Source: amazon-inspector (affe0f39dc539ebc88bb056595ac821969f59fbe3430c5e1465178396b5812e0) Package m98th version 0.0.0-stage contains two files with no detected malicious behavior. No lifecycle scripts, no network calls to attacker-controlled destinations, no credential or environment reads, no filesystem persistence, no obfuscated payloads, and no install-time or import-time code execution were observed. The 0.0.0-stage version string is consistent with a staging or placeholder release.

All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
