## Source: amazon-inspector (4344ab16d08a7e38ea2f32b406453f86d792c0fa17103125ad84ffd0e39c187f) 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. --- Credit: OpenSSF (source)

03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
