Ukraine's emergency notification platform began distributing false alerts on Sunday, warning citizens of nationwide air raids, street fighting in Kyiv, and potential chemical and radiological hazards. Within hours of the initial breach, Russian authorities confirmed that their comparable civil warning network had also been hijacked by unauthorized users. Both governments attribute the disruptions to cyber-attacks targeting their critical communication networks. Officials have not established if the two security breaches are linked or who carried them out.

Ukraine's emergency alert app issued a nationwide air raid warning, as well as alerts for a radiological threat, a chemical attack and street fighting in Kyiv on Sunday evening - all of which turned out to false.
A few hours later, Russia said its equivalent app had also issued false alerts, with both countries claiming their systems had been hacked.
It is still unclear who is to blame for the cyber-attacks and whether the two incidents are connected - the BBC's cyber correspondent Joe Tidy explains what we know so far.
PostHog is abandoning its five-month-old data warehouse infrastructure after discovering that single-node architectures struggle with managed multi-tenant cloud workloads. The platform originally transitioned away from ClickHouse to offer isolated customer environments and broad Postgres tool compatibility, but unexpected query sizes forced expensive hardware overprovisioning. These operational hurdles, paired with storage catalog breakdowns at scale, prompted engineers to spend three months redesigning the entire…
Major technology conglomerates have accumulated authority akin to medieval feudal lords by controlling critical data, online marketplaces, and digital infrastructure. This dynamic forces independent workers and smaller enterprises into profound operational dependence, replacing open internet principles with corporate-governed territories. Consequently, traditional market competition is undermined as platform owners establish the rules and capture the economic value generated within their closed environments.
Commercial grocery chains across multiple European nations were forced to throw away spoiled stock after unauthorized intruders remotely compromised their internal refrigeration units. The incidents altered cooling controls overnight, pushing temperatures as high as 50 degrees Celsius in some locations. Investigators are still trying to determine who orchestrated the coordinated campaign across the continent.
