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

XMRIG, KINSING, MIRAI etc. are being deployed by threat actors after exploiting this vulnerability.

Cyber Essentials – Out of the Box

New machines means it’s easy right?

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!

Adding a removing the mark of the web via…

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)

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!

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 Events vs Incident vs Attack

Cyber Events

Yesterday I was asked about “attack volumes” I see in the PwnDefend HoneyNet and it reminded me about what people think an “ATTACK” is and therefore spring my brain into thinking about how we as an industry communicate. Far too often I see “number of ATTACKS” being used my marketing/sales etc. where the numbers are simply ridiculous and not reflective of how offensive cyber operations actually work.

Let’s look at some examples:

“Gov. Greg Abbott warns Texas agencies seeing 10,000 attempted cyber attacks per minute from Iran”

CISO Tabletop Scenario Intro

I thought it would be fun to explore what people do with regards to Cyber Securityleadeship, budgets, contraints and realities of business change. So here’s a blog post to supliment my thread on twitter:

please note: the list below is based on experiance, it’s also a list I made whilst drinking about half a cup of tea so it’s not complete or “the answer” it’s just some observations about an approach I advocate.

Why do “we” suck so badly at digital security…

Everything is fine until it’s not

I’ve been travelling to different organisations and visiting different networks for a while and whilst each organisation is unique (they really are) their operating models, technology challenges and weak security postures generally aren’t as unique as the organisational itself.

One thing that does spring to mind however is that there is a massively common pattern we find with organisations.

Those that invest well have better postures, better technology experiences and an improved security posture.
Those that don’t historically invest well, well they have quite the opposite:
- They don’t train staff
- They have very weak postures
- They carry an extraordinary volume of business risk

One thing that is common though, is that all of this tends to link to financial investments, so executives and boards usually have some idea if they are spending or not in this space, what they commonly don’t have a good view on is they getting what they “thought they were buying”. Sadly, too often what they assumed was “in the box” with the “IT provision” with regards to quality and cyber security just simply isn’t the case. Everything is fine, until you look… then it’s less than fine! So, what can we do about it?
