Projekt \u00c5ben Wireless Link<\/a><\/noindex>, der analyserer Apples propriet\u00e6re tr\u00e5dl\u00f8se protokoller, den<\/a><\/noindex> p\u00e5 USENIX-konferencen 2019 en rapport<\/a><\/noindex> med en analyse af s\u00e5rbarheder i Apples tr\u00e5dl\u00f8se protokoller (findes muligheder for at udf\u00f8re MiTM-angreb for at \u00e6ndre filer sendt mellem enheder, DoS-angreb for at blokere interaktioner mellem enheder og for\u00e5rsage enhederne til at h\u00e6nge, samt brug af AirDrop til identificering og sporning af brugere). I l\u00f8bet af den udf\u00f8rte unders\u00f8gelse blev der forberedt \u00e5bne implementationer af protokollen AWDL (Apple Wireless Direct Link) og teknologien AirDrop<\/a><\/noindex>, hvor detaljer er hentet som f\u00f8lge af reverse engineering.<\/p>\n

Implementeringen af AWDL er skrevet i C-sprog og offentliggjort som en Linux-applikation owl<\/a><\/noindex> (Open Wireless Link), der bruger Netlink API til at udf\u00f8re Wi-Fi-specifikke operationer, som kanalskift. Integration med netv\u00e6rksstakken sker via et virtuelt netv\u00e6rksinterface, der muligg\u00f8r, at IPv6-supporterende applikationer kan bruge AWDL-protokollen uden at \u00e6ndre koden. Drift er mulig p\u00e5 netv\u00e6rkskort, der underst\u00f8tter aktiv overv\u00e5gningsmode, som tillader indspr\u00f8jtning af rammer (f.eks. underst\u00f8ttet i Atheros AR9280).<\/p>\n

AWDL-protokollen er grundlaget for Apples tr\u00e5dl\u00f8se teknologier, der bruges til at organisere direkte interaktion mellem enheder uden forudg\u00e5ende ops\u00e6tning og parring. Tjenesten AirDrop, som muligg\u00f8r filoverf\u00f8rsel via Wi-Fi og Bluetooth, fungerer ogs\u00e5 p\u00e5 baggrund af AWDL. De komponenter, som forskerne har forberedt til AirDrop, er skrevet i Python og tilg\u00e6ngelige i projektet OpenDrop<\/a><\/noindex>. Koden for owl og OpenDrop er offentliggjort under GPLv3-licensen.<\/p>\n

OpenDrop tilbyder et kommandolinjegr\u00e6nseflade, der muligg\u00f8r filoverf\u00f8rsel mellem enheder via Wi-Fi. P\u00e5 protokolniveau er implementationen helt kompatibel med Apple-enheder, hvilket muligg\u00f8r interaktion mellem Linux-baserede systemer og enheder med iOS og macOS. Filoverf\u00f8rsler tillades kun til Apple-enheder, der er i en tilstand med ubegr\u00e6nset opdagelse af andre brugere, da selektiv opdagelse og sending via kontaktbogen kr\u00e6ver digital signaturverifikation fra Apple. <\/p>\n
