Phone Security in 2025: Protecting Yourself from Call-Based Hacking

By Mitch Rice

As technology advances, so do the methods used by cybercriminals to exploit vulnerabilities in our devices. One of the most concerning threats in 2025 is call-based hacking—where hackers use phone calls to trick, manipulate, or even gain unauthorized access to smartphones. With the increasing use of artificial intelligence (AI) and sophisticated hacking tactics, it is more important than ever to stay vigilant and protect your phone from such threats.

Can Hackers Really Hack Your Phone Through a Call?

While a simple phone call itself does not have the capability to inject malware into your phone, hackers can use call-based tactics to exploit users. Here are some of the common methods:

  1. Vishing (Voice Phishing): Scammers impersonate trusted entities (banks, government agencies, or tech support) to steal personal information.
  2. One-Ring Scam: A hacker calls and hangs up quickly, tricking you into calling back a premium-rate number that charges high fees.
  3. Caller ID Spoofing: Attackers use software to fake caller IDs, making it appear as if a legitimate company or government agency is calling.
  4. SIM Swapping Attacks: Fraudsters convince your mobile provider to transfer your phone number to their device, gaining access to sensitive accounts.
  5. Malicious Links in Follow-Up Calls: Hackers may send links via SMS or email after a call, tricking users into downloading malware.

The Growing Threat of AI in Call-Based Hacking

With AI and deepfake technology, scammers can now clone voices to impersonate loved ones or company executives, making their scams more convincing. Cybersecurity experts have reported a significant rise in AI-generated voice scams over the past two years.

How to Protect Your Phone from Call-Based Hacking

  1. Do Not Answer Unknown Calls

If you receive a call from an unfamiliar number, let it go to voicemail. If it’s important, the caller will leave a message. Hackers often rely on users picking up their calls to begin their schemes.

  1. Use Call Blocking and Screening Features

Most modern smartphones come with call screening and blocking options:

  • iPhones: Use “Silence Unknown Callers” to automatically send unknown numbers to voicemail.
  • Android: Use Google’s “Call Screen” feature to filter calls before answering.

You can also use third-party apps like Hiya or Truecaller to block potential scam calls.

  1. Beware of Social Engineering Tactics

Scammers often pressure you into revealing information by creating a sense of urgency. For example, they may claim that your bank account is at risk or that you owe money to the IRS. Always verify information by calling the official number of the institution instead of responding to the caller.

  1. Never Share Personal Information Over the Phone

Legitimate institutions will never ask for sensitive information like your passwords, Social Security number, or banking details over the phone. If in doubt, hang up and call the official customer service number.

  1. Enable Two-Factor Authentication (2FA)

2FA adds an extra layer of security to your accounts. Even if hackers gain access to your phone number through a SIM swap attack, they still need a second authentication method to access your accounts. Use app-based authentication (Google Authenticator, Authy) instead of SMS-based 2FA when possible.

  1. Monitor Your Phone Bill and Accounts

Check your phone bill regularly for any unauthorized charges. If you see unknown transactions or numbers, contact your service provider immediately.

  1. Use a Strong Voicemail PIN

Hackers can try to access your voicemail and retrieve sensitive information. Set a strong voicemail PIN that is hard to guess, avoiding simple codes like “1234” or “0000.”

  1. Report Suspicious Calls

If you receive scam calls, report them to:

  • FTC (Federal Trade Commission) in the U.S.
  • Your Mobile Carrier: Most carriers offer a way to report scam calls by dialing special codes like #662 (T-Mobile) or 7726 (SPAM) for other networks.

Future Security Innovations Against Call-Based Hacking

As hacking methods evolve, so does security technology. Some key advancements in 2025 include:

  • AI-Powered Call Screening: Companies like Google and Apple are enhancing call screening technology to identify scam calls before they reach users.
  • Blockchain-Based Caller ID Authentication: Future advancements in blockchain may help verify legitimate callers, reducing the effectiveness of caller ID spoofing.
  • Voice Biometrics Security: Some banks and companies are implementing voice recognition as an extra layer of security to prevent fraud.

Conclusion

Phone security in 2025 requires a proactive approach to prevent call-based hacking attempts. While hackers continuously develop new tactics, following security best practices—such as avoiding unknown calls, enabling 2FA, using call-blocking features, and staying informed—can significantly reduce the risk of becoming a victim.

By staying vigilant and using the latest security tools, you can protect your personal information and prevent hackers from exploiting your phone through deceptive calls.
