This makes it easier for them to find out who has paid and then manually restore that person's encrypted files. It helpfully offers victims translations of its demand for money in 28 different languages, and does not discriminate much in its targets. Now, it's been revealed that the bitcoin "wallet" used to receive WannaCry's ill-gotten digital gains has raised only a bit more than $69,000.
One bitcoin recently traded for $1,734.65, according to Coinbase, a company that helps users exchange bitcoins. Victims who don't pay will have their files erased after seven days. While there are no official figures, researchers say many users and companies have managed to get back their files after paying the ransom.
"It really is knocking on a bunch of doors, if you will", Wice said. Barlow said that single payments in some other ransomware cases were more than that, depending on the victim. Security experts and government agencies have been urging people not to pay the ransom.

The WannaCry malware that spread to more than 100 countries in a few hours is throwing up several surprises for cybersecurity researchers, including how it gained its initial foothold, how it spread so fast and why the hackers are not making much money from it.
Windows computers with Windows Patch MS17-010 are affected by the large-scale ransomware outbreak, which "spreads laterally" and hence its impact is more devastating, according to Redsocks, a malicious threat-detection firm.
