Decoded strings in the appended segment include Ethereum JSON-RPC and block-explorer endpoints (drpc.org, publicnode.com, blockscout, an etherscan-style txlist/account API), a hardcoded mixed-case ETH address prefix 0xa322E5f3..., a forged Chrome User-Agent, brotli/gzip decompression, AbortController-based fetch, and a custom /0x/ls exfil path with x-payload-* headers. The payload runs at module load whenever a consumer imports the package and has no relationship to the advertised purpose of reading repository files for a harness runtime. Only the trailing segment is obfuscated; the legitimate plugin portion is plain ESM, indicating a hostile payload smuggled onto an otherwise-clean plugin build.\n\n## Source: ghsa-malware (ae765bf0c1093d37cd57625b348fba8911e92e729a2d895a58f6a0fa25903824)\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.
