The new Mariyung fleet has brought modern amenities like tray tables, accessible toilets, and charging ports. But with the convenience comes a potential risk: 'juice jacking', a cyber attack where public USB ports are used to steal data or install malware.
What is juice jacking?
Juice jacking occurs when a compromised USB port or cable is used to access a connected device's data. According to McAfee, this attack doesn't require sophisticated technology, and rogue charging ports can appear normal.
The Australian Signals Directorate (ASD) warns that public charging stations can put your data at risk. They recommend using trusted chargers instead of public ports.
Are Mariyung train USB ports safe?
Transport for NSW has confirmed that the USB outlets on the Mariyung fleet are power-only and contain no components capable of accessing or storing data. Passengers can also use three-pin outlets with their own adaptors.
"The power outlets are regularly inspected to detect any damage or interference, and repairs made when necessary," a spokesperson said.
How to protect yourself
To avoid juice jacking, use your own charger and cable. Carrying a portable charger also eliminates the need to use public ports. Keep your device software updated and disable data transfers when connected to USB ports in your phone's settings.
Another option is a 'USB condom' — a small adapter that blocks data transfer while allowing power to flow.
What to do if you suspect juice jacking
If you think your device has been compromised, disconnect immediately. Run a security scan to check for malicious files and remove any suspicious software. Then change your passwords and monitor your accounts for unauthorized activity.
By following these steps, you can enjoy the convenience of charging on the go without compromising your data security.
