Seatbelt
Seatbelt is a C# project that performs a number of security oriented host-survey "safety checks" relevant from both offensive and defensive security perspectives.
@andrewchiles' HostEnum.ps1 script and @tifkin_'s Get-HostProfile.ps1 provided inspiration for many of the artifacts to collect.
@harmj0y is the primary author of this implementation.
Seatbelt is licensed under the BSD 3-Clause license.

AntiVirusWMI - Registered antivirus (via WMI)
InterestingProcesses - "Interesting" processes- defensive products and admin tools
RegistryAutoRuns - Registry autoruns
RegistryAutoLogon - Registry autologon information
DNSCache - DNS cache entries (via WMI)
ARPTable - Lists the current ARP table and adapter information (equivalent to arp -a)
AllTcpConnections - Lists current TCP connections and associated processes
AllUdpConnections - Lists current UDP connections and associated processes
NonstandardProcesses - Running processeswith file info company names that don't contain 'Microsoft'
* If the user is in high integrity, the following additional actions are run:
SysmonConfig - Sysmon configuration from the registry
SeatBelt.exe user collects the following user data:
SavedRDPConnections - Saved RDP connections
TriageIE - Internet Explorer bookmarks and history (last 7 days)
DumpVault - Dump saved credentials in Windows Vault (i.e. logins from Internet Explorer and Edge), from SharpWeb
RecentRunCommands - Recent "run" commands
PuttySessions - Interesting settings from any saved Putty configurations
PuttySSHHostKeys - Saved putty SSH host keys
CloudCreds - AWS/Google/Azure cloud credential files (SharpCloud)
RecentFiles - Parsed "recent files" shortcuts (last 7 days)
MasterKeys - List DPAPI master keys
CredFiles - List Windows credential DPAPI blobs
RDCManFiles - List Windows Remote Desktop Connection Manager settings files
* If the user is in high integrity, this data is collected for ALL users instead of just the current user
Non-default collection options:
CurrentDomainGroups - The current user's local and domain groups
Patches - Installed patches via WMI (takes a bit on some systems)
LogonSessions - User logon session data
KerberosTGTData - ALL TEH TGTZ!
InterestingFiles - "Interesting" files matching various patterns in the user's folder
IETabs - Open Internet Explorer tabs
TriageChrome - Chrome bookmarks and history
TriageFirefox - Firefox history (no bookmarks)
RecycleBin - Items in the Recycle Bin deleted in the last 30 days - only works from a user context!
4624Events - 4624 logon events from the security event log
4648Events - 4648 explicit logon events from the security event log
KerberosTickets - List Kerberos tickets. If elevated, grouped by all logon sessions.
SeatBelt.exe all will run ALL enumeration checks, can be combined with full.
SeatBelt.exe [CheckName] full will prevent any filtering and will return complete results.
SeatBelt.exe [CheckName] [CheckName2] ... will run one or more specified checks only (case-sensitive naming!)
Compile Instructions
We are not planning on releasing binaries for Seatbelt, so you will have to compile yourself :)
Seatbelt has been built against .NET 3.5 and is compatible with Visual Studio 2015 Community Edition. Simply open up the project .sln, choose "release", and build.
