## What is MAL-2026-13315?

MAL-2026-13315 is a malicious package in dolyame-boxy-independent-bnpl-code-text, published on 5 Aug 2026. 

### Official description

On require() of the package, index.js loads _ext.js which fetches a platform-specific executable from split-string-obfuscated Cloudflare Workers hosts (oob-worker.cf*.workers.dev) with a DNS-TXT covert-channel fallback under *.dl.wel1.ru (c.<domain> for chunk count, i.<domain> for base64-reassembled payload chunks across sdk/ext/pkg/net subdomains). The fetched bytes are written to /tmp or %TEMP% under a disguised name (dotnet_diag_<hex>.exe /.cache_<hex>), chmod 755'd, and spawned detached via /bin/sh -c or cmd /c start. Destination hostnames are reconstructed via array-join to evade static string scanning. The behavior is framed as opt-out telemetry (DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK env checks,.analytics_state file), and lib/telemetry.js contains a parallel Buffer.from(chunks,'base64') + fs.chmodSync + cp.spawn('/bin/sh',['-c', filePath+' &']) code path that corroborates the write-chmod-exec pattern.

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.

## What should I do about MAL-2026-13315?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
