The cost of resetting a password

If someone asked you how much the cost of a task is, I bet you would struggle to given them an accurate response, the default position of most people is to underestimate a cost of doing something (but estimation science show’s us that it tends to vary based on role e.g. project managers are risk averse, engineers think they can solve things faster than they can and executives often just want it to be cheaper for the sake of it being cheaper – Parkinsons Squeeze I think that is called)

Years ago I stared looking at total cost of ownership (TCO) and Return on Investment modelling (I mean a lot of years ago….) and I’ve created a range of models for organisations for:

Fortiweb – CVE-2025-58034

‘CVE-2025-58034 is an OS command injection vulnerability (CWE-78) in Fortinet FortiWeb, allowing an authenticated attacker to execute unauthorized code on the system through crafted HTTP requests or CLI commands. It affects versions including FortiWeb 8.0.0-8.0.1, 7.6.0-7.6.5, 7.4.0-7.4.10, 7.2.0-7.2.11, and 7.0.0-7.0.11. The vulnerability has a CVSSv3 score of 6.7 (medium severity) and has been observed exploited in the wild, prompting its addition to CISA’s Known Exploited Vulnerabilities catalog.’

Another day another exploit in the wild it seems! (ok I’m a bit slow to this one). Using Defused Cyber’s Honeypots we have another packet to analyse:

Analysing 1 Million Honeypot events with Defused Cyber Deception

A common perimeter firewall in organisations is the CISCO ASA. Back when I started in the industry we used to have CISCO PIX firewalls, the ASA was the next generation of these! Why is this important? Well its important to understand how common threat actors work, you will see from a while ago I wrote a review of the manual 2.0 by Bassterlord (a known cybercriminal), this is to help understand how attackers work, what real world cybercrime looks like so that we can enable people to help defend against these threats.

Detecting ‘Dark Tunnels’ with Microsoft Defender using KQL

Detecting ‘Dark Tunnels’ is an important element to corporate security, much like detecting unauthorised RMM usage. But what is a dark tunnel?

according to GROK:

A dark tunnel (sometimes called a “dark pool tunnel” or simply a secure reverse tunnel in networking contexts) refers to a type of secure, outbound-only tunneling technology that allows private access to internal services, devices, or networks without exposing them to the public internet. The “dark” aspect emphasizes that the tunnel is hidden or invisible from external scanners—there’s no inbound port forwarding, firewall holes, or public IP exposure required. Instead, it relies on encrypted outbound connections from the internal resource to a cloud-based relay or peer-to-peer mesh, enabling zero-trust access (e.g., via authentication tokens or keys).
This approach is popular in DevOps, IoT, remote work, and cybersecurity for bridging on-premises or edge devices to the cloud securely, often bypassing NAT traversal issues or legacy VPN complexities.

Ransomware kill chains are boring.. will we ever learn?

Are we stuck in a cyber world that never learns? are we doomed to suffer the same fate over and over again? Well, not if you take action, you can totally prevent events like this!

This is a fast post using an LLM to analyse the Capita redacted ICO report. Hopefully it will help people think about things and take the lessons and apply them in their own organisations.

A threat to sanity – Cyber Myth: Juice Jacking

“Juice jacking” has become a modern cybersecurity myth — a catchy scare story built on a long-patched Android debugging issue and fueled by viral fear rather than facts. Despite years of warnings, there are no confirmed cases of real-world juice jacking attacks; the cost, effort, and low reward make it an impractical method for criminals. Yet the myth persists because it’s vivid, simple, and scary — everything our brains latch onto. The real danger is not the USB port at the airport, but the distraction such myths create. When people focus on imaginary threats, they waste precious attention that should go toward genuine risks like weak passwords, missing MFA, unpatched systems, and poor backups. So let’s take a bit of a deeper dive into this subject, because by it’s important to understand what to, and what not to focus on in my experience!

‘Secure’ Firewall backups, until they are not!

Firewalls are often both a defended gate but also the front door to access corporate network. That is all lovely until it’s not! You see so many corporate network intrusion incidents occur from threat actors simply logging into the VPN (due to lack of VPN), and then we have the software vulnerabilities where they shell their way in, but did you think that another way could be from stealing all the backups from a ‘security’ provider? Well now you might! There’s been bit of an incident (one that started as it’s only 5% of customers but actually it was 100% of customers who used the backup feature! YIKES), but before that let’s look at the typical landscape!

Breaching WPA2 PSK Wireless Networks

This weekend I was running a workshop with my awesome friend James, where we were discussing the realities of wireless network security, man in the middle attacks and what we have found in the field, both from an offensive perspective and as corporate network defenders. As with all things in life, sometime reality doesn’t work quite as well as a demo! So I’ve done a quick thread on twitter showing the kill chain an adversary can deploy when attacking WPA2 PSK (without PMF enforced) networks. This is written as a twitter thread so bear with the style!
