Threat Landscape: Who's Attacking?
Nation-State Actors
Chinese-aligned APTs — including Linen Typhoon (APT27), Violet Typhoon (APT31), and Salt Typhoon — exploited the SharePoint "ToolShell" zero-day in 2025, compromising 396 confirmed systems. China-nexus groups now dominate edge-device exploitation.
Ransomware Gangs
Qilin surged to #1 in 2025 with 1,000+ victims — a 408% YoY spike — absorbing former RansomHub affiliates. Akira, Cl0p, and newcomer Sinobi round out the most dangerous RaaS operations. The ecosystem now spans 138 named groups.
Scattered Collectives
Less-structured groups like Scattered Spider and ShinyHunters grabbed major 2025 headlines, deploying DragonForce ransomware against M&S and the Co-op, causing hundreds of millions in losses — proving credentials and social engineering remain devastating vectors.
Critical Vulnerabilities: June 2025
In 2025, 48,185 CVEs were published — a 20.6% YoY increase averaging 133 new vulnerabilities per day. Prioritize patching based on exploitability in the wild. Nearly 1 in 3 exploits now occur within 24 hours of CVE disclosure.
Chapter 2
Breaches & Incidents
Major security incidents making headlines in 2025 — and the lessons every organization must take away.
Notable Breaches: By the Numbers
Credentials Exposed
The largest credential compilation breach ever recorded — discovered June 2025, covering Google, Apple, banking, and enterprise accounts
Avg. Breach Cost
IBM's 2025 Cost of a Data Breach Report — global average, down slightly from 2024's record. U.S. organizations average a staggering $10.22M
Ransomware Surge
Year-over-year increase in ransomware victims in 2025 — the most active year ever recorded, with 7,515 claimed victims globally
AI-Enabled Attacks
CrowdStrike 2026 Global Threat Report: year-over-year increase in attacks by AI-enabled adversaries, with eCrime breakout time dropping to just 27 seconds
Ransomware: A Closer Look
Key Insight: 2025 Shift
Modern ransomware attacks are multi-stage, AI-accelerated operations. In 2025, data encryption occurred in only 50% of attacks — the lowest in six years — as groups increasingly rely on data theft and extortion alone. 138 distinct named groups operated in 2025, a 41% increase over 2024.
Defensive Strategies That Work
Zero Trust Architecture
Never trust, always verify. Enforce least-privilege access across every user, device, and network segment. Identity-first segmentation is now essential — most 2025 breaches originated with stolen credentials or social engineering.
Phishing-Resistant MFA
Deploy FIDO2/passkey authentication wherever possible. Credential abuse remains the #1 breach vector (22% of incidents). Standard MFA is increasingly bypassed by adversarial AI and MFA-fatigue attacks — upgrade to hardware keys.
AI-Powered Threat Detection
Invest in EDR/XDR platforms with AI-driven behavioral analytics and 24/7 SOC monitoring. IBM found organizations with extensive AI security saved over $2M per breach. With eCrime breakout at 27 seconds, automated response is no longer optional.
Emerging Threats to Watch
AI-Weaponized Attacks
In 2025, AI-enabled adversary attacks surged 89% YoY. Attackers use generative AI for hyper-personalized phishing, polymorphic malware, and automated zero-day discovery. ChatGPT is referenced in criminal forums 550% more than any other model — and 87% of respondents say AI vulnerabilities are the fastest-growing cyber risk.
Supply Chain Attacks
54% of large organizations cite supply chain risk as their biggest barrier to cyber resilience. The 2025 Oracle EBS zero-day (CVE-2025-61882) and SharePoint ToolShell attacks demonstrated how a single vendor flaw can cascade across thousands of organizations. Software bill of materials (SBOM) and continuous vendor vetting are now mandatory.
Post-Quantum Threats
Quantum computing threatens today's encryption standards. NIST has finalized its first post-quantum cryptographic algorithms — organizations should begin migration planning now. Meanwhile, "harvest now, decrypt later" attacks by nation-state actors make long-lived sensitive data vulnerable today.
Your Action Plan
Key Takeaways & Next Steps
Patch Immediately
Prioritize CVE-2025-33053, CVE-2025-33070, and CVE-2025-53770 — all actively exploited in the wild
Upgrade to Passkeys
Replace legacy MFA with FIDO2/passkeys — credential abuse drives 22% of all 2025 breaches
Automate Detection
Deploy AI-powered EDR/XDR — with eCrime breakout now at 27 seconds, human-only response is too slow
Train for AI Phishing
Run AI-generated phishing simulations — adversaries now craft hyper-personalized lures at scale
"The question is no longer if you will be targeted — it's when. Organizations that invest in preparation, not just protection, are the ones that survive."
In 2025, the average time-to-exploit turned negative — attackers move before patches exist. With 48,185 CVEs published this year and AI supercharging attacker capabilities, security must be a continuous, organization-wide priority — not a one-time project.
