Code obfuscation techniques

Hex Encoding (IIS and Apache) Hex encoding is the simplest of the URL obfuscation techniques. The attacker simply replaces a character with its ASCII equivalent in hexadecimal, prefaced by a percent sign.

Three of the most common techniques used to obfuscate data are encryption, tokenization, and data masking . Encryption, tokenization, and data masking work in different ways. Encryption and tokenization are reversible in that the original values can be derived from the obfuscated data.

Malware obfuscation is a process that makes textual and binary data difficult to understand . Obfuscation techniques are used by attackers to make it difficult for antivirus to detect filterless malware. Malware evolves their body into new generations through the obfuscation technique to be able to evade antivirus.

Obfuscation means to make something difficult to understand . Programming code is often obfuscated to protect intellectual property or trade secrets, and to prevent an attacker from reverse engineering a proprietary software program. Encrypting some or all of a program’s code is one obfuscation method.
