Top Threats 2025

Understanding the threat landscape is foundational to every security program. These are the highest-prevalence attack categories tracked across enterprise environments this year.

Ransomware & Double Extortion 92%
Phishing & Social Engineering 88%
Supply Chain Attacks 74%
Credential Theft & Stuffing 71%
Cloud Misconfiguration 68%
AI-Assisted Attacks 55%
Zero-Day Exploitation 44%

2025 Threat Reality Check

Cybercrime is projected to cost the global economy $9.5 trillion USD in 2025 — more than the GDP of every country except the U.S. and China.

The average cost of a data breach reached $4.88M USD in 2024 (IBM Cost of a Data Breach Report). Ransomware attacks now occur every 11 seconds globally.

Organizations without a documented Incident Response plan pay an average of $2.66M more per breach than those with a tested plan.

MITRE ATT&CK Framework

attack.mitre.org is the definitive knowledge base of adversary tactics, techniques, and procedures (TTPs) organized into 14 tactical categories.

All major SIEMs and threat intelligence platforms support ATT&CK mappings. Teams use it to measure detection coverage and communicate about adversary behavior in a consistent, standardized language.


OWASP Top 10 — Web Vulnerabilities

The OWASP Top 10 is the definitive standard reference for web application security risks. Every developer and security professional should be fluent in all 10 categories.

# Vulnerability Example Attack Primary Defense Severity
A01 Broken Access Control Modifying URL parameter to access another user’s data Server-side access checks; deny by default Critical
A02 Cryptographic Failures Passwords in cleartext; MD5 hashing TLS everywhere; bcrypt / Argon2; AES-256 at rest Critical
A03 Injection (SQLi, XSS) ' OR 1=1-- in login; script tags in user input Parameterized queries; input validation; output encoding Critical
A04 Insecure Design No rate limiting on login; reset reveals user existence Threat modeling; secure design patterns High
A05 Security Misconfiguration Default credentials; directory listing; verbose error messages Hardening guides; automated config scanning High
A06 Vulnerable Components Log4Shell (CVE-2021-44228); outdated npm packages SBOM; SCA scanning (Snyk, Dependabot); patch fast High
A07 Auth & Session Failures Weak passwords; session tokens in URLs MFA; secure cookies; proper session invalidation High
A08 Software Integrity Failures Supply chain injection (SolarWinds); insecure auto-updates Code signing; dependency pinning; CI/CD security High
A09 Logging & Monitoring Failures No SIEM alerting on repeated failed logins Centralized logging; alert on anomalies; test detection Medium
A10 SSRF Server forced to query cloud metadata endpoint Allowlist outbound resources; block metadata IPs Medium

Major Security Frameworks

Most organizations must comply with multiple overlapping frameworks simultaneously. A single control often satisfies NIST, CIS, ISO, PCI DSS, and HIPAA simultaneously — enabling significant compliance efficiency.
