The WannaCry name belongs to the ransomware program that was launched this past Friday that has already infected close to 1/4 million Microsoft Windows systems across 150 countries, with an asking price of $300 in bitcoin to decrypt your files… or $600 if you wait too long.
The ransomware spreads to unpatched Windows systems as a computer worm leveraging the SMB protocol and through phishing emails.
It’s believed that WannaCry leverages the NSA’s EternalBlue exploit, which was publicized by the Shadow Brokers.
Keep your systems updated, keep good backups of your data, and be suspicious of emails you get!
