Quote:CiperTrace reports that hackers have stolen $927 million worth of cryptocurrency in the first three quarters of 2018, while around 97 percent of all payments to and from criminals have been made using unregulated cryptocurrency exchanges.

The most notable incidents that lead to large amounts of cryptocurrency being stolen were the breaches of the Coincheck exchange with a whopping $530 million and BitGrail with $195 million. Because of the substantial cryptocurrency heists that occurred in 2018, the volume of stolen cryptocurrency was 3.5 times larger than the one of 2017, with an apparent climbing trend for the last quarter of 2018 which means that cybercriminals will siphon at least $1 billion until the end of the year.
"The study defined ‘criminal sources’ as dark market site, extortion, malware, mixer/tumbler/money laundering site, ransomware, and terrorist financing that CipherTrace has been able to identify and validate as of 9/29/2018," according to the CipherTrace report (.PDF).
