VERY IMPORTANT

We first noticed that there may be a relationship between the Vatet loader, PyXie Remote Access Tool (RAT) and Defray777 ransomware when there were remnants and/or detections of all three in various Incident Response and Managed Threat Hunting engagements. After digging deep into each malware family, it became apparent that Vatet, PyXie and Defray777 are all associated with the same financially motivated threat group that has been operating since as early as 2018. That threat group, sometimes referred to as PyXie by BlackBerry Cylance and GOLD DUPONT by SecureWorks, has been actively conducting successful ransomware operations that have impacted organizations in a number of sectors including healthcare, education, government and technology while remaining under the radar.
