I bought us-east-1.com: A Look at Security, DNS Traffic, and Protecting AWS Users

Owning the us-east-1.com domain was to protect AWS users from malicious actors who might misuse it for phishing or other attacks.
Owning this domain has provided fascinating insights into DNS queries—many of which are likely unintentional, generated by AWS resources and misconfigured systems.
prod-backend-db.cc66xuedqt2t.us-east-1.com is the most frequent DNS request suggesting a significant number of backend systems mistakenly reach out to this domain.
Domains like storagegateway.us-east-1.com and s3.us-east-1.com highlight how systems might inadvertently look to this domain for data, increasing the risk of data leakage if the domain were in malicious hands.
If someone else owned us-east-1.com, they could potentially set up a fake login portal that mimics the AWS Console, capture sensitive DNS queries that could reveal system configurations or IP addresses, use it as a phishing link to trick users into providing credentials or accessing malware.
Check DNS configurations, be mindful of typos and stay vigilant against phishing attacks to prevent sensitive information to unintended locations.
Leverage DNS Firewall to filter and regulate outbound DNS queries, preventing data exfiltration and accidental requests to unintended domains.
The primary goal is to ensure this domain remains out of the hands of bad actors and serves as a reminder of the simple yet effective ways we can improve cloud security by managing key assets, like domains.
Registering us-east-1.com is a simple yet effective step to secure AWS users worldwide.
For AWS users and anyone working with cloud services, it is a reminder to double-check configurations, always be wary of URLs, and adopt a proactive approach to security.

GPT-5: everything we know so far about OpenAI’s next frontier model

OpenAI is expected to launch its next-gen GPT-5 model soon.
The specific release date of GPT-5 is unknown, though it's expected to drastically outperform GPT-4.
There are rumors that this new model could arrive in late 2024 although there is debate on whether it will achieve AI.
OpenAI has said that its ambitious goal is to achieve Artificial General Intelligence.
Mira Murati, the former CTO of OpenAI is confident that the new model was still one and a half years away from release, which would certainly rule out a 2024 timeframe.
GPT-5 will bring larger knowledge base, enhanced reasoning skills and improvement in natural language processing and content generation abilities.
According to The Verge, the GPT-5 model will be launched this December. But an OpenAI spokesperson denied the statement that the company is not releasing a model code-named Orion this year.
The GPT-5 model won't be available in ChatGPT Plus version, at least initially it would reportedly work exclusively with certain partnerships only.
There has been significant pushback from the industry and public to development on anything beyond GPT-4.
OpenAI aims to allocate at least 20% of its computing resources for safety efforts across the entire company.

‘An existential threat’: anger over UK government plans to allow AI firms to scrape content

UK government's plans to allow AI companies to scrape content from publishers and artists is facing anger. The AI policy could lead to tech companies training their AI models using online content unless the content creators opt-out.
The proposed AI policy has lead to a series of meetings and roundtables being planned to address concerns.
Publishers fear an opt-out approach would be impractical as they may not know when their material is being scraped. Smaller publishers would be at risk if their work is used in training AI models.
The BBC said in a statement that its content should not be used to train AI models without authorisation.
An opt-in system would give publishers more leverage to agree licensing terms; an opt-out system would give control to AI developers.
Chris Dicker of the Independent Publishers Alliance said a system that scrapes anything posted online without explicit consent is a direct threat to privacy.
A government spokesperson said this is an area that requires thoughtful engagement; they will set out the next steps at the appropriate time.
UK risk being left behind unless it builds more data centres and lets tech firms use copyrighted work in AI models, warns Google.
A statement signed by over 10,000 people from the creative industries warns against unlicensed use of their work by AI companies.
The row illustrates the fundamental changes taking place after the arrival of AI chatbots; users can receive information without seeing the original publisher's work.

It’s finally time to stop buying Nvidia’s RTX 30-series GPUs

To get the best bang for your buck, it’s time to stop buying Nvidia’s RTX 30-series and look for other options.
The arrival of the RTX 40-series has cast a new light on the predecessor, and it's now mainly overpriced cards or unavailable, so don't waste your money.
Nvidia's RTX 40-series is now almost entirely under or at MSRP making it a financially sense choice, given the 30-series have risen in price again.
The then-overpriced RTX 3080 Ti came back down to a more reasonable level, but that still doesn’t make it worth the money in the current GPU climate.
AMD still has a bunch of solid cards in the RDNA 2 lineup, and many of them are dirt cheap at this point.
For Nvidia, your best bet is to buy current-gen GPUs.
Apart from buying new graphics cards, you can always look for renewed or used options.
We’re on the cusp of the RTX 50-series, and Ampere cards are soon becoming not just last-gen, but last-last-gen.
It’s time to bid farewell to a generation that was solid, but many of us never got to try it out for ourselves.
While it’s sad to see these cards slowly get replaced, it sure is a relief to see the GPU market overflowing with options.
