GrokEVT is a collection of scripts built for reading Microsoft Windows NT/2000/XP/2003 event log files. Currently the scripts work together on one or more mounted Microsoft Windows partitions to extract all information needed (registry entries, message templates, and log files) to convert the logs to a human-readable format. This program is useful in forensics investigations.
grokevt-addlog
A tool for adding a raw event log to an existing GrokEVT database.
root@kali:~# grokevt-addlog -h
USAGE:
/usr/bin/grokevt-addlog <DATABASE_DIR> <EVT_FILE> <NEW_TYPE> <BASE_TYPE>
This script takes a raw Windows event log and adds it to a
previously built database generated by grokevt-builddb.
See the man page for more details.
grokevt-builddb
Builds a database tree based on a single windows system for the purpose of event log conversion.
root@kali:~# grokevt-builddb -h
USAGE:
grokevt-builddb [-v] [-c CSID] <CONFIG_PROFILE> <OUTPUT_DIR>
grokevt-builddb builds a database tree based on a
single windows system for the purpose of event log
conversion. Please see the man page for more
information.
ERROR: Requires at least 2 arguments.
grokevt-dumpmsgs
A tool for dumping the contents of message databases built previously by grokevt-ripdll(1).

NAME
grokevt-dumpmsgs - A tool for dumping the contents of message databases
built previously by grokevt-ripdll(1).
SYNOPSIS
grokevt-dumpmsgs message-db1 [message-db2 ...]
DESCRIPTION
grokevt-dumpmsgs takes one or more message databases previously built with
grokevt-ripdll(1) and prints out all entries to stdout. This is mainly a
debugging tool, but may be useful for analyzing the message contents of PE
files while developing other applications.
ARGUMENTS
grokevt-dumpmsgs uses the following arguments:
message-dbN
If multiple message databases are supplied, entries of all data-
bases are printed to stdout in the order they are provided.
OUTOUT
grokevt-dumpmsgs prints each database entry out on a single line, in two
comma-separated columns. The first column is the message ID, which is in
the format:
XXXX-YYYYYYYY
Here, XXXX represents the message's language code, and the YYYYYYYY repre-
sents the message's relative virtual address (RVA) within the message
block of the PE file. The second column contains the message itself. Mes-
sages containing special characters (such as newlines or commas) are en-
coded in the same manner that grokevt-parselog(1) encodes them ("%XX"
where XX is the hexadecimal value of the character).
BUGS
Probably several. This particular script has not been extensively tested.
