Por si no fuera suficiente con las últimas razones para convertirse en una persona paranoica, si has comprado un auto durante los últimos años es muy probable que corras un alto riesgo de que sea robado gracias a tus propias llaves.

Cada vez son más los conductores que hacen dan lugar a la recomendación de los especialistas y envuelven las llaves de sus autos en papel aluminio.

Ello se debe a que las llaves inalámbricas de los carros modernos están emitiendo señales hacia estos constantemente.

Así que ya sabes, así se sencillito: si tu coche tiene llaves inalámbricas y no te sientes seguro de dónde lo dejas, tan sencillo y barato es conseguir un rollo de papel aluminio casero y envolverlo. Piensa en una canción que constantemente se use entre una radio y una cerradura que se abre al escuchar esa canción.

La función del papel de aluminio es la de funcionar como una celda que bloquea a las ondas electromagnéticas, para que estas sean grabadas por alguien más. "Si conozco la canción, puedo abrir tu cerradura".

Así de sencillo se lo explica a BBC Mundo Moshe Shlisel, director general de GuardKnox Cyber Technologies, una agencia de ciberseguridad.

El especialista en ciberseguridad aseguró que "la industria automotriz está completamente al tanto de estos problemas y busca la manera de que sea imposible que alguien pueda replicar la comunicación entre una llave y un vehículo", pero hasta que eso suceda recomienda recurrir al "método aluminio" y dejarlas envueltas en todo momento.

Shlisel también mencionó que aunque aún no se cuenta con cifras exactas acerca de este tipo de crimen, los incidentes reportados suceden cada vez más frecuentemente.

Además, instituciones gubernamentales de Estados Unidos, por ejemplo, entregan ciertos documentos a sus usuarios dentro de carcasas especiales para evitar la transferencia y el robo de datos, como es el caso de la Green Card o Tarjeta de Residencia Permanente.
