Hackers have scooped out more than $143,000 worth of Bitcoin which was paid as a ransom of $300 by victims for unlocking the device in a WannaCry attack three months ago that affected more than 300,000 computers from over 150 countries.
The attack locked down the files on the computers of businesses, government organisations and the U.K’s National Health Services. Britain's National Health Services became the soft target owing to the systems still running on the outdated Windows operating system.
The ransom paid by the victims was made in Bitcoin payments totalling 52.2 BTC (approx. $143,000) were withdrawn last night, with the final withdrawal made at 3:25 a.m., and have been exchanged for Monero.
Monero is the choice of currency as it is a highly privacy oriented cryptocurrency, which makes it difficult to track the transactions. The current balance of the associated wallets with the ransomware attack is nil.
The WannaCry funds were transferred to a cryptocurrency conversion platform, ShapeShift.io. It doesn’t require any registration and hence maintains complete anonymity
