W Chrome 76 zosta\u0142a ukryta<\/a><\/noindex> dziura w implementacji FileSystem API, kt\u00f3ra umo\u017cliwia\u0142a z web-aplikacji okre\u015blenie u\u017cycia trybu incognito. Zaczynaj\u0105c od Chrome 76, zamiast blokowa\u0107 dost\u0119p do FileSystem API, kt\u00f3re by\u0142o u\u017cywane jako znak aktywno\u015bci trybu incognito, przegl\u0105darka przesta\u0142a ogranicza\u0107 FileSystem API, ale czy\u015bci\u0142a wprowadzone zmiany po sesji. Okaza\u0142o si\u0119, \u017ce nowa implementacja ma<\/a><\/noindex> niedoci\u0105gni\u0119cia, kt\u00f3re pozwalaj\u0105, jak dawniej, okre\u015bla\u0107 aktywno\u015b\u0107 trybu incognito.<\/p>\n

Istot\u0105 problemu jest to, \u017ce sesja z FileSystem API w trybie incognito jest tymczasowa, a dane nie s\u0105 zapisywane na dysku i s\u0105 przechowywane w pami\u0119ci operacyjnej. W zwi\u0105zku z tym, mierz\u0105c<\/a><\/noindex> czas zapisywania danych przez FileSystem API i powstaj\u0105ce odchylenia (przy zapisywaniu w RAM ustala si\u0119 sta\u0142e cechy, podczas gdy przy zapisie na dysk op\u00f3\u017anienia si\u0119 zmieniaj\u0105), mo\u017cna do\u015b\u0107 pewnie oceni\u0107, czy przegl\u0105dana strona jest w trybie incognito, czy nie. Wad\u0105 metody jest do\u015b\u0107 d\u0142ugi proces pomiaru odchyle\u0144, kt\u00f3ry mo\u017ce trwa\u0107 oko\u0142o minuty (demonstracja<\/a><\/noindex>). <\/p>\n

Jednocze\u015bnie w Chrome 76 pozostaje niepoprawiona jeszcze jedna problem<\/a><\/noindex>, umo\u017cliwiaj\u0105ca ocen\u0119 aktywno\u015bci trybu incognito na podstawie oceny ustalanych ogranicze\u0144 przez API Zarz\u0105dzanie limitami<\/a><\/noindex>. Dla u\u017cywanego w trybie incognito tymczasowego magazynu ustalane s\u0105 inne limity ni\u017c w przypadku pe\u0142nego przechowywania na dysku.<\/p>\n

Przypomnijmy, \u017ce w okre\u015bleniu trybu incognito zainteresowane s\u0105 strony internetowe dzia\u0142aj\u0105ce na zasadzie oferowania pe\u0142nego dost\u0119pu za op\u0142at\u0105 (paywall). Aby przyci\u0105gn\u0105\u0107 now\u0105 publiczno\u015b\u0107, takie strony oferuj\u0105 nowym u\u017cytkownikom przez pewien czas demonstracyjny pe\u0142ny dost\u0119p, co jest aktywnie wykorzystywane do omijania paywall. Najprostszym sposobem uzyskania dost\u0119pu do p\u0142atnej tre\u015bci w takich systemach jest u\u017cycie trybu incognito, w kt\u00f3rym strona uwa\u017ca, \u017ce u\u017cytkownik otworzy\u0142 stron\u0119 po raz pierwszy. Takie zachowanie nie satysfakcjonuje wydawc\u00f3w, dlatego aktywnie wykorzystywali powi\u0105zan\u0105 z FileSystem API luk\u0119, aby wymusi\u0107 wy\u0142\u0105czenie trybu incognito w celu kontynuacji przegl\u0105dania.<\/p>\n
