dolyame-ui-inputdatenpm
Advisory published Updated
dolyame-ui-inputdate is a confirmed malicious npm package (MAL-2026-13577) that executes malicious code on install (malicious version 35.8.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in dolyame-ui-inputdate (npm)
What this malware does
On require()/import, index.js loads./ext.js which selects a platform-specific remote endpoint, downloads an opaque binary via HTTPS from string-split-obfuscated Cloudflare Workers hosts (oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev), with a base64-over-DNS-TXT fallback channel across sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru. The downloaded bytes are written to a hidden temp file (.cache<rand> / dotnet_diag_<rand>.exe), chmod 0755, and spawned detached via /bin/sh -c or cmd. Hostname reconstruction from split-string arrays and the DNS covert-channel fallback demonstrate deliberate evasion. The package's stated purpose ('API client wrappers') does not correspond to any of this behavior.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for dolyame-ui-inputdate (version 35.8.1).
If you installed it — respond
Remove dolyame-ui-inputdate from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If dolyame-ui-inputdate was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks dolyame-ui-inputdate-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
