The Cyber Threat Landscape – Q3 2025 Summary

The Q3 2025 Threat Landscape Report shows continued evolution in ransomware operations, dark web activity, and exploit behavior, with a strong shift toward human-targeted attacks.

Key Findings

Ransomware

  • Overall ransomware activity declined 10.95%, but Qilin became the most active group.
  • Manufacturing and Professional Services were the most targeted industries.
  • Newer groups like NightSpire collapsed in activity.

Dark Web

  • Marketplace listings increased 5.63%, with 2.8M total listings.
  • Lumma infostealer dropped sharply; Acreed and Rhadamanthys surged, signaling attacker migration to newer variants.

Exploits

  • Exploit attempts rose 83.69%, driven by RAT botnets and a resurgence of old Linux DoS vulnerabilities.
  • Log4j, Bash RCE, and Hikvision CVE-2021-36260 remained heavily exploited.

Human-Focused Attacks

  • ClickFix became the second most common initial access method, relying on fake prompts that trick users into running malicious PowerShell commands.

Proactive Defense Strategies

  • Prioritize rapid patching of high-risk vulnerabilities.
  • Use EDR to detect ransomware and RAT behavior.
  • Maintain strong, tested backup processes.
  • Expand cybersecurity awareness training, especially around ClickFix techniques.
  • Monitor the dark web for leaked credentials and exposed data.
