摘要:
The disclosed computer-implemented method for recovering encrypted information may include (i) identifying an untrusted application that uses a known cryptographic function, (ii) hooking the known cryptographic function used by the untrusted application to execute decryption-facilitation code when the untrusted application attempts to encrypt data, where the decryption-facilitation code reduces the difficulty of later decrypting data encrypted by the untrusted application, (iii) detecting encrypted data produced by the untrusted application, and (iv) recovering unencrypted data from the encrypted data produced by the untrusted application using a decryption technique facilitated by having executed the decryption-facilitation code that reduced the difficulty of later decrypting the encrypted data encrypted by the untrusted application. Various other methods, systems, and computer-readable media are also disclosed.
