👉 Spyware often employs sophisticated mathematical techniques to evade detection and maintain persistence on a system. One common method involves using encryption algorithms, such as AES (Advanced Encryption Standard), to obfuscate its communication with command-and-control servers, making it difficult for security software to intercept and analyze. Additionally, spyware may use randomized or pseudo-random values in its code, such as initialization vectors and nonces, to create unique signatures that change with each execution, further complicating signature-based detection. Another technique is the use of mathematical heuristics to mimic legitimate user behavior, such as timing and resource usage patterns, to blend in with normal system activity. These methods collectively enhance the spyware's stealth and resilience against security measures.
