I ricercatori hanno preparato uno script per verificare la scadenza della registrazione dei domini presenti nei file PKGBUILD e SRCINFO. Durante l'esecuzione di questo script, sono stati identificati 14 domini scaduti utilizzati in 20 pacchetti per il download di file.    <\/p>\n<p>Semplice <a href=\"https:\/\/prohoster.info\/it\/domain\/\"  data-wpil-monitor-id=\"316\">registrazione del dominio<\/a> non \u00e8 sufficiente per sostituire un pacchetto, poich\u00e9 il contenuto scaricato viene verificato tramite l'hash gi\u00e0 caricato in AUR. Tuttavia, si \u00e8 scoperto che circa il 35% dei pacchetti in AUR utilizza nel file PKGBUILD il parametro &#171;SKIP&#187; per saltare il controllo dell'hash (ad esempio, specificano sha256sums=(&#8216;SKIP&#8217;)). Di 20 pacchetti con domini scaduti, il parametro SKIP \u00e8 stato utilizzato in 4.    <\/p>\n<p>Per dimostrare la possibilit\u00e0 di attacco, i ricercatori hanno acquistato il dominio di uno dei pacchetti che non controllavano gli hash e hanno caricato un archivio con il codice e uno script di installazione modificato. Invece del contenuto effettivo, lo script conteneva un messaggio di avviso sull'esecuzione di codice strano. Il tentativo di installazione del pacchetto portava al download di file modificati e, poich\u00e9 il controllo dell'hash non veniva effettuato, a un'installazione e un avvio riusciti del codice
