Malicious software disguised as a computer game could have infected around 20,000 smartphones in South Korea, according to South Korean media reports quoting the country’s spy agency.

The games were offered through South Korean sites between May 19 and September 16 this year, the National Intelligence Service said in a report to parliament.

The apps have since been removed and the actual number of phones infected is unclear.

While phones were infected, the software doesn’t appear to have caused any damage but has left the phones vulnerable to eavesdropping and remote video taping, the reports said.
