Symbol Unicode groźny dla sprzętu Apple’a
Jeden ze specjalnych symboli Unicode powoduje awarie sprzętu Apple'a - twierdzi Bitdefender. Apple wprowadziło poprawki.

Posiadacze urządzeń Apple’a takich jak iPhone, iPad, Mac czy Apple Watch powinni uważać na specjalny symbol Unicode, który reprezentuję literę z południowoindyjskiego języka telegu. Jego pojawienie się w smartfonie powoduje awarię aplikacji wiadomości – informuje Bitdefender. Znak został celowo umieszczony w wiadomości na Twitterze, WhatsApp, Instagramie oraz Facebooku. Twitter filtrował tego typu wiadomości automatycznie je blokując.
Według Bitdefender jeden ze specjalistów twierdzi, że można także doprowadzić do awarii aplikacji sieciowej macOS, jeśli zostanie stworzony hotspot zawierający feralny symbol.
– Użytkownicy urządzeń z systemem iOS oraz macOS znają już tego typu przypadki. W 2013 roku okazało się, że komputery i smartfony mogą być uszkodzone przez ciąg znaków arabskich, natomiast w 2015 roku atak „Skuteczna Moc” sprawiał, że za pomocą sekwencji znaków programista mógł zdalnie uruchomić ponownie iPhone’a. W zeszłym miesiącu wykryto także szkodliwy link znany jako „błąd ChaiOS”, który powodował awarie urządzeń wyposażonych w ten system – informuje Mariusz Politowicz, certyfikowany inżynier rozwiązań Bitdefender w Polsce.
Apple wprowadziło poprawki do wspomnianych luk. Użytkownicy, którzy nie są w stanie usunąć wiadomości posiadających symbol Unicode, muszą poczekać na kolejną aktualizację systemu. Producent oprogramowania zablokował także możliwość wysyłania tego znaku w wiadomościach.
