How do you think Santa is handling cyberthreats? With Dangerzone of course! (Yeah, it took some training.) If you feel like testing his security team, you should know it has a challenge for you: Craft Santa a letter that can bypass Dangerzone's defenses and earn a bounty! πŸ’°πŸŽ… […]

TITLE: Emergent Security Advice against ICE’s Kidnapping Spree
Subtitle: A Practical, Timely, Semi-Local Guide to State Resistance

Text: The current Trump administration is engaged in a monstrous campaign of snatch-and-grabs, warrantless raids, and the arbitrary detention of brown and Black people in Chicago. For months, ICE, Border Patrol, and many other masked, unknown federal agents have forcibly shoved our neighbors into vans and out of Chicago at breakneck speeds. In some cases, federal agents intentionally crash into cars and attack the people inside of them. But Chicagoans are
notoriously tough people and we’ve seen numerous organic, spontaneous mobilizations emerge to shatter ICE.

That being said, our collective security culture needs to respond to the harsh reality that these governmental actors simply don’t care about our rights, humanity, or dignity. Our responses must, in turn, adapt to the new authoritarian tactics, techniques and procedures. After
all, we reject the detentions of all humans, with or without warrants, and what we are seeing on the ground can only be described as an aggressive application of State power.

Interactive β€˜ICE Detention Map’ shows 71% of detainees have no criminal record The detention map extracts immigration data that ICE is legally required to publish to let anyone see stats on detainees across the country.

NEW: ICE is legally required to publish detention statistics every 2 weeks. But the data is complex.

That's why the interactive "ICE Detention Map" automatically scrapes & visualizes ICE's data, which shows, among other things, that 71% of detainees have no criminal record.

β€˜Silencing courageous voices’: Israeli killing of Gaza journalists slammed Condemnation grows after targeted Israeli attack assassinates correspondent Anas al-Sharif and several other colleagues.

In a just world, there would be an investigation and accountability for Israel committing this horrific crime.

But we all know that's not going to happen, unless and until governments stop using platitudes and actually put an end to this travesty at once.
