Practical DMA attack on Windows 10

Among the various security assessments performed by Synacktiv, some involve attacking the security hardening of a laptop or workstation master image that will be massively deployed in an infrastructure. The purpose of this kind of security assessment is to give the client an overview of its level of maturity regarding security concerns and provide him with some recommendations in order to increase his level of security.

This post describes how Synacktiv defeated a workstation security measures by using a hardware approach.

Breaking namespace isolation with PF_RING before 7.0.0

Linux hardening and proper isolation using containerization can be tricky especially when performance is critical.

This post is a feedback on the unlikely integration of fast sniffers with linux containers.

netdata apps.plugin security fixes

Synacktiv met netdata in the wild in the last few months. This blog post aims at telling the story of a vulnerability which was first forgotten 1 year ago and then partially fixed. On a standard setup, the vulnerability can be exploited by gid netdata to read arbitrary files owned by root. On a weak setup (as seen in the wild by Synacktiv), the vulnerability can be exploited by all users.
