THOR-Util with HTML Report Generation

by Florian RothJun 20, 2018

The new version of “thor-util” (used with THOR/SPARK) / “spark-core-util” (used with SPARK Core) support a feature that allows a user to convert any scanner log file into a convenient report.

Convert THOR / SPARK / SPARK Core scan logs into HTML reports
Convert a single text log file into an HTML report
Convert multiple log files (50 max.) in a directory into a single HTML report
Provide a file with filters to suppress false positives in the reports
Even LOKI logs can be converted (no support)
Hash values linked to Virustotal searches
IP values linked to VirusTotal searches
Header sections linked to elements via ankers

You can access this feature in the upcoming enterprise products (THOR 8.47.2 and SPARK 1.13) and the free product SPARK Core (SPARK Core 1.13).

The following screenshot shows a typical text log file. It can be processed in log analysis solutions but it is difficult to read for an analyst. Most analysts search these log files for “(Alert|Warning):” or use grep to get the most relevant messages.

Our tools “thor-util” and “spark-core-util” will help you with this task.

Generate an HTML report for a single log file

thor-util report --logfile PROMETHEUS_thor.log

Generate an HTML report for multiple log files

thor-util report --logdir ./logs

You can also provide a file with regular expressions that are applied during log parsing as filters to suppress false positives in the reports.

The new tools will be in all productive packages at the end of this week.
