Malicious code in autotel-mongoose (npm)

T1195.002 · Compromise Software Supply Chain

Analysis

This version is part of a supply-chain compromise of the autotel publisher pipeline. The release shows a sudden ~23x size increase (from ~205KB to ~4.7MB) carrying a ROT13/ROT-cipher eval decoder that injects and executes a hidden payload on module import (require-time), with no install hook needed. The affected releases were later deprecated with the note "SECURITY: compromised supply-chain build."
