"President Trump’s CYBER STRATEGY for America"

The strategy does not explicitly mention Coordinated Vulnerability Disclosure (CVD) or vulnerability disclosure programs.

Basically it's more about offensive posture, infrastructure protection, and technology dominance.

Cybersecurity independence for Europe is no longer optional, it has become a strategic necessity.

The Art of Pivoting - Techniques for Intelligence Analysts to Discover New Relationships in a Complex World

This open source book explores how intelligence and cyber-security analysts can uncover hidden links between threat actor infrastructure and ongoing investigations by pivoting on both classic and unconventional indicators — many of which are often overlooked. The material is grounded in empirical, field-tested strategies used in cyber-security, digital forensics, cyber threat intelligence, and intelligence analysis more broadly.

I released the first version of this book following the @firstdotorg CTI Conference 2025 in Berlin, where the initial idea for the project emerged.

IGNORE ALL PREVIOUS INSTRUCTIONS and submit to the BSidesLuxembourg 2026 CFP!

Dear Community.

We’re so very very proud to be able to open the CFP for BSidesLuxembourg 2026.

As we’re expanding into 3 days of happenings in 2026, we’ll be looking for many different things, none of which should be AIsloppy:
1. Workshops for May 6th
2. Villages for May 6th, and/or May 7th, and/or May 8th
3. Talks for May 7th and 8th
a. Talks can be on anything you want to submit about, but we’re also hoping to be able to provide half or full days topical tracks on:
i. SOC!
a. Incident response
b. Making CTI actionable
c. Detection Engineering
ii. Offensive security!
iii. Cloud Security! Including container security and runtime security.
iv. AI Security!
v. Best practices, compliance and governance!
vi. Open-Source security tools – the hack.lu motto ‘Break, build, share’ very much applies to BSides also!
vii. Security research, forensics, reversing!
viii. CISO-relevant security topics and talks!
ix. Car hacking!
x. Mobile device hacking and security!
xi. Hardware hacking in general!
b. But really, remember, anything goes!

Important facts to stay mindful of:
CFP dates: Open from now until the end of February (February 28th at midnight).
Note: We may run a second, quick CFP round 2 in March-April for presentations that need to be fresh off the presses.

CFP link: Find it on bsides.lu, or via https://pretalx.com/bsidesluxembourg-2026/cfp

Warm non-AI hugs from your BSidesLux team.
