Callbacks exceeding this limit will be rejected. 12 | - ```limits.\*_validated=false``` means that the three following "**..._maxlen**" settings are ignored 13 | - Setting any of the ```..._maxlen``` settings to zero will disable that particular setting 14 | - ```limits.\*_diskused_percent``` sets the threshold for callback processing. Callbacks are rejected when disk usage exceeds the specified percentage 15 | - ```limits.\*_diskused_percent=0``` (zero) disables this setting 16 | - Valid values are 0-99 17 | 18 | Add a limit to the number of beacons allowed (spam protection). 19 | - ```limits.beacons_max``` is the maximum number of beacon allowed (default is *500*) 20 | - ```limits.beacons_max=0``` (zero) disables this setting 21 | 22 | Threshold rate for adding new beacons (spam protection). 23 | Add a limit to the number of new beacons added within a specified time period. 24 | When the limit is exceeded, disable accepting new beacons for the disable duration. 25 | - ```limits.beacon_rate_period``` milliseconds of the time period (default is *30000*) 26 | - ```limits.beacon_rate_period=0``` (zero) disables this setting 27 | - ```limits.beacon_rate_maxperperiod``` new beacons allowed during time period (default is *50*) 28 | - ```limits.beacon_rate_maxperperiod=0``` (zero) disables this setting 29 | - ```limits.beacon_rate_disableduration``` milliseconds to disable when threshold is exceeded (default is *600000*) 30 | - ```limits.beacon_rate_disableduration=0``` (zero) disables this setting 31 | 32 | Perform XSS Validation on select new beacon metadata (spam protection). 33 | - ```limits.beacons_xssvalidated``` (default is *true*) 34 | - ```limits.beacons_xssvalidated=false``` disables this setting 35 | 36 | Override the timestamp formatting pattern used for logfiles. 37 | - ```logfile.timestamp.pattern``` (default is *MM/dd HH:mm:ss zzz*) 38 | - ```logfile.timestamp.pattern=yyyy-MM-dd HH:mm:ss zzz``` 39 | 40 | Override the timezone used for the log files 41 | - ```logfile.timezone``` (default is *UTC*) 42 | - ```logfile.timezone=America/Los_Angeles``` 43 | 44 | ## Release Notes 45 | 46 | - The Cobalt Strike 4.4 release introduced an optional file, **TeamServer.prop**, that contains a number of parameters that can be used to customize the settings used to validate screenshot and keylog callback data. 47 | - The Cobalt Strike 4.7.1 release introduced new settings for the maximum number of beacons, thresholds for new beacons and beacon XSS validation. 48 | - The Cobalt Strike 4.11 release introduced new settings for timestamp formatting and timezone configuration. 49 | 50 | -------------------------------------------------------------------------------- /TeamServer.prop: -------------------------------------------------------------------------------- 1 | #Cobalt Strike Team Server Properties 2 | #July 16, 2024 3 | 4 | # ------------------------------------------------ 5 | # Validation for screenshot messages from beacons 6 | # ------------------------------------------------ 7 | # limits.screenshot_validated=true 8 | # limits.screenshot_data_maxlen=4194304 9 | # limits.screenshot_user_maxlen=1024 10 | # limits.screenshot_title_maxlen=1024 11 | 12 | # Stop writing screenshot data when Disk Usage reaches XX% 13 | # Example: Off 14 | # "limits.screenshot_diskused_percent=0" 15 | # Example: Stop writing screenshot data when Disk Usage reaches 95% 16 | # "limits.screenshot_diskused_percent=95" 17 | # Default: 18 | # limits.screenshot_diskused_percent=95 19 | 20 | # ------------------------------------------------ 21 | # Validation for keystroke messages from beacons 22 | # ------------------------------------------------ 23 | # limits.keystrokes_validated=true 24 | # limits.keystrokes_data_maxlen=8192 25 | # limits.keystrokes_user_maxlen=1024 26 | # limits.keystrokes_title_maxlen=1024 27 | 28 | # Stop writing keystroke data when Disk Usage reaches XX% 29 | # Example: Off 30 | # "limits.keystrokes_diskused_percent=0" 31 | # Example: Stop writing keystroke data when Disk Usage reaches 95% 32 | # "limits.keystrokes_diskused_percent=95" 33 | # Default: 34 | # limits.keystrokes_diskused_percent=95 35 | 36 | # ------------------------------------------------ 37 | # Add a limit to the number of beacons allowed (spam protection) 38 | # Setting the value to 0 (or less) will disable this function. 39 | # limits.beacons_max -
