A Domain Controller has two type of user accounts: Domain Admins and Domain Users. Domain Users: Domain Users are the users who have rights to login into the Domain Controller but have no privileged access to make changes on the Domain Controller. Domain Admins: Domain Administrators or Domain Admins are high privileged users of a Windows domain and have the power to make changes to the Domain Controller. They are like local administrators of the Domain Controllers. As already explained in another section of this same Issue, both of these user's password hashes are stored in NTDS.dit file which is present on the Domain Controller. Both of these users can login into the Domain from a Client system which is part of the Windows Domain. If we can dump the…

Welcome to Metasploit This Month. Let us learn about the latest exploit modules of Metasploit and how they fare in our tests. Hashicorp Nomad RCE Module TARGET: Nomad TYPE: Remote ANTI-MALWARE: OFF MODULE: Exploit Nomad is a flexible workload orchestrator that enables an organization to easily deploy and manage any containerized or legacy applications using a single, unified workflow. Using Nomad Client, users can create jobs that can run in a Nomad cluster. Nomad provides a variety of drivers to allow for tasks to be run under. The 'raw_exec' and 'exec' drivers allow for OS commands to be run on a Nomad client. The 'raw_exec' option runs with higher privileges, while 'exec' is typically limited to lower privileges. The API operates similarly to HashiCorp's Consul service, by allowing optional ACL…

Syed Wajid Ali Shah Research Fellow, Centre For Cybersecurity Research and Innovation, Deakin University Jongkil Jay Jeong CyberCRC Research Fellow, Centre For Cybersecurity Research and Innovation, Deakin University Robin Doss Research Director, Centre For Cybersecurity Research and Innovation, Deakin University It’s now well known that usernames and passwords aren’t enough to securely access online services. A recent study highlighted more than 80% of all hacking-related breaches happen due to compromised and weak credentials, with three billion username/password combinations stolen in 2016 alone. As such, the implementation of two-factor authentication (2FA) has become a necessity. Generally, 2FA aims to provide an additional layer of security to the relatively vulnerable username/password system. It works too. Figures suggest users who enabled 2FA ended up blocking about 99.9% of automated attacks. But as with…

A new version of Kali Linux, the Kali Linux 2021.3 has been released on 14 September 2021. Let's see what's new in this release. OpenSSL Starting from this version, the OpenSSL in Kali Linux will be configured to be compatible with old protocols of SSL. This means that legacy protocols like TLS 1.0 and TLS 1.1 and further older ciphers are enabled by default. This has been done to help increase Kali’s ability to talk to older, obsolete systems and servers which may be still using these older protocols thus increasng potential attack surface. New Tools Just like any new release of kali, they have added more tools in this release too. The new tools added to kali repository in this release include, Berate_ap - A Tool to orchestrate MANA…
