Tech Tips: Android phone users, don't use Wi-Fi for free! If you mess up, you'll lose everything, Google warns...

Google recently advised Android users to stay away from public Wi-Fi. According to the company's warning, these networks are often unencrypted, making it easy for cybercriminals to steal bank details, passwords, or personal information. Google recommends "avoid using public Wi-Fi as much as possible," as it can act as a "Trojan horse," meaning hackers can gain backdoor access to your device.

Google has also advised 3 billion smartphone users to change their phone settings. The most important change is to turn off auto-connect to Wi-Fi. This warning is issued through the Google Safety Center and Android updates.

What are the dangers of using public Wi-Fi?
Public Wi-Fi (such as free Wi-Fi available in cafes, airports, or hotels) may seem convenient, but it can pose several security risks. Hackers can exploit these networks to steal your information.

1. Data Interception and Theft
When you send or receive something via the internet, such as logging in, sending an email, or making an online payment, that data travels through the network. If this data isn't encrypted, hackers can intercept it. Imagine you log in to your bank account using a cafe's free Wi-Fi. If that Wi-Fi isn't secure, a hacker could access your username, password, or bank details from the same network. As a result, your account could be emptied.

2. Man-in-the-Middle (MITM) Attack
In this attack, a hacker places themselves between you and the website. You think you're directly connected to the website, but in reality, the hacker first obtains all your information. For example, you visit www.amazon.in or a similar site, but the hacker redirects you to a similar website, www.amaz0n.in. You log in, and your password is passed to a hacker. This could lead to your account or card details being stolen.

3. Malware Infection
Downloading files from an unsecured network or website can introduce viruses or harmful software onto your device. These can harm your system or steal your personal information. For example, you visit a website to download a free movie. The site displays a fake "download button," which, when clicked, injects a virus into your laptop. As a result, your device slows down or your data is locked, and hackers can demand payment.

4. Identity Theft
When someone steals your personal information, such as your name, address, PAN card, bank details, etc., and misuses it, it's called identity theft. For example, if your KYC or PAN information is leaked from a website, a hacker could use it to open a new bank account or take out a loan in your name. As a result, loans could be taken out in your name, causing you trouble.

5. Fake Wi-Fi Hotspot
Hackers often create fake Wi-Fi networks that resemble real names. People accidentally connect to them, and all their data is then transmitted to the hacker. For example, imagine you're at an airport and see a network called Airport_Free_WiFi. But the network is actually AirportOfficialWiFi. You accidentally connect to the fake one. This could lead to the theft of your passwords, OTPs, and bank details. This risk is further exacerbated when you're conducting sensitive tasks (such as online banking).

If you must use public Wi-Fi...
If you must use public Wi-Fi, you can reduce the risk by taking these precautions. Below are step-by-step tips:
1. Use a VPN
Always use a reliable virtual private network (VPN). This encrypts your internet connection and prevents hackers from reading your data. It's important to avoid free VPNs and use paid VPNs like NordVPN or ExpressVPN.

2. Only Open HTTPS Websites
When viewing URLs in your browser, make sure the website starts with https:// and has a lock symbol next to it. Avoid HTTP sites, as they are unencrypted and pose a risk of data leaks.

3. Don't Perform Sensitive Tasks
Avoid banking, online shopping, or logging into accounts over public Wi-Fi. Always perform these tasks using your mobile data or personal network.

4. Keep Multi-Factor Authentication (MFA) On
Enable 2FA (Two-Factor Authentication) on all your online accounts. This will protect you from password theft.
