CSEC630 Lab 2

Leave a reply

Ok. The lab was pretty much what I expected.

Click this Panic button to reset everything. Go look at this pcap in Wireshark. Run this command in cmd.exe (and even walks the student through opening a term window by go to the start button, type cmd in the run box).

Run Snort with the test option on a pre-defined rule set using the pcap you looked at. Modify the same rule multiple times, enabling and disabling an alert each time. Run to see the difference.

Answer these 10 questions.

The last question was how to improve the class… I forgot to say use a Linux VM instead of a Windows VM. Since one of my answers did require Grep. Which means copy and paste from the VM lab to my box connected to the lab.

Automating OSINT Python Course

Leave a reply

A few months ago, a friend and co-worker asked if I had seen Automating OSINT. I hadn’t, so I went and checked it out and end up signed up for the free webinar. Turns out I had just missed the previous one by a few hours. And had some time to wait before the next one.

I’ve been wanting to expand beyond just bash scripting for most of my career. I tried learning Perl, and then I tried Python. The Google Python class, the MIT Python Class, Learn Python the Hardware, Think Python, Automate the Boring stuff with Python, and buying Python courses from Boing Boing. Problem is I never finished any of them. I think because I lose interest, and have other things to do.

Raspberry Pi WPA_Supplicant setup taking way longer than it should

Leave a reply

—- TL/DR —-
If you want to connect a raspberry pi to a hidden access point your wpa_supplicant.conf needs to have the following in the network statement.

Don’t put a ” or a ) in your ASCII PSK it causes problems. I couldn’t get it to work with the hex psk using wpa_passphrase but I broke the rules of troubleshooting making multiple changes at a time instead of one and resetting it.

—– End TL/DR —-

I got a new phone. Nexus 5x.  But this isn’t what this post is about. My SO got a new phone last August. It was an unplanned by after the last one went for a porta-john swim. Again. not what this is about.

A co-worker suggested setting up a NAS to back up the pictures to. Being a poor college student, yes still grad school isn’t cheap, that really isn’t an option. Then he said well if it’s just the phones, why not use one of your Raspberry Pis?

The problem is getting the wpa_suplicant.conf file talking. It has taken me 2 days. Mainly because I don’t mess with that file much.

it hated my passphrase because of the ” and the ) in the middle example:

I tried wpa_passphrase with the file, but it didn’t like that either. (although I kind of want to go back and test it again, in case I missed something.

Which I couldn’t find out until after I set the AP to broadcast. So after more digging I found that

scan_ssid=1 has to be in the config.

Sigh. This is taking way longer than need be, and I’d just wire it, but it’s going to not be near the cables, because of power.

Spending a weekend re-installing my firewall appliance was not my plan

So recently while trouble shooting that mail log in problem from my phone, I started going through the web interface on my pfSense box. While in the LAN interface, and it being 4am, I was like why is block RFC1918 for the Wan (which is on every interface tab), and block Bogons, not checked.

So I did what anyone half sleep deprived would do, I checked the boxes and hit apply.  Then I couldn’t get back in to the silly thing. Console wouldn’t work. I just got a blank screen, rebooting while consoled  in would go through the post and loading of BSD but after pfSense started, I didn’t get a menu.

Hey I know, I’m a Nix person, I’ll boot from the live image, go in to recovery find and turn off that setting, sync to the hard drive and reboot.

It’s all about the pcaps baby

Leave a reply

So my android phone as an interesting problem, granted it’s an S4, running not the latest build so I don’t know if that problem still exists. Apparently the way the default mail application is set up, it can’t sync the mailboxes unless the Sync button is turned on. But that doesn’t stop that the mail application from trying to sync on a schedule.

Oh look HTTPS

Leave a reply

Testing out Let’s Encrypt public beta. My thoughts so far:

90 days for the SSL certificate. Does that mean we’ll be seeing spammers setting these up to make their sites look more legit?

Mainly made for HTTPS on web servers. There is a walk through on making it work with email, using links, and some other dark Unix magic (what not everyone is running a linux mail server?). I saw a file for exchange but that’s not my cup of tea. It also brings up that whole 90 days thing again. So for now my mail server has something else.

So while the SSL Cert is good for 90 days, they tell you to update it every 60. Can’t wait to try that in 2 months. (that was sarcasm).

To be honest though, I do like the idea of Let’s Encrypt. I like that it has Debian love and script to make magic happen in the background. Less fiddling under the hood. I like that you can set up either Secure only (all HTTPS all the time) or HTTP and HTTPS. This site used to use a self signed cert for Administration, but now it’s all SSL.

Hopefully in the future we can get at least 365 day certs, more services covered, and most importantly MORE PEOPLE ENCRYPTING their web traffic.

New and Improved WiFi Intrusion Detection System. Pi 2.

Leave a reply

So my last post I was fighting the Raspberry Pi 2, with Kali Linux 2.0.1, when it came to starting kistmet_drone on boot. Ian had a work around, but it wasn’t what I wanted. I wanted the built in tools to do their job. Well it turns out it’s a SystemD problem. I spent probably about 12 hours bashing my head against it, making changes and trying things.

Finally, I got smart with my Google searching, and found a slightly better way, but still didn’t want to call an external shell script. Then I spent time smacking my head on the desk. SSHD works, and starts by systemd, why not look at it’s config. Seriously the better you are at something, the less you think of the simple answers that made you good to start with.

2 new lines. One made SystemD wait until after networking was up. The second was a strange sshd -D option. man ssh. Oh doesn’t run ssh as a daemon…

remove –daemonize from Kismet… It worked.

SO….

 

Now to get everything ready before I leave for GrrCon in 17 hours, I’ll be presenting Saturday last I heard.

More on moving WIDS to the Raspberry Pi 2.

Leave a reply

So I’m using the Raspberry Pi 2 and Kali 2 for this project so far. As I said last time, I had to expand the image to use the full disk. I have a script for that now. I was actually trying to script the whole deployment. These scrips can be found on my WIDS github repository. But fair warning they are still a work in process.
