On require "zzhelloworld_socktest", the library's top-level module body opens a TCP connection to the hardcoded remote endpoint 66.78.40.218:32768, reopens STDIN, STDOUT, and STDERR onto that socket, and execs /bin/sh -i. Loading the gem gives the operator of that remote host an interactive shell on the installing machine, with no authentication and full process privileges. The gem's stated purpose is a trivial test library, which does not match a remote-shell capability. The destination is a bare IPv4 address unrelated to any declared publisher infrastructure.
