I am a happy use of @firefox.com hence the shambolic attachment of almost 5GB of large language model in the Google chrome does not affect me. Do you use Chrome? What do you make of this new development?
“Genetics loads the gum and the chemical environment pulls the trigger.” Shocking to say the least. apple.news/nowPlaying/A...
An informative map of “civil liberties” score. Great to see the Czech Republic up there with the great democracies, unlike the UK and the USA. Thanks @the-independent.com article “It appears the Britain no longer believes in the right to protest”, dated 2026-03-29 Source monitor.civicus.org
💯agree with Mr Carney. I love his remarks and reference to President Václav Havel about “signs in the windows” youtube.com/watch?v=izDA...
My Christmas 2026 wish. How can I get convince Apple to make it happen? @stephenrobles.com

@stephenrobles.com have you experienced success with “Screen unknown callers”? I had to switch it off as it asked my wife for her reason for calling 😂. In fact it asked every caller despite many being in my contact list.
“Security theatre” - Security theater refers to security measures that make people feel more secure without doing anything to actually improve their security. — Bruce Schneier (www.schneier.com/essays/archi...) This hotel door security chain fits that definition perfectly.
@martinlewis.moneysavingexpert.com Hi, seems Facebook is again profiteering from fraudulent advertisement. This time you are allegedly being arrested! Link: l.facebook.com/l.php?u=http...
@stephenrobles.com Apple stopped working on fixing issue in Find My in family - I am not able to set notification in Find My for my daughter when is leaves a location when is not at a given location (school). I sent paper letter to Federighi, got some contact but it died down. Worth a discussion?
In my previous article, I wrote about the inherent incompatibility of Active Directory with modern enterprise security architectures and cloud strategies. Another design vulnerability was presented at BlackHat USA on 6th August 2025. #cybersecurity vladimir.jirasek.uk/blog/2025/08...

Our latest @rapid7.com analysis does a deep dive into the #ransomware eco-system revealing "80 active groups in Q1, 16 of them new since January 1. There are also 13 groups that were active in Q4, 2024, but have thus far been silent in 2025" www.rapid7.com/blog/post/20... #malware #cybersecurity
Well done to @troyhunt.com for owning his Mailchimp data breach. Not so much “well done” to Mailchimp for now support FIDO Passkeys yet!!
For IT managers in SME: if you want a secure yet convenient remote access to company devices, I recommend RustDesk and @tailscale.com Configure RustDesk not allow direct IP access and not to advertise anything to the Internet. The security of connection is delivered by Tailscale.
@nathanmcnulty.com thank you for the excellent podcast on operational groups. It’s great to see the ingenious ways to plug vast gaps that Microsoft leaves in their disjointed products.

@proton.me Hi. Are there proton apps for Linux (I use Fedora), especially Drive, Mail proxy and Pass?
Since Apple might take away Advanced Data Encryption from existing users in the UK, I’ve been on the hunt for a better alternative. And guess what? I found one. It’s called Syncthing from syncthing.net and is proudly mentioned on the SecurityNow podcast.
website setup and a new page added: Apple resources - useful tools and videos for Apple users. Especially those migrating from Windows. vladimir.jirasek.uk/resources/ap...
Yesterday, 24th February 2025, I received the heartbreaking news that one of the cybersecurity vendors I had worked with since 2006, Skybox Security, has closed its doors. My thoughts are with all the former employees whose lives have been suddenly disrupted. vladimir.jirasek.uk/blog/2025/02...
OWASP Foundation support many initiatives. One of them, OWASP Top 10 for LLM Apps & Gen AI Agentic Security Initiative, have released an updated version of “Agentic AI - Threats and Mitigations” document. Link: genaisecurityproject.com/initiatives/ #agenticai #owasp #threatmodeling
Allegedly the owner of the company “Dr. Schwartz disregarded basic security measures necessary to protect that information from malicious cyberattacks” #health #cybersecurity thanks @404media.co for the article www.404media.co/beverly-hill...
It is going to be long evening. A Netflix series based on my favourite book by @markrussinovich.bsky.social is out today!
