Compromised certificate [Nobelium]

# Compromised certificate [Nobelium]

Search for the files that are using a compromised certificate associated with the Nobelium campaign.

You can remove the comments to:

* get the list of devices where there is at least one file signed with the certificate
* get the list of files signed with the certificate
* get the list of files signed with the certificate group by Devices

## Query

```Kusto
DeviceFileCertificateInfo
| where Signer == 'Solarwinds Worldwide, LLC' and SignerHash == '47d92d49e6f7f296260da1af355f941eb25360c4'
| join DeviceFileEvents on SHA1
| distinct DeviceName, FileName, FolderPath, SHA1, SHA256, IsTrusted, IsRootSignerMicrosoft, SignerHash
//| distinct DeviceName
//| distinct FileName
//| summarize mylist = make_list(FileName) by DeviceName
```
