# BazaCall Excel file download domain pattern
BazaCall is a campaign that manipulate users into calling a customer support center, where they are instructed to download an Excel file to unsubscribe from a phony service. When the user opens the Excel file, they are prompted to enable a malicious macro that infects their device with BazaLoader.
This query hunts for an attacker-created copy of *certutil.exe*, a legitimate process, which the macro uses to download BazaLoader.
## Query
```kusto
DeviceFileEvents
| where InitiatingProcessFileName !~ "certutil.exe"
| where InitiatingProcessFileName !~ "cmd.exe"
| where InitiatingProcessCommandLine has_all("-urlcache", "split", "http")
```
## Category
This query can be used to detect the following attack techniques and tactics ([see MITRE ATT&CK framework](https://attack.mitre.org/)) or security configuration states.
| Technique, tactic, or state | Covered? (v=yes) | Notes |

| Initial access | v | |

| Privilege escalation | | |
| Defense evasion | v | |
| Credential Access | | |
| Discovery | | |
| Lateral movement | | |

This query surfaces connections to the distinctive *.xyz* domains that the BazaCall campaign uses to host malicious Excel files.
## Query
```kusto
