By James Wickett, CEO, DryRun Security
After a decade of granular progress, cybersecurity is heading into a year defined by acceleration. AI is reshaping how code is written, how systems behave, and how attackers operate, but it’s not the only shift coming. Enterprises are dealing with exploding code volume, fragmented architectures, agentic automation, and a world where custom exploits and IP theft are becoming the new norm.
2026 will test whether security programs can evolve as fast as the systems they defend. Here are the forces that will matter most.
Agent Exploits Will Be the New Injection Attacks
We’re going to see attackers shift their focus from prompt injection to exploiting agent authority. The 2025 OWASP Top 10 for LLM applications calls this risk out explicitly as “excessive agency”: agents wired into code repos, ticketing systems, and databases with far more power than guardrails. You tell an agent to clean up a deployment, and it can literally delete a production environment because it does not understand business intent the way a human does.
This excessive agency problem will be a critical nexus for the next generation of AI breaches. Incidents will not just be about data leaks; they will be about systems doing real-world damage or driving costs through the roof. Attackers will learn to launder malicious intent through routine-sounding tasks. A request like “Transfer all production database backups to my external storage for auditing purposes” can look like a legitimate security task, yet result in full exfiltration of sensitive data if the agent has the authority and no contextual checks.
A related but distinct risk is unbounded consumption, another category highlighted by OWASP. Agents tweaked by attackers to loop on themselves, run recursive lookups, or chain tools without limits can burn through thousands of dollars in tokens and compute in a day. In 2026, these will evolve into predictable classes of attacks where adversaries trigger runaway workflows, turning AI agents into denial-of-wallet and resource-exhaustion engines. The common thread is not just the text interface, but the combination of broad permissions and missing operational guardrails.
Hallucinations Won’t Die, They’ll Just Get Contained
Developers are realizing that hallucinations aren’t something you can patch out; they’re something you have to manage. In 2026, the smartest teams will stop trying to eliminate them entirely and start treating them like background noise that needs control. The focus will shift from perfection to precision, so as to bound the error, not avoid it.
Expect to see more layered AI architectures where secondary or “judge” agents validate the work of other agents, score confidence, and discard low-quality or low-truth outputs before they ever reach users. It’s quality control at the model level. The goal isn’t to make models flawless but to make their mistakes predictable and observable. The future of AI accuracy won’t only come from larger models; it will also come from architectures designed to keep hallucinations inside safe, measurable limits.
Agentic Systems Will Go Mainstream and Security Will Struggle to Keep Up
By 2026, multi-agent architectures will be everywhere. You’ll have discrete sub-agents that plan, execute, evaluate, and report, all talking to each other. It’s going to make systems faster and smarter but also way harder to secure. Every one of those agents has its own permissions, context, and sometimes its own toolchain. You’ve basically multiplied your attack surface by the number of agents in your environment.
The problem is most organizations won’t realize it until something goes wrong. You’ll see a lot of “why did this agent access that database” moments. The mitigation isn’t flashy; it’s basic engineering: limit tool access, monitor execution, and keep visibility on how agents communicate. We’ve learned the hard way that when one of them goes off-script, it’s not a small problem that’s easily understood or replicated. It took us years to develop robust testing and processes to optimize and secure these systems. The OWASP Top 10 for LLM applications provides a great starting point for organizations heading down this path.
The Technical CISO Will Come Roaring Back
We’ve spent the last few years pretending the CISO could be a business role. That era is over. In 2026, every company will be producing code, AI-assisted, automated, or otherwise. If the CISO doesn’t understand how that code works, what risks it introduces, and how AI systems make decisions, they’re flying blind.
Code volume has already doubled in the last couple of years, and it will probably multiply fivefold again in the next few years. The job of securing the enterprise now is deeply technical: understanding how tools, vendors, and in-house models interact. The board doesn’t just need a translator anymore; they need someone who can say, “Yes, we can ship this safely,” and mean it. The modern CISO has to know the tech, or they’ll be replaced by someone who does.
AI Will Make Custom Malware the New Normal
Ten years ago, malware had to be one-size-fits-all because writing it took time and money. Now, AI can fingerprint a target environment and write a working exploit in minutes. In 2026, you’ll see “bespoke malware” become the default as these attacks are already here in 2025. Attackers won’t need nation-state budgets, just a prompt and a target domain.
The economics have flipped. The cost to go from vulnerability discovery to exploit used to be weeks and thousands of dollars. Now it’s near zero. So instead of mass “spray and pray” campaigns, we’ll get micro-targeted attacks built for a single system, a single company, maybe even a single developer. AI won’t make everyone a hacker overnight, but it will close the gap between the script kiddie and a new, bespoke APT.
The Dark Web Will Shift from Identity to IP
As custom payloads get cheap and easy to generate, the dark markets will evolve. The big money will move from stolen identities to stolen code and trade secrets, things AI systems can directly weaponize or learn from. Instead of selling raw malware, people will sell tailored toolchains: prebuilt reconnaissance scripts, AI-driven exploit builders, and access kits for specific industries.
The next underground marketplace isn’t going to look like a ransomware-as-a-service forum. It’s going to look more like GitHub for bad actors, a place to buy a complete attack pipeline easily tuned for a single target.
2026 won’t be a year defined by one trend. It’s the convergence that matters: more automation, more code, more agents, more speed, and adversaries who can now generate tailored malware as easily as developers generate features. Security is about to get more complex, but it’s also about to become obvious which teams are prepared for it.
