False positive?

[datboi]

Hi, I’m just asking if MOSS is actually safe.
Anti-Virus detection:
https://www.virustotal.com/#/file/4fb0f76b62c208660e6b1b8a47d23332d627b9d264c54df5cfbdf80f5874e8ae/detection

Moss VM behaviour:

MOSS is mostly detected as Dropper Snojan, of which means that the AVs are detecting it as a PUP and a downloader, which is to be expected as the x86 version of MOSS is presumably running on an x64 VM. This is evident as it contacts these websites:

However the unexplained detections (not including generic, PUP, and downloader detections), such as Artemis!1A23AFD455F6 (A trojan that disables Task Manager, Folder Option, Registry and the command prompt by adding values to the registry key)

Thanks!

BTW: Here’s a Log of the VM:

well, first you are not allowed to attempt to reverse engineer Moss and even less to publish the content and URL, I removed the information from your post
then yes Moss acces to Internet to :
– auto update
– give me Google analytics anonimous stats
– give a server Date ( not a pc one)
– get the player public IP , traced in log on C class

nothing more , nothing less.

so no definitively it’s not a virus , trojan , adware or whatever.
it’s only based on windows API and a trusted ZIP lib, rest is my C code

[datboi]

OK, Thanks so much! Sorry for the inconvenience, I was not trying to reverse engineer MOSS, the URLs and IPs were in the log and I didn’t realise that they were there, so sorry for the confusion and sorry for the hassle. Thank you so much for clearing up the confusion! BTW, delete the post if you want to, cos the Virustotal and scan and VM URL is still there, there might be some sensitive stuff so you might wanna delete that. I’m really sorry about that.
