Vulnetix · Advisory published April 27, 2026

Executes arbitrary attacker-controlled JavaScript at install time via a preinstall hook that fetches http://analytics-client.sbt-gitverse.oob.moika.tech/poc.js and eval()s the response body. Targets the @sbt_gitverse npm scope used by Sberbank GitVerse. Preinstall.js is identical (SHA256 a70b77c6...) across three sibling campaign packages. Stage-2 payload poc.js (SHA256 8c3a2b983b2ce15fc3d1379bdb437f67843313a2c6a8d9d0a112ceb3b409fe96, 3323 bytes) served from 72.56.97.200 at http://analytics-client.sbt-gitverse.oob.moika.tech/poc.js collects whoami, hostname, ifconfig, /etc/passwd, and /etc/hosts, then exfiltrates base64-encoded via HTTP GET to a victim-specific subdomain on oob.moika.tech.
