Just this morning, a deadly new strain of ransomware called Petya has been spotted in the wild — and is growing rapidly. According to ABC News, there have been reports of Petya striking government systems and telecommunications providers throughout Europe. There are also unconfirmed reports that systems in North America may be impacted as well.
