10 Tips to Protect Your Smartphone from Hackers and Malware
Advertisements
Protect your smartphone from hackers and malware is a critical need in 2025.
With the increase in financial transactions, personal data storage, and even control of home devices via cell phones, cybercriminals are more sophisticated than ever.
A report from the Kaspersky Lab points out that 76% of cyber attacks target smartphones, exploiting everything from fake apps to vulnerabilities in outdated operating systems.
But are users taking security seriously? Many still neglect basic measures like software updates and two-factor authentication, making them easy targets.
In this guide, we go beyond the obvious. You'll discover not only how protect your smartphone from hackers and malware, but also how to identify scams before it's too late.
1. Software Updates: The Shield Against Exploits
Ignoring updates is like driving a car without brakes—something will eventually go wrong. Manufacturers like Apple and Google release security patches monthly, fixing critical vulnerabilities.

In 2024, the Google disclosed that 60% of successful invasions exploited flaws already fixed in previous versions of Android. If you delay updates, you're essentially inviting hackers to a party.
Moreover, many users do not know that not only the operating system needs to be updated, but also all installed applications.
A study of Symantec showed that Outdated apps are the gateway for 40% mobile malware.

Practical example: Maria was using an iPhone with iOS 14, even after the release of iOS 16. A hacker exploited a flaw already fixed in the latest version and broke into her bank.
2. Two-Factor Authentication (2FA): The Difference Between Getting Hacked and Not
Passwords can be stolen, but combining something you know (password) with something you have (SMS code or authenticator app) creates an almost insurmountable barrier.
Major data leaks, such as the one from LinkedIn in 2021, showed that millions of accounts were compromised because users didn't activate 2FA. If you don't use it yet, you're playing digital Russian roulette.
++How to Choose Smart Devices for a Connected Home
In addition to SMS, applications such as Google Authenticator and Authy generate temporary codes that expire in seconds, making attacks phishing much more difficult.
Advanced tip: Avoid using phone numbers as a second factor if possible. SIM swapping (SIM cloning) is still a real threat.
3. Apps of Dubious Origin: The Modern Trojan Horse
Pirated apps or apps from unofficial stores are one of the main sources of malware infections. In 2023, ESET discovered that 30% of the modified apps contained hidden spyware or ransomware.
Many users fall into the trap of downloading “cracked” versions of paid apps, without realizing that they are installing a disguised virus.
Real example: A popular game, “Free Minecraft Premium APK,” was downloaded over 500,000 times before it was identified as malware that stole banking credentials.
4. Public Wi-Fi Networks: The Danger of Exposed Data
Connecting to an open network at an airport or cafe may seem harmless, but hackers use tools like Wireshark to intercept unencrypted data.
++WhatsApp Phishing: How Does It Work and Why Is It So Effective?
If you need to access something sensitive, like online banking, wait until you're on a trusted network. Otherwise, a VPN is essential.
Alarming fact: A survey of the Kaspersky revealed that 25% of the tested public Wi-Fi networks had suspicious interception activity.
5. VPN: Encryption that Saves Your Privacy
A good VPN (Virtual Private Network) creates an encrypted tunnel between your device and the internet, preventing snoopers from seeing your traffic.
Services such as NordVPN and ExpressVPN are reliable options, but avoid free VPNs – many sell your data to third parties.
Analogy: Using the internet without a VPN is like sending a postcard—anyone can read it. With a VPN, it's like sending a letter in a bulletproof safe.
6. App Permissions: Why Does a Game Need Your Location?
Many apps request unnecessary access to the camera, microphone, and contacts. Review these permissions regularly and restrict them to the minimum necessary.
On Android and iOS, you can deny permissions in real time or revoke them manually in settings.
Real case: A photo editing app was caught uploading users' private photos to servers in China. All because users granted unrestricted access to their gallery.
7. Automated Backup: Your Redemption Against Ransomware
If malware hijacks your files, having a recent backup means you won't have to pay a ransom.
Use solutions like Google Drive, iCloud or an external hard drive with encryption to protect your data.
Statistic: According to Sophos, 32% of ransomware victims who pay the ransom never get their files back.
8. Mobile Antivirus: Is It Worth It?
Yes. Programs like Bitdefender and Malwarebytes detect threats in real time, blocking malicious links and suspicious apps.
Although app stores filter malware, many slip through the cracks. An antivirus is an extra layer of protection.
9. Phishing: The Scam That Looks Legit
Phony bank messages, miraculous promotions, and even supposed fines are lures for data theft.
How to identify? Always check the sender's domain and never click on suspicious links.
Recent data: Scams via WhatsApp grew up 45% in 2024, according to Check Point Research.
10. Biometrics and Strong Passwords: No “123456”
Using facial or fingerprint recognition is more secure than simple passwords.
For more information, see:
If you need a password, create a complex phrase, such as “Café@Seguro2025!”, and use a password manager like Bitwarden or 1Password.
Frequently Asked Questions
1. Can I trust free antiviruses for Android?
Some are good, but many display intrusive ads or sell data. Opt for premium versions from trusted brands.
2. How do I know if my smartphone has been hacked?
Battery draining quickly, unfamiliar apps, or strange behavior are all signs.
3. Does VPN really protect against hackers?
Yes, but only on public networks. At home, your router should already have its own security.
4. Is iPhone more secure than Android?
In general, yes, due to the App Store's strict controls. But no system is 100% invulnerable.
