I intended for this to at least be  a two part series, part 1 is here. I'm not sure yet if this will be the end of it or not. I did successfully recover some information from a deleted snapshot, so success there. However, I still don't feel like this

I'm actually having some problems getting the final results in a lab, so I'm going to go through the tool and lab setup first. Hopefully this will encourage someone to point out what I'm doing wrong or a lab setup that will work. I'm using WSL 2, Ubuntu 22.04,

When people ask what their baseline configuration should be, in terms of logging, I feel like it often gets answered with general advice regarding knowing your environment, having different configurations for file servers vs domain controllers, etc. This is true advice, but not particularly helpful. You might not know your

For average/home usersSomeone on twitter asked two questions that I thought might be valuable for this article, paraphrasing: Can someone explain the Log4j vulnerability in non-IT terms, and is there any mitigation my level as average mere mortal?1) A log component can ask external systems questions. The answers

If you haven't watched it already, there's some great YouTube videos by Richard Davis of 13cubed that I suggest you start with. If you're just looking for the commands to run, scroll towards the bottom. There are a LOT of advanced options that could be used, this is just my

There is an often-referenced article here that lays out what these files look like, what they do, and where they originate. From the perspective of trying to identify them however, it was a bit out of date, and nobody really goes over everything that these files can contain. I'm not

I have, for a long time, been watching my logs for unusually long command line artifacts. Something suspicious doesn't have to be long, but except for a few well-known and easily ignored applications, most long command lines are suspicious. For example, imagine you came across this in your logs: Suspicious,

I'm sure the first thing you're asking yourself is why. Stubbornness is your answer. I was playing with Zeek at home (if you want to get started, check out Zeekurity Zen on Eric Ooi's page, quality stuff) and built everything on Ubuntu 20.04. I decided I wanted to add

Plus CloudFlare and proper LetsEncrypt CertsI got bored and decided to play with a cloud-hosted Foundry VTT server. They have some great guides for getting started with some of these. I could get a little more bang for my buck though if I went with Amazon Lightsail. Lightsail is basically

Just notes because every forum post I came across for this was 10 years old, and all the references and links were out of date. Once you find the files, there's nothing difficult here. From the Wiki "MrSID (pronounced Mister Sid) is an acronym that stands for multiresolution seamless image

I've spent some time searching for an additional IR illuminator to supplement my security cameras. For those of you not familiar with what these are, the IR lights (or near-infrared, 850nm) on your camera are what allows it to see in the dark. Most cameras have decent lights, especially for

Very quick post, mostly notes for myself. When using Volatility 3 you might noticed that some plugins cannot be loaded # ./vol.py -h [...] The following plugins could not be loaded (use -vv to see why): volatility.plugins.windows.cachedump, volatility.plugins.windows.callbacks, volatility.plugins.windows.hashdump, volatility.plugins.windows.

It's been a while since I have posted anything, and today I ran across a Tweet and had a conversation that I thought would make a perfect subject. It begins with "A mini thread: I periodically see folks suggest that to prevent weak passwords you should dump AD and compare

Updated: 29 May 2020 @ 13:25 UTC - Added additional Pipal analysis.This is the first of my "Password Analysis" posts that I've published, but the second one I've written. I started with 000webhost, but had not completed that when this breach hit. This one is more relevant at the

Update 27 May 2020 @ 13:17 UTC - See bottomUpdate 27 May 2020 @ 19:48 UTC - Related post analyzing passwords in use: https://nullsec.us/livejournal-password-analysis/ There's a lot of talk about the LiveJournal breach going on right now. I wasn't too surprised to receive the HIBP email, I

I'm a huge fan of https://makemeapassword.ligos.net/generate/readablepassphrase, and regularly advise people to use it when generating passwords that need to be memorized or typed frequently. However, there's been numerous times people have expressed concerns that they're effectively generating passwords on someone else's computer. This is (typically)

I wanted to address a tweet posted today by the UK's National Cyber Security Centre advising people to use three random words as a passphrase. When choosing your password, use #threerandomwords: memorable but not easy to guess, a good compromise between protection and usability https://t.co/6pEf004ohb pic.twitter.

There's a lot of useless posts going around about this right now. I hope mine is a little more useful since most of these don't mention if this is being exploited in the wild. TL;DR - no, it isn't, no need to panic right now. Keep an eye on

Or "Microsoft SQL Express and the Truly Terrible, Just Awful, No Good Downloader"TL;DR up front. On a secondary machine/VM, setup a Burp proxy to use the non-localhost interface (192.168.1.230 in my case) as a proxy. Turn off interceptOn your Windows system, set Internet Properties

Update: This event appears for both binaries and websites in build 1809 and 1909, but only for binaries in 1903 (not web). So if you're looking for this event and not finding it, that may be why. I have not confirmed this myself, so if someone else comes across this,

There's really nothing special here except a mildly updated example of the code found here: https://docs.splunk.com/Documentation/Splunk/8.0.1/RESTTUT/RESTsearches#Python_example Basically, updated to python3 due to the impending end-of-life (print() adjustment, and urlencode had changed in Python3). While I was at it,

Wireshark on Red Hat Enterprise Linux is, for some reason, about a decade out of date. The current version available via yum install is 1.10.14. This version was released in June 2013, and reached end of life in June 2015. Now, RHEL might be back-porting security patches (I'm

From time to time I need to audit a large number of devices for default credentials. I typically use Metasploits http_login module for this. You can pass it a file of rhosts with something like set rhosts file://root/hosts.txt and have it check numerous systems quickly. However,

I thought this tweet might make a good blog post. I'm sure everyone in infosec will have their own answers, and all will be, generically, correct. Most of what I've seen is disagreements over one or two of the points, or how to remedy a point, or the implementation. What
