SOC Simulator 1/5 - Vecteur initial

Description

During the summer of 2022, an operator of vital importance (OIV) alerts the ANSSI because it believes it is the victim of a major cyber attack. The OIV’s security operation center (SOC) sends an export of its system collection over the last few days. Your job is to understand the attacker’s actions.

Note: The 5 parts are numbered in the chronological order of the attack, but it is not necessary to solve them in order.

Find the name of the vulnerability and the UTC time of the first attempt to exploit it.
