|Network connections | This folder contains a set of data points related to the connectivity information which can help in identifying connectivity to suspicious URLs, attacker’s command and control (C&C) infrastructure, any lateral movement, or remote connections.</br></br> - ActiveNetworkConnections.txt – Displays protocol statistics and current TCP/IP network connections. Provides the ability to look for suspicious connectivity made by a process. </br></br> - Arp.txt – Displays the current address resolution protocol (ARP) cache tables for all interfaces. </br></br> ARP cache can reveal additional hosts on a network that have been compromised or suspicious systems on the network that night have been used to run an internal attack.</br></br> - Dnscache.txt - Displays the contents of the DNS client resolver cache, which includes both entries preloaded from the local Hosts file and any recently obtained resource records for name queries resolved by the computer. This can help in identifying suspicious connections. </br></br> - Ipconfig.txt – Displays the full TCP/IP configuration for all adapters. Adapters can represent physical interfaces, such as installed network adapters, or logical interfaces, such as dial-up connections. |
| Prefetch files| Windows Prefetch files are designed to speed up the application startup process. It can be used to track all the files recently used in the system and find traces for applications that might have been deleted but can still be found in the prefetch file list. </br></br> - Prefetch folder – Contains a copy of the prefetch files from `%SystemRoot%\Prefetch`. NOTE: It is suggested to download a prefetch file viewer to view the prefetch files. </br></br> - PrefetchFilesList.txt – Contains the list of all the copied files which can be used to track if there were any copy failures to the prefetch folder. |
| Processes| Contains a .CSV file listing the running processes which provides the ability to identify current processes running on the machine. This can be useful when identifying a suspicious process and its state. |
| Scheduled tasks| Contains a .CSV file listing the scheduled tasks which can be used to identify routines performed automatically on a chosen machine to look for suspicious code which was set to run automatically. |
| Security event log| Contains the security event log which contains records of login or logout activity, or other security-related events specified by the system's audit policy. </br></br>NOTE: Open the event log file using Event viewer. |
| Services | Contains the services.txt file which lists services and their states. |
| Windows Server Message Block (SMB) sessions | Lists shared access to files, printers, and serial ports and miscellaneous communications between nodes on a network. This can help identify data exfiltration or lateral movement. </br></br> Contains files for SMBInboundSessions and SMBOutboundSession. </br></br> NOTE: If the file contains the following message: “ERROR: The system was unable to find the specified registry key or value.”, it means that there were no SMB sessions of this type (inbound or outbound). |
| Temp Directories | Contains a set of text files that lists the files located in %Temp% for every user in the system. </br></br> This can help to track suspicious files that an attacker may have dropped on the system. </br></br> NOTE: If the file contains the following message: “The system cannot find the path specified”, it means that there is no temp directory for this user, and might be because the user didn’t log in to the system. |
| Users and Groups | Provides a list of files that each represent a group and its members. |
| CollectionSummaryReport.xls | This file is a summary of the investigation package collection, it contains the list of data points, the command used to extract the data, the execution status, and the error code in case of failure. You can use this report to track if the package includes all the expected data and identify if there were any errors. |
| Scheduled tasks| Contains a .CSV file listing the scheduled tasks which can be used to identify routines performed automatically on a chosen machine to look for suspicious code which was set to run automatically. |
