-> After you have managed to obtain credentials, you need to know **to who do those creds belong**, and **what they have access to**, so you need to perform some basic enumeration:
+> After obtaining credentials, determine **who they belong to** and **what they can access** before performing basic enumeration.
+
+## Evade Basic Detection
+
+Be aware that API requests made by the AWS CLI include details such as the operating system and version in the `User-Agent` header. CloudTrail records this information in API events, and detection services such as [GuardDuty](aws-services/aws-security-and-detection-services/aws-guardduty-enum.md) can use related activity for detection. Alerts may even be generated for operating systems commonly associated with security testing, such as Kali Linux or Parrot OS.
+
+For more information about the relevant logs and detections, see the [CloudTrail](aws-services/aws-security-and-detection-services/aws-cloudtrail-enum.md) and [GuardDuty](aws-services/aws-security-and-detection-services/aws-guardduty-enum.md) sections.
+
+### Override the AWS CLI User-Agent
+
+AWS CLI v2 supports Python plugins that can replace the complete `User-Agent`
+header on every request. This works with the installed `aws` executable and does
+not require patching or rebuilding it.
+
+AWS documents this interface in [AWS CLI Configuration Variables: Plugins](https://docs.aws.amazon.com/cli/latest/topic/config-vars.html#plugins). AWS describes CLI v2 plugin support as **"completely provisional"** and says that **"there are no guarantees that a particular plugin or even the CLI plugin interface will be supported in future versions of the AWS CLI v2."** In practice, the interface may change or be removed, so pin the AWS CLI version and test upgrades if you depend on this plugin.
+
+The AWS CLI reads `~/.aws/config` automatically, but it does not automatically import every Python module under `~/.aws`. The plugin system must be enabled explicitly in the global `[plugins]` section. AWS states that you **"must define the `cli_legacy_plugin_path` variable"** and that the CLI then loads each configured plugin by importing its Python module and calling `awscli_initialize`.
+
+Create the plugin as `~/.aws/plugins/user_agent_override.py`:
+```python
+import os
+
+def awscli_initialize(event_hooks):
+    def override_user_agent(request, **kwargs):
+        value = os.environ.get("USER_AGENT")
+        if value is not None:
+            request.headers["User-Agent"] = value
+
+    event_hooks.register_last("request-created", override_user_agent)
+```
+
+Add the directory and module to the global `[plugins]` section in
+`~/.aws/config`:
+
+```sh
+aws configure set plugins.cli_legacy_plugin_path "$HOME/.aws/plugins"
+aws configure set plugins.user_agent_override user_agent_override
+```
+
+The plugin is loaded for every AWS CLI invocation, but it changes the header only when `USER_AGENT` is set.
+
+You can test the override with:
+
+```shell
+export USER_AGENT="aws-cli-ua-test"
+aws --profile white-box-account sts get-caller-identity
+```
+
+Then inspect the event in CloudTrail. In the AWS Console, go to:
+
+```txt
+CloudTrail → Event history → Region us-east-1 → Event name GetCallerIdentity → JSON view
+```
+
+### Override Boto3 User-Agent restrictions
+
+If a policy restricts actions based on the `User-Agent`, such as blocking requests from Boto3, you can use the AWS Management Console in a browser or modify the Boto3 `User-Agent` with its `before-call` event hook.<sup>[[50]](#references)</sup>
+
+```python
+import boto3
+
+session = boto3.Session(profile_name="lab6")
+client = session.client("secretsmanager", region_name="us-east-1")
+
+client.meta.events.register(
+  "before-call.secretsmanager.GetSecretValue",
+  lambda params, **kwargs: params["headers"].update({"User-Agent": "my-custom-tool"}),
+)
+
+response = client.get_secret_value(SecretId="flag_secret")
+print(response["SecretString"])
+```
+
+This changes the Boto3 SDK request header for one operation; it does not change the AWS CLI user agent globally.
