Users of Line messaging app urged to change passwords after hack

Smartphone messaging application Line, which has hundreds of millions of users across Asia, was urging people to change their passwords Thursday as Japanese police investigated the hacking of hundreds of accounts.

At least 303 cases of unauthorised access were confirmed between late May and June 14, including three that involved cash trades resulting in financial loss, a Line spokesman told AFP, without providing further details.

“We are cooperating with police in investigating the cases, and we are calling for users to change passwords,” the spokesman said.

The accounts were hacked “presumably after shared passwords with other online services were leaked somewhere else,” he said, adding that to the company’s knowledge, all of the breaches occurred in Japan.

A police spokesman said the case was under investigation.

Set up in 2011, Line now has more than 400 million users, mainly in Japan and elsewhere in Asia, and is growing fast.
