Не имеет внешних, или иных подключений, не собирает данные, идеально дополняет DoH/DoT OpenBLD.net сервис.

Видео, как в принципе помогает жить OpenBLD.net приложено там-же на странице.

PyPI: Incident Report: User Account Takeover

reflection: This is not the first time I’ve seen developer accounts taken over, but if you think about it, what will happen. What if they take over, for example, the account of the developer of uBlock..? Where will they go or what will happen with your web requests being called back in it?)) In this context, the manifest v3 reduces such threats to a minimum...

The penetration testing execution standard consists of seven (7) main sections...

These cover everything related to a penetration test - from the initial communication and reasoning behind a pentest, through the intelligence gathering and threat modeling phases where testers are working behind the scenes in order to get a better understanding of the tested organization, through vulnerability research, exploitation and post exploitation, where the technical security expertise of the testers come to play and combine with the business understanding of the engagement, and finally to the reporting, which captures the entire process, in a manner that makes sense to the customer and provides the most value to it..:

📢 OpenBLD.net IPv6 Pre-Release Testing

Last week, last month, this year... I've been meeting and talking to different people, and they all echoed the same sentiment - IPv6 is needed 💯

A few days ago, I got acquainted with VEESP.com, a company that generously provided OpenBLD.net with an incredibly fast server featuring a high-speed Ethernet connection 🛞

Abstract: Usually, I spend some time testing servers, then assign them a secondary role before introducing them to the production environment. However, this time was different...

I was so impressed 😱 with the veesp.com server's speed that it practically flew into production almost immediately... )

I believe this is a great opportunity to start exploring the IPv6 space. In this month or early 2024, I hope we can begin experimenting with IPv6!

If you're ready to participate in the preliminary testing, please let me know through this OpenBLD.net Pre-Release Testing Form. I will reach out to you directly when the time comes, and together we can strive to make this world even better 🌱

P.S. Thanks to veesp.com and everyone who gives incentive to take a step forward 🤝
