A software scanner identifies a region within a binary image having high entropy. What does this MOST likely indicate?
Correct Answer: C
Obfuscated code is a type of code that is deliberately written or modified to make it difficult to understand or reverse engineer3. Obfuscation techniques can include changing variable names, removing comments, adding irrelevant code, or encrypting parts of the code. Obfuscated code can have high entropy, which means that it has a high degree of randomness or unpredictability4. A software scanner can identify a region within a binary image having high entropy as a possible indication of obfuscated code. Encryption routines, random number generators, and botnet command and control are not necessarily related to obfuscated code, and may not have high entropy.
