7MS #270: IDS on a Budget - Part 4

7MS #270: IDS on a Budget - Part 4

I spent a bunch of time with Security Onion the last couple week's and have been lovin' it! I ran the install, took all the defaults, ran the updates, and pretty much just let it burn in on my prod (home) environment.

After a few days, I went back to check the Security Onion dashboard to check the alerts. There was a bunch of benign stuff (computers pinging each other, Dropbox broadcasting to the network) but also a couple interesting finds - SO caught one of my VMs downloading (intentionally) Invoke-Mimikatz. The dashboard allows you to see transcripts of file downloads like this, as well as a tool called Network Miner to extract a copy of the downloaded file for further analysis.

One thing the SO didn't pick up on was the DNS-based C2 tunnel I setup on a test victim client. However, it turns out RITA works great for exactly this type of analysis - it reported the huge number of DNS requests from my victim client to the C2 server. Very helpful info for an incident response situation!

7MS #122: OFFTOPIC-An Apology to Elephants

7MS #122: OFFTOPIC-An Apology to Elephants

Preview76 wordsThis episode is about a documentary called An Apology to Elephants. It's all about the treatment (or mistreatment) of elephants, and the main message of the movie is, "Please don't go to the circus when it's in town, because you're supporting elephant abuse." Even if that message was a little heavy handed, I certainly will pass on tickets next time a circus act comes through town. You can subscribe to the 7 Minute Security podcast here.

7MS #121: Migrating from Tumblr to Ghost-Part 2

7MS #121: Migrating from Tumblr to Ghost-Part 2

Part 2 concludes my journey in moving 7ms.us from Tumblr to a Digital Ocean droplet running Ghost. Here are the key resources mentioned during the podcast: How to run multiple Ghost blogs on one DI VPS. The key takeaway here was that I had to upgrade to the $10 droplet (I did a "flexible" resize to add more proc/memory) and then the second instance of Ghost installed fine. Turning on CloudFlare SSL was easy. I chose flexible SSL since I wasn't using a "real" cert. I also wrote a rule to force HTTPs for all connections. And, just for grins, I turned on DNSSEC. Because...why not? :-) I picked a strong root password for my DI droplet, but I still don't like the idea of IPs banging on that connection all day and night. I followed this article on installing Fail2Ban to prevent my SSH login from being abused. There are a few IPs that I want to perma-ban, so I'm going to look throughthis article and this one which looks a tad easier. You can subscribe to the 7 Minute Security podcast here.
