The mega-messenger from Meta is allegedly collecting user data to generate ad money, according to recent attacks on WhatsApp. WhatsApp strongly opposes these fresh accusations, but it didn't help that a message of its own appeared to imply the same.
There are two prominent origins of the recent attacks. Few experts are as well-known as Elon Musk, particularly when it occurs on X, the platform he owns. Musk asserted on the Joe Rogan Experience that "WhatsApp knows enough about what you're texting to know what ads to show you." "That is a serious security flaw."
These so-called "hooks for advertising" are typically thought to rely on metadata, which includes information on who messages whom, when, and how frequently, as well as other information from other sources that is included in a user's profile.
The message content itself is shielded by end-to-end encryption, which is the default setting for all 3 billion WhatsApp users. Signal's open-source encryption protocol, which the Meta platform adopted and modified for its own use, is the foundation of WhatsApp's security. So, in light of these new attacks, do you suddenly need to stop using WhatsApp?
In reality, WhatsApp's content is completely encrypted. There has never been any proof that Meta, WhatsApp, or anybody else can read the content itself. However, the platform you are utilizing is controlled by Meta, and it is aware of your identity. It does gather information on how you use the platform.
Additionally, it shares information with Meta so that it can "show relevant offers/ads." Signal has a small portion of WhatsApp's user base, but it does not gather metadata in the same manner. Think about using Signal instead for sensitive content. Steer clear of Telegram since it is not end-to-end encrypted and RCS because it is not yet cross-platform encrypted.
Remember that end-to-end encryption only safeguards your data while it is in transit. It has no effect on the security of your content on the device. I can read all of your messages, whether or not they are end-to-end encrypted, if I have control over your iPhone or Android.
OpenAI has officially entered the web-browsing market with ChatGPT Atlas, a new browser built on Chromium: the same open-source base that powers Google Chrome. At first glance, Atlas looks and feels almost identical to Chrome or Safari. The key difference is its built-in ChatGPT assistant, which allows users to interact with web pages directly. For example, you can ask ChatGPT to summarize a site, book tickets, or perform online actions automatically, all from within the browser interface.
While this innovation promises faster and more efficient browsing, privacy experts are increasingly worried about how much personal data the browser collects and retains.
How ChatGPT Atlas Uses “Memories”
Atlas introduces a feature called “memories”, which allows the system to remember users’ activity and preferences over time. This builds on ChatGPT’s existing memory function, which stores details about users’ interests, writing styles, and previous interactions to personalize future responses.
In Atlas, these memories could include which websites you visit, what products you search for, or what tasks you complete online. This helps the browser predict what you might need next, such as recalling the airline you often book with or your preferred online stores. OpenAI claims that this data collection aims to enhance user experience, not exploit it.
However, this personalization comes with serious privacy implications. Once stored, these memories can gradually form a comprehensive digital profile of an individual’s habits, preferences, and online behavior.
OpenAI’s Stance on Early Privacy Concerns
OpenAI has stated that Atlas will not retain critical information such as government-issued IDs, banking credentials, medical or financial records, or any activity related to adult content. Users can also manage their data manually: deleting, archiving, or disabling memories entirely, and can browse in incognito mode to prevent the saving of activity.
Despite these safeguards, recent findings suggest that some sensitive data may still slip through. According to The Washington Post, an investigation by a technologist at the Electronic Frontier Foundation (EFF) revealed that Atlas had unintentionally stored private information, including references to sexual and reproductive health services and even a doctor’s real name. These findings raise questions about the reliability of OpenAI’s data filters and whether user privacy is being adequately protected.
Broader Implications for AI Browsers
OpenAI is not alone in this race. Other companies, including Perplexity with its upcoming browser Comet, have also faced criticism for extensive data collection practices. Perplexity’s CEO openly admitted that collecting browser-level data helps the company understand user behavior beyond the AI app itself, particularly for tailoring ads and content.
The rise of AI-integrated browsers marks a turning point in internet use, combining automation and personalization at an unprecedented scale. However, cybersecurity experts warn that AI agents operating within browsers hold immense control — they can take actions, make purchases, and interact with websites autonomously. This power introduces substantial risks if systems malfunction, are exploited, or process data inaccurately.
What Users Can Do
For those concerned about privacy, experts recommend taking proactive steps:
• Opt out of the memory feature or regularly delete saved data.
• Use incognito mode for sensitive browsing.
• Review data-sharing and model-training permissions before enabling them.
AI browsers like ChatGPT Atlas may redefine digital interaction, but they also test the boundaries of data ethics and security. As this technology evolves, maintaining user trust will depend on transparency, accountability, and strict privacy protection.
When browsing online, your device usually connects directly to a website’s server. However, in certain cases, especially for privacy, security, or access control — a proxy server acts as a go-between. It stands between your device and the internet, forwarding your web requests and returning responses while showing its own public IP address instead of yours.
According to the U.S. National Institute of Standards and Technology (NIST), a proxy server is essentially a system that handles requests from clients and forwards them to other servers. In simple terms, it’s a digital middleman that manages the communication between you and the websites you visit.
How a Proxy Server Operates
Here’s how the process works:
1. Your computer or device sends a request to the proxy server instead of directly contacting a website.
2. The proxy then forwards that request to the destination site.
3. The site responds to the proxy.
4. The proxy returns the data to your device.
From your perspective, it looks like a normal browsing session, but from the website’s end, the request appears to come from the proxy’s IP address. Proxies can exist as physical network devices or as cloud-based services that users configure through system or browser settings.
Companies often use “reverse proxies” to manage and filter incoming traffic to their web servers. These reverse proxies can block malicious activity, balance heavy traffic loads, and improve performance by caching frequently accessed pages.
Why People Use Proxy Servers
Proxy servers are used for several reasons. They provide a basic layer of privacy by hiding your actual IP address and limiting what websites can track about you. They can also make it appear that you’re browsing from another location, allowing access to region-locked content or websites blocked in your area.
In workplaces and educational institutions, proxies help administrators restrict certain sites, monitor browsing activity, and reduce bandwidth consumption by storing copies of commonly visited web pages. Large organizations also rely on proxies to safeguard internal systems and regulate how employees connect to external networks.
The Limitations and Risks
Despite their advantages, proxy servers have notable limits. They do not encrypt your internet traffic, which means that if your connection is not secured through HTTPS, the information passing through can still be intercepted. Free or public proxy services pose particular risks, they often slow down browsing, log user activity, inject advertisements, or even harvest data for profit.
For users seeking genuine privacy or security, experts recommend using paid, reputable proxy services or opting for a Virtual Private Network (VPN). VPNs extend the idea of a proxy by adding encryption, ensuring that all traffic between the user and the internet is protected.
Proxy vs. VPN vs. NAT
Although proxies, VPNs, and Network Address Translation (NAT) all sit between your device and the wider web, they function differently.
• Proxy: Masks your IP address and filters traffic but does not encrypt your connection.
• VPN: Encrypts all online activity and provides a stronger layer of privacy and security.
• NAT: Operates within routers, allowing multiple devices in a household or office to share one public IP address. It’s a background process, not a privacy tool.
Proxy servers are practical tools for managing internet access, optimizing traffic, and adding basic privacy. However, they should not be mistaken for comprehensive security solutions. Users should view proxies as one layer of digital protection, effective when used properly, but insufficient on their own. For strong privacy, encryption, and security, a VPN remains the more reliable choice.
