Intercepting a FIN6 Intrusion, an Actor Recently Tied to Ryuk and LockerGoga Ransomware

Recently, FireEye Managed Defense detected and responded to a FIN6 intrusion at a customer within the engineering industry, which seemed out of character due to FIN6’s historical targeting of payment card data. The intent of the intrusion was initially unclear because the customer did not have or process payment card data.

Our team quickly linked this activity with some recent Mandiant investigations and enabled us to determine that FIN6 has expanded their criminal enterprise to deploy ransomware in an attempt to further monetize their access to compromised entities.
