Uno degli sviluppatori di pacchetti JavaScript ha condotto un esperimento creando e pubblicando nel repository NPM il pacchetto \u00abeverything\u00bb, che include come dipendenze tutti i pacchetti esistenti nel repository. Per realizzare tale possibilit\u00e0, il pacchetto \u00abeverything\u00bb \u00e8 direttamente legato a cinque pacchetti \u00ab@everything-registry\/chunk-N\u00bb, che a loro volta si legano come dipendenze a oltre 3000 pacchetti \u00absub-chunk-N\u00bb, ognuno dei quali si collega a 800 pacchetti esistenti nel repository. <\/p>\n

La pubblicazione di \u00abeverything\u00bb su NPM ha avuto due effetti interessanti. In primo luogo, il pacchetto \u00abeverything\u00bb \u00e8 diventato uno strumento per condurre attacchi DoS, poich\u00e9 il tentativo di installarlo porta al download di milioni di pacchetti presenti su NPM, esaurendo lo spazio su disco disponibile o fermando i processi di building. Statistiche indicano che il pacchetto NPM \u00e8 stato scaricato circa 250 volte, ma nessuno impedisce di aggiungerlo come dipendenza a un altro pacchetto dopo l'hacking dell'account dello sviluppatore per eseguire una diversion. Inoltre, alcuneplici servizi e strumenti che monitorano e verificano nuovi pacchetti pubblicati su NPM sono stati involontariamente colpiti. <\/p>\n

In secondo luogo, la pubblicazione del pacchetto \u00abeverything\u00bb ha di fatto bloccato la possibilit\u00e0 di rimuovere qualsiasi pacchetto in NPM che si trovava nella lista delle sue dipendenze. Un pacchetto su NPM pu\u00f2 essere rimosso dall'autore solo se non \u00e8 pi\u00f9 utilizzato come dipendenza da altri pacchetti, ma dopo la pubblicazione di \u00abeverything\u00bb, le dipendenze hanno coperto tutti i pacchetti nel repository. \u00c8 interessante notare che la rimozione dello stesso pacchetto \u00abeverything\u00bb \u00e8 stata anch'essa bloccata, poich\u00e9 9 anni fa nel repository \u00e8 stato pubblicato un pacchetto di test \u00abeverything-else\u00bb, in cui era specificata la stringa \u00abeverything\u00bb nella lista delle dipendenze. Pertanto, dopo la pubblicazione, il pacchetto \u00abeverything\u00bb si \u00e8 trovato nelle dipendenze di un altro pacchetto.
