Check Point: October 2026 cyber landscape — record ransomware, GenAI data-leak risk, and AI-powered newcomer n0n rises

1 fonte(s) · 1 atualização(ões) · publicado 11/11/2026 10:00 · coletado há 1 hora

Check Point Research reports October 2026 saw a mixed month: weekly attack volumes fell 9% from September but remained 32% above October 2025, while ransomware reached a record 1,063 publicly reported incidents and a new actor, n0n, climbed into the top three (blog.checkpoint.com). High-risk use of generative AI also increased: 1 in 35 enterprise GenAI prompts posed a high risk of sensitive data leakage, affecting 90% of organizations that regularly use GenAI tools (blog.checkpoint.com). Phishing frequency eased (1 in 128 emails) though most phishing messages still delivered malicious links (79%), and education remained the single most-targeted sector. Check Point recommends prevention-first controls, AI-powered protection, consistent visibility and governance across networks, cloud, endpoints, email and AI services.

Detalhes técnicos

  • Average weekly attacks per organization: 2,550 in October 2026, down 9% month-over-month but up 32% year-over-year (blog.checkpoint.com).
  • Sector and regional highlights: Education highest at 5,934 weekly attacks/org; Agriculture surged 93% YOY; Africa recorded the highest regional volume (3,834 weekly attacks/org) and Europe recorded the fastest growth (up 39% YOY) (blog.checkpoint.com).
  • GenAI exposure: 1 in 35 enterprise GenAI prompts were high-risk for sensitive data leakage (2.9%), up from 2.5% in September; Financial, Legal/Regulatory and Network/IT Infrastructure data categories were commonly observed in risky prompts (blog.checkpoint.com).
  • Phishing: 1 in 128 emails classified as phishing in October; 79% of phishing emails contained links and 14% contained attachments (blog.checkpoint.com).
  • Ransomware: 1,063 publicly reported ransomware incidents in October (a 35% increase YOY); The Gentlemen led with 13% of published attacks, Qilin 12%, and n0n 8% after emerging in September and rapidly expanding (blog.checkpoint.com). The Gentlemen reportedly maintain access to pre-exploited FortiGate devices and target Windows, Linux and ESXi environments (blog.checkpoint.com).

Remediação

  • Adopt a prevention-first posture: strengthen visibility and governance for networks, cloud, endpoints, email and AI systems, apply least privilege and credential hygiene, and monitor for use of high-risk GenAI prompts and data exfiltration (blog.checkpoint.com).
