bpm-foundation-base-configsnpm
Advisory published Updated
bpm-foundation-base-configs is a confirmed malicious npm package (MAL-2026-13105) that opens a backdoor for remote access (malicious version 35.6.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in bpm-foundation-base-configs (npm)
What this malware does
On require, index.js loads _helpers.js, which reconstructs C2 hostnames via string-split-join concatenation (['oob-w','orker.cf101-adf.worke','rs','.d','ev'].join('') and similar), selects a platform-specific payload, fetches an opaque binary from those hidden hosts over HTTPS, writes it to /tmp or the Windows temp directory under a disguised filename (dotnet_diag_*.exe / .cache_*), chmods it 0755, and spawns it detached via /bin/sh or cmd.exe (_helpers.js line 125+). If HTTPS retrieval fails, loadViaDns falls back to a DNS-TXT covert channel: it queries c.<domain> for a chunk count then walks 0.<domain>..N.<domain> TXT records (resolver domain reconstructed as ['sdk.dl.we','l1.r','u'].join('')), concatenates the values, base64-decodes them into the executable buffer, and executes through the same write+chmod+spawn sink. No hash or signature verification is performed and the destination hosts have no relationship to the declared package purpose. The behavior fires purely from require() of the package.

Detection & response playbook
Backdoor / remote accessFind it
Search your lockfiles and build artifacts for bpm-foundation-base-configs (version 35.6.2).
If you installed it — respond
bpm-foundation-base-configs establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.
Did it already run?
If bpm-foundation-base-configs 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 bpm-foundation-base-configs-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the C2 callback and severs the channel.
