Lurking in the shadiest corners of the dark web is a “well-established” ecosystem of hackers that target cryptocurrency users with poor “security hygiene,” according to Binance’s chief security officer.
Speaking to Cointelegraph, Binance CSO Jimmy Su said in recent years, hackers have shifted their gaze toward crypto end-users.

In April, a research paper by Privacy Affairs revealed cybercriminals have been selling hacked crypto accounts for as little as $30 a pop. Forged documentation, often used by hackers to open accounts on crypto trading sites can also be bought on the dark web.
Data refiners
According to Su, the data gathered is then sold downstream to another group — usually made up of data engineers that specialize in refining…
