Seismic monitoring devices linked to the internet are vulnerable to cyberattacks that could disrupt data collection and processing. Researchers from the National Observatory of Athens found non-encrypted data, insecure protocols, and poor user authentication mechanisms are among the biggest culprits that leave seismological networks open to security breaches. By exploiting these vulnerabilities, a malicious user could alter geophysical data, slow down data transmission and processing, or produce false alarms in earthquake early warning systems. Most seismologists and network operators are unaware of the vulnerabilities of their IoT devices, researchers say.
