Quick Answer: What Is A Pass The Hash Attack?

What is Hashdump?

The “hashdump” command is an in-memory version of the pwdump tool, but instead of loading a DLL into LSASS.exe, it allocates memory inside the process, injects raw assembly code, executes its via CreateRemoteThread, and then reads the captured hashes back out of memory..

What is Silver Ticket attack?

A Silver Ticket is a forged service authentication ticket. A hacker can create a Silver Ticket by cracking a computer account password and using that to create a fake authentication ticket. … In the simplest terms, a Silver Ticket is a forged authentication ticket that allows you to log into some accounts.

Why does pass the hash work?

In cryptanalysis and computer security, pass the hash is a hacking technique that allows an attacker to authenticate to a remote server or service by using the underlying NTLM or LanMan hash of a user’s password, instead of requiring the associated plaintext password as is normally the case.

What are pass the hash and pass the ticket attacks?

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 is a golden ticket attack?

The Golden Ticket Attack, discovered by security researcher Benjamin Delpy, gives an attacker total and complete access to your entire domain. It’s a Golden Ticket (just like in Willy Wonka) to ALL of your computers, files, folders, and most importantly Domain Controllers (DC).

What is Kerberos attack?

During such attacks, threat actors target domain administrator privileges, which provide unrestricted access and control of the IT landscape. Armed with these privileges, attackers can stealthily manipulate Domain Controllers (and Active Directory) and generate Kerberos tickets to obtain unauthorized access.

How does Golden Ticket attack work?

A Golden Ticket attack is a type of attack in which an adversary gains control over an Active Directory Key Distribution Service Account (KRBTGT), and uses that account to forge valid Kerberos Ticket Granting Tickets (TGTs).

What is the difference between LM and NTLM passwords hashes?

The LM hash has a limited character set of only 142 characters, while the NT hash supports almost the entire Unicode character set of 65,536 characters. 3. The NT hash calculates the hash based on the entire password the user entered. The LM hash splits the password into two 7-character chunks, padding as necessary.

What is pass the hash vulnerability?

A pass the hash attack is an expoit in which an attacker steals a hashed user credential and, without cracking it, reuses it to trick an authentication system into creating a new authenticated session on the same network. … Organizations should closely monitor hosts and traffic within their networks for suspect activity.

What is a pass the ticket attack?

Pass-the-Ticket attacks are a category of post-exploitation attacks involving the theft and re-use of a Kerberos ticket to authenticate to systems in a compromised environment. … Once an attacker is on a system, they will attempt to elevate privileges to get access to tickets stored in other Active Directory sessions.

How does NTLM hash work?

The NTLM protocol uses one or both of two hashed password values, both of which are also stored on the server (or domain controller), and which through a lack of salting are password equivalent, meaning that if you grab the hash value from the server, you can authenticate without knowing the actual password.

What is the difference between Kerberos and LDAP?

LDAP and Kerberos together make for a great combination. Kerberos is used to manage credentials securely (authentication) while LDAP is used for holding authoritative information about the accounts, such as what they’re allowed to access (authorization), the user’s full name and uid.
