The development of the Thundersoft Decryptor was made possible by two specific implementation errors in the malware code identified in versions 1.0 through 1.2.

| Component | Function | |-----------|----------| | scanner.exe | Scans local drives for files with .thunder extension and builds a manifest. | | crypto_analyzer.dll | Detects IV reuse patterns by comparing first 16 bytes of ciphertexts. | | key_recovery_module | If a known plaintext is supplied (e.g., a default template file), derives the AES key via XOR differential analysis. | | bulk_decryptor | Decrypts files in parallel using AVX-512 instructions for high throughput. |
