Domain Hijacking Via Logic Error - Gandi and Route 53 Vulnerability

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

Cyber Essentials De-Perimeterised

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.

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.
