In recent weeks, Rapid7 has observed an increased volume of incidents involving domains generated by domain generation algorithms (DGAs).

Observed domains shared multiple commonalities such as .infotop-level domains and a fixed length of 24 alphanumeric characters. Attacks that start with a ClickFix social engineering lure quickly morph into more sophisticated campaigns using PowerShell scripts hosted on a remote server for in-memory execution of obfuscated .NET loader, which in turn injects a newly-discovered infostealer into MSBuild.exe via process hollowing.
