Heather, a computer forensics investigator, is assisting a group of investigators working on a large computer fraud case involving over 20 people. These 20 people, working in different offices, allegedly siphoned off money from many different client accounts. Heather responsibility is to find out how the accused people communicated between each other. She has searched their email and their computers and has not found any useful evidence. Heather then finds some possibly useful evidence under the desk of one of the accused.

In an envelope she finds a piece of plastic with numerous holes cut out of it. Heather then finds the same exact piece of plastic with holes at many of the other accused peoples desks. Heather believes that the 20 people involved in the case were using a cipher to send secret messages in between each other. What type of cipher was used by the accused in this case?

Wait, are they really using a cipher? Seems a bit old school.

I think it's a null cipher. Those holes are a classic!

Sounds like a grill cipher to me!

Not sure about that... could just be a coincidence with the plastic.

Definitely a visual semagram, right?

I have a vague memory of the text semagram, but I can't recall how it specifically relates to this scenario.

I practiced a similar question about visual ciphers, but I don't think that's what they're using here.

I'm not entirely sure, but I feel like the null cipher could also fit because it hides messages within plain text.

I remember studying different types of ciphers, and I think the grill cipher might be the right answer since it involves using a grid-like structure.

I feel pretty confident about this one. The description of the plastic with holes points to some kind of visual cipher, and the options given seem to match that. I'm going to go with the visual semagram as my final answer.

Alright, I've got a strategy here. The key is to understand how the plastic with holes could be used to secretly communicate. I'm leaning towards either the grill cipher or the visual semagram, but I'll need to carefully consider the differences between those options.

I'm a bit confused by this question. The information about the plastic with holes is interesting, but I'm not sure how to connect that to the specific types of ciphers listed as the answer choices. I'll need to think this through step-by-step.

Okay, let's see. The plastic with holes found at multiple desks suggests some kind of visual cipher. I'm thinking it could be a text or visual semagram, but I'll need to review the options to be sure.

Hmm, this seems like a tricky one. I'll need to carefully analyze the details about the piece of plastic with holes to determine the type of cipher used.

I'm going with the null cipher. Hiding messages in innocuous-looking documents? That's the kind of low-tech, high-impact strategy these guys would go for.

I agree, the accused probably thought they were being clever by using such a basic method to communicate secretly.

Null cipher seems like a good guess. It's simple yet effective in hiding messages.

Haha, a 'visual semagram'? What is this, a spy novel? Definitely the grill cipher. Classic choice for these kinds of covert operations.

Text semagram? No way, that's too elaborate for this case. Gotta be the null cipher. Hiding messages in plain sight, that's the way to go.

I don't think the grill cipher fits the scenario, the null cipher seems more practical.

Visual semagram? Really? That's way too obvious for a group of financial criminals. I'd go with the null cipher - it's simple, effective, and hard to detect.
