As AI cybersecurity threats accelerate in 2026, Portland businesses need to strengthen their cybersecurity now. The same AI tools we use normally are now being weaponized for AI-powered cyberattacks. Business owners have been looking for tools to boost company productivity; cybercriminals are doing the same. Traditional cyberattacks are happening faster, more frequently, and with less technical skill required.
What’s good about this? AI is also advancing defense systems, and SpireTech leverages these tools to better protect businesses. Here’s what you need to know about AI’s impact on cybersecurity in 2026.
AI Didn’t Create New Attacks—It Made Them Faster
In 2025, cybersecurity experts found that AI didn’t create entirely new forms of cyberattacks. Instead, it accelerated existing tactics. The techniques remain the same, but AI gives threat actors a significant speed advantage.
Something that used to take skilled hackers hours now takes minutes with AI assistance. That is catastrophic without proper protection. Credential theft, ransomware deployment, and social engineering campaigns are automated and executed rapidly by people who don’t need to be experts. For businesses, this means the window between vulnerability and exploitation has just gotten smaller. Are your defenses able to keep up?
Five AI-Powered Threats Targeting Businesses in 2026
Business owners need to understand these five AI-powered cybersecurity threats that will become more popular in 2026. These are revolved attack vectors that combine AI speed with traditional hacking methods.
1. Hyper-Personalized Phishing and Social Engineering
AI has the power to change phishing from generic scam emails into sophisticated and personalized attacks. These systems analyze LinkedIn profiles, company websites, social media, and whatever available data there is on a person to create highly targeted messages that mimic writing styles and reference specific details. Spear phishing just got easier and scarier.
Over 80% of phishing emails now use AI in some way. Business email compromise (BEC) attacks have increased 156% since 2023. AI makes these attacks scalable—what used to target one organization can now target hundreds simultaneously.
2. Automated Ransomware Operations
AI enables attackers to scan networks, identify valuable data, and deploy ransomware with minimal human action. Security experts predict ransomware in 2026 will focus less on encryption and more on intelligent data exploitation, which means more threats of your sensitive information being exposed.
3. Living-Off-the-Land Attacks
Attackers use legitimate system tools like PowerShell, remote desktop protocols, and built-in utilities to conduct malicious activities. These attacks are difficult to distinguish from normal IT operations because they use authorized tools.
AI accelerates the use and chaining of these tools for malicious purposes. Traditional antivirus is essentially useless against these attacks and should not be counted on. Detection requires behavioral monitoring that identifies unusual patterns, like PowerShell being used at 3 AM by a marketing employee’s account.
4. Agentic AI—Autonomous Threats
The Center for Internet Security predicts 2026 will see “fully automated phishing, lateral movement, and exploit-chain engines that require little or no human operator engagement.”
Once they’re inside your network, these AI agents autonomously navigate between systems, escalate privileges, and extract information, without a human doing a thing. Unlike human attackers who need sleep, these systems run around the clock, learning and adapting in real-time.
5. Identity-Based Attacks
More than half of confirmed security incidents in early 2025 were identity-related. This includes session hijacking, credential theft, and unauthorized OAuth applications. AI can automate credential stuffing attacks and predict likely password variations based on leaked data.
Multi-factor authentication provides protection, but attackers are developing increasingly sophisticated techniques to get around this. Modern identity protection requires continuous monitoring of login behavior and access patterns. Verification at login isn’t enough anymore.
Why AI-Only Cybersecurity Fails: The Need for Human Experts
Sophos predicts that “human-in-the-loop security will define 2026.” AI-powered security tools excel at speed and scale, but they’re not infallible. They can misclassify legitimate activities as threats or miss sophisticated attacks that don’t fit expected patterns.
The challenge is alert fatigue. When security systems generate thousands of alerts, someone with average knowledge of IT could become desensitized and start auto-approving actions without taking the time to properly review them. Experienced security professionals provide the context, judgment, and strategic thinking that AI cannot replicate.
SpireTech’s Human-First Approach
At SpireTech, we’ve built our cybersecurity services with a human-first philosophy. We deploy advanced AI-powered tools from industry leaders like Sophos and Huntress—platforms we trust and depend on—paired with experienced professionals who understand your business.
We don’t just monitor your systems, we are an extension of your team that is dedicated to continuously improving our knowledge for your protection and benefit.
How Cybersecurity Services Are Fighting Back
Luckily, modern cybersecurity leverages AI while maintaining critical human oversight. Some common tactics include:
- AI-Powered Behavioral Analytics: Systems analyze behavior patterns to detect zero-day exploits by identifying suspicious activities like unusual file access, data transfers at odd times, or privilege escalations that don’t align with job functions.
- Managed Detection and Response (MDR): Endpoint detection is combined with 24/7 human oversight. Huntress’s average response time is eight minutes—dramatically less than the industry average of 27 minutes. This can be the difference between a minor incident and a major breach.
- Identity Threat Detection and Response (ITDR): With more attacks than ever being identity-based, protecting credentials is paramount. SpireTech uses Huntress’s Managed ITDR as part of our Identity Protection Bundle. This monitors login patterns, detects session hijacking, and identifies suspicious OAuth applications.
What Portland Businesses Should Do Now
If you’re not a client of SpireTech’s and are covering your own cybersecurity, you need to make sure you’re following these security practices as soon as possible.
Essential Security Measures
- Use Multi-Factor Authentication (MFA) everywhere
- Implement endpoint detection and response (EDR)
- Train employees on modern phishing tactics and proper password security/hygiene
- Monitor for unusual access patterns
- Maintain current system patches
- Adopt zero-trust principles
Key Takeaways
Based on predictions from trusted cybersecurity experts, business owners can expect:
- More automated, templated attacks as AI makes hacking easier than ever
- Increased deepfake fraud, especially executive impersonation
- AI governance becoming a compliance requirement
- Greater executive accountability for AI-related incidents
- Attacks targeting infrastructure and hypervisor layers
Organizations that combine AI-powered tools with skilled human oversight will have the advantage in 2026. The key is to focus on proactive preparation. Implement robust security now rather than responding to an incident after it’s happened.
Incidents like the Oregon DEQ ransomware attack and the MOVEit breach affecting ODOT and Oregon Medicaid show that even government agencies are vulnerable. No business should assume they’re too small to be targeted.

FAQs
Q: Has AI made cyberattacks more dangerous?
A: AI has made attacks faster, more accessible, and more frequent, but not fundamentally different. The same security fundamentals like MFA, regular patching, employee training, and continuous monitoring remain effective but need to be implemented more thoroughly with faster response times.
Q: Can traditional antivirus handle cybersecurity threats that use AI?
A: Traditional antivirus relies on recognizing known threat signatures. AI-powered attacks constantly generate new variations that bypass signature-based detection. Modern protection requires behavioral analysis (EDR/MDR) that identifies suspicious activity patterns.
Q: What should I do if my business experiences a cyberattack?
A: Immediately disconnect affected systems from your network. Do not pay any ransom without expert consultation. Contact your IT team or MSP immediately. If you’re a SpireTech client, contact us immediately so we can take the necessary steps to protect your business.
