Paris: The trial of a Russian man alleged to have used ransomware in a 135 million euros ($157 million) bitcoin fraud will begin Monday.
French prosecutors say Alexander Vinnik was one of the creators of malware called "Locky" which was delivered through email. If downloaded, the recipient's data was encrypted and they were asked to pay a ransom in bitcoin to free it.

In France, companies, legal offices and local councils were targeted between 2016 and 2018. Twenty victims paid the ransom through BTC-e, one of the world's largest digital currency exchanges.
Vinnik, 41, says he was a only technical consultant at BTC-e and had no knowledge of the illegal activity. He has denied any wrongdoing.
