🖥️ Bạn đang tự host trên MacBook Air M1 và lo ngại bảo mật khi ra ngoài dùng Wi‑Fi công cộng?
✅ Chỉ chạy dịch vụ trên `localhost` → không quảng bá trực tiếp trên mạng LAN.
✅ Dùng Tailscale để truy cập nội bộ, tránh expose cổng ra internet.
✅ Khi kết nối Wi‑Fi công cộng, tắt hoặc vô hiệu hoá các service, bật firewall (pf/ufw), cập nhật macOS thường xuyên và bật VPN.

Evil Twin Wi‑Fi Hacker Jailed for Stealing Data Mid‑Flight https://hackread.com/evil-twin-wifi-hacker-jail-steal-data-midflight/ #Cybersecurity #CyberAttack #CyberCrime #PublicWifi #Australia #EvilTwin #Phishing #Privacy #VPN

An Australian national has been sentenced for operating “Evil Twin” WiFi networks targeting travelers in airports and on domestic flights.

Using a WiFi Pineapple, he cloned legitimate SSIDs and redirected users to phishing pages that harvested credentials and personal content.

AFP is urging the public to stay cautious with free WiFi - disable auto-connect, use a VPN, and avoid entering personal details on captive portals.

What security controls do you think would meaningfully reduce these risks?

Can’t connect to public WiFi via Linux

I am using Fedora 42, and I am unable to access the captive portal of inOui TGV. I can connect to the WiFi with no problems, but I can’t get access to the Internet.

I have tried everything:

1. Connecting to 192.168.1.1, to http://neverssl.com, to http://wifi.sncf via browser
2. Running sudo dhclient -r and rebooting the device
3. Running systemctl restart NetworkManager
4. Also other stuff I tried in the past with other public WiFis. I am sure there is something wrong with my specific device configuration, it’s not this network.

Nothing works 😩

Can somebody who understands this stuff help me?

It's time to take a closer look at app permissions and how you connect to wifi.

Many apps request access to data they don't truly need.

Why Limit App Permissions?

Enhanced Security: Granting unnecessary permissions can expose sensitive data if an app is compromised. Why let a flashlight app access your contacts?

Privacy Protection: Limiting location access prevents apps (and their advertisers) from tracking your every move. Do you really need that shopping app knowing your exact location 24/7?

Reduced Targeted Ads: Less location data means fewer creepy, hyper-targeted ads following you around the web.

How to Turn Off GPS (Location Services):

Android:

1. Open Settings.
2. Tap Location. (May be under "Security & Location" or similar)
3. Toggle the main Location switch OFF.
4. For more granular control, you can often see a list of apps and their location permissions. Choose "Allow only while using the app," "Ask every time," or "Deny."

iOS:

1. Open Settings.
2. Tap Privacy & Security.
3. Tap Location Services.
4. Toggle the main Location Services switch OFF.
5. You may also tap on individual apps to manage their location access (Always, While Using the App, Never).

Let's move into public wifi and its effect on device and personal security.

Free public wifi can be tempting, but it's often a security risk. While most websites now use HTTPS (TLS), encrypting the data between your device and the website, there are still vulnerabilities:

DNS Leaks: Your device uses DNS servers to translate website names into IP addresses. Without a VPN, these requests can be visible on public wifi, revealing what sites you're visiting.

Man-in-the-Middle Attacks: Malicious actors can set up fake wifi hotspots to intercept your data, even if it's encrypted.

Data Harvesting: Some public wifi providers collect user data.

Why are VPNs important when using public wifi.

First, what is a VPN. A VPN (Virtual Private Network) creates a secure tunnel for your internet traffic, encrypting your data and masking your IP address. Even with HTTPS, a VPN adds an extra layer of privacy by:

Hiding your DNS requests: Preventing others on the network from seeing what websites you visit.

Obscuring your IP address: Making it harder to track your online activity.

Protecting your data on public wifi: Shielding you from potential man-in-the-middle attacks.
In short: Take control of your mobile security! Limit app permissions, be cautious with public wifi, and consider using a VPN for enhanced privacy. Your digital self will thank you!
