Ancient “AI” in the Age of Advanced Adversaries

There has been a lot that’s being said about the use of AI in Cyber Security. This is for good reasons – people have said here and folks in information security (as we have called “cyber security” for decades now) have experienced first-hand. It’s only natural that already stretched InfoSec teams look at AI as […]

Machine Learning Security in the age of Supply Chain Attacks

As can be seen from the recent “xz attack” discovery that there nation states have realized that this is likely the “best” vector to impact large-scale systems in big organizations. With the cloud computing providers being the “source of computing” for most large corporations today, we should anticipate that a larger portion of the attacks […]

Security Considerations in Blue-Green Deployments

tl,dr; Blue-Green deployments for critical uptime applications is a strong deployment strategy but if a deployment fixes critical security issues be sure that the definition of “deployment complete” is decommissioning of the “blue” environment and not just deployment of “green” successfully. Organizations have gotten used to following Continuous Integration/Continuous Deployment (CI/CD) for…

Security Considerations in use of AI/ML

The world of Artificial Intelligence (AI) seems to be exploding with the release of ChatGPT. But as soon as the the chat bot came into the hands of public people started finding self-sabotaging queries at worst (exploitable issues) and some weird interactions whereby people could write malware that could stay undetected by Endpoint Detection and […]

What to do when things go wrong?

I blogged earlier about blameless post-mortems and how one gets to a point that they are able to do blameless post-mortems – by having an operational rigor and observability. This is more of a lessons learnt post about what do you do and what you don’t when things go wrong? Focusing on the Who? A […]

The historical evolution of Cross-Site Request Forgery

Having been in application security for more than 2 decades now and officially completing my 18th year now of being meaningfully employed in that space there is just a lot of crud that I have gathered in my brain. Most of that is history of how things came about to be. That stuff is likely […]

Application Security and the Incident Response Process

Application or software security is a field of infinite complexity. All of us know that where there is complexity, security issues lurk around in those dark corners. This post is about my ramblings on how I believe Application Security and Incident Response need to come together to handle incidents. As usual, I make references to […]

A brief history of SSRF

Server-Side Request Forgery is a security issue in applications where an attacker is able to get a server to send some type of a request (these days mostly HTTP/s requests) that the server should not be able to send. This issue is the classic abuse of trust vulnerability – the server tends to sit in […]

Filing Tax Assessment Appeal in Jersey City

In this post, I will cover a how to for filing a resident’s tax appeal. It’s quite simple. This is not meant to cover all special situations but should cover simple situations if you live in a condo in Jersey City for example. For other situations, review the handbook listed below. Most importantly – this […]

Pcaprub installation on Win 10 x64

If you encounter the following error, the issue is pcaprub uses a hardcoded path for Winpcap. I downloaded winpcap v4.1.3 and downloaded the dev kit for Winpcap and put it in c:\WpdPack. Additionally, since I use an x64 machine I had to copy the file C:\WpdPack\Lib\x64\*.lib into C:\WpdPack\Lib and then the compilation worked. You need […]
