{"schema_version":"1.9.0","id":"MAL-2026-18321","published":"2026-10-26T00:55:34Z","modified":"2026-10-26T06:45:15.024546442Z","summary":"Malicious code in dsh-plugin-blender-3d (npm)","details":"dsh-plugin-blender-3d@0.2.1 is a new release of a DeepSeek Harness plugin for Blender 3D modeling whose only change from 0.2.0 is a postinstall script, `sh scripts/miner.sh`, that runs on npm install. 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","affected":[{"package":{"name":"dsh-plugin-blender-3d","ecosystem":"npm","purl":"pkg:npm/dsh-plugin-blender-3d"},"versions":["0.2.1"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"scripts/miner.sh","sha256":"50df05975352cfa4558892d0a9ab493744c8ddd40948efa6755bb11dc5050118","tlsh":"2371b7a5e4644b3471ac667d369e72815d92443f06213a61f0efef30ab2d46e20a81b7"}],"package_integrity":[{"filename":"dsh-plugin-blender-3d-0.2.1.tgz","hashes":{"sha1":"d6d24035635f80db7ed8432a0f2517ff324efb2c","sha512_sri":"sha512-IdIxjq1X3RB6pL2JCv8xXZXnq4ZtzxVX4SdFbPxfkMrP6Ia09noVceeUq4a3Nhcg+44pnC6Hsb5fzga5gUe7ow=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/dsh-plugin-blender-3d/MAL-2026-18321.json"}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dsh-plugin-blender-3d"},{"type":"WEB","url":"https://osv.dev/vulnerability/MAL-2026-18129"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/dsh-plugin-blender-3d/v/0.2.1"}],"database_specific":{"iocs":{"domains":["networkservicesupp.flashhub.net"],"files":[{"digests":{"sha256":"c0bd8bff2b17e5ed34b005d5107ea3ea4345b605376a1e85d736c33ed5ab69da"},"note":"Stage two gzip carrier from the S3 URL (11,334,678 bytes), unpacked to /tmp/.smi.","paths":["/tmp/.smh"],"source":"DROPPED"},{"digests":{"sha256":"4f8bf0f86d0bedc39af0ee2ae74548bffc26a7b1a285a2c0acdcc91613a71f03"},"note":"Self-extracting installer (VERSION 20261017, modes agent/keepalive/relay/status/stop/start/update/uninstall) with a base64 tar payload after __PAYLOAD__.","paths":["/tmp/.smi"],"source":"DROPPED"},{"digests":{"sha256":"39ef74e9d616b7a4fd25e12b04631d0b6d8fa50c04547e88304b358b40cc46c6"},"note":"bin/miner-linux-amd64 from the payload, an XMRig build (RandomX); config written to ~/.sysmond.json, lock file /tmp/.sysmond.lock.","paths":["~/.local/lib/<random name>/<random name>","/usr/local/lib/<random name>/<random name>"],"source":"DROPPED"},{"digests":{"sha256":"f57ca57a038672aafdab478648c24b9f70b7059aa29d539f288129f0677c6a4c"},"note":"postinstall script runs `sh scripts/miner.sh`, the rig2 XMRig miner dropper (dsh-plugin-blender-3d@0.2.1).","paths":["package.json"],"source":"PACKAGE_ARCHIVE"},{"digests":{"sha256":"50df05975352cfa4558892d0a9ab493744c8ddd40948efa6755bb11dc5050118"},"note":"Executed by the postinstall script of dsh-plugin-blender-3d@0.2.1.","paths":["scripts/miner.sh"],"source":"PACKAGE_ARCHIVE"}],"urls":["https://amplify-gursha-dev-121835-deployment.s3.amazonaws.com/amplify-cfn-templates/cloud-backend-cache-20261019.gz"]},"malicious-packages-origins":[{"import_time":"2026-10-26T03:51:26.42105939Z","modified_time":"2026-10-26T01:01:24Z","sha256":"ae55a6a112dc0b823afa1c7c0217871c1c19b5d0b77fde2a8ec29d4b26a9549b","source":"ossf-package-analysis","versions":["0.2.1"]},{"id":"IN-MAL-2026-021762","import_time":"2026-10-26T06:39:40.992238828Z","modified_time":"2026-10-26T06:29:45Z","sha256":"08bd399ddec36950a4cb3c82cb8460e95cde40441f464fbff1d215f6a7f13937","source":"amazon-inspector","versions":["0.2.1"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"InvisiRisk, Inc.","contact":["https://www.invisirisk.com","mailto:research@invisirisk.com"],"type":"FINDER"},{"name":"OpenSSF: Package Analysis","contact":["https://github.com/ossf/package-analysis","https://openssf.slack.com/channels/package_analysis"],"type":"FINDER"}]}
