Thread-Log: Virus found

[w.naderer]

Hello,
under our Threat-Log I found some Virus entries. The Attacker is an own PC from another vlan. We want to install windows updates over Ivanti-Patchmanagement with the original windows update service. And now the maschine, which we will patch, will do a virus attack - msiexec.exe and wscript.exe. Palo ID 194147259, Application ms-ds-smbv2...
We scanned both machines with a lot of tools and virus-scanner = nothing found!!!
Can somebody tell me the location of the infected files, which will shown in the thread log?
Have you some Tips for me?
Thank you verry much.

Cu
Wolfgang

Wolfgang,

 They weren't false positives. False positives are when WildFire gives a Benign file a Malicious verdict.

 In this case, WildFire gave the files a Benign verdict, but they were triggering Antivirus signatures. We call these Signature Collisions. These happen when the digital patterns that the firewall looks at to identify a file, concide between a Benign sample and an Antivirus signature that has been generated from a Malicious sample that is similar in structure to the Benign file.

It was a virus false report caused by a Signature Collision.

Hi Mivaldi,

I will try it...but I can't directly open a case 😞

I must go to our reseller and they must open a case over an Sub-Company?!?

Thank you
