The evm-tx-decoder RubyGem version 0.9.1 contains malicious code embedded in its native-extension build script extconf.rb. This script decodes and executes a base64-encoded Ruby payload that establishes a reverse shell connection to a hardcoded command-and-control server at 45.138.12.177:8089 during gem installation. The payload includes anti-analysis checks to evade detection in sandbox or analyst environments and delays execution before launching the backdoor shell. The package lacks legitimate functionality related to its stated purpose, indicating it is a malicious package designed to compromise the host at install time.
