🔐 COSCUP x UbuCon Asia 2026 CFP closes in 3 days — and today happens to be World Password Day. World Password Day is a good reminder that cybersecurity is no longer only about passwords. It’s about the resilience of our infrastructure, communication systems, open source ecosystems, and digital society as a whole. That’s why COSCUP 2026 will continue to feature tracks related to cybersecurity and cyber resilience — and we would love to hear from contributors across the open source and security communities. 🌐 Cyber Resilience Topics around submarine cables, communication privacy, AI-driven disinformation, digital democracy, and infrastructure resilience are becoming increasingly interconnected. Cyber resilience is no longer just a technical challenge — it is also a social and public issue. 🛡 Hacks In Taiwan Conference After collaborating with HITCON last year, the security track returns again in 2026. This track focuses on cybersecurity from a developer-oriented perspective, creating more opportunities for developers and hackers to exchange ideas and making security topics more approachable for newcomers. We’re especially looking for talks and discussions around: • Open source security and risk management • Supply chain security, SBOM, vulnerability disclosure, and patch workflows • Authentication, passkeys, MFA, and real-world deployment experiences • Communication resilience and anti-disinformation efforts • Understanding security from the hacker perspective as a developer If you’ve been working on something interesting, don’t leave it buried in internal slides or private notes. Share it with the community at COSCUP. 📅 CFP Deadline: 2026/5/9 AoE 📨 Submit your proposal: pretalx.coscup.org/coscup-20… 📖 CFP announcement: blog.coscup.org/2026/03/cosc… #COSCUP2026 #UbuConAsia #HITCON #CyberResilience #CyberSecurity #OpenSource #OpenSourceSecurity
