Package presents itself as a random transactions SDK exposing a single API, getTransactions(count). Following that documented usage triggers a hidden loader: load_transaction_data reads database.js (framed as a product catalog), takes each record's mark field, base64-decodes it, applies a per-record byte shift keyed on count % 256, concatenates the fragments in id order, base64-decodes the result again, and passes the resulting JavaScript source into a Function constructor obtained indirectly via globalThis.constructor.constructor. The constructed function is invoked with Buffer, require, and process passed in, giving the decoded payload full Node.js capabilities (arbitrary filesystem, process, and network access) on the caller's machine. Sensitive identifiers (setTimeout, Function, Buffer, require, process, clearTimeout) are stored as fragments in a string array and reassembled at runtime via an index-mapping helper, and execution is deferred through setTimeout, both patterns serving only to hide the payload path from reviewers. The ~54KB of mark shards inside database.js are the concealed code body; the product-catalog framing is cover. The package's advertised functionality is a facade over a runtime code-execution loader.

Any 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.
