Webbl\u00e4saren Brave har uppt\u00e4ckt en l\u00e4cka via DNS av data om onion-sajter som \u00f6ppnas i privat surfl\u00e4ge, d\u00e4r trafiken dirigeras genom Tor-n\u00e4tverket. Problemfixarna har redan implementerats i Brave:s kodbas och kommer snart ing\u00e5 i n\u00e4sta stabila uppdatering. <\/p>\n

Anledningen till l\u00e4ckan var en annonsblockerare som f\u00f6reslogs att st\u00e4nga av n\u00e4r man anv\u00e4nder Tor. P\u00e5 senare tid har annonsn\u00e4tverk b\u00f6rjat anv\u00e4nda inhemska subdom\u00e4ner f\u00f6r att kringg\u00e5 annonsblockerare, vilket \u00e5stadkommer att en CNAME-post skapas p\u00e5 den server som hanterar sajten, vilket pekar p\u00e5 v\u00e4rden f\u00f6r annonsn\u00e4tverket. P\u00e5 s\u00e5 s\u00e4tt laddas annonskoden formellt fr\u00e5n samma prim\u00e4ra dom\u00e4n<\/a>, som sajten, och blockeras d\u00e4rf\u00f6r inte. F\u00f6r att uppt\u00e4cka s\u00e5dana manipulationer och identifiera v\u00e4rden kopplade via CNAME, utf\u00f6r annonsblockerare ytterligare namnuppl\u00f6sning i DNS. <\/p>\n

I Brave passerade vanliga DNS-f\u00f6rfr\u00e5gningar n\u00e4r en sajt \u00f6ppnades i privat l\u00e4ge genom Tor-n\u00e4tverket, men annonsblockeraren utf\u00f6rde CNAME-uppl\u00f6sning via huvud-DNS-servern, vilket ledde till en l\u00e4cka av information om de \u00f6ppnade onion-sajterna till DNS-servern fr\u00e5n leverant\u00f6ren. Det \u00e4r v\u00e4rt att notera att Brave:s privatl\u00e4ge baserat p\u00e5 Tor inte marknadsf\u00f6rs som garanterande anonymitet, och anv\u00e4ndare varnas i dokumentationen om att det inte ers\u00e4tter Tor Browser, utan endast anv\u00e4nder Tor som en proxy.
