list-attacks

Description

Returns all ongoing DDoS attacks or all DDoS attacks during a specified time period.

See also: AWS API Documentation

list-attacks is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: AttackSummaries

Options

--resource-arns (list)

The ARNs (Amazon Resource Names) of the resources that were attacked. If you leave this blank, all applicable resources for this account will be included.

(string)

Syntax:

"string" "string" ...

--start-time (structure)

The start of the time period for the attacks. This is a timestamp type. The request syntax listing for this call indicates a number type, but you can provide the time in any valid timestamp format setting.

FromInclusive -> (timestamp)

The start time, in Unix time in seconds.

ToExclusive -> (timestamp)

The end time, in Unix time in seconds.

Shorthand Syntax:

FromInclusive=timestamp,ToExclusive=timestamp

JSON Syntax:

{
  "FromInclusive": timestamp,
  "ToExclusive": timestamp
}

--end-time (structure)

The end of the time period for the attacks. This is a timestamp type. The request syntax listing for this call indicates a number type, but you can provide the time in any valid timestamp format setting.

FromInclusive -> (timestamp)

The start time, in Unix time in seconds.

ToExclusive -> (timestamp)

The end time, in Unix time in seconds.

Shorthand Syntax:

FromInclusive=timestamp,ToExclusive=timestamp

JSON Syntax:

{
  "FromInclusive": timestamp,
  "ToExclusive": timestamp
}

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json

  • text

  • table

  • yaml

  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on

  • off

  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64

  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To retrieve attack summaries from AWS Shield Advanced

The following list-attacks example retrieves summaries of attacks for the specified AWS CloudFront distribution during the specified time period. The response includes attack IDs that you can provide to the describe-attack command for detailed information on an attack.

aws shield list-attacks \
    --resource-arns arn:aws:cloudfront::12345678910:distribution/E1PXMP22ZVFAOR \
    --start-time FromInclusive=1529280000,ToExclusive=1529300000

Output:

{
    "AttackSummaries": [
        {
            "AttackId": "a1b2c3d4-5678-90ab-cdef-EXAMPLE11111",
            "ResourceArn": "arn:aws:cloudfront::123456789012:distribution/E1PXMP22ZVFAOR",
            "StartTime": 1529280000.0,
            "EndTime": 1529449200.0,
            "AttackVectors": [
                {
                    "VectorType": "SYN_FLOOD"
                }
            ]
        }
    ]
}

The end time of the attack, in Unix time in seconds.

AttackVectors -> (list)

The list of attacks for a specified time period.

(structure)

Describes the attack.

VectorType -> (string)

The attack type. Valid values:

  • UDP_TRAFFIC

  • UDP_FRAGMENT

NextToken -> (string)

When you request a list of objects from Shield Advanced, if the response does not include all of the remaining available objects, Shield Advanced includes a NextToken value in the response. You can retrieve the next batch of objects by requesting the list again and providing the token that was returned by the prior call in your request.

You can indicate the maximum number of objects that you want Shield Advanced to return for a single call with the MaxResults setting. Shield Advanced will not return more than MaxResults objects, but may return fewer, even if more objects are still available.

Whenever more objects remain that Shield Advanced has not yet returned to you, the response will include a NextToken value.
