Nowadays, security efforts primarily focus on web applications, internal infrastructures, Active Directory, and other traditional attack surfaces. Yet with the rise of remote work, employees’ workstations are increasingly exposed to theft. In this context, the main security measure available to…
The rise of generative AI and Large Language Models (LLMs) like ChatGPT has disrupted digital practices. More companies choose to deploy applications integrating these language models, but this integration comes with new vulnerabilities, identified by OWASP in its Top 10…
Audits and Red Team assessments led by Wavestone showed a stark imbalance between the maturity of on-premise infrastructure protection and the cloud deployment ones. While on-premise infrastructure are generally well identified, controlled and protected according to proven standards, their cloud…
It's time to begin the second part of our Zimbra investigation. If you haven't read the first part yet, we strongly recommend starting HERE before continuing.In this second part, we'll assume that an attacker has managed to compromise a Zimbra…
