D) data diddling doesn’t fit here at all.

I feel like A) deobfuscation could be relevant too, but not the main task.

No way it's XML injection, that's not even relevant here!

XML injection? Nah, I'm not trying to hack the system, just scan some memory.

I'm leaning towards string matching as the answer, but I wonder if there's a chance it could be something else like data diddling? That one sounds familiar too.

I feel like deobfuscation might be related, but it seems more about analyzing code rather than scanning memory directly.

I think we practiced a similar question where string matching was definitely involved, but I can't recall if it was specifically for memory scanning.

I remember learning about YARA in class. I'm pretty sure it's used for identifying malware by looking for specific patterns or strings in memory. So I think the answer is C) string matching.

Ugh, I'm totally lost on this one. What's a YARA rule? And how does that relate to scanning memory? I'm going to have to guess on this one.

Okay, I know YARA is used for pattern matching, so I'm guessing the answer has to do with that. Maybe C) string matching? I'll double-check my notes to be sure.

Hmm, I'm a little unsure about this one. Is it asking about how to actually run the YARA scan, or just what the purpose of YARA is? I'll have to think this through carefully.
