Heartbreaking news 💔 Unfortunately, Positive Hack Days #PHDays is moving to 2027. To all the speakers I personally invited - hey, you know I'm hosting Positive Hack Talks #PHTalks around the world, and the next one is in Kuala Lumpur 🇲🇾 - I will be posting some news soon. To all the village communities I was so excited to bring to PHD - so sorry, I was genuinely hyped about this. Long story short: PHDays 15 was supposed to be our biggest milestone yet. The event is massive - there are only a handful of venues in Moscow 🇷🇺 that can even handle it. And when our main site went under reconstruction, the remaining options fell one by one for the same reason. No suitable venue = no way to build everything we ambitiously planned. We'd rather wait and do it right. So - 2027, new venue, no compromises. The 15th PHDays will be worth it. We'll see each other soon. Big hug to everyone 🫂

🚨 Our researcher Alexander Zhurnakov identified two vulnerabilities in Dell Wyse Management Suite prior to version 5.5. In certain configurations, they can be chained to achieve unauthenticated remote code execution. Upgrade now → dell.com/support/kbdoc/…
