“Cyber activists may take advantage of the large audience to spread their message. Cyber criminals may attempt to steal personally identifiable information or harvest users’ credentials for financial gain. There is also the possibility that mobile or other communications will be monitored,” the Homeland Security Department cautions those heading to South Korea Feb. 9 to 25 for the 2018 Winter Olympics.
The DHS National Cybersecurity and Communications Integration Center (NCCIC) and United States Computer Emergency Readiness Team (US-CERT) recommend that Olympics visitors:
- Switch off Wi-Fi and Bluetooth connections when not in use.
- Use a credit card to pay for online goods and services.
- When using a public or unsecured wireless connection, avoid using sites and applications that require personal information like log-ins.
- Update mobile software.
- Use strong PINs and passwords.
