"MITRE ATT&CK technique T1087 articulates that adversaries may attempt to get a listing of accounts on a system or within an environment which can help them determine which accounts can aid in follow-on behavior. Therefore, the AccountDiscovery PBA is relevant to it which will enable the ATT&CK technique and show it in ATT&CK report."
"text": "Read our [documentation](https://www.guardicore.com/infectionmonkey/docs/development/adding-post-breach-actions/) about adding a new PBA.\n\nAfter that we want you to add the AccountDiscovery PBA. The commands that add users for Windows and Linux can be retrieved from \\`get\\_commands\\_to\\_discover\\_accounts\\` — make sure you see how to use this function correctly.\n\nNote that the PBA should impact the T1087 MITRE technique as well.\n\n**Manual test to confirm**\n--------------------------\n\n1. Run the Monkey Island.\n \n2. Make sure your new PBA is enabled by default in the config. For this test, disable network scanning, exploiting, and all other PBAs.\n \n3. Run the Monkey Agent.\n \n4. See the PBA in the security report and in the MITRE report under the relevant technique."
"text": "Many PBAs use shell commands or scripts — see `Timestomping` and `AccountDiscovery`.\n\nOn the other hand, some are less straightforward. You can override functions and implement new classes depending on what is required, to implement complicated PBAs — see `SignedScriptProxyExecution` and `ModifyShellStartupFiles`. \n \n\nThis PBA, along with the others, will run on a system after it has been breached. The purpose of this code is to test whether target systems allow attackers to gather details about all the user accounts that are present on a system or in an environment."
