Sysmon Event ID 10 LSASS process access.Event ID 4624 with Logon Type = 9, Authentication Package = Negotiate, and Logon Process = seclogo.The best way to spot overpass-the-hash hacking attacks is to use the same strategy as for detecting pass-the-hash: Look for the following event log signature in each endpoint’s authentication process: If we use the klist command, we should see AES256-encrypted Kerberos tickets being used for our authentication:ĭetecting Overpass-the-Hash Attacks Using pass-the-hash detection techniques This will be more difficult to detect as it will use more secure and commonly used encryption keys.

Once we have access to the user’s AES keys, we can abuse them without actual privilege escalation.įrom there we can issue a pass-the-hash command to inject the AES key into a Kerberos ticket. Or you can use the sekurlsa::ekeys command on your local system. The DCSync command returns this information for any user in the domain if you have the proper Active Directory permissions. Mimikatz enables you to extract AES keys in a couple different ways. You can also create Kerberos tickets using other information about a user, such as their AES keys. Other options for performing overpass-the-hash attacks For more details, read Benjamin Delpy’s blog post. This is supported primarily for backwards compatibility, but it can also be exploited - all you need is a user’s NTLM hash to create a Kerberos ticket with the lowest level of security. This is possible because Microsoft provides the ability to create RC4-HMAC-MD5-encrypted Kerberos tokens based on NTLM hashes. Not only did we just pass the hash, we overpassed it: The NTLM hash was passed into the Kerberos authentication provider using RC4 encryption. Using the NTLM hash, we can perform a overpass-the-hash attack: Sekurlsa::pth /user: /domain: /ntlm: For that we will use Mimikatz: Privilege::debug

The first step is the same as for a pass-the-hash attack: Obtain the NTLM password hash (NT hash) for a user account we want to compromise. Obtain the password hash of a user account.

Please note, you must provide your email address in order to receive an email with the download link.Active Directory Security Best Practices Once your hash is displayed in the dialog, you can copy it to the clipboard by right-clicking the value and selecting Copy (you get a magnet URL option here, too).Īnd there's even a 'Compare a file' option which allows you to hash other files for an immediate comparison. Check the boxes next to your preferred options and they'll be available next time.

Not what you need? Click Settings for a full list of the functions on offer: Adler32, CRC32, MD2, MD4, MD5, RIPEMD(128,256,320), SHA-1,256,384,512, Tiger, and Whirlpool. Once the program is installed, for instance, just right-click something, select Properties > File Hashes, and you'll see the CRS32, MD5 and SHA-1 hashes for that file. HashTab makes all this considerably simpler, though, by just displaying your required hashes right in the file Properties dialog.

You'll typically have to launch that particular program, import the files, choose the options you need, manually copy the hash value, and so on. There are plenty of tools around which will calculate file hashes for you (values which represent the digital fingerprint of a file), but most aren't so convenient to use.
