The Upbit cryptocurrency exchange has started the alarming service against phishing.

It automatically sends a warning message through Kakao Talk to customers when suspicious people log in the Upbit site. The warning comes out when people log in from overseas, virtual private networks and suspicious Internet Protocol sites

Once its customers get a warning message, he or she can push the button to log out the site, thus helping them from phishing.

An Upbit spokesman said many phishing sites abuse Upbit for taking out money from innocent investors. The exchange would strengthen monitoring of phishing and upgrade security.

In its website, it details cases of cryptocurrency frauds and how to cope with fraudsters.
