Ten years ago, after it became clear to almost everyone that all our online activity was being tracked and stored, I wrote a blog post about simple steps a person could take to improve their privacy online. Essentially, it contains a few recommendations that everyone could follow to reduce their fingerprint without much effort. It […]

Two years ago, I made a small tool on top of Cloudflare’s Workers to generate a single feed by taking input from multiple RSS sources, a kind of aggregator or planet software as it was usually known a few years ago. You can read more about it here and here. This is a basic tool […]
At the start of last week, we received great news regarding new improvements to a very popular security app, “Google Authenticator”. A feature it was lacking for a long time was finally implemented, “cloud backups”. However, after a few days, the security community realized the new feature wasn’t as good as everybody was assuming. It […]
Last year, I built a small tool to detect inline styles and scripts in a given webpage/document and then calculate their hashes. It can be useful for someone trying to write a strict “Content-Security-Policy” (CSP) for pre-built websites. I described the reasoning at the time in this blog post. Today, I’m writing to announce that […]
Last week, an article was published with some interesting numbers about the security of PostgreSQL servers publicly exposed to the internet (You can find it here). But more than the numbers, what really caught my attention was the fact that most clients and libraries used to access and interact with the databases have insecure defaults: […]
It already starts tomorrow… the next edition of “Hacktoberfest”. For those who don’t know, it basically is an initiative that incentivizes participants to contribute to open-source software. During the month of October, those who do 4 contributions or more, can either receive a t-shirt or opt for a tree to be planted in their name. […]
A few years ago I built a small application to test Django’s websocket support through django-channels. It basically displayed on a web page in real time all the requests made to a given endpoint (you could generate multiple of them) without storing anything. It was fun and it was very useful to quickly debug stuff […]
In a previous blog post published earlier this year I explored some security considerations of the well known “clipboard” functionality that most operating systems provide. Long story short, in my opinion there is a lot more that could be done to protect the users (and their sensitive data) from many attacks that use of clipboard […]
Django management commands can be very helpful while developing your application or website, we are very used to runserver, makemigrations, migrate, shell and others. Third party packages often provide extra commands and you can easily add new commands to your own apps. Today lets take a look at some less known and yet very useful […]
Content-Security-Policy (CSP) is an important mechanism in today’s web security arsenal. Is a way of defending against Cross-Site Scripting and other attacks. It isn’t hard to get started with or to put in place in order to secure your website or web application (I did that exercise in a previous post). However when the systems […]
