I Chrome 76 st\u00e4ngdes en s\u00e4kerhetslucka<\/a><\/noindex> i implementeringen av FileSystem API, som m\u00f6jliggjorde att ett webbl\u00e4sarprogram kunde uppt\u00e4cka anv\u00e4ndning av inkognitol\u00e4ge. Fr\u00e5n och med Chrome 76 blockerar webbl\u00e4saren inte l\u00e4ngre \u00e5tkomsten till FileSystem API, vilket tidigare anv\u00e4ndes som en indikator f\u00f6r inkognitol\u00e4get, utan ist\u00e4llet rensade de \u00e4ndringar som gjordes efter sessionen. Det visade sig att den nya implementeringen har<\/a><\/noindex> brister som g\u00f6r det m\u00f6jligt, precis som tidigare, att uppt\u00e4cka aktiviteten i inkognitol\u00e4get.<\/p>\n

Problemet \u00e4r att sessionen med FileSystem API i inkognitol\u00e4get \u00e4r tempor\u00e4r, och data sparas inte p\u00e5 disken utan h\u00e5lls i RAM-minnet. D\u00e4rf\u00f6r, genom att m\u00e4ta<\/a><\/noindex> tiden f\u00f6r data\u00f6verf\u00f6ring via FileSystem API och de avvikelser som uppst\u00e5r (vid sparande i RAM-minnet registreras konstanta egenskaper, medan f\u00f6rdr\u00f6jningarna \u00e4ndras vid skrivning till disk) kan man med ganska stor s\u00e4kerhet bed\u00f6ma om sidan visas i inkognitol\u00e4ge eller inte. Nackdelen med metoden \u00e4r den relativt l\u00e5nga processen f\u00f6r att m\u00e4ta avvikelser, som kan ta upp till en minut (demonstration<\/a><\/noindex>). <\/p>\n

Samtidigt finns det \u00e4nnu en ovett i Chrome 76, problem<\/a><\/noindex>som g\u00f6r det m\u00f6jligt att avg\u00f6ra aktiviteten av inkognitol\u00e4get baserat p\u00e5 bed\u00f6mning av de begr\u00e4nsningar som s\u00e4tts via API Quota Management<\/a><\/noindex>. F\u00f6r den tempor\u00e4ra lagringen som anv\u00e4nds i inkognitol\u00e4get s\u00e4tts andra gr\u00e4nser \u00e4n vid fullst\u00e4ndig lagring p\u00e5 disk.<\/p>\n

Kom ih\u00e5g att webbplatser som verkar enligt modellen f\u00f6r att erbjuda full tillg\u00e5ng via betalprenumeration (paywall) \u00e4r intresserade av att uppt\u00e4cka inkognitol\u00e4get. F\u00f6r att locka en ny publik erbjuder s\u00e5dana webbplatser nya anv\u00e4ndare under en tid fullst\u00e4ndig visning, vilket aktivt utnyttjas f\u00f6r att kringg\u00e5 paywall. Det enklaste s\u00e4ttet att f\u00e5 tillg\u00e5ng till betalt inneh\u00e5ll i s\u00e5dana system \u00e4r att anv\u00e4nda inkognitol\u00e4get, d\u00e4r webbplatsen tycker att anv\u00e4ndaren har \u00f6ppnat sidan f\u00f6r f\u00f6rsta g\u00e5ngen. Utgivare \u00e4r missn\u00f6jda med detta beteende, d\u00e4rf\u00f6r har de aktivt anv\u00e4nt den relaterade s\u00e4kerhetsluckan i FileSystem API f\u00f6r att kr\u00e4va att inkognitol\u00e4ge st\u00e4ngs av f\u00f6r fortsatt visning.<\/p>\n
