Major Internet access provider Nifty Corp. said Tuesday that a spate of illegal connections mainly from Russia are accessing the service using stolen subscriber passwords.
In an in-house investigation, the company found that more than 20 subscribers were affected. Nifty stands to lose millions of yen if the illegal connections are left unchecked.
Nifty plans to suspend 38 access points in Russia, Kazakstan and other countries this week. The company is also planning to ask for police assistance, a company spokesman said.
Nifty has laid out measures to curb illegal access after discovering a sharp increase in the number of cases from Russia, he said.
The company on Monday afternoon informed its subscribers via its Web site of the suspension of connections to Russia.
