.SYNOPSIS This cmdlet is used to authenticate to the Cybereason API. Once this is done a global $CybereasonSession variable is created that will be used for all other cmdlets in this module. .DESCRIPTION This cmdlet creates a $CybereasonSession variable that will be used with all the other cmdlets in this module to authenticate requests made to the Cybereason API. .PARAMETER Server This parameter defines the server IP address or domain name your Cybereason server is running on .PARAMETER Port This parameter is used to define the port your Cybereason server is on. This is usually 443 or 8443. The default value is 443. .PARAMETER Username This is the email address you use to sign into Cybereason .PARAMETER Passwd This is the password you use to sign into your Cybereason account. The session history gets cleared to attempt preventing the password from appearing in the session logs. This does not clear the events logs. I suggest only letting administrators view the PowerShell event logs. .PARAMETER Authenticator This parameter is for NON-API Cybereason users to authenticate to Cyberason using Two Factor Authentication (TFA). When used, the only cmdlet in this module that will work is Get-CybereasonThreatIntel .EXAMPLE Connect-CybereasonAPI -Server 123.45.67.78 -Port 8443 -Username api-user@cyberason.com -Passwd "Password123!" -ClearHistory # This example authenticates to the Cybereason API and creates a $CybereasonSession variable to be used by other cmdlets. This also clears the PowerShell command history of the current session as well as the HistorySavePath file value. .EXAMPLE Connect-CybereasonAPI -Server 123.45.67.78 -Port 443 -Username admin-user@cyberason.com -Passwd "Password123!" -Authenticator 123123 -ClearHistory # IMPORTANT: Only non-api users are able to use Two Factor Authentication (TFA). This prevents organization level cmdlets from working. Only Get-CybereasonThreatIntel works after authenticating with a non-API user .NOTES Author: Robert H.

Note that using the targetId parameter is supported only for processes (the KILL_PROCESS action) and files (the QUARANTINE_FILE or UNQUARANTINE_FILE action).

You can find this GUID for the quarantined file by running a query with the Quarantine File Element. .PARAMETER ActionType The remediation action to perform. Possible values include: KILL_PROCESS. Use this option to immediately stop the process associated with the root cause of the Malop. DELETE_REGISTRY_KEY. Use this option to remove any registry keys detected as malicious as part of the Malop. QUARANTINE_FILE. Use this option to quarantine the detected malicious file in a secure location. UNQUARANTINE_FILE. Use this option to enable the Cybereason platform to remove a file from quarantine. This option is available in version 20.1.120 and later. BLOCK_FILE. Use this to enable Application Control to block the file(s) associated with the Malop when it they are detected in the future. KILL_PREVENT_UNSUSPEND. Use this option to prevent detected ransomware from running on the machine. UNSUSPEND_PROCESS. Use this option to prevent a file associated with ransomware. ISOLATE_MACHINE: Use this option to isolate a specific machine. .EXAMPLE Invoke-RemediateItem -MalopID "11.2718161727221199870" -InitiatorUserName "admin@yourserver.com" -MachineID "-1632138521.1198775089551518743" -ActionType KILL_PROCESS # This example remediates a process by killing it after it was discovered by a Malop .EXAMPLE Invoke-RemediateItem -InitiatorUserName "admin@yourserver.com" -MachineID "-1632138521.1198775089551518743" -TargetID "-2095200899.6557717220054083334" -ActionType KILL_PROCESS # This example remediates a process that was not involved in a Malop .NOTES Author: Robert H.
