Any type of crime with covert transactions, whether it involves drugs, money, or even human beings, can be committed on the Dark Web. The darkest corners of the internet are merely a platform for myriad offenses, but here are some examples of Dark Web crimes:
Murder for Hire- The site Besa Mafia (and others like it) is a marketplace for contract killings.
Blackmail/Extortion - One scam involves threats of releasing compromising photos of affairs (even when no such photos exist) unless the victims pay a stated amount of bitcoin.
Illegal Drug Sales - Silk Road is the most highly publicized example, but there are others.
Illegal Arms Sales - Tens of thousands of dollars' worth of guns are illegally sold each month on the Dark Web, according to estimates.
Sex Trafficking - the New York County D.A.'s Office used an experimental internet search tool to catch and prosecute the leader of a sex trafficking ring.
Terrorism - ISIS and other terrorist groups use the Dark Web both for recruitment and planning attacks.
Child Pornography - An estimated 144,000 individuals in Britain alone were using the Dark Web to access child pornography in 2018.
