Exploit target

An exploit target represents a vulnerability or a weakness in a software or hardware product or system, in a network, or in a configuration that enables a threat actor to use it as an entry point to access your assets and resources, and eventually to take control over them. Like a window that is left open upon leaving the house, it is a security hole in your ecosystem or infrastructure that malicious actors can leverage to get in and pursue their objectives.

Create an exploit target by selecting:

• In the side navigation bar + Create > Exploit target.

Or:

• (Requires Beta: Intelligence creation on the graph)

  In the top navigation bar of a graph, select + and then Exploit target to create a draft entity.

• Double-click to open the newly created draft entity to edit it.

Then, Configure this entity.
