In the past few weeks, ANSSI became aware of cyber attacks targeting French local authorities. These attacks involved ransomwares whose use resulted in several encrypted files.

This document aims at describing the behaviour of the intrusion set involved in these attacks, as well as providing related indicators of compromise.
