Di solito, il type-squatting viene utilizzato per diffondere pacchetti dannosi contando sul fatto che lo sviluppatore distratto commetta un errore di battitura o non noti la differenza. Durante la ricerca sono stati identificati oltre 700 pacchetti, i cui nomi sono simili a quelli populati e differiscono per dettagli minori, ad esempio la sostituzione di lettere simili o l'uso di underscore invece di trattini. <\/p>\n<p>In pi\u00f9 di 400 pacchetti sono stati trovati componenti sospettati di comportamenti dannosi. In particolare, all'interno c'era un file aaa.png, contenente codice eseguibile nel formato PE. I suddetti pacchetti erano collegati a due account, attraverso i quali dal 16 al 25 febbraio 2020 sono stati pubblicati su RubyGems <noindex><a rel=\"nofollow\" href=\"https:\/\/blog.reversinglabs.com\/hubfs\/Blog\/ruby_malicious_gems.txt\">724 pacchetti dannosi<\/a><\/noindex>, che complessivamente sono stati scaricati circa 95.000 volte. I ricercatori hanno informato l'amministrazione di RubyGems e i pacchetti dannosi identificati sono stati gi\u00e0 rimossi dal repository. <\/p>\n<p>Tra i pacchetti problematici identificati, il pi\u00f9 popolare \u00e8 risultatol'&#171;atlas-client&#187;, che a prima vista \u00e8 praticamente indistinguibile dal pacchetto legittimo &#171;<noindex><a rel=\"nofollow\" href=\"https:\/\/rubygems.org\/gems\/atlas_client\">atlas_client<\/a><\/noindex>&#171;. Il pacchetto in questione \u00e8 stato scaricato 2100 volte (mentre il pacchetto normale \u00e8 stato scaricato 6496 volte, ovvero gli utenti si sono sbagliati quasi nel 25% dei casi). Gli altri pacchetti, in media, sono stati scaricati 100-150 volte e si sono camuffati sotto altri pacchetti utilizzando tecniche simili di sostituzione tra sottolineature e trattini (ad esempio, tra <noindex><a rel=\"nofollow\" href=\"https:\/\/blog.reversinglabs.com\/hubfs\/Blog\/ruby_malicious_gems.txt\">pacchetti dannosi<\/a><\/noindex>: appium-lib, action-mailer_cache_delivery, activemodel_validators, asciidoctor_bibliography, assets-pipeline, apress_validators, ar_octopus-replication-tracking, aliyun-open_search, aliyun-mns, ab_split, apns-polite).<\/p>\n<p>I pacchetti malevoli includevano un file PNG che, invece di un'immagine, conteneva un file eseguibile per la piattaforma Windows. Il file era stato creato utilizzando l'utilit\u00e0 Ocra Ruby2Exe e comprendeva un archivio autoestraente con uno script Ruby e un interprete Ruby. Durante l'installazione del pacchetto, il file png veniva rinominato in exe e avviato. Durante l'esecuzione, veniva creato e aggiunto un file VBScript all'avvio automatico. Il VBScript malevolo analizzava ciclicamente il contenuto degli appunti per verificare la presenza di informazioni simili a indirizzi di portafogli crittografici e, in caso di individuazione, sostituiva il numero del portafoglio, contando sul fatto che l'utente non si accorgesse delle differenze e trasferisse fondi non sul portafoglio giusto. <\/p>\n<p>Lo studio condotto ha dimostrato che non \u00e8 difficile riuscire a far aggiungere pacchetti malevoli in uno dei repository pi\u00f9 popolari e che questi pacchetti possono rimanere inosservati, nonostante il considerevole numero di download. Va notato che il problema <noindex><a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=50462\">non<\/a><\/noindex> <noindex><a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=51056\">\u00e8 specifico<\/a><\/noindex> <noindex><a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=51321\">per<\/a><\/noindex> di RubyGems e riguarda altri repository popolari.

Prima di questo, un backdoor era stato <noindex><a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=49665\">scoperto<\/a><\/noindex> nella dipendenza del pacchetto NPM event-stream e il codice malevolo era stato scaricato circa 8 milioni di volte.
