There Are Only So Many Ways to Cook an Egg. Same for Encryption.

Quell fights ransomware at the final step of an attack, when files are being encrypted. There are more ways to breach a network than to encrypt files. Every file write goes through the operating system's file system driver, a chokepoint with a limited set of commands. Ransomware can vary its approach, but it can only cook the egg so many ways.

What's inside

• The write methods ransomware uses, from direct overwrites to memory-mapped writes
• Common evasion tricks like partial encryption and mixed file operations, and why they're still just omelettes
• Why new and unknown variants look the same to Active Containment®

If Quell can see bytes being written to files, it detects the attack, whatever the variant.
