Classification

Malicious package

Published to npm · OSV MAL-2026-6726

What to do

Remove db-convertor from every project, lockfile and image that pulls it in. Treat any host that installed it as compromised: rotate the credentials, tokens and keys it could read, from a clean machine.

Description

The npm package 'db-convertor' contains malicious code that fetches and executes attacker-controlled JavaScript code from an anonymous mutable paste service at runtime. This behavior is hidden behind base64 encoding and is undocumented, increasing the risk of accidental installation by users mistyping the legitimate 'dx-db-connector' package name. Execution of the fetched code occurs without any validation, allowing arbitrary code execution within the Node.js process. Systems with this package installed should be considered fully compromised.

Impact

Any system with this package installed or running is considered fully compromised. The attacker can execute arbitrary code with the privileges of the Node.js process, potentially leading to full system compromise. All secrets and keys stored on the compromised system should be considered exposed and must be rotated immediately from a secure environment. Removal of the package alone does not guarantee elimination of all malicious artifacts or backdoors introduced by the attacker.

Defensive guidance

Immediate removal of the 'db-convertor' package is required. All credentials, secrets, and keys stored on the affected system should be rotated from a separate, uncompromised environment. Due to the high likelihood of full system compromise, a full forensic investigation and system rebuild are recommended.

Summary

The 'db-convertor' npm package exports a class with a method that base64-decodes a hardcoded URL pointing to a JSON paste on jsonkeeper.com. It retrieves a 'session' field from this JSON via axios and pipes the content as stdin into a detached Node.js child process, executing arbitrary attacker-controlled code. The use of an anonymous mutable paste host means the payload can be changed at any time, enabling ongoing remote code execution. The package name and keywords impersonate the legitimate Divblox 'dx-db-connector' package, increasing the likelihood of accidental installation. This backdoor is not documented and is designed to evade casual code review and string scanning.
