API Key Result

Create an intake

Go to the intake page and create a new intake from the format Bitdefender GravityZone. Copy the intake key.

Set the push events settings

Bitdefender GravityZone have an ability to setup push events settings using http request.

Two ways are suggested in order to set up the forwarding of your events to Sekoia.io.

If you are not a shell expert, we recommend to use the "pyton script" way as it is easier to set up.

So you can setup it in two ways:

  1. Open terminal
  2. Create virtual env and install requests library:
      $ python3 -m venv /tmp/venv
      $ /tmp/venv/bin/pip install requests
    
  3. Export your API Key and Intake key to environment variables:
      $ export BITDEFENDER_APIKEY="your_api_key"
      $ export SEKOIAIO_INTAKE_KEY="your_intake_key"
    
  4. Create python script with the following content:
    import base64
    import sys
    import argparse
    
    import requests
    
    
    BITDEFENDER_PUSH_URL = "https://cloudgz.gravityzone.bitdefender.com/api/v1.0/jsonrpc/push"
    
    def activate_forwarding(apikey: str, intake_key: str):
        key = base64.b64encode(b':'+intake_key.encode('utf-8'))
    
        payload = {
          "id": "be630db8-24c2-481c-b150-a79807dd6f7d",
          "jsonrpc": "2.0",
          "method": "setPushEventSettings",
          "params": {

              "uninstall": False
            }
          }
        }
    
        response = requests.post(
            url=BITDEFENDER_PUSH_URL,
            auth=requests.auth.HTTPBasicAuth(apikey,""),
            json=payload,
        )
        if response.status_code == 200:
            setting_id = response.json().get("id")
            print(f"The push setting was successfully created. ID: {setting_id}")
        else:
            print(f"The creation of the forwarding failed. Reason: {response.content}")
    
    
    if __name__ == '__main__':
        parser = argparse.ArgumentParser(prog=sys.argv[0], description='activate the forwarding of events to Sekoia.io')
        parser.add_argument('apikey')
        parser.add_argument('intake_key')
        args = parser.parse_args()
        activate_forwarding(args.apikey, args.intake_key)
    
  5. Run the script with the following command:
      $ /tmp/venv/bin/python3 bitdefender_activate_forwarding.py "${BITDEFENDER_APIKEY}" "${SEKOIAIO_INTAKE_KEY}"
    
  1. Open your terminal
  2. Export your API Key and Intake key to environment variables:
      $ export BITDEFENDER_APIKEY="your_api_key"
      $ export SEKOIAIO_INTAKE_KEY="your_intake_key"
    
  3. Convert the Bitdefender APIKey into base64:
      $ echo -n '${BITDEFENDER_APIKEY}:' | base64
    
  4. Convert the Intake Key into base64:
      $ echo -n ':${SEKOIA_INTAKE_KEY}' | base64
    
  5. Create payload.json with following content ( replace base64_intake_key with the value from the previous steps):
    {

Detection section

The following section provides information for those who wish to learn more about the detection capabilities enabled by collecting this intake. It includes details about the built-in rule catalog, event categories, and ECS fields extracted from raw events. This is essential for users aiming to create custom detection rules, perform hunting activities, or pivot in the events page.

The following Sekoia.io built-in rules match the intake Bitdefender GravityZone [BETA]. This documentation is updated automatically and is based solely on the fields used by the intake which are checked against our rules. This means that some rules will be listed but might not be relevant with the intake.

CVE-2020-0688 Microsoft Exchange Server Exploit

Detects the exploitation of CVE-2020-0688. The POC exploit a .NET serialization vulnerability in the Exchange Control Panel (ECP) web page. The vulnerability is due to Microsoft Exchange Server not randomizing the keys on a per-installation basis resulting in them using the same validationKey and decryptionKey values. With knowledge of these, values an attacker can craft a special viewstate to use an OS command to be executed by NT_AUTHORITY\SYSTEM using .NET deserialization. To exploit this vulnerability, an attacker needs to leverage the credentials of an account it had already compromised to authenticate to OWA.

Note - Clever attackers may easily bypass this detection by just renaming the driver filename. Therefore just Medium-level and don't rely on it.

  • Effort: advanced
Suspicious TOR Gateway

Detects suspicious TOR gateways. Gateways are often used by the victim to pay and decrypt the encrypted files without installing TOR. Tor intercepts the network traffic from one or more apps on user’s computer, usually the user web browser, and shuffles it through a number of randomly-chosen computers before passing it on to its destination. This disguises user location, and makes it harder for servers to pick him/her out on repeat visits, or to tie together separate visits to different sites, this making tracking and surveillance more difficult. Before a network packet starts its journey, user’s computer chooses a random list of relays and repeatedly encrypts the data in multiple layers, like an onion. Each relay knows only enough to strip off the outermost layer of encryption, before passing what’s left on to the next relay in the list.

  • Effort: advanced
Suspicious URI Used In A Lazarus Campaign

Detects suspicious requests to a specific URI, usually on an .asp page. The website is often compromised.

  • Effort: intermediate
TOR Usage Generic Rule

Detects TOR usage globally, whether the IP is a destination or source. TOR is short for The Onion Router, and it gets its name from how it works. TOR intercepts the network traffic from one or more apps on user’s computer, usually the user web browser, and shuffles it through a number of randomly-chosen computers before passing it on to its destination. This disguises user location, and makes it harder for servers to pick him/her out on repeat visits, or to tie together separate visits to different sites, this making tracking and surveillance more difficult. Before a network packet starts its journey, user’s computer chooses a random list of relays and repeatedly encrypts the data in multiple layers, like an onion.
