SOC Simulator 4/5 - Latéralisation

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.

Over a short period of time, the attacker tried to connect to numerous machines, as if trying to reuse the secrets stolen in part 2. This enabled him to connect to the Workstation2 machine. Find the source IP, the account used and the UTC time of this connection.

Flag format (case insensitive): FCSC{192.168.42.27|MYCORP\Technician|2021-11-27T17:38:54}
