Home security giant ADT and medical device leader Medtronic have both confirmed massive data breaches. ADT's breach, claimed by the ShinyHunters group, affects 5.5 million people, while Medtronic is investigating the theft of 9 million records. These incidents underscore the high value of 'Life-Critical Data.' The Bureau assesses that this data is being aggregated by threat actors to create 'High-Fidelity Personas' for advanced social engineering and insurance fraud.
