In dimineata zilei de luni, la ora 07:45, administratorul de sistem primeste alarme multiple din sistemul de monitorizare (Zabbix) si sesizari de la angajati ca nu pot accesa fisierele de pe serverul de fisiere.

Simptomele identificate

• Fisierele de pe serverul principal sunt criptate si au extensia .locked adaugata
• Apare un fisier README_DECRYPT.txt pe desktop-urile mai multor utilizatori
