This presentation will cover our research on the NetWalker ransomware from the beginning of March 2020 to today. We will speak about the technical changes we have observed since March (from the start of the COVID-19 pandemic, the use of initial spear-phishing access and VBS code to the use of a CVE exploit and RDP compromised account as initial access; the PowerShell payload; and what's going on when the attackers are inside the internal network). We will also discuss the eriknetwalker story that we attempted to link to the current NetWalker ransomware with similarity code, etc.; and also how we follow the money by tracking BTC transactions. We will also present our hypotheses about the actor (team) behind NetWalker.
