Invasion of privacy is also considered unethical, so proceed with caution and respect others' right to privacy.

5 Ways A Cell Phone Can Be Hacked To Listen To Calls

1. Use A Spy App

Spy apps are one of the most popular and easiest ways to hack into someone's smartphone remotely. These apps allow real-time access not only calls but also text messages, emails, browsing history, social media activity, GPS location, and more. Below are some of the most reputable and feature-rich spy apps on the market:

With Hoverwatch's stealth mode feature, you can can monitor phone calls without being detected by the device owner (Android only). The list of features includes social network chat tracking, location tracking, and even the ability to take screenshots of the target device's screen. It should be noted that a paid subscription is required to access all of Hoverwatch's features.

Word of caution: Using these spy apps without the target's consent can have severe legal consequences.

2. Bypass smartphone security: Pin Code, Pattern or Swipe lock

Passwords and lock screens are the first line of defense against unauthorized access to a person's smartphone. However, these security measures can be bypassed with enough persistence and the right tools. One such tool is specialized hardware, such as lock picking devices that can break into a phone using its charging port or unexpected entry points.

In my early days as a hacker, I would often try to exploit patterns and routines by guessing PIN requirements or identifying common patterns like birth dates or addresses. However, this brute force method can take time and requires physical access to the target phone – not ideal for an effective hack.

3. Exploit security vulnerabilities: Android vs. iOS

Identifying and exploiting phone operating system vulnerabilities is another method that experienced hackers use to gain access to someone's voice calls. Both Android and iOS have their own unique set of vulnerabilities that have been targeted in recent years.

In my journey as a cybersecurity expert, I have noticed that Android tends to be more vulnerable due to its open-source nature. There are more variants of Android devices running different versions of the software which may lack important security patches; but keep in mind – despite being more secure than Android,iOS is not immune either. High profile breaches like "Pegasus" have demonstrated that no platform is entirely secure.

4. Social engineering

Social engineering is a technique that manipulates people into revealing passwords, access codes, or other sensitive information. As an ex-hacker, I know firsthand how effective these tactics can be. Phishing attacks, for instance, use emails or text messages that appear to come from legitimate sources such as banks or popular websites but actually contain malicious links or solicit the target to divulge their credentials.

In my experience, the most successful social engineering attacks combine psychological manipulation with technical trickery. For instance, a hacker might impersonate a trusted acquaintance of the victim and contrive a plausible-sounding reason for needing the desired access.

5. Bluetooth: Bluebugging, Bluesnarfing, Bluejacking

Bluetooth is another method hackers exploit to gain unauthorized access to smartphones. These techniques vary in complexity and typically require physical proximity to the target device. Bluebugging allows someone to take full control of a phone’s Bluetooth connection and make calls without user consent. Bluesnarfing targets unencrypted data transfers between Bluetooth-enabled phones and headsets or other accessories, while Bluejacking sends unsolicited messages which are less harmful but can be annoying.

Although major advancements in Bluetooth security have been made in recent years to combat these vulnerabilities, it's still worth taking precautions by turning off your Bluetooth connection when not in use or pairing devices within protected or private environments.

Why would someone want to listen to phone calls?

Someone may want to listen in on live conversations for various reasons. Employers might want to ensure that their employees are not leaking sensitive information, while parents could be interested in monitoring their children's activities for safety reasons. Suspicious partners may also resort to dubious tactics out of curiosity, jealousy, or mistrust.

Protecting your phone: Strengthening digital privacy

Setting strong passwords and biometrics on your phone

Strong passwords are critical in preventing unauthorized access to your phone since they are often the first line of defense against would-be intruders. Use long and complex passwords with a mix of uppercase letters, lowercase letters, numbers, and special characters when setting a password. Additionally, enable fingerprint recognition, facial scanning, or other biometric features if your device comes with these options as they provide a higher level of security than just a password.

Important tips about operating system updates

Keep your smartphone's operating system up-to-date to ensure that you benefit from the latest security patches. Hackers often exploit known vulnerabilities in outdated software, so it's essential to install updates as soon as they become available. Check for updates regularly and never ignore system update prompts.

Using safe and secure apps on your device

Only download apps from official app stores such as Google Play Store or Apple App Store, as these platforms have built-in security measures and vetting processes to ensure that their offered apps are trustworthy. Additionally, pay attention to user reviews and ratings, which can serve as useful indicators of an app's trustworthiness and quality.

Avoiding shared Wi-Fi and Bluetooth networks

Shared or public Wi-Fi networks may have weak encryption protocols or may even be set up by criminals to intercept data transmission. It is best to avoid these networks altogether; however, if necessary, use a VPN (virtual private network) when connecting to public Wi-Fi hotspots for added protection of sensitive data transmissions over the internet.

In addition, keep your Bluetooth connection off when not actively using it since potential vulnerabilities could be exploited by someone in close proximity who might attempt an unauthorized connection.

Securing messaging apps with end-to-end encryption

To prevent unauthorized access to your calls and messages through eavesdropping or intercepted communication, use messaging apps that provide end-to-end encryption like WhatsApp or Signal. This ensures that only the sender and receiver can read the content of a message because it remains encrypted while passing through different servers or networks.
