The threat actors stayed dormant for most of this time, before jumping into action on an early Saturday morning. The ransomware itself uses a relatively common anti-analysis technique sometimes referred to as “API-by-hash,” in which Conti uses hash values to call specific API functions; Conti has an added layer of encryption over the top of these hashes to futher complicate the work of a reverse engineer. Once deployed, Conti performs sandbox evasion via system checks to determine if it is running on a virtual machine environment or sandbox. 2017 Microsoft Windows Server Message Block 1.0 server vulnerabilities; [, "PrintNightmare" vulnerability (CVE-2021-34527) in Windows Print spooler [, "Zerologon" vulnerability (CVE-2020-1472) in Microsoft Active Directory Domain Controller systems.[.
