How to Protect Your Phone from Hackers: 7 Actionable Tips

Our phones are the digital diaries, wallets, and gateways to our lives. And this is why they are highly valuable targets for hackers - they store vast amounts of personal and financial data, are almost always connected to the internet, and are carried everywhere, all the time. Attackers exploit this ‘always-on’ characteristic through various tactics like phishing, malicious apps, and a growing wave of potential spam calls that are designed to deceive users and gain access to their phones.

Therefore, it is essential to learn how to protect your phone from getting hacked. Remember that whether it’s through phishing attacks, malicious apps, or exploiting outdated software, hackers can compromise your phone's data in several ways.

How to Protect Your Phone from Hackers: 7 Actionable Tips

Each of these practical steps will help you reduce your phone's vulnerability and ensure strong mobile security:

1. Use Strong Passwords or Biometric Locks

Begin by securing your device with a strong passcode that avoids common patterns such as sequential numbers or dates. Advanced authentication methods like fingerprint or facial recognition add a secondary level of protection. These measures are particularly effective if the phone is lost or stolen and help prevent unauthorized access.

2. Keep OS and Apps Updated

Regular updates to the phone's operating system and installed applications are essential for security. Updates often include patches for known vulnerabilities that cybercriminals exploit. Enabling automatic updates ensures the latest security protections are applied without delay.

3. Avoid Downloading Apps from Unverified Sources

Apps obtained from unofficial sources may contain malicious code designed to compromise your device. To reduce risk, install applications only from verified platforms such as Google Play or the Apple App Store, which conduct security screenings before approving apps. Reviewing developer credentials and user ratings also helps with reliability.

4. Do Not Click on Suspicious Links or Attachments

Phishing remains a widespread tactic to spread malware or steal personal credentials. With AI, it has even become easier for hackers to create targeted websites for phishing. These attempts often come in the form of deceptive text messages or emails. Refrain from clicking on links or downloading attachments from unknown or unverified senders, and verify the authenticity of unexpected communications. Otherwise, you can get hacked by responding to a text, even unknowingly.

5. Use Two-Factor Authentication Wherever Possible

Two-factor authentication enhances login security by requiring an additional step beyond the password, such as a code sent to your phone or generated through an authenticator app. This method provides extra protection against unauthorized access, especially in cases where login credentials have been compromised.

6. Review App Permissions Regularly

Applications often request access to device features and data that may not be necessary for their functionality. Periodically reviewing and limiting app permissions helps protect sensitive information. Both Android and iOS systems allow users to manage these permissions in the settings menu.

7. Use a Trusted Security Tool

Installing a mobile security tool strengthens your phone's defense against digital threats. Such tools offer features, including malware scanning, phishing detection, and real-time alerts for suspicious behavior. Guardio, for example, is a trusted security solution that offers both browser protection and a mobile app, with SMS filtering currently available on iOS. It flags dangerous websites and phishing attempts even when they’re disguised using AI or mimic trusted brands, and proactively alerts you to threats before you interact with them, whether you’re browsing, texting, or checking email. Unlike some security apps that only react after a threat is detected, Guardio anticipates risks based on patterns and behavior, helping you avoid scams and malware before they cause damage.

How Do Phones Typically Get Hacked?

Understanding the most common methods used by hackers to access mobile devices is the first step in strengthening your phone's defenses. Here are a few common ways phones get hacked:

1. Phishing Links via SMS, Email, or Websites

Cybercriminals often use deceptive tactics to send phishing messages that encourage users to click on malicious links or share confidential information such as login credentials or financial data. These messages can mimic legitimate organizations or trusted contacts, making them appear credible. Users may unknowingly provide sensitive information that can be exploited by attackers.

2. Malicious or Fake Apps

Some applications are designed to appear useful or entertaining but contain hidden malicious code. These apps may be found on unofficial app stores or disguise themselves as legitimate software. Once installed, they may request permissions beyond what is necessary, monitor your activity, or access sensitive information such as contacts and files without your knowledge.

3. Infected Websites and Browser Redirects

Compromised websites can exploit browser vulnerabilities to install malware automatically onto a user’s device. In some cases, users are redirected to these harmful websites through pop-up ads or embedded links. Drive-by downloads can take place without any action from the user, making this form of attack particularly dangerous.

4. Public Wi-Fi and Man-in-the-Middle Attacks

Free or unsecured public Wi-Fi networks can be easily manipulated by attackers to intercept communication between a user's device and online services. This type of attack is known as a man-in-the-middle attack. It allows hackers to observe and modify the information being transmitted, which could include login details, credit card numbers, or personal emails.

5. Outdated Software or OS

Devices that are not regularly updated often contain vulnerabilities that hackers can exploit. Older versions of an operating system or application may lack security patches that address newly discovered threats. Up-to-date software updates reduce the risk of unauthorized access and improve the overall security posture of the device.

Common Signs Your Phone Might Be Hacked

Recognizing the warning signs of a compromised phone is essential for preventing further security breaches and data loss. Here are some:

• Fast Battery Drain: A sudden reduction in battery life may be the result of malicious software operating in the background. Malware often runs continuously, consuming energy even when the phone appears to be idle.
  
  
• Slow Performance and Freezing: Performance issues such as lagging, freezing, or crashing can indicate the presence of unwanted software interfering with standard processes. These disruptions are often caused by background programs consuming system resources.
  
  
• Unrecognized Apps or Settings: Discovering applications you did not install or noticing unexplained modifications to system settings could suggest unauthorized access, including risks like phone cloning.
  
  
• Unexpected Data Spikes: A noticeable increase in data usage, especially if it occurs while your phone is not in active use, may point to malware transmitting information to external servers. Monitoring data usage can help identify such behavior.
  
  
• Constant Pop-Ups or Browser Redirects: A high volume of advertisements or frequent redirections to unknown websites may be symptoms of adware. This type of malware disrupts normal browsing activity and may also attempt to install additional malicious components.
  
  
• Overheating Without Heavy Use: Devices infected with malware may experience elevated operating temperatures due to high background activity. Persistent overheating without intensive use could be an indicator of a security issue.
  
  
• Poor Battery Health Notifications or Errors: Repeated system errors or alerts about declining battery health may be artificially triggered by malicious software. These alerts can be used to encourage users to install additional harmful apps or disclose sensitive information.

What to Do If You Think Your Phone’s Been Hacked

If you suspect your phone has been compromised, immediate action can prevent further data loss and restore device security.

Uninstall Suspicious Apps

Review all installed applications and look for any app that appears unfamiliar, was downloaded unintentionally, or is behaving abnormally. Removing these apps helps eliminate immediate threats and reduces the risk of ongoing unauthorized access or data collection.

Reset Passwords

Update the passwords for key accounts, especially those related to email, banking, social media, and cloud storage. Choose complex, unique passwords for each account, and consider using a password manager to securely store them. This action helps lock out attackers who may have gained access.

Clear Browsing History and Cache

Go to your browser settings and delete the entire history, cookies, and cached data. This step can eliminate embedded malicious scripts, remove any session hijacking remnants, and prevent reloading of infected pages or trackers.

Scan with a Trusted Security Tool

Use a trusted security tool like Guardio to strengthen your phone’s defenses. Guardio alerts you in real time when you interact with malicious links, phishing sites, or scam messages, helping you avoid threats before they cause harm. Its mobile app (currently available on iOS) includes SMS filtering to detect scam texts, while its desktop protection covers browser-based threats like malicious extensions and fake websites.

Consider a Factory Reset

If problems persist after initial remediation steps, back up essential files and perform a factory reset. This process restores your phone to its original state by removing all data and apps, including stubborn or hidden malware. After resetting, reinstall only trusted apps from verified sources to avoid reintroducing harmful software.
