James Smith, CEO of Elliptic, a London-based start-up that helps law enforcement agencies track criminals using the cryptocurrency, said his company had uncovered that since Friday, around $50,000 worth of bitcoin payments have been made to the hackers by 7 a.m. ET on Monday. This was up from $45,000 at 4 a.m. ET.
"We have seen the number of payments start to go up today," Smith told CNBC Monday.
After 72 hours from when the attack started on Friday, the hackers said the fine would double to $600, and after seven days, the files would be permanently locked.
"We think over the course of today as we approach the first deadline where fines double we will see a bigger increase (in bitcoin payments)," Smith added.
The amount paid so far is still a small amount despite the global nature and scale of the attack. Security experts and government agencies have been urging people not to pay the ransom.
