En gruppe forskere fra Ca' Foscari Universitetet (Italien) har analyseret 90.000 hoste relateret til 10.000 af de st\u00f8rste websteder if\u00f8lge Alexa-ster. De konkluderede, at 5,5 % af dem har alvorlige sikkerhedsproblemer i deres anvendelse af TLS-implementeringer. I l\u00f8bet af unders\u00f8gelsen blev der set p\u00e5 problemer med brugen af s\u00e5rbare krypteringsmetoder: 4.818 af de problematiske hoste var udsat for MITM-angreb, 733 havde s\u00e5rbarheder, der tillod fuld dekryptering af trafikken, og 912 tillod delvis dekryptering (for eksempel at udtr\u00e6kke sessioncookies).<\/p>\n

Alvorlige s\u00e5rbarheder, der kan kompromittere 898 hjemmesider helt, blev identificeret, for eksempel via indspr\u00f8jtning af scripts p\u00e5 siderne. 660 (73,5%) af disse hjemmesider brugte eksterne scripts, der blev indl\u00e6st fra s\u00e5rbare tredjeparts v\u00e6rter, hvilket demonstrerer relevansen af indirekte angreb og muligheden for deres kaskadeudbredelse (et eksempel er hackingen af StatCounter, der kunne have kompromitteret mere end to millioner andre hjemmesider).<\/p>\n

10% af alle loginformularer p\u00e5 de unders\u00f8gte hjemmesider havde problemer med fortrolighed, som potentielt kunne f\u00f8re til stj\u00e5lne adgangskoder. 412 hjemmesider havde problemer med at opfange session cookies. 543 hjemmesider havde problemer med kontrol af integriteten af session cookies. Mere end 20% af de unders\u00f8gte cookies var s\u00e5rbare over for l\u00e6kage af information til personer, der kontrollerer underdom\u00e6ner.
