As mobile device usage continues to grow, so does the need for constant and convenient charging—especially in public spaces such as airports, hotels, cafés, and transport terminals. However, a now common cyber threat known as ‘juice jacking’ is emerging from these very conveniences.

What Is Juice Jacking?

Juice jacking is a cyberattack in which public USB charging ports or cables are tampered with to carry out malicious activity. When a user connects their phone or device to an infected charging station, the same USB connection used to transfer power may also be used to extract personal data or install malicious software without the user’s knowledge or consent.

Potential  compromise

1. Unauthorized access to personal files and credentials
2. Installation of spyware or other malicious applications
3. Hijacking of mobile money, email, or banking applications
4. Tracking of user activity and communications

How to Protect Yourself

To reduce the risk of juice jacking and enhance your personal cybersecurity, adopt the following safety practices:

1. Avoid using public USB charging ports. Where possible, use standard electrical outlets with your personal charging adapter.

2. Carry a power bank or portable battery. This allows you to recharge your devices safely while on the move.

3. Use charge-only cables or USB data blockers. These tools allow charging but block data transfer.

4. Do not use USB cables found in public spaces. They may have been tampered with to deliver malware.

5. Always decline “Trust this device” or data access prompts when connecting to unfamiliar charging sources.

NCSA urges all users to remain vigilant and treat unknown charging ports as potential risks to your digital security. By adopting safer charging habits and being cautious with your device connections, you play a vital role in safeguarding your personal information and the broader digital ecosystem.
