Ken Munro: GPS Spoofing — It’s Not Just About Location, But Time
A DEF CON 32 talk where security researcher Ken Munro highlights a lesser-known aspect of GPS attacks — time manipulation. Beyond altering location data, attackers can also shift system time derived from GPS signals.
In one case, an aircraft’s onboard time was pushed far into the future, causing digital certificates to become invalid and disrupting communication systems.
The talk explores the risks of such attacks and discusses potential defenses for aviation systems.
