AI is disrupting bug bounties. Security talent is being squeezed. The rules are changing. At #CyberThreat2025, Katie Moussouris explains what comes next — and how we prevent AI from eroding the expertise cybersecurity depends on. Watch now: bit.ly/4tJAam8

Last week at SANS London, the #UKCyberTeam took on a high-impact training day led by @xzer0f. Teams built real cloud services, then defended another team’s environment using only handover docs. A true test of teamwork, clarity, and pressure. #FutureCyber @SciTechgovuk

More good news! This weekend, the #UKCyberTeam gave back to the community by contributing 23 challenges to the @BSidesBRS CTF. The response was fantastic, and we’re so proud of the team for sharing their skills. Special thanks to @xzer0f for coordinating, QA’ing & deploying 👏

if you don't hand make the CPU you use, are you really a cyber security professional????!!!!!! /S

I'm assuming you conveniently forgot that the UK already has a law requiring users to hand over credentials / keys. This additional 'request' is a sweeping power too far and Apple have justly refused. You have also just embarrassed the UK by 'demanding'. Poor form!

Replying to @LukeGaughan @tomhfh
well for one the people who love encryption most are pedophiles. Even the US has a law ( dating way back) that forces platforms to proactively hand over some data.
Readers added context they thought people might want to know
Encryption is widely used and endorsed by banks, online services, governments, human rights orgs, and countless other institutions for safeguarding user data. For instance, X uses HTTPS encryption, and the UK GPDR recommends the use of encryption. ico.org.uk/for-organisati… en.wikipedia.org/wiki/HTTPS eff.org/encrypt-the-web securiti.ai/pci-dss-encryp… nsa.gov/Press-Room/Cyb… nytimes.com/2016/11/17/tec…

Replying to @SkyBet
@SkyBet says it “fundamentally disagrees” with the judgment and is considering an appeal. “Protecting our customers is the number one priority,” it said. After it engaged in social engineering a habitual gambler to gamble more, with targeted emails, free spins, bonus deals.

@Microsoft you quietly created a feature that prevents using custom domains in your #microsoft365 personal and family accounts, which I've purchased as gifts for family members. They are now useless and we'll be using Gmail from this point forward.. #OwnGoal #MissedThePoint
