B seems pretty safe, HTML can't do much on its own.
DE

Surprised that people still open attachments without checking!
KA

A lot of malware comes from email, so I agree with D.
GE

I think C is riskier, especially if the source isn't verified.

Definitely D, those email attachments are sketchy!

Opening email attachments seems like the most obvious risk to me. I recall a case study where that led to a major breach.

I think uploading files to an internal server is generally safe, but I’m not confident about that. We had a practice question on this, and I’m still a bit confused.
SI

I’m not entirely sure, but I feel like downloading files from an enterprise share could also introduce malware if the files are compromised.
LA
Launa 12 months ago
I remember we discussed how opening email attachments can be risky, especially from unknown sources. I think that might be the answer.
TR

D has got to be the right answer. Email attachments from outside the organization are a classic way for malware to get in. Gotta be really careful with those.
KA

I'm leaning towards A. Uploading a file to an internal server seems like it could easily spread malware across the network if the file is compromised.
JA

Hmm, I'm not sure. Uploading a file to an internal server could also be risky if it's infected. I'll have to think this through carefully.
AL

I think the answer is D. Opening an email attachment from an external account seems like the biggest risk for malware, since you don't know what's in that attachment.

Gotta be option D. Opening email attachments is like playing Russian roulette with your network security. I'd rather wrestle a hungry lion than click on one of those things.

Hmm, I'm torn between B and D. Viewing HTML docs can be risky, but those email attachments are just begging to unleash a virus. Maybe I should start using a hazmat suit for my daily email check.

But downloading a file from an enterprise file share could also introduce malware, right?
