  • DNS Benchmark v2 is Finished and Available!
    Guest:
    That's right. It took an entire year, but the result far more accurate and feature laden than we originally planned. The world now has a universal, multi-protocol, super-accurate, DNS resolver performance-measuring tool. This major second version is not free. But the deal is, purchase it once for $9.95 and you own it — and it's entire future — without ever being asked to pay anything more. For an overview list of features and more, please see The DNS Benchmark page at GRC. If you decide to make it your own, thanks in advance. It's a piece of work I'm proud to offer for sale. And if you should have any questions, many of the people who have been using and testing it throughout the past year often hang out here.
    /Steve.

  • BootAble – FreeDOS boot testing freeware

    To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.

    GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.

    The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.

    You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

OpenCanary Logging question

I have OpenCanary systems running, the most interesting of which is in Oracle Cloud.

The logs create webhooks with JSON content:

Code:

The Regex for each field I want to capture:
Code: 
^.*dst_port": (.+?), ".*$
^.*local_time": "(.+?)\..*$
^.*PASSWORD": "(.+?)".*$
^.*USERNAME": "(.+?)".*$
^.*src_host": "(.+?)".*$

What I am looking for is a free (it’s limited volume) analysis with some pie charts that I can embed into a webpage. I managed to get this from Loggly See image). Does anyone have any ideas as to a solution?

Thanks!

Some observations:
1. I am still with Loggly, the free tier gives me an overview and allows me to search the logs. I get 535 connection attempts per hour parsing a username to my OpenCanary
2. I've updated a guide I wrote as I solved some SMB logging issues that were causing a blind spot
3. The blind spot and my encouraging native with my smb.conf allowing writing of files resulted in some malware samples being stored with me :rolleyes::D I've turned read-only back on and put some canary tokens up there.....
