The script downloads a gzip carrier from amplify-gursha-dev-121835-deployment.s3.amazonaws.com to /tmp/.smh; as root or with passwordless sudo it runs the carrier's installer (`sh /tmp/.smi agent`), which installs an XMRig miner plus two helper daemons under random system-component names and persists them as systemd units or @reboot cron entries, and otherwise it extracts the bundled XMRig binary to ~/.local/lib/<random name>/ and mines Monero to networkservicesupp.flashhub.net:8443 over TLS with a hardcoded wallet. The npm account walknpm published the same scripts/miner.sh in @walknpm/todo-cli@2.0.1 within 27 seconds of this version on 2026-10-26, and it is byte-identical to the one in @sudobility/testomniac_client (MAL-2026-18129).\n\n---\n_-= Per source details.

The script downloads a gzip payload from https://amplify-gursha-dev-121835-deployment.s3.amazonaws.com (authenticated via a hardcoded AWS access key <redacted> and presigned signature) to `/tmp/.smh`, decompresses it to `/tmp/.smi`, and executes it. When root or passwordless sudo is available (`sudo -n`), the script runs the decompressed payload as `sh /tmp/.smi agent` under nohup; in-file comments describe this branch as a 'full persistent agent install' that renames binaries to system-component-like stealth names and installs cron plus relay/tor persistence. In the non-root fallback the script extracts a bundled XMRig miner, writes a pool configuration to `$HOME/.sysmond.json` targeting networkservicesupp.flashhub.net:8443, stages the miner under `$HOME/.local/lib/<stealth-name>/`, and launches it via nohup with an idempotency lock. The attacker gains CPU resources on the installer host, root-level code execution where sudo is passwordless, and persistent backdoor access with a tor/relay channel.\n\n## Source: ossf-package-analysis (ae55a6a112dc0b823afa1c7c0217871c1c19b5d0b77fde2a8ec29d4b26a9549b)\nThe OpenSSF Package Analysis project identified 'dsh-plugin-blender-3d' @ 0.2.1 (npm) as malicious.\n\nIt is considered malicious because:\n\n- The package executes one or more commands associated with malicious behavior.\n","state":0,"publishedAt":"2026-10-26T00:55:34+00:00","modifiedAt":"2026-10-26T06:45:15.0245464+00:00","affected":[{"ecosystem":"npm","name":"dsh-plugin-blender-3d","ranges":[],"versions":["0.2.1"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/dsh-plugin-blender-3d","https://osv.dev/vulnerability/MAL-2026-18129","https://www.npmjs.com/package/dsh-plugin-blender-3d/v/0.2.1"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-18321","license":"OSV · upstream source license applies","key":"osv:MAL-2026-18321","identifiers":["MAL-2026-18321"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
