The package's advertised getTransactions() API invokes an internal loader that reads database.js — a file disguised as a product catalog — extracts each record's mark field, base64-decodes it and applies a per-byte Caesar shift, concatenates the result into a code string, and passes it to the Function constructor together with Buffer, require, and process. This yields arbitrary Node.js execution with full filesystem, network, and child_process capabilities on the caller's host whenever the documented API is used. index.js hides the sink by reconstructing the identifiers 'setTimeout', 'Function', 'Buffer', 'require', and 'process' from a split string-array and by resolving the Function constructor indirectly via globalThis.constructor.constructor. The multi-layer obfuscation (identifier reassembly, indirect constructor lookup, base64+Caesar-encoded payload, JSON-shaped carrier file, deferred setTimeout) has no legitimate purpose for a package presented as a transactions helper and is the concealment layer of a supply-chain 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.
