A new ransomware called Petya hit multiple high profile companies across the United States and Europe on Tuesday. Here are 3 things to know.
- At the moment, Petya has not permeated as many machines as ransomware WannaCry did in May but it is more dangerous. According to experts, WannaCry was dangerous but it had poor implementation whereas Petya appears to me a much more vigorous attack. Further, Petya is proving to be more difficult to stop according to security experts.
- Another similarity between the two ransomware attacks is that they are praying on vulnerable older Windows systems called EternalBlue. To protect yourself from these attacks, we strongly encourage you to download patches provided by Microsoft. If you have automatic updates enabled on your computer, you should have the patch. If you are unsure about how to tweak this setting, here is a good article explaining how to do so.
- At this point, it’s not totally clear how computers became infected with the ransomware but it does not seem to be through email (which was the case with WannaCry). Images of machines affected were posted on social media circuits showed a message stating “Your files are no longer accessible because they have been encrypted,” while demanding a $300 ransom via Bitcoin digital currency.
