Description

The npm package dolyame-ui-scroll version 35.4.3 contains malicious code that downloads and executes opaque binaries from author-controlled Cloudflare Workers subdomains or via a DNS-TXT covert channel. This behavior is unrelated to the package's stated UI components purpose and involves no signature or hash verification of the downloaded payloads.

Impact

The malicious code enables arbitrary binary execution on the host system without user consent or verification, potentially allowing attackers to execute any code, compromise system integrity, exfiltrate data, or establish persistence. The lack of signature or hash verification increases the risk of executing malicious payloads. This represents a severe supply chain compromise risk for users of this package version.

Defensive guidance

Users should immediately avoid using dolyame-ui-scroll version 35.4.3 and remove it from their environments. Monitor vendor advisories or repository sources for updates or official patches. Employ supply chain security best practices such as verifying package provenance and using tools to detect malicious packages.

Summary

The dolyame-ui-scroll npm package (version 35.4.3) includes malicious functionality in its _init.js file. Upon requiring the package, it dynamically selects a platform-specific asset and downloads an opaque binary over HTTPS from a set of rotating Cloudflare Workers subdomains controlled by the attacker. The hostnames are reconstructed at runtime to evade static detection. The binary is saved to temporary directories with disguised filenames, permissions are set to executable, and it is launched detached via shell commands. If the HTTPS download fails, the package falls back to retrieving a base64-encoded payload via DNS-TXT records from *.dl.wel1.ru subdomains, reconstructs the binary, and executes it. No integrity checks are performed on the downloaded payloads. This fetch-and-execute behavior is unrelated to the package's declared purpose as a UI component library.
