One in three mobile apps popular with Hong Kong users are vulnerable to hacks, according to a study.
These apps either have insufficient encryption features or lack authentication technology, Apple Daily reports, citing the Hong Kong Computer Emergency Response Team Coordination Center.
The agency said 34 percent of 130 apps in a random sample were found vulnerable to malicious attacks.
More than half were designed to enable securities trading, online shopping and travel booking.
Their weakness level ranged from “vulnerable” to “serious”.
However, digital wallet and payment services were rated “secure” or “most secure” in general in 87 percent of the sample.
Eric Fan, chairman of the Professional Information Security Association, said hackers can set up a fake Wi-Fi access point and use bogus authentication certificates to hijack mobile app data.
He warned users against relying on public Wi-Fi networks to transmit sensitive data.
Internet services provided by mobile network operators are safer as most are encrypted, Fan said.
Fan said users should try web browsers when sending sensitive data because these are more secure than apps.
