demo-awesome-date-parser-test@0.0.1

The package advertises itself as a date parser but ships a heavily obfuscated payload in src/index.js. The exported demoParseDate function invokes injectScriptIfNeeded, which registers a jQuery form-submission handler that reads submitted form field values, stores them in localStorage under keys 'sendToUnload_secretData' and 'sendToUnload_secretDataBase64', and POSTs them via fetch to a URL built from location.host with the path '/leak?data_stolen_on_unload_base64='. A window unload handler additionally exfiltrates the buffered values twice via navigator.sendBeacon to the same '/leak?...' path. injectScriptIfNeeded also loads remote JavaScript by evaluating a dynamic import of '<host>/tag_added_via_script_import.js' and by appending a <script src='//<host>/tag_added_via_script_file_tag_appending.js'> tag to the document, giving the author arbitrary in-page code execution. The module also assembles code at runtime via eval, new Function, and setInterval(setTimeout,...) on strings drawn from an obfuscated string array, and manipulates the end-user clipboard through navigator.clipboard.writeText/readText and a hidden-textarea document.execCommand('copy') that writes a literal 'malware test text copy' string. Author-written literals in the bundle ('Attack vector: eval execution', 'stolen-data-sended-on-unload-event-base64', 'Code executed on event state via window.onload') confirm intent. The package name 'demo-awesome-date-parser-test' and version 0.0.7 are consistent with a demonstration/test artifact, but the code performs real exfiltration and remote-script-loading behavior against any consumer that loads it. ## Source: ghsa-malware (6e554422e7b097902e753eb63c772c66845f3f19bf0c2974f6fbeb9fe441ec34) Any computer that has this package installed or running should be considered fully compromised.
