Juice Jacking

“Juice Jacking”, a term that might sound innocent but is far from it. This new-age digital theft tactic poses a significant threat to the security of our personal data stored on our devices. In this article, we delve into the details of this cyber-theft tactic, its potential consequences, and protective measures to counteract its effects.

Defining “Juice Jacking”

“Juice Jacking” is a form of cyber-theft that jeopardizes the safety of our personal data stored on electronic devices. It is executed via compromised USB port charging stations, offering unsuspecting victims free device charging. These charging stations, often found in public places like airports and hotel lobbies, could potentially harbour malicious software installed by cybercriminals.

Once a device is plugged in, the malware can infiltrate the device, enabling the perpetrators to access sensitive information such as personal data, passwords, and more. This stolen information can then be used for unauthorized access to online accounts or sold to other criminals.

Technical Feasibility and Known Instances

While “Juice Jacking” has been proven to be technically feasible and has been demonstrated as a proof of concept, no confirmed instances have been reported by the Federal Communications Commission (FCC). However, the lack of confirmed instances does not negate the potential threat posed by this cybercrime tactic.

Safety Measures Against “Juice Jacking”

To protect ourselves against potential “Juice Jacking”, here are some safety measures we can adopt:

  1. Use AC Power Outlets: Using AC power outlets instead of USB charging stations can minimize potential risks. Always carry AC and car chargers, along with your own USB cables, while travelling.
  2. Carry an External Battery: An external battery pack can be a lifesaver. It provides you with a charging option that doesn’t require you to use public USB ports.
  3. Use a Charging-Only Cable: Consider using a charging-only cable that prevents data from being transmitted while charging. Ensure that this cable is procured from a trusted supplier.
  4. Always Select “Charge Only”: If a prompt appears asking to select between “share data”, “trust this computer”, or “charge only” when you plug your device into a USB port, always opt for “charge only”.

Threats of Public WiFi Networks

Public WiFi networks are another avenue through which cybercriminals target travellers. For more information about mobile phone and online security, the FCC consumer guide offers insightful tips on Wireless Connections and Bluetooth Security.

“Juice Jacking”: A Warning from the New York Department of State

The New York Department of State’s Division of Consumer Protection has issued a warning about “Juice Jacking”, particularly as the peak travel season approaches. New Yorkers, and indeed everyone, are urged to take protective measures to reduce the risk of data theft when travelling. This warning comes in light of the increasing number of scams plaguing the marketplace.

“Summer is peak travel season when New Yorkers are constantly on the go heading to events, gatherings and vacations with friends and family,” said Secretary of State Robert J. Rodriguez. “Unfortunately, nefarious scammers are always at work finding new ways to target unsuspecting consumers and steal their personal information. If you need to charge your phone or any device while traveling, it’s important to pay attention to how and where you charge these items to protect yourself from falling victim to a potential ‘juice jacking’ scam.”

FBI and FCC Warnings

Both the FBI and the Federal Communications Communication (FCC) have also issued warnings about the “juice jacking” scam. The FCC has a dedicated webpage that provides further information about how malware installed through a corrupted USB port can lock a device or export personal data and passwords directly to a skimming perpetrator. Before using a public phone charger, consumers need to understand how hackers can steal data through these kiosks and that any device that requires charging via USB is vulnerable.

Additional Tips to Prevent “Juice Jacking”

To further safeguard against “juice jacking”, here are some additional tips:

  1. Use a Data Blocker: Consider using a USB device called a data blocker that connects to your phone’s charging cable and prevents data from being transmitted through the USB cord.
  2. Power Off Devices: If you must use a public charging station, power off your device before plugging it into the charging port.


“Juice Jacking” is a potential threat that can harm unsuspecting individuals. However, being informed and taking the necessary precautions can ensure the safety of your personal data. Stay vigilant, stay safe.
