Apple fixing iMessage flaw that lets hackers steal photos
Apple has put a lot of work into making its phones hard to crack, much to the consternation of US law enforcement officials. It's still not perfect, however, as researchers from John Hopkins University have discovered a flaw that lets attackers intercept and decrypt video and images sent on iMessage. The exploit only works on versions prior to iOS 9, because Apple partially fixed the problem in that version. However, John Hopkins professor Matthew D. Green told the Washington Post that a modified exploit could possibly be developed for iOS 9 versions, provided hackers have skills of a "nation state."
Life-saving vest shocks wearers' hearts to keep them alive
Apparently, 20 percent of patients who need to wear defibrillators don't actually keep them on at all times -- even if they mean the difference between life and death. So, a group of biomedical engineering students from the Johns Hopkins University designed a new type of wearable defibrillator, which is unobtrusive and comfortable unlike traditional harness designs. The undergrads' version takes on the form of a stretchable, waterproof vest fitted with sensors. Also, instead of using bulky control boxes to monitor the condition of a patient, its sensors are connected to a relatively small smartwatch-like interface.
