Passive Port Scanners & Internet Asset Discovery Platforms

Useful for a range of defensive and offensive purposes, internet asset search platforms enable a range of activities from:

Research & Trend Analysis
Vulnerability Hunting
Attack Surface Mapping
OSINT

Each has its own interfaces, features, dataset sand styles.

I’ve put together a list of the most popular, there may be more that I haven’t listed.

CVE-2022-26134 – Confluence Zero Day RCE

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

Cyber Essentials Readiness

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+.

Wireguard Client for Linux on KALI

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!

Myth: you must be a “techie” to lead in the CYBERS

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.

Introduction

I am sitting here, and I need another cup of tea, but I thought I’d start to have a think about what common “CYBER GANGS” look like. This isn’t criminal or non-criminal. But you know there’s some commonality between both. I thought this was fun little thinking exercise to show the duality of life, what digital worlds look like but also to give a glimpse into the mysteryious (its not!) world of cyberz (including crime!)

The Director of GCHQ speaks at CyberUK 2022

Sir Jeremy Fleming was speaking at CyberUK, the UK’s flagship cyber security conference this week.

The full presentation is here but I’ve picked out some key highlights.

“Of course, we can count ourselves lucky compared to those caught up in wars, but we are also seeing a heightened cyber risk. Cyber criminals are consistently evolving their tactics; the lines are blurring with hostile state activity and ransomware remains a real threat.”

“Cyber clearly matters to everyone.”

“At the global level, the UK has developed as a cyber power. Alongside the more traditional forms of diplomacy and statecraft, cyber now plays a vital role in our national security and prosperity.”

CYBER CYBER CYBER – What cyber means for the…

I’m sitting here drinking a cup of tea and thought I’d jot down some of the things I tend to think about. I figured this might help people consider aspects of “cyber” that they might not have considered before.
