Dissecting Today's Ransomware Ecosystem

Ransomware-As-A-Service, Targeted Intrusions and Opportunistic Attacks

For years, ransomware has been a significant threat to organizations. But cybercrime as we know it has changed. What were once opportunistic attacks used to exploit individuals have turned into well-orchestrated attacks aimed at high-value organizations to cripple business operations and wreak chaos.

Even the threat actors behind ransomware attacks are far more sophisticated and savvy than the petty criminals they used to be. Their operations are organized, well-run, and even leverage role specialization to expand the reach and velocity of modern ransomware campaigns.

Since initial access to data exfiltration and deployment of ransomware can unfold in mere hours, CISOs need to re-evaluate their security program, posture, and controls against the backdrop of the heightened risk organizations face from today's threat actors. In addition, Security Operations teams need up-to-date threat detection capabilities and incident response playbooks to fully respond and remediate ransomware threats.

Read this report for insights on modern ransomware threats from eSentire’s Threat Response Unit (TRU) experts, including:

  • The emergence of Ransomware-as-a-Service
  • How criminals use ransomware to perform both opportunistic and targeted attacks against organizations
  • Case studies and observations on the most popular initial ransomware attack access techniques
  • Ransomware deployment techniques and extortion tactics 
  • Actionable takeaways that can be utilized to combat ransomware threats
