Phishing campaigns are standard, but they are typically poorly done and low-effort. But, sometimes, we catch a good one. This reports an analysis carried over one of those shady emails.
Today, 1 April of 2022, I have successfully defended my PhD thesis work on Software Engineering and Internet-of-Things entitled “Increasing the Dependability of Internet-of-Things Systems in the context of End-User Development Environments”. Here follows the abstract.
Now that I’ve finally delivered my PhD thesis (awaiting public defense), and after sharing for more than 3 years my tools, strategies, and tips for surviving in the academic world by word of mouth, I have finally got the time — and energy — to put this in a written form.
Radio communications always had my curiosity, but little to no focus. Recently I bought a Software-defined Radio (SDR) and started doing some experiments… and now I’m building my own antennas for receiving satellite images. These are some field notes on radio waves and others.
Yet another month, yet another ØxＯＰＯＳɆＣ meetup. This is a write-up on the 0xF09F8EA3 edition Microsoft Active Directory challenge. Since it is my first challenge dealing with AD and domain controllers, some field notes and introductory notes are also presented.
Those who are hardware tinkers and hackers know how easy it is to accumulate hardware thingies: single-board computers, microcontrollers, sensors and so on. One of those are Raspberry Pi’s of different version that lay around accomulating dust. It was time to give some usage to those idle computing resources in the form of a cluster for doing some experiments with networking, distributed computing, automation, etc.
There are places over Portugal where fibre connections are still a mirage, and all we’ve got are DSL connections, more specifically Asymmetric DSL (ADSL). The ISP modem + router combo has been updated through the years, and some old ones have been left behind. One of those was a D-Link DVA-G3170i from 2011, which seemed a good practice target for some hardware reversing.
“Based in Porto, the ØxＯＰＯＳɆＣ group was started by g33ks who are passionate about security. The meetup primary mission is to discuss and tackle upsurging security issues by leveraging the expertise and know-how of members of the group.” This year edition of the Summer Challenge consisted of 13 challenges belonging to 4 different categories, namely: Misc (3), Crypto (3), Web (3) and Trivia (4).
