devplatform-tablenpm

On require() of devplatform-table, index.js loads./compat which selects a platform-specific payload path, downloads an executable from string-concatenation-obfuscated Cloudflare Workers hosts (reconstructed from fragments such as ["oob-worker.cf103-070.workers.d","ev"].join("")) with a DNS-TXT fallback via *.dl.wel1.ru, writes it to /tmp or %TEMP% under disguised names (.cache<hex>, dotnet_diag_<hex>.exe), chmods it 0755, and spawns it detached via /bin/sh -c or cmd. Sensitive API identifiers including 'child_process' and 'chmodSync' are also reassembled at runtime from fragments to evade static analysis. The fetched binary is unpinned, unverified, and comes from anonymous worker hosts unrelated to any package publisher domain, giving whoever controls those hosts arbitrary code execution on any machine that installs or imports this package.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
