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-2026-14290/ (Markdown: https://insights.sbomify.com/MAL-2026-14290/index.md)","id":"MAL-2026-14290","markdown":"https://insights.sbomify.com/MAL-2026-14290/index.md","name":"MAL-2026-14290","record":{"aliases":["GHSA-7fvf-fgwq-85q6"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"bin/install/install.js appends a heavily obfuscated top-level IIFE (obfuscator.io-style rotated string array `_0x240a`/`_0x4963` with arithmetic index decoding) after the benign install() helper. The payload queries public Ethereum RPCs and etherscan.io for transactions from the hardcoded sender address 0xa322E5f3..., decodes the transaction `to` field as an IPv4 address, fetches an XOR-encrypted body from that host, and executes it via `eval(prefix+xor(body))` and a detached `spawn('node', ['-e',...], {detached:true}).unref()`. The package's main entry (bin/index.js) unconditionally requires./install/install, so the IIFE runs whenever the package is required or the CLI is invoked. The attacker controls the fetched payload by publishing new Ethereum transactions from the sender address; there is no version pinning, no signature check, and the destination host rotates on-chain. Decoded strings inside the string array include `eth_getBlockByNumber`, `etherscan.io`, `eval`, and `spawn`.\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.
