Since Friday, more than three lakh computers in over 150 countries, including India, have been in the grips of WannaCry, a ransomware that encrypts all data on a system and demands payment in return for freeing up access.
However, for a cyber attack that is being termed as the largest of its kind in history, WannaCry has failed to raise the amount of money that one would imagine. Hackers behind the global WannaCry ransomware attack, that has hit 150 countries since Friday, have earned about ₹55 lakh so far. Elliptic Enterprises, a London-based company that tracks illicit use of Bitcoin, tracked the current balance of the three Bitcoin addresses known to be associated with WannaCry.
WannaCry, which uses a Microsoft Windows exploit first developed by the United States National Security Agency, works by encrypting and blocking access to all data on an infected computer system. The malware then displays a message telling users not to worry and that their data can safely be restored.
WannaCry demands that users pay between $300 (around Rs 19,000) and $600 (around Rs 39,000) in bitcoin in lieu of getting their data decrypted.
