String Encryption

Obfuscation of sensitive strings is an essential security practice to make reverse engineering and static analysis of applications more difficult. Plaintext strings, such as API URLs, public keys, error messages, internal identifiers, or queries, often provide valuable clues about the application's architecture, flows, and business rules, serving as a starting point for malicious analysis.

Technical Mechanism: MAD protects sensitive strings by preventing strategic textual information from being available in a readable form within the application's binary. These strings are stored in a protected manner and only become accessible during execution, at the exact moment they are needed. This approach significantly reduces the exposure of critical information during static inspections of the binary, making automated extraction of sensitive data more difficult and limiting the use of common reverse engineering tools.
