This week, we’re sharing two segments.
First up, a chat with Cooper Quintin, a senior staff technologist at the Electronic Frontier Foundation and developer of the Rayhunter. Rayhunter is open-source firmware to turn specific hotspots into IMSI-catcher, effectively scanning for and logging any signs of fake cell towers (often known under the brand-name of Stingrays) in the area. Law enforcement has at times deployed these as a way of collecting information about phones in the area and could use it to intercept some communications like sms or phone calls. Cooper talks about what’s known of law enforcement use of IMSI-catchers, what has been observed of the data collected by deployed Rayhunters, phone security at demonstrations and related topics.
Then you’ll hear Radio Ausbruch from Frieberg from this month’s B(A)D News podcast from the A-Radio Network talking about the repression and deBanking of anti-repression projects like ABC Dresden and Rote Hilfe in Germany based on pressure from the US government related to the so-called Antifa Ost case. This carries heavy implications for prisoner support, anti-racist and other social struggles.
