The shipped source is largely a copy of pino with an extra file `lib/contract.js` wired in. `pino.js` exports `chain`, whose body calls `contract()`, so `require('pino-testkit')(...)` reaches the added file at load/call time. `lib/contract.js` uses a deterministic Fisher-Yates-style shuffle plus character substitution (`\\x25`, `\\x23\\x30`, `\\x23\\x31`) to reconstruct the string `Function` and pluck `Function` off a captured global (`ype[OUN]`), then builds a new function from a second decoded body and immediately invokes it (`cMp(7746)`). Before doing so it hoists `require` and `module` onto `global`, so the dynamically constructed code can pull arbitrary further modules. Obfuscation of an executable payload combined with dynamic Function-constructor execution and require/module hoisting in a package that presents itself as `pino` is the canonical typosquat-dropper shape, giving the publisher arbitrary code execution on any consumer that requires or uses this package.\n\n## Source: ghsa-malware (a263213f07071bf62a6f4fdb9c258b1e3cf70735f006d9dd6e7407e4107a42ff)\nAny computer that has this package installed or running should be considered fully compromised.
