What to do

Remove dolyame-ui-progressline 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 dolyame-ui-progressline version 35.8.1 contains malicious code that, upon being required, downloads and executes platform-specific binaries from hardcoded Cloudflare Workers endpoints or via DNS TXT record fallback. The payload is saved to temporary locations with deceptive names, given executable permissions, and executed detached from the main process. The package masquerades this behavior as telemetry functionality, but no legitimate telemetry occurs. The code uses string concatenation to obfuscate hostnames and API references to evade static detection. There is no official patch or fix currently documented.

Impact

This malicious package can execute arbitrary code on the host machine during installation or runtime by downloading and running remote binaries. This behavior can lead to full system compromise, unauthorized access, data theft, or further malware deployment. The deceptive naming and obfuscation techniques hinder detection by static scanners. There is no indication of active exploitation in the wild yet, but the impact of successful execution is severe.

Defensive guidance

Users and organizations should avoid using dolyame-ui-progressline version 35.8.1. Remove the package from any environments where it is installed. Employ supply chain security measures such as verifying package integrity, using trusted package sources, and monitoring for suspicious network activity related to package installations. Monitor vendor advisories for any future updates or patches.

Summary

The dolyame-ui-progressline npm package version 35.8.1 includes malicious functionality triggered on require. It loads a shim script that fetches a platform-specific binary from hardcoded Cloudflare Workers URLs or a DNS TXT record fallback, writes it to a temporary file with a deceptive name, sets executable permissions, and executes it detached from the main process. A secondary dropper path in the telemetry module decodes base64 chunks fetched via DNS TXT fallback, writes an extension to disk, sets permissions, and executes it if the primary shim fails. The code obfuscates critical strings by concatenation to evade static analysis. The package falsely claims to provide telemetry with opt-out tokens but performs no legitimate telemetry, only remote binary retrieval and execution on the host.
