Anthropic’s reported development of Claude Mythos signals a shift: AI is compressing attack timelines by accelerating vulnerability discovery, exploit development, and multi-step attack planning. More broadly, AI is increasing the speed and scale of attacks across malware, phishing, and vulnerabilities.

Attackers can now run these vectors in parallel, reducing time to compromise and increasing exposure.

AI also enables more targeted phishing, faster malware iteration, and rapid vulnerability discovery, exposing gaps in detection and exposure management earlier and requiring prevention-first controls and real-time detection.

To see how these challenges translate into real-world performance, and how leading security vendors handle them under pressure, explore the 2026 Miercom Hybrid Mesh Network Security Competitive Assessment.

Malware: Faster Creation, Smaller Window to Stop It

AI is accelerating how malware is created, modified, and deployed.

Attackers can generate and iterate payloads at scale, automatically adjusting code to evade detection and testing variations against defenses in near real time.

Check Point Research illustrated this shift by identifying the VoidLink framework, one of the first documented examples of sophisticated malware developed largely by AI. The AI-driven framework can generate, modify, and deploy malicious code with built-in evasion, while dynamically adjusting behavior, reusing components, and streamlining deployment. In practice, this reduces manual effort and significantly accelerates the creation and testing of new variants against defenses.

The result is a compressed detection window, especially in the first 24 hours, when new threats lack indicators and can move before defenses update.

Phishing: Scale and Precision at the Same Time

With the introduction of AI, phishing infrastructure has become short-lived and dynamic. URLs, domains, and page content are created and rotated quickly, often disappearing before traditional blocklists update. AI also enables real-time variation, where content and landing pages adjust based on user interaction.

These changes reduce the effectiveness of static filtering and shift detection toward real-time analysis of behavior, content, and intent.

Vulnerabilities: Discovery and Exploitation Are Converging

AI is changing how vulnerabilities are found and used in attacks. Models can scan code and configurations, correlate weaknesses across components, and map viable attack paths with minimal manual effort. This reduces the time from discovery to action and compresses the gap between disclosure and exploitation.

Modern environments spanning cloud, APIs, and on-prem systems create more interconnected components. AI can evaluate these environments at scale, surfacing combinations of weaknesses that would be difficult to identify manually.

The result is a faster path from exposure to compromise, where vulnerabilities are more likely to be chained and used in active attacks.

What This Means for Network Security

AI-driven attacks increase pressure on the network layer, where traffic, access, and application interactions converge.

Initial access often enters through internet-facing services, VPNs, or SaaS applications. From there, activity moves over legitimate channels using encrypted traffic, APIs, and identity systems that traditional controls do not fully inspect.

This shifts the role of network security from perimeter filtering to continuous, inline prevention across users, cloud, and on-prem environments. Effective controls must inspect traffic in real time, detect malicious behavior within legitimate sessions, block exploits targeting exposed services, and maintain consistent enforcement across hybrid environments.

Security effectiveness is defined by how well these capabilities work together under continuous, multi-vector pressure.

What Real-World Testing Shows Under Pressure

Check Point engaged Miercom to evaluate hybrid mesh network security solutions in a controlled, comparative test against Cisco, Fortinet, Palo Alto Networks, and Zscaler. All security services were enabled, focusing on detection and blocking of modern threats.

Testing included early-stage malware prevention, phishing detection for short-lived URLs, protection against actively exploited vulnerabilities, and performance under load.

Key Findings

• Industry leading threat prevention: Check Point achieved the highest overall security effectiveness in the Miercom evaluation, scoring 99.8% and leading across all categories tested against Palo Alto Networks, Fortinet, Cisco, and Zscaler.
• Immediate protection against emerging malware: Check Point prevented 99.9% of new malware, leveraging AI-driven analytics to identify and block it in real time, achieving a 56% higher prevention rate than competing vendors. Strong protection during the earliest stages of malware campaigns is critical, especially as AI accelerates the creation and spread of new malware.
• Complete phishing protection: Check Point led with 100% prevention of AI-powered phishing URLs in the evaluation, including previously unseen threats and those active within their first 24 hours in the wild.
• Protection against actively exploited vulnerabilities: Check Point leads with a 99.9% block rate of vulnerabilities in the CISA Known Exploited Vulnerabilities (KEV) catalog, as AI accelerates vulnerability discovery and weaponization. Other top vendors blocked 97.5%, 89.4%, and 87%, meaning Check Point had up to 130× fewer missed known exploited vulnerabilities.
• Reduced platform risk: With just one vulnerability, Check Point had up to 97% fewer reported vulnerabilities than leading competitors.
• Security that doesn’t slow you down: Check Point delivered the best user experience in the evaluation, leading competitors in both network speed and file download performance.

From Gaps to Resilience

Individual features matter, but outcomes depend on how well they work together. The system must stop threats early, detect and block in real time, reduce exposure to exploited vulnerabilities, and maintain performance across environments.

This is the difference between controls that work and a system that holds under pressure.

Bottom Line

AI is changing how attacks are executed, making them faster, broader, and more coordinated.

Security strategies must adapt to withstand combined pressure across the environment. This requires using AI to scale defense by automating intelligence, prevention, and remediation.

The real question is no longer if a gap exists.

It is how many gaps your network can survive.
