Might have bypassed Checkpoint since it emulated the zip file which was packed. Also light work for kaspersky lol

Its able to emulate still. Maybe @Trident can check. I'm on ChromeOS.

Even if its in a zip where its packed?

Yes they use common passwords also to decrypt.

I feel like its different since its in a zip - You know how something in a zip may not be picked up by a scanner, but out of the zip it does? It might be like that

It pulls the file out of the zip and executes it.

BD GZ Sandbox UI is the best, shame you can't export the report. I took a full screen photo using a chrome/edge extension, but there are still some things missing in the photo because you have to scroll...

Since when does LiveGuard have such an UI?

 

[Trident]

The sample was blocked by behavioral guard immediately after launch and was deleted.

Seems that the command server is down (at least for me). But one can redo this vbs downloader as a batch that will give similar joy:

Scriptor:
VirusTotal

With the Powershell command yielding:
VirusTotal

Often one can't gain much insight from VT without running the malware.

I wanna see if Threat Emulation does anything, can u try to turn everything off besides threat emulation and see how that goes?

Kaspersky PDM module blocked it before. Now they pushed a sig. Sweet.

Kaspersky PDM module blocked it before. Now they pushed a sig. Sweet.

They had 7-8 signatures before the file was uploaded, according to opentip.

 

[Sandbox Breaker]

At first I only saw PDM sig. Which is their ML.
