Employers of phone sex companies have been arrested on charges of taking
the personal information of 8,420,000 customers from rival companies and
sending about 100 million lascivious text messages to them.
The Cyber Terror Response Center of the Seoul Metropolitan Police Agency
arrested phone sex company officials, including Nam (38, female), and a
hacker, Lee (33), and indicted four others without detention. They are
charged with taking the personal information of customers (a violation
of the Information and Communications Law) such as security numbers and
cell phone numbers from other phone sex companies by hiring a
According to police, Nam and Kang (33), president of another firm, let
Lee, who is a professional programmer, break into servers for clients of
their 67 competitors and steal 8.42 million personal information items.
The suspects used Daepo phones established in other names, such as those
of homeless people whose resident registrations have expired and credit
delinquents, and duplicated cell phones in order to send text messages.
As a result, they have yet to pay the fees for sending the text
messages, which come out to 30 won for one message and approximately
three billion won for the 100 million messages in total.
In particular, they analyzed client usage statistics and classified
clients who used phone sex services for over one hour or frequently as
superior clients and focused on sending messages to them. The police
revealed that they made 2.5 billion won in profit over one year by
stealing 0.1 million customers from competitors.
Lee downloaded a hacking program, X-Scan, from a Chinese website and
broke into other phone sex companies servers 12,000 times to get client
It is estimated that the number of frequent users of phone sex companies
is around 30,000; the service charge is 500 won per a half minute and
60,000 won per hour.
More and more victims get text messages, then get connected to these
phone sex services and end up paying a huge charge.
This is the first time someone who broke into several servers at the
same time and took personal information has been caught, police said.
Communication service companies can check out Daepo phones by confirming
a client who used a phone excessively in a short time. However, their
passive attitude has resulted in shifting losses to customers.
