Not me, writing a wrapper script for jFrog Boost ui for my raspberry pi to forward the dynamic port so I can view the boost web ui on my iPhone, as I do most of my agentic dev there, then having to also rewrite headers cos they added a host header set to localhost.

MSRC assessed an indirect prompt injection into Security Copilot as Low severity because consequential action still required downstream automation or human approval. That rationale gets much more absurd once security systems are explicitly designed to perceive, reason, and act autonomously.

Since iOS 27, the overlay text shortcut action won’t let me pick a font for the text. Tap on System to pick a font other than system does nothing. Existing shortcuts that have a font other than system still honour the selected font. Anyone else seeing this or found a fix/workaround?

The curious case of a control that’s supposed to cause near real-time evaluation of the access a user has so that risky access or even just disabled accounts lose access quickly, doesn’t trigger for a mobile app & Microsoft says it’s not a priority to fix because… the user already has access…

Continuous Access Evaluation: Is it really tho?
An investigation into Outlook Mobile continuing to access Exchange Online mailbox data after Conditional Access and Continuous Access Evaluation say the session should no longer be authorised.

Recreating my YouTube channel - given up on YouTube ever reinstating it or explaining what I did wrong! 3 old videos are back with new thumbnails. My previous disclosure videos I’ll resurrect from my laptop but I’ll also be filming videos for my upcoming disclosures on 14th and 16th September.

RIP Dolly Parton.

Never met her, never interviewed her (despite decades of unrequited requests) but thought she was utterly fabulous in every way.

One area of AI for good (for me at least) - I have arthritis in my left hand & de quervain syndrome in my right hand so using AI isn’t just an accelerator/force multiplier (in areas where I have domain knowledge & challenge BS), it also means less pain & strain in my hands for >= productivity.

When vibe coding, my preferred QA methodology is: “Delete reality and see whether the README can resurrect it.” Cos agents love to suggest false reality via the passing of tests they wrote 😂

If you implemented Tenant Restrictions v1 and only validated Restrict-Access-To-Tenants, you may only have implemented half the control you think you have. Latest blog in the #WhatTheEntraFudge series: cirriustech.co.uk/blog/wtef-en... #Entra #Microsoft #TenantRestrictions #Cybersecurity

What The Entra Fudge?! Tenant Restrictions v1 Doesn't Mean What You Think It Means
Tenant Restrictions v1 can block access to unapproved Entra tenants while still allowing Microsoft consumer accounts unless a second header is injected into a different authentication endpoint.
