How mobile network hacking works

Attackers may use a variety of tactics to carry out a cell phone network hack, but the process typically involves identifying the target, finding vulnerabilities, delivering malicious payload, exploitation, exfiltrating data, and covering tracks.

1. Identifying the target

Hackers often choose specific targets based on multiple factors, such as the value of the information stored on the device, the user’s profile, or potential financial benefit. Targets could be anyone; cyber criminals often pick targets based on what they can gain, weighing factors such as difficulty, risk, and potential take.

2. Finding vulnerabilities

Attackers search for weak spots in your device, operating system (OS), or installed applications. These vulnerabilities could also include outdated software or easy-to-guess passwords.

3. Delivering malicious payload

Upon discovering vulnerabilities in your phone, hackers deploy a malicious payload. This payload is a harmful component like a virus or spyware that can reach your mobile device through different methods, including hackers sending a phishing email, creating a fake Wi-Fi hotspot, or embedding the payload within an app.

4. Exploitation

After executing the malicious payload, hackers can exploit vulnerabilities to establish a foothold. These vulnerabilities could be weaknesses in the OS, outdated software, or flaws in specific apps.

5. Exfiltrating data

Once access is established, attackers may steal or exfiltrate sensitive data or even take full control of your device. This can lead to identity theft, financial fraud, or other malicious activities.

6. Covering tracks

Cybercriminals aim to stay undetected for as long as possible to maximize the damage they can cause and avoid capture. They often try to manipulate any evidence of their intrusion by deleting log files, altering timestamps, or modifying other data that could expose their activities.

Moreover, they may install backdoors to bypass normal authentication procedures and access a computer or network remotely without detection. Some attackers also use sophisticated techniques, namely encrypting malicious code, exploiting zero-day vulnerabilities, or using rootkits to avoid detection as they execute attacks.

9 common ways hackers attack on mobile

Cybercriminals use several techniques to conduct network hacking on mobile devices, like malicious apps, social engineering, phishing attacks, unsecured Wi-Fi networks, outdated software, SMS-based attacks, Bluetooth exploitation, weak passwords, and hardware exploitation.

Malicious apps

Malicious apps are software programs designed to compromise the security of a mobile device. They often appear legitimate but contain harmful elements such as malware, spyware, or ransomware, aiming to steal sensitive information or control the device.

Social engineering

Social engineering involves manipulating individuals into divulging confidential information or performing actions that may compromise security. Attackers exploit human psychology through techniques like impersonation, deception, or creating a false sense of urgency.

Phishing attacks

Phishing attacks, the most prevalent form of social engineering, involve deceptive tactics to trick users into giving out login credentials or personal data. Attackers often use fake websites, emails, or messages that mimic trusted sources to exploit user trust.

Unsecured Wi-Fi networks

Connecting to unsecured Wi-Fi networks exposes mobile devices to potential attacks. Hackers can exploit vulnerabilities in these networks to intercept data, launch man-in-the-middle (MITM) attacks, or distribute malware.

Outdated software

Attackers target known weaknesses in outdated software applications or OS to gain unauthorized access, install malware, or conduct other malicious activities.

SMS-based attacks

SMS-based attacks involve the manipulation of text messages to deceive users or take advantage of vulnerabilities in messaging systems. These attacks may include phishing attempts, malware distribution, or unauthorized access through SMS channels.

Bluetooth exploitation

This occurs when attackers leverage vulnerabilities in a device’s Bluetooth functionality to illegally access, distribute malware, or intercept data exchanged between devices.

Weak passwords

Guessable passwords make it easier for attackers to get illegal access to mobile devices or accounts. Using weak passwords or reusing them across multiple accounts increases the risk of unauthorized access and potential data breaches.

Hardware exploitation

While software protection is crucial for mobile network security, it’s equally vital to address hardware vulnerabilities that can undermine mobile network security. Attackers may exploit weaknesses in your device’s hardware components, such as baseband processors, SIM cards, Bluetooth, and Wi-Fi.

How to detect if your mobile device is hacked

There are signs you can look out for to detect mobile device hacking, including unusual battery drain, slow performance, excessive data usage, unfamiliar apps or frequent pop-ups, strange texts or calls, overheating, suspicious account activity, unexpected permissions, device behavior anomalies, and network irregularities.

  • Unusual battery drain: Your device’s battery is depleting rapidly, even with minimal usage. This could indicate that malicious processes are running in the background, consuming extra power.
  • Slow performance: Your device experiences sluggish response times, frequent delays, or crashes. This may be a result of hacking activities straining your device’s resources.
  • Excessive data usage: You notice a sudden and unexplained increase in data consumption. This could be a sign that malware or hacking tools are using your data to communicate with external servers.
  • Unfamiliar apps or frequent pop-ups: New and unfamiliar apps appear on your device without your consent, or you observe frequent pop-ups. Malicious software may install additional apps or generate unwanted advertisements.
  • Overheating: Your device becomes unusually hot, even during light usage. This may indicate that malicious processes are straining your device’s hardware, causing it to overheat.
  • Suspicious account activity: You detect unusual activity, unrecognized logins, or unauthorized access in your accounts. Hackers may get into your accounts through compromised devices.
  • Unexpected permissions: Apps request permissions that seem unnecessary for their declared function. Malicious apps may seek additional permissions to access sensitive data.
  • Device behavior anomalies: Your device behaves unexpectedly, such as turning on or off without input. Hacking activities can cause disruptions in normal device behavior.
  • Network irregularities: You observe network behavior irregularities, like frequent disconnections or unfamiliar devices connected to your Wi-Fi. Hacked devices may show irregularities in network connections.

Mobile network hacking prevention tips

While a mobile network can be hacked, there are many ways you can prevent it. Using strong passwords, updating software regularly, enabling two-factor authentication (2FA) or multi-factor authentication (MFA), avoiding public Wi-Fi usage, using HTTPS, being cautious with app permissions, securing your Bluetooth, and installing mobile security apps are some of the ways you can protect your device from network hacking.

  • Use strong passwords/PINs: Set strong and unique passwords or PINs for your mobile device and SIM card. Avoid using “1234,” “password,” or other easily guessable passwords.
  • Regularly update software: Keep your mobile device’s OS and all installed apps up to date to patch vulnerabilities and improve security. One of the simplest steps you can take is to turn on automatic updates for both your apps and OS to enhance protection.
  • Enable 2FA or MFA: Whenever possible, enable 2FA or MFA for your mobile accounts. This adds an extra layer of security aside from simply asking for a password by requiring more forms of verification, such as a code sent to your phone or fingerprints. 
  • Avoid using public Wi-Fi: Connecting to a public Wi-Fi exposes your personal data to anyone else using the network. Avoid using public Wi-Fi for sensitive activities or consider using a mobile virtual private network (VPN) to encrypt your internet connection on public Wi-Fi networks.
  • Use HTTPS: When browsing websites or using apps, ensure that you are using secure, encrypted connections (HTTPS). This helps protect data on your mobile network from hacker interception.
  • Be cautious with app permissions: Review and understand the permissions requested by mobile apps before installing them. Only grant permissions that are necessary for the app’s functionality. Limit the access to other information on your device, including your location, contacts, and photos.
  • Secure your Bluetooth: Disable Bluetooth when not in use, and make sure that your device is not set to be discoverable by other devices. This prevents unauthorized access or pairing.
  • Install a mobile security app: Consider using reputable mobile security apps with antivirus protection, anti-malware scans, and app permission monitoring to help protect your device from malicious software.
