Advisory PublishedCVSS 9.6/10
This repository is a classic trojanized dotenv-clone with a 72-hour time-delayed payload designed to evade sandbox analysis. The package masquerades as a legitimate dotenv alternative ('Lightning-fast environment variable loader') and was published 2 days before scanning by a brand-new account with a single package.
After the delay, the `activate()` function collects a full system fingerprint (hostname, platform, architecture, CPU count, memory, home directory, network interfaces, SSH key presence in ~/.ssh, .npmrc presence, and a regex scan of environment variable names for secrets like 'key', 'token', 'password', 'wallet', 'seed', 'mnemonic') and POSTs it as JSON to the hardcoded C2 at 2.27.62.51:8080/api/health. The payload then establishes a persistent 6-hour heartbeat loop, meaning the exfiltration continues for as long as the process runs.
