The infrastructure was compromised using a php zero-day vulnerability that allowed the hacker to gain access to the full database of sites and delete all the accounts inside. If you browse the deep web — even if it’s just to check out your dental bill — it’s a good idea to equip your device with trusted security software and keep it up to date.
A prominent example is a site called daniel’s hosting, which used to provide tor hosting services to about 6,500 onion websites. Unlike the deep web, which contains important and useful information, the dark web is riddled with illegal and unconscionable activity. A rule of thumb: if you have to log in to one of your accounts by providing a user name, password, or some other type of authentication, the information you access is on the deep web.
A similar ratio (about 15%) holds for the surface web this number, which provides an estimate for the size of the tor network, complements the findings of an onionscan report from 2017, which reported a live rate of 4,400 live sites out of 30,000 others also claim that the network is shrinking while we cannot directly compare against their numbers because their approach was not as broad as our spider, we do find that the ratio of live to dead continues to be similar to these previous findings, with about 15% of the sites being live.
On the other side of the coin, insikt group’s research has shown that much criminal activity happens on sites not requiring any special protocols to access, such as public social media sites like twitter or messaging services like whatsapp and telegram. Instead, you would have to go to the public library’s website and use a search bar inside the website to locate this data on the library’s servers.
