potentially lateral access to other networked systems.

What’s the difference between pass-the-hash and pass the ticket?

One primary difference between pass-the-hash and pass-the-ticket, is that Kerberos TGT tickets expire (10 hours by default) whereas NTLM hashes only change when the user changes their password. So a TGT ticket must be used within its lifetime, or it can be renewed for a longer period of time (7 days).

How does pass-the-hash work?

Does PsExec use SMB?

PsExec allows for remote command execution (and receipt of resulting output) over a named pipe with the Server Message Block (SMB) protocol, which runs on TCP port 445. Utilizes the Service Control Manager (SCM) to start the PsExecsvcservice and enable a named pipe on the remote system.

How to change nopassword in PSExec pass the hash?

One important thing to note on this is that if NTLM is only available (for example its a 15+ character password or through GPO they specify NTLM response only), simply replace the ****NOPASSWORD**** with 32 0’s for example: While testing this in your lab, you may encounter the following error even though you are using the correct credentials:

What’s the best way to pass the hash?

Often as penetration testers, we successfully gain access to a system through some exploit, use meterpreter to grab the passwords or other methods like fgdump, pwdump, or cachedump and then use rainbowtables to crack those hash values. We also have other options like pass the hash through tools like iam.exe.

How are hashes extracted from a compromised machine?

Extraction of hashes – This can be done from a machine that the attacker directly attacked or from the machine that was in the same network as the compromised machine. Using the hashes to gain access to the compromised machine or another machine.
