The devplatform-i18n package published on npm, specifically version 35.6.2, is a malicious package masquerading as an internationalization library. Its main entry point requires a setup script that dynamically selects a payload based on the platform and fetches executable bytes from multiple obfuscated remote hosts over HTTPS and DNS TXT record chunks. These payloads are written to temporary directories on Unix or Windows systems, permissions are set to executable, and the payloads are spawned detached from the parent process. The package uses obfuscation techniques such as array joins and string concatenation to conceal API calls like child_process and fs.chmodSync, as well as the remote hosts and filenames. This results in unauthorized remote code execution on the host system.

This malicious package enables remote code execution by downloading and executing arbitrary payloads on the victim's machine. The execution is done in a detached manner, allowing persistence and evasion of detection. The obfuscation and use of multiple delivery mechanisms complicate detection and analysis. There is no indication of known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix or removal is confirmed, users should avoid using devplatform-i18n version 35.6.2 and remove it from their environments if present. Monitoring for unusual child process executions and network connections to the specified domains may help detect infections.
