AI ransomware network defense: a new priority as tactics shift

New research from Check Point highlights a shift in how ransomware operators are working, and why the old playbook of backup-and-restore is no longer enough on its own. The data shows something counterintuitive: as backup and recovery technology has improved, attackers haven't given up. They've adapted. Ransom payment rates have fallen for six straight years, from around 85% in 2019 to roughly 23% today, and that decline is reshaping attacker strategy in ways that put more pressure on network-level defenses like segmentation and controlled remote access.

This matters for anyone responsible for protecting business systems, and it matters for the broader conversation around AI ransomware network defense, because the tools that once felt optional (segmentation, VPN-gated access, least-privilege networking) are becoming central rather than supplementary.

How AI is lowering the barrier to entry

Check Point's research points to artificial intelligence as a factor reducing the technical skill needed to run a ransomware operation. Tasks that once required specialized coding knowledge, custom malware development, or deep familiarity with target environments can now be accelerated or automated with AI tools. That doesn't necessarily mean AI is inventing new attack categories overnight, but it does mean more people can participate in ransomware operations with less experience, and existing groups can operate faster and at greater scale.

This lowered barrier connects to a wider pattern already visible in the ransomware landscape. As covered in reporting on how the ransomware ecosystem is fracturing into dozens of active groups, the field isn't consolidating around a few dominant players. Instead, it's splintering into many smaller, more agile operations. AI tooling likely accelerates that fragmentation by making it easier for smaller or newer groups to launch credible attacks without the resources that used to be a barrier.

Why declining payment rates are pushing attackers toward data theft

The drop in ransom payment rates isn't a sign that ransomware is fading. It's a sign that encryption alone has stopped being a reliable moneymaker. When organizations can restore systems from backups without paying, the leverage that encryption once provided evaporates. Attackers have responded by shifting emphasis toward data theft and extortion based on the threat of public exposure, rather than relying solely on locking up files.

This is a meaningful distinction for defenders. A ransomware strategy built around "we have good backups, so we're covered" addresses the encryption half of the threat but does little to stop data from being copied and exfiltrated before encryption even happens. If attackers can move laterally through a network, find sensitive data stores, and quietly extract information, backups become irrelevant to that part of the attack. The extortion threat shifts from "pay us to get your data back" to "pay us or we leak what we already took."

Where backups fall short: the case for segmentation and controlled access

This is where network architecture becomes as important as recovery planning. Backups protect against data loss, but they do nothing to prevent an attacker from browsing a flat network, hopping between systems, and reaching data they were never authorized to touch in the first place. Two controls matter more in this environment:

Network segmentation limits how far an attacker can move once they gain initial access. If a compromised device sits on an isolated segment with restricted pathways to sensitive systems, the blast radius of a breach shrinks dramatically, even if AI-assisted tools helped the attacker get in quickly.

VPN-based and identity-aware access control restricts who and what can reach internal resources at all. Rather than allowing broad network access once someone is inside the perimeter, modern access approaches verify identity and device posture continuously, and route traffic through controlled, encrypted channels. This reduces the chances that a single compromised credential or endpoint becomes a gateway to the entire network.

Together, these controls address the part of the attack chain that backups can't: the reconnaissance and lateral movement phase where data theft actually happens.

What This Means For You

For IT and security teams, the takeaway is straightforward: recovery planning and access control need to be treated as complementary, not interchangeable. Good backups protect against downtime and data loss from encryption, but they don't stop theft, and theft is increasingly the leverage attackers rely on. Reviewing how flat or segmented your network is, and how tightly remote and internal access is controlled, is a practical next step regardless of company size.

For individual users and smaller organizations, the principle scales down too. Limiting what any single device or account can reach, using strong access controls for remote connections, and being skeptical of unusual account activity all reduce the odds that one compromised entry point turns into a full-scale breach.

Actionable takeaways

  • Don't rely on backups alone; they address encryption but not data theft, which is now a primary extortion tactic.
  • Audit network segmentation to limit lateral movement if a device or account is compromised.
  • Strengthen VPN and remote access controls with identity verification rather than broad perimeter trust.
  • Stay informed on how ransomware groups are evolving, since AI tools are enabling more, smaller, and faster-moving operations across a fragmented ecosystem.
  • Treat AI ransomware network defense as an ongoing layered strategy, not a one-time upgrade.

As AI continues to reshape the economics and mechanics of ransomware, the organizations that hold up best will be the ones treating network defense, not just recovery, as their first line of protection.
