The latest release from Metasploit, Framework 6.4, is a testament to this ongoing battle. It brings a host of new features and improvements to the forefront of cybersecurity.
It has been a little over a year since Metasploit released version 6.3, and the team at Rapid7 has not been idle.
The new 6.4 version of the Metasploit Framework introduces significant enhancements and new capabilities, building on the solid foundation of its predecessor.
This release underscores Metasploit’s commitment to providing cutting-edge tools for penetration testers and cybersecurity professionals.
Kerberos Improvements
One of the highlights of this release is the substantial improvements made to Kerberos authentication support.
Building on the initial support introduced in version 6.3, Metasploit 6.4 adds new capabilities, including support for the diamond and sapphire techniques alongside the original golden and silver techniques.

Metasploit has recently announced the launch of Metasploit Framework 6.4, according to a recent article by Rapid7.
Furthermore, Metasploit 6.4 introduces a new module that allows users to dump Kerberos tickets from a compromised host, similar to the functionality offered by the popular Rubeus tool.
This enhancement is beneficial for exploiting instances of Unconstrained Delegation, further expanding the toolkit available to cybersecurity professionals.

[*] Auxiliary module execution completedRaj Samani, a Chief Scientist at Rapid7, recently tweeted expressing gratitude towards the Metasploit team and community for their exceptional work in successfully releasing version 6.4 of the Metasploit Framework.
DNS Configuration and New Session Types
Another significant improvement is the enhanced handling of DNS queries within the Metasploit framework.
This update allows users to configure how hostnames should be resolved, which is especially useful in pivoting scenarios.
This ensures that DNS queries for internal resources originate from a compromised host rather than the user’s system, enhancing operational security.
Metasploit 6.4 also introduces new PostgreSQL, MSSQL, MySQL, and SMB session types. These session types allow for interactive queries with remote database instances and direct interaction with SMB shares, including file upload and download capabilities.
This addition streamlines running multiple modules against a single session, improving efficiency and effectiveness.
Examples of manipulating the DNS configuration:
dns add --rule *.lab.lan --session 1 --index 1 192.0.2.1
dns add --rule honeypot.lab.lan --index 2 black-hole
dns add-static example2.lab.lan 192.0.2.201
dns add --index 1 --rule * static system 192.0.2.1Viewing the current configuration:

Metasploit 6.4 supports indirect syscalls, a technique often used by security software to bypass EDR/AV detection and evade dynamic analysis.
This update focuses on substituting Win32 API calls with indirect syscalls to their corresponding native APIs, enhancing the stealthiness of operations conducted with Metasploit.
To aid users in navigating the vast array of modules available within the framework, Metasploit 6.4 introduces improvements to module discoverability.
The new Hierarchical Search feature matches additional fields within modules, making it easier for users to find the tools they need for their tasks.
As an example, this will cause the auxiliary/admin/kerberos/forge_ticket module to show up when the user searches for forge_golden it because it is an action of the module:
msf6 auxiliary(scanner/mysql/mysql_hashdump) > search kerberos forge
