### Description

Multiple suspicious FTP sessions were detected, which may indicate a brute-force attempt.

### Attacker's Goals

Attackers may seek access to FTP accounts and use them to exfiltrate data, stage attack tools, or create command and control channels through trusted services.

### Investigative actions

* Examine the legitimacy of the application that produced this uncommon FTP connection.
* Examine the parent process of this application.
* Verify that the connection attempts were not performed from an illegitimate source.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/analytics-alerts/alerts-by-name/multiple-suspicious-ftp-login-attempts.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
