Ransomware: The latest chapter

Ransomware: The latest chapter

  • Written by Daniel Clayton / Dark Reading
  • 22nd September 2022

Ransomware is the most significant cybersecurity threat facing organizations today. But recently, leaders from the National Security Agency and the FBI both indicated that attacks declined during the first half of 2022. The combination of sanctions on Russia, where many cybercriminal gangs originate, and crashing cryptocurrency markets may have had an effect, making it difficult for ransomware gangs to extract funds and get their payouts.

But we aren’t out of the woods yet. Despite a temporary dip, ransomware is not only thriving but also evolving. Today, ransomware-as-a-service (RaaS) has evolved from a commoditized, automated model relying on prepackaged exploit kits, to a human-operated, highly targeted, and sophisticated business operation. That’s reason for businesses of any size to be concerned.

Becoming RaaS

It is widely known that today’s cybercriminals are well equipped, highly motivated, and very effective. They didn’t get that way by accident, and they haven’t remained so effective without continuously evolving their technologies and methodologies. The motivation of massive financial gain has been the only constant.

Early ransomware attacks were simple, technology-driven attacks. The attacks drove increased focus on backup and restore capabilities, which led adversaries to seek out online backups and encrypt those, too, during an attack. Attacker success led to larger ransoms, and the larger ransom demands made it less likely that the victim would pay, and more likely that law enforcement would get involved. Ransomware gangs responded with extortion. They transitioned to not only encrypting data, but exfiltration and threatening to make public the often-sensitive data of the victim’s customers or partners, introducing a more complex risk of brand and reputational damage. Today, it isn’t unusual for ransomware attackers to seek out a victim’s cyber-insurance policy to help set the ransom demand and make the whole process (including payment) as efficient as possible.

We have also seen less disciplined (but equally damaging) ransomware attacks. For example, choosing to pay a ransom in turn also identifies a victim as a reliable fit for a future attack, increasing the likelihood it will be hit again, by the same or a different ransomware gang. Research estimates between 50% to 80% (PDF) of organizations that paid a ransom suffered a repeat attack.

As ransomware attacks have evolved, so have security technologies, especially in areas of threat identification and blocking. Anti-phishing, spam filters, antivirus, and malware-detection technologies have all been fine-tuned to address modern threats to minimize the threat of a compromise through email, malicious websites, or other popular attack vectors.
