Juice Jacking: Protect Your Mobile Device While Charging In Public Places


Do not charge your mobile phone on a public charger without having security guarantees that it cannot be hacked.

What is juice jacking?

Juice jacking is a form of cyber attack that involves tampering with electronic device charging stations, such as public USB ports or USB charging stations in public places, to steal data from a device when it is connected to the power source. The term ‘juice jacking’ is a play on words that combines ‘juice’ (juice or electrical energy, in reference to the charge) and “jacking” (to take or steal).

The way juice jacking works is that attackers can physically modify or install malware on the USB charging station so that when someone plugs in their device to charge it, data is copied or transmitted from the device to the attackers without the knowledge or consent of the owner of the device.

Juice jacking operation

This cyber attack technique is based on exploiting users’ trust in charging stations available in public places.

When a user connects their device to a compromised charging station, attackers can leverage the USB connection to install malware on the victim’s device or physically modify the charging station. This manipulation allows personal data, passwords, and other sensitive information to be copied or transmitted from the victim’s device to the system controlled by the attackers , all without the knowledge or consent of the device owner.

Types of attacks

There are four most well-known types of juice jacking attacks that require technical expertise on the part of criminals:

Malware installation

Attackers can install malware on the charging station or the charging device itself. When a user plugs in their device, malware is executed and can steal data from the device or even take complete control.

Wiring manipulation

In some cases, attackers can physically modify the USB charging station’s wiring to act as a data transfer device in addition to the power source. This allows copying of data without the user’s knowledge.

Distribution of malicious loaders

Malicious USB chargers look like legitimate chargers, but are designed to steal data when connected to a device. Attackers can leave these chargers in public places for users to inadvertently use .

Committed Public Shippers

In some situations, attackers can compromise existing public charging stations, either by physically modifying them or by installing data capture devices on them.

Risks and dangers of juice jacking

Theft of sensitive data

The main risk of juice jacking is the theft of sensitive data . When a user connects their device to a compromised charging station, attackers can access and copy personal data, passwords, financial information, and other sensitive data without the knowledge or consent of the device owner.

Malware infection

Electronic devices can be infected with malware when connected to a compromised charging station. This can result in malicious programs running on the device, which can lead to data theft, system damage, or even complete control of the device by attackers.

Privacy threat

This type of attack represents a direct threat to user privacy . Personal and confidential information can be compromised, which can have a negative impact on people’s lives, both personally and financially.

Possible reputational damage

If a user’s personal or private data is compromised due to juice jacking, this can have a significant impact on their reputation. Loss of confidence in the security of a device or service can be detrimental to companies and individuals.

Fraudulent use of data

Stolen data can be used fraudulently by attackers. This may include using financial information to commit fraud, unauthorized access to online accounts, and other cybercrimes.

Tips to protect your device

Avoid public charging stations

The first and most important tip is to avoid using public or unknown USB charging stations. Instead of plugging your device into a charging station in public places, use your own charger and charging cable.

Bring your own charger and cable

Always carry your own charger and USB cable with you. This allows you to safely charge your device anywhere without relying on public charging stations.

USB data adapters

Consider using USB data adapters that block data transfer when you connect your device to a public charging station. These adapters allow power charging only and prevent unauthorized data communication.

Keep software up to date

Keep your device’s software and apps up to date. Updates often include security patches that protect against known vulnerabilities.

Security awareness

Educates electronic device users, both personal and business, about the risks of Juice Jacking and the importance of cybersecurity. Promotes safe loading practices.

Visual inspection of the charging station

Before connecting your device, visually inspect the charging station for signs of tampering or suspicious cables. If something seems out of the ordinary, do not connect your device.

Uses AC Power Supplies

When possible, use AC power sources (outlets) instead of public USB ports to charge your device. This completely eliminates the risk of juice jacking.

Protect your device with passwords

Use passwords or screen locks on your devices to protect your data if it is lost or stolen. This adds an extra layer of security.

Disable Automatic Connection

Set your device to disable automatic data connection when connected to a USB charging source. This prevents any unwanted data transfer process from starting.

Real-time security updates

Use real-time security applications that protect against cyber threats and malware, and keep them updated.

Security tools and applications

There are a range of tools that can help neutralize this attack

Secure USB Data Adapters

Use secure USB data adapters that block unauthorized data transfer when you connect your device to a public charging station. These adapters allow power charging only and protect against juice jacking attacks.

Real-time security software

Install real-time security software on your devices. These applications, such as antivirus and antimalware , can detect and block cyber threats, including Juice Jacking attempts.

Mobile Firewalls

Use mobile device firewalls that monitor and control incoming and outgoing network connections on your device. This can help prevent unwanted intrusions.

Security updates

Keep your devices and apps up to date with the latest security updates . These updates often include patches that fix known vulnerabilities.

Data transfer lock

Set your device to automatically block data transfer when connected to a USB charging source. This prevents any unauthorized access attempts.

Password managers

Use password managers to keep your passwords secure and complex. This protects your data in case a Juice Jacking attack gains access to your device.

Data Encryption

Enable data encryption on your devices. Encryption ensures that even if attackers gain access to your data, they cannot read it without the proper encryption key.

Mobile security applications

Consider installing mobile security apps that offer additional protection features, such as security alerts and threat scanning.

Awareness and Education

Train users on the risks of juice jacking and the importance of practicing cybersecurity . Awareness is one of the most effective defenses.

App permission control

Review and manage app permissions on your devices. Make sure apps only have access to the information they need.
