analyzing-ransomware-encryption-mechanisms
Analyzes encryption algorithms, key management, and file encryption routines used by ransomware families to assess decryption feasibility, identify implementation weaknesses, and support recovery efforts. Covers AES, RSA, ChaCha20, and hybrid encryption schemes. Activates for requests involving ransomware cryptanalysis, encryption analysis, key recovery assessment, or ransomware decryption feasibility.

# Analyzing Ransomware Encryption Mechanisms
## When to Use
- A ransomware infection has occurred and recovery requires understanding the encryption scheme used
- Assessing whether decryption is possible without paying the ransom (implementation flaws, known decryptors)
- Reverse engineering ransomware to identify the encryption algorithm, key derivation, and key storage mechanism
- Developing a decryptor tool when a weakness in the ransomware's cryptographic implementation is identified
- Classifying a ransomware sample by its encryption approach to attribute it to a known family
**Do not use** for production data recovery operations without first verifying the decryption method on test copies of encrypted files.
