## Goal{% #goal %}

Detect when a user consents to an application associated with business email compromise.

## Strategy{% #strategy %}

Monitor Microsoft 365 Exchange audit logs to look for the operation `Consent to application.`. Attackers who have gained unauthorized access to a victim's account may add applications in order to collect emails or send out further phishing emails. In this detection, we try to identify the following applications:

- eM Client - a desktop email client with full Microsoft Office 365 synchronization.
- PerfectData Software - exports mailboxes for backup purposes.
- Newsletter Software Supermailer - email newsletter software to send out high volume emails.
- SigParser - email signature contact scraping and parsing.
- CloudSponge - allows you to export all contacts from an inbox.
- rclone - is a command-line program to manage files on cloud storage.

## Triage and response{% #triage-and-response %}

1. Identify any additional unusual behaviors:
   - Previous failed logins.
   - Anomalous geo-location.
   - VPN usage.
1. Determine if there is a legitimate use case for the new application by contacting the user `{{@usr.email}}`.
1. If `{{@usr.email}}` is not aware of the application:
   - Investigate other activities performed by the user `{{@usr.email}}` using the **Cloud SIEM - User Investigation** dashboard.
   - Begin your organization's incident response process and investigate.
