The recent “WannaCry” ransomware outbreak in May infected over 230,000 computers in 150 countries. It was spread by exploiting a known Windows vulnerability. It then encrypted all PC files and requested ransom in Bitcoin to unlock all files.
Exosphere’s defense in depth is able to defeat such an attack:
- PC Healthcheck
When PC Healtheck is in place, the operating system is regularly patched, thereby WannaCry and other ransomware attempting to exploit known vulnerabilities will fail to spread.
Advanced anti-malware will neutralize the threat as soon as it is discovered in the wild.
Exosphere’s anti-ransomware capability implements a data firewall that denies WannaCry (or any other unknown application) from overwriting user data.
Even if all else has failed and the ransomware was able to corrupt user files, these will easy to restore from the Exosphere backup.
