Things we have learned about Petna, the Petya-based malware

Earlier this week, we saw another mass ransomware attack happen, less than two months after the WannaCry outbreak. In the hours and days after the attack, this strain was given many different names, including Petya, Petna, NotPetya, EternalPetya, Nyetya, and many more. We originally referred to it as Petya-based, but for simplicity, let’s call it Petna.

WannaCry Update – The Worst Ransomware Outbreak in History

While last Friday wasn’t Friday the 13th, it sure seemed like it. PCs around the world, including those belonging to hospitals and government agencies, were hit by the WannaCry (AKA WanaCrypt0r, or WCry) ransomware, causing chaos. Up until now we have seen more than 250,000 detections in 116 countries.
