Logon Type 9 is very rare. However, I was able to generate some false positives running applications that use impersonation. The main difference to key off of is the Logon Process will always be “seclogo” for pass the hash (from my tests), so you can filter on that to reduce false...
Using this method it is possible to accurately detect PTH attacks originating from all publicly known non-standard implementations of NTLM existing in tools such as Impacket, Metasploit, and Invoke-TheHash.Phillip Tsukerman
The NTLMv1 hashing algorithm takes as input the NT hash of a password and a challenge provided by the server. It concatenates the NT hash with five bytes of zeros. It splits this string into three 7-byte keys. Those keys are used to encrypt the challenge using DES. The cryptograms ar...
PtH Detection & Mitigation: SimplifiedWhat is a pass-the-hash cyberattack? Pass-the-hash is an attack technique attackers use to obtain the NTLM or LANMAN hash of a user's password instead of the plain text password so they can use it to dupe an authentication system. This strategy, highl...
How to mitigate a pass the hash attack To mitigate the threat of a pass the hash attack, organizations should ensure domain controllers can only be accessed from trusted systems without internet access.Two-factor authenticationthat usestokensshould also be enforced, as well as theprinciple of least...
An attacker uses a Pass-the-Hash attack to steal a “hashed” user credential without having to crack it to get the original password.
Pass the hash is a type of cybersecurity attack in which an adversary steals a “hashed” user credential and uses it to create a new user session on the same network.
Step 1. Extract the TGT. To perform a pass-the-ticket attack with Rubeus, the first step is to obtain a TGT. TGTs and NTLM hashes may or may not be stored on a system after a user logs off, based on security settings. One of the fun/scary features of Rubeus is Monitor, which ...
The way Remote Credential Guard (RCG) operates can indeed trigger a Pass-the-Hash (PtH) attack alert in Microsoft Defender for Identity (previously known as Azure Advanced Threat Protection or Azure ATP). RCG uses a similar approach to a PtH attack to aut...
When you can determine the next steps attackers will likely take, you can be much more effective in detection and better positioned to appropriately respond. How to defend against a pass-the-hash attack There are several methods you can use to defend a network against a PtH attack, although ...
