Got my hands on some HaLow modems running on OpenWrt firmware! Next level mesh communication is about to happen. This is a game changer for Reaper Net!
🚨 Multiple cybercriminals were arrested during Operation SIMCARTEL. Europol and Latvian law enforcement dismantled five servers, seized 1,200 SIM box devices and 40,000 active SIM cards. The criminals were linked to over 1,700 cyber fraud cases in Austria and 1,500 in Latvia,…
I finally picked up The Code Book by @SLSingh. What I find just as interesting is the document released by the winners of the challenge in the book. Solve 5 rings crazy close to home recently.
With this new update from the @ReelLifeJustin hunt, it has me thinking about things again I skimmed over. - Did the distribution of the book have anything to do with special print requirements rather that logics? - The image analysis revealed interesting results. Some of which…
Want to see something truly scary? Grab a $30 SDR dongle and learn how RF works. The fact that every major state actor runs “listening posts,” and society is just now seeing this should make you think twice about what you know. wired.com/story/satellit…
Not documenting server and REST API's for a giant system is now coming back to bite me in the ass. I mean, what did I mean in the code by "Come back to this and fix it when you get a chance. You will know what I am talking about."? I have no idea what I was talking about!…
So did this Microsoft outage really just take down some of the cell networks and services as well!? Support systems for vendors are down as well. So, we shall wait.
I think I found a viable way to stop hosting platforms from logging mobile app IPs for BlackHaven Messenger. I’ll be standing up a set of lightweight VPN servers dedicated only to the REST API. Admins can opt in to enable this for their instance as a free feature. The app will…
As I do my code review and pen tests on my new E2EE communication software and app (BlackHaven Messenger), I found a potential pinch point if I am going to allow the system to run on shared hosting. Servers logging IP addresses.... But.. @ReelLifeJustin's NHP might be a fix for…
While code reviewing BlackHaven Messenger, I realized that I need to hash all User ID's to prevent meta data leaks correlating real user ID's with encrypted conversations. Todays goal.. Refactoring User ID logic to hash User ID's for conversations while still maintaining the…
Amidst the ongoing push for the construction of more and more massive energy-demanding data centers across the country, U.S. electricity prices for consumers have hit an all time high in 2025, according to Axios. As prices are expected to continue rising, likely surpassing $0.19…

Every time!
People are always the weak link! No matter how secure something is, if there is humans involved, there are ways.
According to an exclusive report by the Minnesota Star Tribune, the White House’s Deputy Homeland Security Advisor, Anthony Salisbury, was caught casually exchanging messages over Signal in a crowded, public space last weekend in Minnesota, discussing with a senior advisor to…
All the more reason for an app and system that allows users to control their own privacy without the worries of a single point failure when the government comes knocking. This is the whole reason I started building BlackHaven Messenger. I just might be releasing the entire…
We are alarmed by reports that Germany is on the verge of a catastrophic about-face, reversing its longstanding and principled opposition to the EU’s Chat Control proposal which, if passed, could spell the end of the right to privacy in Europe. signal.org/blog/pdfs/germ…
