Where an undercover or informant operation is impractical or impossible, measures to directly infiltrate the computer system may be possible. Undercover operations in which an investigator or informant infiltrates a criminal network (online or in real life) may be able to obtain access to encrypted channels of communication and be part of the evidence in e-mails, chats, and forums located on hidden services on the Dark Web. In cases where monitoring communications is impossible due to anonymous Internet access methods such as the Tor browser or virtual private networks, other means have to be considered. Unfortunately, that’s the tradeoff for anonymity.īrett Shavers, John Bair, in Hiding Behind the Keyboard, 2016 When All Else Fails or Is Likely to Fail Because any requests you make go through a network of servers before reaching its destination, you’ll notice that it’s slower than other browsers you may have used.
