If Trump arrests Putin in Alaska and flies him to The Hague, THEN he deserves a Nobel Peace Prize.

Krušnohorský či Litoměřický? Starosta Kadaně navrhl přejmenovat Ústecký kraj

Krušnohorský či Litoměřický? Starosta Kadaně navrhl přejmenovat Ústecký kraj

Starosta Kadaně Jan Losenický (ODS) navrhl přejmenovat Ústecký kraj. Podle něj má region špatnou pověst a podepisuje se na tom i negativní vnímání krajského města – Ústí nad Labem. Naopak například Litoměřice by prý byly lepším symbolem. Na tom, že je třeba zlepšovat image kraje a Ústí nad Labem jako krajské město dlouhodobě stagnuje, se v Událostech, komentářích shodli i se senátorem a historikem Martinem Krskem (za SEN 21).

How to waste a day debunking someone else's scoop:

Someone forwarded me this recent story from Straight Arrow News (a publication I didn't previously know existed) which rather breathlessly claimed millions of cars were at risk from new custom firmware sold by a Russian hacker that would enable Flipper Zero users to unlock the doors and trunks of countless makes and models of different cars for a few hundred bucks. Basically, turn the Flipper into a sub-Ghz repeater that can intercept and replay the radio signal sent out when someone presses their car key fob.

I was skeptical of this story because I recalled reading a blog post from Flipper last year after the Canadian government said it was going to ban flippers. In response, Flipper Devices wrote:

"We are not aware of any officially confirmed cases of theft using a Flipper Zero. This is because the device has limited functionality and can't be used as a repeater to attack keyless entry systems. Flipper Zero is equipped with only one sub-1 GHz radio module, while keyless repeaters have 4 radio modules: one for communication with the car, another one for communication with the key fob, and two for communication between the repeaters."

It took several hours of questioning the Russian guy on Telegram for him to admit that using his firmware successfully requires additional radio units and other stuff not pictured in most of his sales videos.

I asked him whether he was at all concerned that the Russian authorities might be interested in him, and he curtly replied that this was his concern, not mine. Later he asked why I'd asked this question.

It turns out, in one of his videos he replied to a comment by posting a Google Docs link to a spec and pricing sheet. Clicking "details" on the Google Docs file showed a username and author: daniel.v.dogaru@gmail.com. Searching on this address in breach tracking services finds it is associated with multiple Russian government records saying the email belongs to a guy from Moscow named Danil Viktorovich Doragu who uses the phone number 79267824950. That phone number is tied to a Telegram account for user "r3df0xx," and a search on this username in Intel 471 finds Daniel has been selling custom firmware for Flipper devices for several years. Oh, and his LinkedIn profile includes a link to the GitHub account "DarkFlippers."

Czech president signs law criminalising communist propaganda, placing it on the same footing as Nazi propaganda - SDF Chatter

Archived [https://web.archive.org/web/20250718042123/https://www.euractiv.com/section/politics/news/czech-president-signs-law-criminalising-communist-propaganda/] Czech President Petr Pavel on Thursday signed an amendment to the country’s criminal code that criminalises the promotion of communist ideology, placing it on the same footing as Nazi propaganda. The revised legislation introduces prison sentences of up to five years for anyone who “establishes, supports or promotes Nazi, communist, or other movements which demonstrably aim to suppress human rights and freedoms or incite racial, ethnic, national, religious or class-based hatred.” The change follows calls from Czech historical institutions, including the Institute for the Study of Totalitarian Regimes, to correct what they viewed as a legal imbalance.
