Many big companies, power suppliers and governments around the world have been affected by a series of malicious software known as Petya, which locks the infected computer and shows a ransom request on the screen asking for $ 300 through Bitcoin coins to open infected devices, More than 230,000 computers were attacked in more than 150 countries in May.
But the payment system developed by the pirates is largely useless; they used only one address for currency payments, which the e-mail provider actually stopped. Ransom software is believed to be a cover for malicious programs designed to do a lot of damage, especially for the Ukrainian government. Besides making the computer and its data useless, there are also software inside Petya that steal user names and passwords.
Petya software is actually the name of an older version of malware, and when major differences appeared between the two versions the researchers gave the new version the current name GoldenEye.
