The New Bitdefender RANSOMWARE PROTECTION for WINDOWS & ANDROID is Here!
Ransomware Protection for Windows
Our goal is to detect ransomware attacks proactively, the same way we detect other types of attacks. We are able to pinpoint any suspicious patterns of activity and use our cloud technology to accurately detect a ransomware attack. Users will be notified through a product notification that ransomware was blocked on their device.
Whenever any suspicious pattern of activity emerges on an endpoint, samples are sent to Bitdefender cloud. The sample is automatically analyzed in the cloud and if it’s found to be ransomware, a signature is generated and pushed in less than 30 minutes.
After the signatures gets pushed, propagation takes approximately 3 hours to get on all endpoints via product update.
To minimize the propagation windows, a similarity hash will be calculated for locally executed files and compared to the cloud. If there’s a match with a sample that’s already been tagged as ransomware, but has not yet been delivered to endpoints via update (if it’s still in the 3-hour timeframe), it will automatically be blocked from executing. This will offer the best minimum reaction time.
We also have a dedicated anti-ransomware team that manually analyzes samples. The difference between them and Bitdefender cloud is that while automatic analysis works well on generating signatures for individual samples, the team can actually create a more generic signature, which is more efficient as it can catch unknown samples as well.
Ransomware protection for Android
Important files are not kept only on laptops or used only in secure locations. Ransomware targets Android phones just as easy as malware does, and blocks you from accessing your device altogether. To prevent that, we’re monitoring all suspicious patterns that these types of attack use to lock you out of your phone and use our cloud detection technologies to block them.

Ransomware is good business not only for tech savvies due to:
1. Ransomware-as-a-service platforms
2. Easy and untraceable payments
Although Windows was the system of choice in the past, such attacks have diversified and expanded to Android and Mac as well. Considering the fact that the Android market share is more than 80% worldwide and has more than 1.4 billion 30-day active users globally, this evolution is not surprising.
