Hackerangreb truer implantat-patienter

Sikkerheden i den trådløse teknologi, der bruges af indopererede insulinpumper og pacemakere, er kritisabel.

Pacemakere og insulinpumper kan slukkes eller omprogrammeres gennem fjernstyring. Det er nu blevet demonstreret af sikkerhedsfirmaet McAfee, der vurderer, at den fjernbetjeningsteknologi, som de nyere implantater rummer, er meget sårbar over for hacking.

I et praktisk forsøg efterviste sikkerhedsfirmaet, at det var muligt for hackere at påvirke en indopereret insulinpumpe til at tømme sit insulin-reservoir i en enkelt dosis. Nok til at forårsage patientens øjeblikkelige død.

Det er dog svært at opnå den nødvendige sikkerhed uden at øge strømforbruget. Hvis man krypterer kommunikationen, øges strømforbruget, og implantatet skal dermed udskiftes oftere.
