What to do

Remove devplatform-spa-use-track 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 devplatform-spa-use-track version 35.5.3 contains malicious code that downloads and executes a platform-specific binary from attacker-controlled hosts. This behavior is hidden behind obfuscation techniques such as runtime string assembly and dynamic require calls. The package's intended function as a simple SPA tracking helper does not justify this behavior. The malicious binary is saved to temporary directories with disguised filenames, given executable permissions, and launched detached from the main process. An additional telemetry.js file in the package contains similar malicious dropper functionality. The executed payloads are opaque and unverified, posing a significant risk to users who install this package.

Impact

Installation and use of devplatform-spa-use-track version 35.5.3 can lead to arbitrary code execution on the host system due to the download and execution of attacker-controlled binaries. This can compromise system integrity, confidentiality, and availability. The malicious payloads are executed with user-level permissions and run detached from the main process, making detection and mitigation more difficult. The presence of multiple payload delivery mechanisms increases the likelihood of successful exploitation.

Defensive guidance

Users should immediately avoid installing or using devplatform-spa-use-track version 35.5.3. Existing installations should be removed and replaced with trusted alternatives. Monitor for any suspicious processes or files matching the described patterns in temporary directories. Consider blocking network access to the identified malicious domains and Cloudflare Workers hosts to prevent payload download.

Summary

The devplatform-spa-use-track npm package version 35.5.3 includes malicious code that, upon require(), loads a polyfill script which fetches a platform-specific binary from multiple attacker-controlled Cloudflare Workers hosts with DNS TXT fallback to additional malicious domains. The binary is saved to temporary directories with disguised names, permissions are set via a dynamically computed chmodSync call, and the binary is executed detached using shell commands. The package also contains a telemetry.js file with independent dropper code using the same techniques. The package's advertised purpose as a trivial SPA tracking helper does not require any such behavior, indicating clear malicious intent. The payloads are opaque and unverified, and the hosts are mutable and publisher-mismatched, increasing the risk of arbitrary code execution on affected systems.
