The obfuscated body contains `require`, `exec`, `spawn`, and `axios` tokens, indicating the decoded code drives child-process execution and outbound HTTP requests. Any consumer that imports `chai-as-deployer` triggers this payload with no further action. Author metadata is generic (`Harrison Thorn <harrisonthorn@protonmail.com>`, bugs URL `harrisonthorn.com`) and the package description is unrelated boilerplate. The combination of cover-story impersonation, no legitimate functionality, top-level require of a heavily obfuscated bundle, and shell+network primitives inside that bundle is the canonical shape of an import-time stealer/loader.\n\n## Source: ghsa-malware (cb63584d83487c7d7ce3b9d031d79502412fd048c2260a05b0a8ef98aa23ef59)\nAny computer that has this package installed or running should be considered fully compromised.
