Description

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (8e9cb745c0771868eb6908cf1c783614da3e41fe1d1cf52b4d2d04705c51af19) On require of the package's main, index.js side-loads _runtime.js which selects a per-platform payload path, fetches an opaque binary from string-split obfuscated Cloudflare Workers hosts (oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev), writes it to /var/tmp or %TEMP% with a disguised filename (`.cache_<hex>`, `dotnet_diag_<hex>.exe`, `.analytics_state`), chmods 0755, and spawns it detached via child_process.spawn('/bin/sh') or spawn('cmd'). When the HTTPS mirrors fail, _runtime.js falls back to a DNS TXT covert channel: it resolves `c.<domain>` for a chunk count, iterates `<i>.dl.well1.site` TXT records (tin/tina/ldr/win subdomains), concatenates and base64-decodes them into the payload, then writes and spawns it. Host names, fallback DNS domains, and the string 'child_process' are assembled from split string arrays at runtime to evade static analysis. There is no version pinning, hash check, or signature verification, and the destinations are not the publisher's infrastructure. Cover-story framing as an 'Analytics SDK' with a DISABLE_TELEMETRY opt-out does not match the actual fetch-decode-write-chmod-spawn behavior. ## Source: ghsa-malware (e476a87c0e4538a947633f4bd6a61d856208adab0161811adf5ae087c9b02915) 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.

Impact

This malicious package can execute arbitrary binary payloads on the host system by downloading and running code from attacker-controlled infrastructure. This can lead to unauthorized code execution, potential system compromise, and persistence. The use of covert DNS channels for payload delivery increases stealth and complicates detection. The lack of integrity checks and external payload sources heightens risk. The disguised filenames and detached execution further aid evasion of detection and analysis.

Defensive guidance

Users should avoid using version 20.3.3 of dolyame-boxy-atom-bnpl-email-form. Remove the package from affected systems and replace it with trusted alternatives. Monitor for suspicious child processes spawned from npm packages.

Summary

The npm package dolyame-boxy-atom-bnpl-email-form version 20.3.3 includes a malicious runtime script (_runtime.js) that dynamically selects a platform-specific payload path and fetches an opaque binary payload from multiple obfuscated Cloudflare Workers domains. This payload is saved to system temporary directories under disguised filenames, permissions are set to executable (chmod 0755), and the payload is executed detached via child_process.spawn using shell commands. If HTTPS-based payload retrieval fails, the package falls back to a covert DNS TXT record channel, resolving specific domains to retrieve base64-encoded payload chunks, which are concatenated, decoded, written, and executed similarly. The package attempts to evade static analysis by assembling hostnames, fallback domains, and critical strings like 'child_process' at runtime from split string arrays. No integrity checks such as version pinning, hash verification, or signature validation are present, and the payload sources are external and unrelated to the publisher. The package falsely advertises itself as an Analytics SDK with a telemetry opt-out, which does not align with its actual behavior.
