Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-12330/ (Markdown: https://insights.sbomify.com/MAL-2026-12330/index.md)","id":"MAL-2026-12330","markdown":"https://insights.sbomify.com/MAL-2026-12330/index.md","name":"MAL-2026-12330","record":{"aliases":["GHSA-rx4f-8493-c7j8"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"build/index.js appends an eval(atob('...')) block that fires when the module is required. The decoded payload queries Ethereum JSON-RPC endpoints (eth.blockscout.com, 1rpc.io/eth, eth.drpc.org, blastapi.io) for transactions from a hardcoded attacker wallet (0xa322E5f3D311D3080e6f01210639aDC2490Ef1a), reconstructs an IPv4 address from the bytes of tx.to, then fetches http://\u003cresolved-ip\u003e:443/0x/cls and http://\u003cresolved-ip\u003e:443/0x/ls. The response body is XOR-decoded with a hardcoded key and executed via eval() and a detached spawn('node','-e',...) child process (detached:true, stdio:'ignore', windowsHide:true, unref()). The C2 endpoint is mutable — the attacker rotates it by publishing new on-chain transactions from the controlled wallet — giving persistent remote code execution on any machine that imports the library. All require targets, URLs, HTTP header/method names, and error strings in the appended region are written as \\u00XX unicode escapes and wrapped in base64+atob+eval; the legitimate __exportStar re-exports above the appended block are plain text, so the sole obfuscated region is the loader.\n\nAny 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.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in @vboxdev/common (npm)","id":"MAL-2026-12330","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":[],"package":"@vboxdev/common","purl":"pkg:npm/%40vboxdev/common","source":"MAL-2026-12330"}],"products":null,"published":"2026-08-05","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-12330/"}
