ThePhish is an automated phishing email analysis tool based on TheHive, Cortex and MISP.

In this article, i will show you how to deploy the automated phishing analysis tool in AWS using Lightsail.

About ThePhish Tool,

  1. Any user can forward the suspicious email to the ThePhish for email analysis.
  2. ThePhish will also create a Ticket in TheHive and use Cortex Analyzer to analysis the email.
  3. Also, it will create the Event in MISP to publish the threat intel.
  4. User gets notification from ThePhish, the analyzed email is safe or malicious.

Installation,

For installation we can use Portainer Container Management tool to manage the Thephish, Thehive, Cortex and MISP containers and it is easy to deploy and manage.

Install Docker

we need docker to run the docker-compose files, so to install docker please run the following commands.

sudo apt-get updatesudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg-agent \
    software-properties-commoncurl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -sudo apt-key fingerprint 0EBFCD88sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"sudo apt-get updatesudo apt-get install docker-ce docker-ce-cli containerd.io docker-composesudo docker versionsudo usermod -aG docker $USER

Install Portainer

This container management tools make your life easier by managing all in single console.

Please execute the below commands to install Portainer.

mkdir -p /opt/portainer && cd /opt/portainercurl -L https://downloads.portainer.io/portainer-agent-stack.yml -o portainer-agent-stack.ymlNano portainer-agent-stack.yml 
Edit the ports like below
ports:
      - "19000:9000"
      - "18000:8000"docker stack deploy --compose-file=portainer-agent-stack.yml portainer

Create the Firewall rule in the LightSail as shown below

Now you can access the portainer <publicIp>:19000

After login — Click Stack and add stack

Portainer

After got the access, please go to stack option and Click add Stack.

Copy the docker-compose below link and paste in the web editor.

Integrate TheHive with Cortex

https://blog.agood.cloud/posts/2019/09/27/integrate-thehive-and-cortex/

Edit the cortex part of the file thehive/application.conf to replace the XXXXXXXXXXXXXXx with the API key of the integration_account created in Cortex.

play.modules.enabled += org.thp.thehive.connector.cortex.CortexModule
cortex {
  servers = [
    {
      name = local
      url = "http://cortex:9001"
      auth {
        type = "bearer"
        key = "XXXXXXXXXXXXXXx"
      }
      # HTTP client configuration (SSL and proxy)
      #  wsConfig {}
     # List TheHive organisation which can use this Cortex server. All ("*") by default
     # includedTheHiveOrganisations = ["*"]
     # List TheHive organisation which cannot use this Cortex server. None by default
     # excludedTheHiveOrganisations = []
    }
  ]
  # Check job update time intervalcortex
  refreshDelay = 5 seconds
  # Maximum number of successive errors before give up
  maxRetryOnError = 3
  # Check remote Cortex status time interval
  statusCheckInterval = 1 minute
}

Integrate TheHive with MISP

Edit the misp part of the file thehive/application.conf to replace the XXXXXXXXXXXXXXx with the Authentication key of the sync_user created in MISP.

# MISP configuration
play.modules.enabled += org.thp.thehive.connector.misp.MispModule
misp {
  interval: 5 min
  servers: [
    {
      name = "MISP THP"            # MISP name
      url = "https://misp/" # URL or MISP
      auth {
        type = key
        key = "XXXXXXXXXXXXXXx"             # MISP API key
      }
      wsConfig { ssl { loose { acceptAnyCertificate: true } } }
    }
  ]
}

Configure the TheHive container

  1. Go to http://localhost:9000 and log in with the default credentials:
  • Username: admin@thehive.local
  • Password: secret
  1. Create a new organization
  2. Click on “New organization”
  3. Name: <YourOrganizationName>
  4. Description: <YourOrganizationDescription>
  5. Create a new orgadmin user in that organization
  6. Click on the newly created organization <YourOrganizationName>
  7. Click on “Create new user”
  8. Login: thephish@<YourOrganizationName>
  9. Full name: ThePhish
  10. Profile: org-admin
  11. Click on “New password” for the newly created user and set a password for that user
  12. Click on “Create API key” and then on “Reveal” for the newly created user and save it for later
  13. Log out the admin user and log in the orgadmin user (ThePhish)

Configure the ThePhish container

The file configuration.json is the global configuration file that allows setting the parameters for the connection to the mailbox and to the instances of TheHive, Cortex and MISP. It also allows setting parameters related to the cases that will be created on TheHive.

{
	"imap" : {
		"host" : "imap.gmail.com",
		"port" : "993",
		"user" : "",
		"password" : "",
		"folder" : "inbox"
	},
	"thehive" : {
		"url" : "http://thehive:9000",
		"apikey" : ""
	},
	"cortex" : {
		"url" : "http://cortex:9001",
		"apikey" : "",
		"id" : "local"
	},
	"misp" : {
		"id" : "MISP THP"
	},
	"case" : {
		"tlp" : "2",
		"pap" : "2",
		"tags" : ["email", "ThePhish"]
	}
}
  • In the imap part, if you are using a Gmail address, you only need to set the username used to connect to the IMAP server (which is your email address) and the app password.
  • In the thehive part you have to set the URL at which the TheHive instance is reachable and set the API key of the user created on TheHive that ThePhish will use to interact with TheHive.
  • In the cortex part you have to set the URL at which the Cortex instance is reachable and set the API key of the user created on Cortex that both ThePhish and TheHive will use to interact with Cortex. Moreover, you have to set the ID given to the Cortex instance.
  • In the misp part you only have to set the ID given to the MISP instance.
  • In the case part you can set the default TLP and PAP levels for the cases created by ThePhish and also the tags that will be applied to them at their creation.
