Reasons for an upward shift in the percentage of Ransomware attacks

  • Trojan malware has seen 200% increase from the previous quarter and almost 650 % from the same time last year.

  • ‘Emotet’ trojan is still targeting enterprises. Detection of Trojans for businesses has increased by more than 200% since the last quarter of 2018 which is almost 650% more in comparison with the same time last year.
  • U.S. leads with the maximum number of global threat detection at 47%, followed by Indonesia with 9% and Brazil with 8%.

What should be done to curb this increasing percentage of ransomware attack?

  • Train employees with regular cyber security awareness and training sessions.
  • Limit employees’ authority to download or install software or data to which they can have an access.
  • Cyber attack simulation and awareness tools like ThreatCop help in strengthening employees’ defenses against any real-life cyber-attack.
