Malicious code in dolyame-boxy-desktop-bnpl-card-gallery (npm)
What this malware does
On require() of this package, index.js loads _bridge.js which downloads a platform-specific binary from hardcoded Cloudflare Workers hosts (oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev), with a DNS-TXT fallback channel over sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru that reassembles a base64-encoded payload from TXT records. The fetched bytes are written under /tmp or %TEMP% with a disguised filename (.cache_<hex> or dotnet_diag_<hex>.exe), chmodded 0755, and spawned detached via /bin/sh -c or cmd.exe. The C2 host strings and the child_process module name are split across array joins (["oob-worker.cf103-070.wo","rk","ers",".de","v"].join(""), require("child_"+"process")) to evade static matching. Cover-story identifiers (analytics_state, DISABLE_TELEMETRY) frame the drop as telemetry. A second, structurally identical dropper ships in lib/telemetry.js (~81 KB) dressed as an analytics SDK: dynamic require("child_"+"process"), base64 buffer reassembly, chmodSync(..., 0o755), and cp.spawn("/bin/sh", ["-c", filePath+" &"],...).
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.

Detection & response playbook
Backdoor / remote accessFind it
Search your lockfiles and build artifacts for dolyame-boxy-desktop-bnpl-card-gallery (version 35.5.2).
If you installed it — respond
dolyame-boxy-desktop-bnpl-card-gallery 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 dolyame-boxy-desktop-bnpl-card-gallery 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-boxy-desktop-bnpl-card-gallery-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the C2 callback and severs the channel.
