AVOID PUBLIC WI-FI

Free Wi-fi offered in public places is often poorly secured. Hackers need only ordinary tools to access mobile phones linked to the network and the information the devices store.

DON'T OVERSHARE ONLINE

Internet users can let their guard down when chatting with strangers on social media, letting slip their names, family details, workplace addresses and job titles to their new “friends”. Some parents even share photos of their children online, forgetting to hide details that can disclose their names, schools or where they live.

AVOID ONLINE SURVEYS

Some questionnaires try to attract people with small rewards or a chance to take part in a “lucky draw”. But to qualify, people must fill in their names, phone numbers and home addresses. Check the website where the survey is being hosted and consider whether it's reliable.

KEEP ONLINE RESUMES BRIEF

Internet users often do not hesitate to provide detailed personal information in their online resumes, thinking it can only help probable employers to contact them. Some job site operators even require applicants to list their family members' information. China's Ministry of Public Security says people should give only the information necessary.

TRACK COPIES OF YOUR ID CARD

Banks, telecommunications operators and other service providers often require photocopies of your identity cards to open accounts or perform other business. Dishonest employees might then try to sell them to scammers (骗子).
