On 12 February 2021, Cyberis identified a weakness in the domain transfer processes of Gandi which allowed any Nominet registry domain (including .co.uk and org.uk domains) registered with Gandi to be transferred out of the owner’s control and into the control of an arbitrary AWS Route 53 account, without any authorisation being provided by the owner of the domain. Exploitation of this weakness did not result in the registrant details being modified in the Nominet registry, but once an adversary has taken control of a domain they are likely to be able to satisfy the checks in place that wo
In 2004, a ragtag fugitive fleet of CISOs created an international group working to define and promote the concept of de-perimeterisation, known as the Jericho Forum. Ten years on, after many valuable contributions to the security industry, it was declared a success and was finally sunsetted in October 2013. In the summer that followed, the UK Cyber Essentials scheme was launched – the Government-backed scheme designed to help organisations protect themselves against common online threats.
Since its inception, the Windows operating system has been a recognizable force within the IT industry and grew increasingly common throughout the 90's and 2000's. Features of the operating system have grown over the last 20 years in response to the changing needs within the industry and shifts in attitudes towards system management, user experience and scale.
Adversary simulation, simulated targeted attack, red teaming… Whatever you want to call it, a technical exercise that assesses your defences by simulating the tactics, techniques and procedures of a real attacker is of great value – especially when you want to understand how well your incident response plans hold out against attack.
Simulating the whole attack chain for most adversaries means that we are not just targeting technology – we are also targeting processes and people.
When working with smaller businesses, sometimes we’re asked whether Endpoint Detection and Response solutions are worth the money, over and above traditional anti-virus. Much of the time, EDR is used in large enterprises in conjunction with a sizeable technical team of experienced professionals who engage in active response and threat hunting as their full-time job. It can be difficult for smaller businesses to see where EDR might fit in.
In a pinch it is possible to hack around this problem by tricking the Nessus scanner into thinking it’s scanning the remote host when it is in fact connecting via a port bound to the localhost. Iptables to the rescue….
Password auditing of a domain traditionally involves obtaining copy of the ntds.dit and performing some offline analysis which can be time consuming. The DSInternals PowerShell Module has an Active Directory password auditing cmdlet which performs checks for default, duplicate, empty and weak passwords. The audit can be performed against a domain online via DCSync, saving the need to obtain a copy of the ntds.dit. This can be of benefit if regular password audits are being performed.
Install DSInternals as an administrator by using:
Vulnerability scanning has an important role in most enterprise threat & vulnerability management programmes – it provides multiple benefits to internal security teams as they identify vulnerabilities and it can also help verify control performance. Associated vulnerability scoring systems, such as the Common Vulnerability Scoring System (CVSS), have also gained widespread industry adoption, as they are simple to understand and usually produce repeatable results.
As a security consultancy, Cyberis undertakes penetration testing for organisations of all sizes, and in many verticals. This testing is often a function of regulatory or compliance requirements, and for some customers' operational teams is viewed as a necessary evil.
Bluetooth technology permeates the modern world. From smart phones to wireless speakers, fitness trackers to WiFi mesh hardware, Bluetooth has become the de facto standard for short-range wireless communications. The chances are that you have Bluetooth enabled devices near you as you read this, and, if you're regularly involved in conference calls, you've probably often used a Bluetooth enabled speaker or VoIP phone.
