In case you are a medical institution, it may be worth blocking this in your firewall or if you're using the CMS features, at least search internet traffic logs for the IP 202.114.4[.]119 #iocs

Bijgevoegd een foto van een penseelkever. Omdat het de taak is van journalisten het beestje bij de naam te noemen. Ik heb mijn ontslag ingediend bij de NOS. Ik werk er met plezier, maar dat is triviaal. Het gaat erom dat we goed werk leveren - en de samenleving tot dienst zijn.

Hi, hello, we don’t have evidence of extant vulnerabilities, and haven’t been notified of anything. We follow responsible disclosure practices, and closely monitor security@signal.org respond & fix any valid issues quickly. So if you do have more info hit us up! But beyond this... ...we’ve put a lot of thought into making sure our structure and development practices let people validate our claims, instead of just taking our word for it. This is particularly important to me, since I saw the view from inside a massive tech co and observed how widely their claims could diverge from reality when openness, validation, and an actual commitment to principles were not prioritized. Unlike almost all tech orgs we also build with the belief that the only way to keep data safe is not to collect it in the first place. You can see this in action when you clock the vanishingly small amount of data we have been able to turn over when forced. We fight all subpoenas, and when we are forced to hand anything over, we fight to unseal them and post them here: signal.org/bigbrother/ I’ve provided some links below so you can go deeper. In brief: -- We use cryptography to keep data out of the hands of everyone but those it’s meant for (this includes protecting it from us). The Signal Protocol is the gold standard in the industry for a reason–it’s been hammered and attacked for over a decade, and it continues to stand the test of time. -- We engage in regular professional audits (last one completed late Jan 2024). -- We develop in the open, and leverage reproducible builds. A large community of infosec researchers closely scrutinizes every single update, combing through our repos and binaries. This means that any nefarious change that affects the security of the Signal Protocol, of our codebase, or of the binaries we ship, would be detected almost immediately even on platforms like iOS where reproducible builds are not currently possible (BTW, please pressure Apple to make them possible). This is like an immune system protecting Signal from malign forces–wherever they may be–and ensuring the safety of the millions and millions of people who rely on Signal for sensitive communications. (We’re really grateful that so many people care enough about privacy to dedicate time and energy to ensuring Signal’s robustness.) -- Finally, we’re also a nonprofit, which means we have no incentive to hype bullshit in order to get acquired or bought out–because even if someone did buy Signal, per the 501c3 tax code the money would need to be reinvested in a mission-aligned cause. github.com/signalapp/ signal.org/docs/ signal.org/blog/reproducible… signal.org/blog/signal-found…

Replying to @christopherrufo
There are known vulnerabilities with Signal that are not being addressed. Seems odd …
Community note
There is no evidence that suggests Signal has "known vulnerabilities that are not being addressed". Due to Signal's open source nature, among other factors, this is easy to verify. twitter.com/mer__edith/sta…

Onderzoek voor Humo: radicaliseren op TikTok is kinderspel. Ik maakte drie verschillende accounts aan waarop ik me voordeed als een 13-jarige met onschuldige hobby's, en telkens viel ik pijlsnel in een gewelddadige 'rabbit hole': neonazisme, zelfmoord en jihadisme. (1/14)

Vandaag heb ik gezien hoe een jonge activist van Extinction Rebellion door de politie aan haar haren over de weg werd gesleept. Iets later hoorde ik twee agenten tegen elkaar zeggen: ‘Wat doen we bij deze? Bokkenpootje of bij de neus?’ Agenten hebben iemands pols ontwricht en bij iemand anders een elleboog gebroken. Voor me werd een activist zo lomp de bus in gegooid dat hij even buiten bewustzijn raakte. Net als een oudere vrouw, die viel nadat de politie - zomaar, zonder waarschuwing - begon te duwen en te slaan. Ik ben zelf door een agent van achteren tegen de grond geslagen terwijl ik rustig ergens heen liep. Lees ik bij de NOS*: “Een politiewoordvoerder zegt in een reactie (…) dat "lichte dwang" is toegepast bij arrestanten die weerstand boden.” Fuck dat. En fuck fossiele subsidies. *) nos.nl/artikel/2515723-klima…

Partijfinanciën zeggen veel over een partij en de oprichters. Uit de financiën van #FVD en #BBB blijkt bijvoorbeeld dat enorme bedragen naar bedrijven van de oprichters gaan. Bij de #PVV lijkt op het eerste gezicht dat er nauwelijks geld omgaat in de eenmanspartij van Wilders. /2

De eendenslachterij in Ermelo straks bij #Zembla is op elke mogelijke manier fout: stikstof en ammoniak, verschrikkelijk dierenleed, corruptie, buurtbewoners in de tang. Knappe jongen die dat allemaal benoemt met scherpte én humor: dat is @pieterderks x.com/denieuwsbv/status/1602…
