INUKSHUKTM protects user data against most advanced ransomware attacks, without using an online backup system or requiring any new hardware changes, INUKSHUK uses off-the-shelf hardware.

The main challenges in cybersecurity against ransomware attacks:

  • Growing evolution of ransomware, motivated by direct monetization.
  • Current products fail against rootkit ransomware attacks
  • Root-privileged ransomware can defeat user-privileged and root-privileged defenses.
  • New emerging ransomware is always one step ahead.
  • Most of detection-based mechanisms are often too late in protecting user data.

New cybersecurity strategy at the level of primitive material (hardware)

  • InukshukTM is Off with defenses, On with immunization.
  • Hardware-enforced write-protection
  • Even ransomware with highest software privilege cannot modify user data.
  • Use a dynamic root of trust measurement (DRTM) for write protection.
  • User data is only appended, and modification and deletion are versioned, and is immune to ransomware’s encryption.
  • A patent pending technology developed by prof. Mohammad Mannan and Lyaning Zhao at Concordia University.

Trusted write protection demonstrate effective cybersecurity protection advantages

  • Offer user data immunization against all virus and malware, including ransomware.
  • Cost effective
  • Uses commercial off the shelf Self Encrypted Drive (SED).
  • DRTM makes InukshukTM independent of most computer firmware, such as UEFI/BIOS.
  • No access overhead for data in use, only synchronizes in batch at idle time.
  • Can be implemented on common platforms: Windows, Linux, Apple OS…

Business opportunity in Cybersecurity

  • Technology available for licensing.
  • Co-development for specific platform implementation.
