Instruction on Sekoia

Configure Your Intake

This section will guide you through creating the intake object in Sekoia, which provides a unique identifier called the "Intake key." The Intake key is essential for later configuration, as it references the Community, Entity, and Parser (Intake Format) used when receiving raw events on Sekoia.

  1. Go to the Sekoia Intake page.
  2. Click on the + New Intake button at the top right of the page.
  3. Search for your Intake by the product name in the search bar.
  4. Give it a Name and associate it with an Entity (and a Community if using multi-tenant mode).
  5. Click on Create.

Note

For more details on how to use the Intake page and to find the Intake key you just created, refer to this documentation.

Configure Your Playbook

This section will assist you in pulling remote logs from Sekoia and sending them to the intake you previously created.

  1. Go to the Sekoia playbook page.
  2. Click on the + New playbook button at the top right of the page.
  3. Select Create a playbook from scratch, and click Next.
  4. Give it a Name and a Description, and click Next.
  5. Choose a trigger from the list by searching for the name of the product, and click Create.
  6. A new Playbook page will be displayed. Click on the module in the center of the page, then click on the Configure icon.
  7. On the right panel, click on the Configuration tab.
  8. Select an existing Trigger Configuration (from the account menu) or create a new one by clicking on + Create new configuration.
  9. Configure the Trigger based on the Actions Library (for instance, see here for AWS modules), then click Save.
  10. Click on Save at the top right of the playbook page.
  11. Activate the playbook by clicking on the "On / Off" toggle button at the top right corner of the page.

Important

At the end of the playbook, set up the action Push events to intake with a Sekoia.io API key and the intake key, from the intake previously created.

Raw Events Samples

In this section, you will find examples of raw logs as generated natively by the source. These examples are provided to help integrators understand the data format before ingestion into Sekoia.io. It is crucial for setting up the correct parsing stages and ensuring that all relevant information is captured.

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 Imperva WAF. 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-2018-13379 Fortinet Exploit

Detects the successful exploitation of the Fortinet FortiOS CVE-2018-13379. This CVE is one of the most exploited CVEs since 2018. It is exploited by APT threat actors as well as cybercriminals. The exploitation of this CVE lead an unauthenticated user to get full access to FortiOS system file through SSL VPN via specially crafted HTTP resource requests. The exploit read /dev/cmdb/sslvpn_websession file, that contains login and passwords in (clear/text). An HTTP response status code = 200, means the file was successfully accessed. This vulnerability affects FortiOS 5.6.3 to 5.6.7 and FortiOS 6.0.0 to 6.0.4.

CVE-2019-11510 Pulse Secure Exploit

Detects the successful exploitation of the Pulse Secure vulnerability CVE-2019-11510. This CVE is one of the most exploited CVEs since 2019. It is exploited by diverse threat actors, leading sometimes in ransomware deployement among these groups: Maze, Conti, Egregor, DoppelPaymer, NetWalker and REvil. But also APT actors such as APT29. The exploitation of this CVE allows a remote, unauthenticated attacker to compromise a vulnerable VPN server. The attacker may be able to gain access to all active users and their plain-text credentials. It may also be possible for the attacker to execute arbitrary commands on each VPN client as it successfully connects to the VPN server. The exploit reads /etc/passwd file to get access to login and passwords in (clear/text). An HTTP response status code = 200, means the file was successfully accessed. This vulnerability affects 8.1R15.1, 8.2 before 8.2R12.1, 8.3 before 8.3R7.1, and 9.0 before 9.0R3.4 products.

CVE-2019-2725 Oracle Weblogic Exploit

Detects the successful exploitation of a deserialization vulnerability in Oracle Weblogic Server, CVE-2019-2725. This vulnerability affects versions 10.X and 12.1.3 of WebLogic that have the components wls9_async_response.war and wls-wsat.war enabled. It is a remote code execution which can be exploited without authentication via HTTP. An HTTP response status code = 202, means the target is vulnerable, the analyst then has to look in depth to check if a webshell has been uploaded or something else has been done.

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.

CVE-2021-21985 VMware vCenter

The VMware vSphere Client (HTML5) contains a remote code execution vulnerability due to lack of input validation in the Virtual SAN Health Check plug-in which is enabled by default in vCenter Server. A malicious actor with network access to port 443 may exploit this issue to execute commands with unrestricted privileges on the underlying operating system that hosts vCenter Server. This affects VMware vCenter Server (7.0 before 7.0 U2b, 6.7 before 6.7 U3n and 6.5 before 6.5 U3p) and VMware Cloud Foundation (4.x before 4.2.1 and 3.x before 3.10.2.1).

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.

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.
