Description

The npm package 'augustdigital-sdk' version 8.20.1 is a malicious repackaging of the legitimate '@augustdigital/sdk' package. It includes a hidden postinstall script that silently sends system information such as hostname, username, and working directory to an attacker-controlled Cloudflare Workers endpoint. This data exfiltration occurs automatically during installation without user consent or disclosure. No additional malicious payloads or credential theft mechanisms were found in the package.

Impact

Hosts that install the malicious 'augustdigital-sdk' package version 8.20.1 leak identifying system information—hostname, username, and working directory path—to an attacker-controlled endpoint. This disclosure can aid attackers in reconnaissance and profiling of compromised environments. No direct code execution or credential theft beyond this information leakage is indicated.

Defensive guidance

Users should avoid installing the unscoped 'augustdigital-sdk' package and instead use the legitimate scoped package '@augustdigital/sdk'. Since this is a malicious package impersonation, remediation involves removing the malicious package from affected systems and verifying no further compromise occurred. Users should audit their package sources and prefer scoped, verified packages from trusted maintainers.

Summary

The 'augustdigital-sdk' npm package is an unscoped brand-hijack of the legitimate '@augustdigital/sdk' package. Version 8.20.1 is a byte-for-byte copy of the genuine release but with an added unconditional postinstall hook. This hook executes a Node.js inline script that sends a JSON payload containing the host's OS hostname, user information username, current working directory, package name/version, and a timestamp to a Cloudflare Workers subdomain impersonating build/CDN infrastructure. The data exfiltration is silent and has no opt-out. No further malicious code or credential-stealing functionality was detected in the package contents.
