In my previous post, I went though the structure of the AppCompatCache and then parsed out the actual values found. I expect this to be the last part of this series and goes over some additional findings and thoughts. However, I'm working with Richard of 13Cubed on this,

I’m still digging into the values found in my previous post (AppCompatCache Deep Dive) and as part of that, wanted to see the actual values being flagged, not just Yes for 01 00 and No for everything else. This is a bit of a side quest into doing that,

Let’s set some background first. Back in Windows XP and prior, the mere existence of AppCompatCache (aka Shimcache) could be used to prove execution. A program wasn’t shimmed unless it was actually executed. This changed in Windows 7, 8, and 8.1 (presumably Vista as well, but nobody

I received a phishing message via SMS today directing me to hxxps://cutt[.]ly/WegUqPxy?Lgp=brg1CtzWGg. I haven't done a post in a while, and thought this might be interesting to examine. urlscan.io This is a great site for examine single page phishing or suspect sites.

The following are some notes and a bit of a guide regarding collecting memory and disk from Proxmox Virtual Environment (hereafter PVE). There doesn't seem to be nearly as much information regarding best practices and potential pitfalls as there is for Hyper-V or ESXi. However, with the growing

I'm trying to nail down the steps to build the Log2Timeline Plaso Windows executable. Part of this is to make it more accessible to the community (for example, Autopsy, which still uses a 2018 version). Part is to make my job faster and easier (rather than having to

I intended for this to at least be  a two part series, part 1 is here [https://nullsec.us/carving-for/]. 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'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&

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 users Someone on twitter [https://twitter.com/Rooster_75/status/1470746847790706698] 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

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

There is an often-referenced article here [https://www.deploymentresearch.com/psscriptpolicytest-script-gets-blocked-by-applocker-in-the-event-log-why-and-what-are-those-files/] 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

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 [https://threatpost.

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 [https://www.ericooi.com/zeekurity-zen-part-i-how-to-install-zeek-on-centos-8/] on Eric Ooi's page, quality stuff) and built

Plus CloudFlare and proper LetsEncrypt Certs I 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

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 [https://en.wikipedia.org/wiki/MrSID] "MrSID (pronounced Mister Sid)

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,

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

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

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

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 [https://twitter.com/hashtag/threerandomwords?src=hash&ref_src=twsrc%5Etfw]: memorable but not easy

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

Or "Microsoft SQL Express and the Truly Terrible, Just Awful, No Good Downloader" TL;DR up front. 1. 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 intercept 2. On your
