@christruncer @rvrsh3ll @_subTee You’ll need to come over to @Steel_Con and @digininja can cook some horror up
@0xTriboulet @Horizon3ai Congrats dude that’ll be fun!
Here's a small project I've been working on as a private project for a while but may be useful to folks for #bugbounties github.com/ZephrFish/MDRe…
Happy @Hack_Thursday, and happy Hack Glasgow speaker announcement! We're excited to announce that @ZephrFish and Alex Close will be presenting 'The Hunted Becomes the Hunter: Catching Red Teamers and Pentesters and Spotting Adversarial Patterns' at Hack Glasgow!
Imagine how cool it would be to see your design on a postcard and know 450 of them were sent out to people across the country? [email protected]
This announcement reflects legitimate concerns about children's safety online, but a ban of this scale would change how children access and experience the digital world. The UK Government must ensure that any decisions are informed by children themselves and by independent experts. We are concerned that a blanket ban may look protective on paper, but instead pushes children into less regulated spaces, where they are less likely to seek help when something goes wrong. Children growing up in poverty are likely to be among those most affected. If ministers want to make the online world safer, the answer is not simply keeping children off platforms. The focus must be on providing better support for parents by making platforms safer by design, tackling addictive and high-risk features such as stranger contact, live streaming, nudification tools and unsafe AI systems, so that children are not exposed to harm online.
Social media will be banned for all children under 16, UK PM Keir Starmer announces Follow live: bbc.in/4e8dZQK
My @BSidesLeeds talk went well
Just gotten back from @BSidesLeeds which was a fantastic event as always, thanks to everyone who came along to my talk, it was great to speak to so many people about such a diverse range of topics plus help those looking to break into the industry. A few folks asked about my course too, it can be found at lms.zsec.red and if you use code LTR101-10Y until end of August you can get 10% off too! I took the time this week in-between writing slides to reverse engineer the badge that @punksecurityuk put together for the BSides event and pulled the firmware apart and wrote it up as a blog post. You can find the full breakdown and write up here, warning it does spoil the functions of the badge so if you do want to hack it yourself be pre-warned: blog.zsec.uk/bsidesleeds202…
@irsdl @BSidesLeeds @grok This is why RAM is £4k
It’s @BSidesLeeds today and we’re sponsoring. Come along to @ZephrFish’s talk at 11.40 in Track 1 all about blending into environments using defensive tools and understanding. Our 10% off coupon is also still live: LTR101-10Y lms.zsec.red
I love this bsidesleeds.com/2026-speaker-a… only just noticed the label at the bottom 😅🤘
@_RastaMouse @BSidesLeeds You should put on your glasses
Our statement on the UK government’s demand that all content on all devices sold or used in the country be scanned, on the presumption of nudity, using a dystopian combination of age verification and content scanning. This proposal will not safeguard children. It endangers us all. signal.org/blog/pdfs/2026…
Looking forward to @BSidesLeeds next weekend where we’re sponsoring and @ZephrFish is giving a talk 💪
