The first month of 2026 has been anything but quiet in the cybersecurity world. If you’ve been heads-down on projects and haven’t had time to catch up on the threat landscape.
Let me walk you through what’s been happening from late December 2025 through January 2026.
AI Is Now a Double-Edged Sword
This probably won’t surprise anyone who’s been paying attention, but AI has firmly made itself as the defining theme of modern cybersecurity. The twist? It’s simultaneously our greatest ally and our most formidable adversary.
Attackers Are Getting Creative with Generative AI
The bad guys aren’t just experimenting with AI anymore. They’re operationalizing it. We’re seeing generative AI power increasingly sophisticated phishing campaigns that are genuinely difficult to distinguish from legitimate communications. Gone are the days when you could spot a phishing email by its broken English or weird formatting.
Deepfakes have crossed from “concerning” to “catastrophic.” Remember the Arup case? Attackers used AI-generated video to impersonate executives and walked away with $25 million. That’s not a theoretical risk anymore. That’s real money walking out the door because someone trusted what they saw on a video call.
Ransomware has evolved too. Variants like LunaLock and PromptLock are using AI for smarter victim targeting. Think about that for a second. The malware itself is getting better at deciding who to hit and how to maximize damage.
Defending AI Systems Is the New Frontier
Here’s something I’ve been watching closely: the explosion of AI agents in enterprise environments is creating attack surfaces we haven’t fully mapped yet. These autonomous systems make decisions and take actions, which means they need runtime security that can keep pace with their operations.
If your organization is deploying AI agents, and let’s be honest, most are or soon will be, you need to think about:
- Real-time monitoring of agent behavior
- Posture management specific to AI workloads
- Governance frameworks with actual teeth
The conversation has shifted from “how do we prevent everything” to “how do we build resilience.” Prevention is still important, but the assumption now is that something will get through. Your architecture needs to account for that reality.
Ransomware Isn’t Going Anywhere
If you were hoping ransomware would fade into the background, I have disappointing news. The economics still work too well for attackers.
The numbers are staggering. Cybercrime costs are projected to hit $12.2 trillion annually by 2031. That’s up from $10.5 trillion in 2025. Ransomware remains one of the primary drivers.
What’s changed is the infrastructure. Groups are now using blockchain-enhanced command-and-control systems, which makes detection significantly harder. Traditional network monitoring approaches struggle when the C2 traffic blends in with legitimate blockchain activity.
We’ve seen active campaigns from groups like Dire Wolf targeting energy and oil sectors. Perdana Petroleum was one notable victim. Critical infrastructure remains in the crosshairs, which brings me to my next point.
Geopolitics and Critical Infrastructure
The threat landscape doesn’t exist in a vacuum. Geopolitical tensions are directly translating into cyber operations.
A few developments worth noting:
There was a failed but significant cyberattack on the Polish power grid in late 2025, attributed to Russia-linked actors. The keyword there is “failed,” but the attempt itself signals ongoing intent. Since the Ukraine conflict began, European critical infrastructure has been under sustained pressure.
CISA has been vocal about China’s cyber ambitions. They’re calling it one of the top challenges facing US organizations. This isn’t speculation or fear-mongering. It’s based on observed activity and intelligence assessments.
Closer to home, there are elevated threat warnings for US critical infrastructure following Operation Absolute Resolve in Venezuela. If you’re in any sector touching critical infrastructure, your threat model should reflect this geopolitical reality.
Identity Remains the Perimeter
Here’s something I’ve seen repeatedly in incident response engagements: identity is where attacks start, and it’s where they succeed or fail.
The AiTM Problem
Adversary-in-the-Middle phishing combined with Business Email Compromise is having a moment. These aren’t your grandfather’s phishing attacks. They’re multi-stage operations that abuse legitimate platforms like SharePoint to appear trustworthy.
The attack chain typically looks like this:
- Initial phishing email that looks legitimate
- Redirect through trusted services to capture credentials
- Session hijacking that bypasses MFA
- BEC fraud using the compromised account
The platform abuse is particularly frustrating. When the phishing link points to SharePoint, your users have been trained to trust it. That trust is being weaponized.
Spoofing Is Getting Sophisticated
Email authentication misconfigurations are being exploited for spoofing at scale. Complex routing setups create gaps that attackers know how to find. If you haven’t audited your DMARC, DKIM, and SPF configurations recently, put that on your list.
Identity Threat Detection and Response (ITDR) has become a core strategy for 2026. Between phishing, leaked credentials, and social engineering, protecting identities isn’t optional anymore. It’s foundational.
Vulnerabilities
CISA’s Known Exploited Vulnerabilities catalog has been busy this month. We’ve seen at least 10 new additions across multiple batches, all actively exploited in the wild.
The Highlights
- Microsoft’s January Patch Tuesday addressed 114 vulnerabilities, including three zero-days. One of those zero-days was actively exploited before the patch dropped. If your patching cadence is monthly, you were exposed.
- Cisco had a rough patch with an exploited RCE in Unified Communications Manager (CVE-2026-20045). Given how widely deployed UCM is, the potential impact is massive.
- Fortinet is dealing with a critical FortiSIEM flaw under active exploitation. If you’re running FortiSIEM, check your version immediately.
- React Server Components had a pre-authentication RCE vulnerability (CVE-2025-55182) that deserves attention if you’re running that stack.
Pwn2Own Automotive 2026
On a slightly different note, researchers at Pwn2Own Automotive earned over $1 million for discovering 76 zero-days in automotive systems. On one hand, that’s a lot of vulnerabilities. On the other hand, better found by researchers than by attackers. The automotive sector has significant work ahead securing connected vehicles.
What Should You Be Doing?
Based on everything happening right now, here’s where I’d focus energy:
- Revisit your AI security posture. If you’re deploying AI systems, especially autonomous agents, make sure you have appropriate controls and monitoring in place. Governance isn’t just a compliance checkbox anymore.
- Prioritize identity. Implement or enhance ITDR capabilities. Review your MFA strategy and consider phishing-resistant options. Audit your email authentication configurations.
- Accelerate patching. The CISA KEV catalog isn’t just a list. It’s a prioritization tool. If something’s on that list, it’s being exploited now. Not theoretically. Now.
- Plan for resilience. Prevention is necessary but insufficient. Your architecture should assume breach and focus on limiting blast radius and enabling rapid recovery.
- Watch the geopolitical landscape. If your organization touches critical infrastructure or operates in sensitive sectors, factor geopolitical developments into your threat modeling.
Looking Ahead
January 2026 hasn’t produced a single headline-grabbing mega-breach, but the steady drumbeat of vulnerabilities, exploits, and evolving tactics should keep security teams plenty busy. The acceleration of AI-augmented attacks is real, and defenders need to match that pace.
The organizations that will fare best are those treating security as a continuous discipline rather than a series of one-time projects. Zero Trust architectures, integrated security platforms, and identity-centric approaches aren’t buzzwords. They’re practical responses to the threat environment we’re actually facing.
