The exposed server at 198[.]245[.]53[.]26 gave a rare opportunity to compare two related Banana RAT branches through live infrastructure, sandbox telemetry, and recovered payloads. The older branch used ETW-themed paths, static Microsoft-looking names, and a typo-based pseudo-Microsoft C2 identity. The newer branch kept the same staging concept but moved to randomized install identifiers, better-structured SYSTEM persistence, and a WebSocket channel built around a hashed testewin.com subdomain.
