Cybercriminals used ransomware to haul in approximately $1bn in 2016, according to a security expert who wished to remain anonymous. Bitcoin wallets associated with the Locky ransomware processed $120m, whilst Cryptowall brought in $100m before it was shut down. It is hard, however to verify these figures because cybercriminals are using increasingly complex methods to hide their tracks. The number of ransomware attacks is set to rise in the upcoming year, although at a slower rate than in prior years.
