How Stellar Helps to Recover Files Infected By WannaCry Ransomware Attack?

On May 12, 2017, there was an outbreak of a Ransomware called WannaCry that attacked and affected approximately 200,000 Windows computers and 10,000 companies spread in 150 countries across the globe. Therefore, it is considered to be the worst ransomware attack till date.

The WannaCry ransomware targets laptops and desktops and encrypts all data on the hard drive preventing access to it. Further, it spreads laterally among all computers connected to the LAN network by using a susceptibility in the execution of Server Message Block (SMB) present in Windows OS. The WannaCry ransomware also spreads through malicious links or attachments in emails, messages containing malware, infected software, infected external storage media, and infects your system.
