## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

dist/index.js appends a heavily obfuscated obfuscator.io-style payload (string array \_0x240a of length 303, decoder \_0x4963, string-array rotation) after the clean TypeScript-compiled validation code. None of this obfuscated code is declared in dist/index.d.ts and it executes at top level on \`import '@wizloft/harness-validation'\`. Decoded string fragments include Ethereum RPC / block-explorer hostnames (\`h.drpc.org\`, \`pc.io/eth\`, \`stapi.io\`), a hardcoded attacker Ethereum address (\`0xa322E5f3...\`), Etherscan-style query parameters (\`?module=account\`, \`filterby=from\`), a spoofed browser User-Agent, and \`application/json\` / \`content-encoding\` request framing. The payload queries the block explorer for transactions from the hardcoded wallet, extracts a URL/payload from the transaction data, then fetches and executes the resolved content — a blockchain-based dead-drop that lets the publisher rotate the delivered code by posting a new transaction from that wallet, giving them a persistent mutable remote-code channel against every process that imports the library. Sibling packages in the @wizloft/\* namespace (@wizloft/harness-evidence, @wizloft/harness-kernel) are declared dependencies at matching alpha versions and exhibit the same trojanized-library shape.
