Mayday! Mayday! If only your smartphone could scream these distress signals when it's being silently hijacked. Imagine you're at the airport, your flight is delayed and a notification appears: ‘10% battery remaining’. The familiar panic sets in.
Like most people, you probably look for the nearest charging station. However, that convenient USB charging station at the airports, shopping malls, or cafes might not be as safe as you think. They might be hiding a threat: juice jacking, a silent attack that siphons your data while charging your battery. In this blog, we’ll be diving into what juice jacking is and how you can avoid it.
Juice jacking is a type of cyberattack where criminals use public USB charging ports to steal data. When you plug your device into a tampered USB charger, you may unknowingly give hackers direct access to your personal information.
These fake charging stations are designed to transfer both power to your device and data from your device, potentially leading to data theft or malware installation. Your contacts, photos, and, most importantly, your banking and financial credentials can be stolen through juice jacking.
The Reserve Bank of India (RBI) and the Indian Computer Emergency Response Team (CERT-In) have recently issued a warning advising against using public USB charging stations due to the risk of juice jacking.
Cybercriminals tamper with public USB charging cells or strategically place charging cables in high-traffic areas. Then, an unsuspecting user connects their device to the compromised USB charging station, intending only to recharge their battery. Depending on the attacker's goals, they might silently copy photos, messages, emails, and financial information, install malicious software, or create backdoor access for future exploitation.
Protecting yourself from juice jacking doesn't mean giving up the convenience of charging on the go. Here are some tips to keep your devices safe:
Always make sure to carry your own charger, USB cable, or a power bank. It does require you to keep your power bank charged, but with little effort and mindfulness, you can save your data from hackers.
If you absolutely must use a public USB charger, power off your device completely before connecting. Many devices can charge while powered down, making data access much more difficult.
On Android phones, set USB connections to ‘Charge Only’ by default, and on iOS, navigate to Settings > Face ID & Passcode (or Touch ID & Passcode) > Allow Access When Locked and switch off the Accessories toggle.
Enable screen locks, use strong passwords, activate two-factor authentication for important apps like banking apps, and keep your device's operating system up to date. By doing this, you can ensure that layers of protection protect your device. It will make it harder for hackers to access your data even if they manage to connect to it.
Regularly check your bank statements, transaction history, and installed apps for any suspicious activity. After using public charging options, run a security scan on your device to protect it. Early detection of any compromise can minimize potential damage.

If you suspect your device has fallen victim to a juice jacking attack:
The convenience of public USB charging stations comes with hidden risks that every citizen should understand. Juice jacking attacks are a perfect example of how everyday technology can be weaponised against you to steal your data and misuse it.
Now that you understand what juice jacking means and some straightforward precautions to avoid it, you can continue using the convenience of charging on the go without compromising your security. If you reach for those public USB chargers next time, pause and consider whether it is worth the potential risk.
Juice jacking is a very real cybersecurity threat, as suggested by major financial institutions and security agencies worldwide, including the Reserve Bank of India.
Traditional juice jacking requires a physical USB connection that can transfer data. Wireless charging generally doesn't pose the same risk because it only transfers power, not data.
Both platforms are potentially vulnerable, though in different ways. iPhones now prompt users with a ‘Trust This Computer?’ message before allowing access to data.
Signs may include unusual battery drain, device overheating, apps opening spontaneously, strange notifications, or unexpected performance issues.
