Un gruppo di ricercatori dell'Universit\u00e0 Ca' Foscari (Italia) ha analizzato 90.000 host correlati a 10.000 dei pi\u00f9 grandi siti web classificati da Alexa, giungendo alla conclusione che il 5,5% di essi presenta gravi problemi di sicurezza nelle implementazioni di TLS. Durante lo studio sono state esaminate le problematiche legate all'uso di metodi di crittografia vulnerabili: 4.818 degli host problematici risultavano soggetti ad attacchi MITM, 733 presentavano vulnerabilit\u00e0 che consentivano di decrittografare completamente il traffico, e 912 permettevano la decrittografia parziale (ad esempio, l'estrazione di cookie di sessione).<\/p>\n

Sono state identificate gravi vulnerabilit\u00e0 su 898 siti che consentivano di comprometterli completamente, ad esempio tramite l'inserimento di script nelle pagine. 660 (73,5%) di questi siti utilizzavano script esterni caricati da host vulnerabili, dimostrando la rilevanza degli attacchi indiretti e la possibilit\u00e0 della loro diffusione a cascata (un esempio \u00e8 l'hacking del contatore StatCounter, che potrebbe aver portato alla compromissione di oltre due milioni di altri siti).<\/p>\n

Il 10% di tutti i moduli di accesso sui siti esaminati presentava problemi di privacy, che potrebbero potenzialmente portare a furto di password. 412 siti avevano problemi con l'intercettazione dei cookie di sessione. 543 siti avevano problemi con il controllo dell'integrit\u00e0 dei cookie di sessione. Oltre il 20% dei cookie esaminati era vulnerabile a perdite di informazioni a soggetti che controllano i sottodomini.
