Cryptographic Failures

Failures related to cryptography which often lead to sensitive data exposure. This includes using weak algorithms, improper key management, and missing encryption.

Aperçu

Dropped to #4 from #2. Focuses on failures related to cryptography which often leads to sensitive data exposure or system compromise. 3.80% incidence rate across tested applications.

Comment les Attaquants Exploitent Cela

Comprendre les patterns d'attaque vous aide à construire de meilleures défenses. Ce sont les techniques que les équipes de sécurité surveillent.

Data exposure in transit

Sensitive data transmitted over unencrypted connections can be intercepted. This includes passwords, session tokens, and personal information.

Signal de détection: HTTP (not HTTPS) requests containing authentication data or sensitive information

Weak cryptographic storage

Data stored with weak or broken encryption (MD5, SHA1, DES) can be recovered by attackers who gain database access.

Signal de détection: Database dumps containing hashed passwords with known weak algorithms

Hardcoded secrets

API keys, passwords, or encryption keys embedded in source code can be extracted from repositories or compiled binaries.

Signal de détection: Secrets in version control history, keys matching known patterns in code

Comment Prévenir

  • Classify data processed, stored, or transmitted by an application
  • Don't store sensitive data unnecessarily
  • Encrypt all sensitive data at rest using modern algorithms
  • Use up-to-date and strong standard algorithms and protocols
  • Encrypt all data in transit with secure protocols such as TLS 1.3
  • Disable caching for responses containing sensitive data
  • Store passwords using strong salted hashing functions (Argon2, bcrypt, scrypt)
