Hi, my name is Julian and i created a file checker for email attachments.

In my former 9-5 i worked as a it support engineer in a small to medium sized company. Our team was therfore also kinda responsible for security. We would get about 5 requests per day to check some sort of weird email attachment someone from the company received.

The problem was that we sometimes were not entirly sure if it contains malware or not and had no proper tools to check. Also, everybody from our team would handle a specific case differently - making it kinda dangerous.

Therefore i created Mailthreat. The user forwards the suspicious mail, the tool runs multiple checks on the files attached, then the sender gets back a result for the files.

Tell me what you think!

Since my test e-mails from a throwaway don't seem to go through: What checks does this perform? Since the policy pages don't name third parties like virustotal I assume it runs some OSS tools on your side?

Regarding the privacy policy and ToS: How do you see people using this in a corporate setting vs. something local? Most suspicious e-mail I encounter can't just be sent to random third parties.

sidenote: Some of the text is gray on gray and barely visible, e.g. on the main overview page when logged in and your policy pages.

-) Throwaway indeed doesnt go through. Have to have a look on that. I assume that most users forward from a legit mail tough.

-) Regarding checks, we use clamav and open the file in a sandbox for preview (for example archives like .zip

-) Regarding privacy, valid point. Tough the usp of the tool is the simplicity, so no installation etc. If it is a problem for most corporate settings we have to adapt.

Thanks for your feedback

I like it, of course, but don’t Gmail and similar services offer this ?

Gmail as far as i know yes. But i am not aware which other providers and to what extent. There are additional features planned (for example link checker). We want to offer a complete solution for mails.
