Warum schalten Schwerverbrecher ihr Handy nachts aus? BFU vs. AFU - der Unterschied, der ueber Verurteilung oder Freispruch entscheiden kann Was erfahrene Kriminelle ueber Handyforensik wissen - und was die meisten Beschuldigten nicht ahnen: Der Zeitpunkt, zu dem die Polizei dein Smartphone sicherstellt, ist forensisch entscheidend. In diesem Video erklaere ich als Strafverteidiger, was hinter den Begriffen BFU (Before First Unlock) und AFU (After First Unlock) steckt - und warum das fuer jedes Strafverfahren, in dem ein Handy beschlagnahmt wird, hochrelevant ist. Was ist BFU und AFU? BFU beschreibt den Zustand eines Smartphones nach einem Neustart, bevor der Passcode erstmals eingegeben wurde. In diesem Zustand sind die Verschluesselungsschluessel nicht im Arbeitsspeicher - das Geraet ist fuer forensische Tools wie Cellebrite UFED oder MSAB XRY weitgehend gesperrt. AFU dagegen bezeichnet den Zustand nach der ersten Entsperrung: Die Schluessel verbleiben aktiv im RAM, auch wenn der Bildschirm gesperrt ist. Im AFU-Zustand koennen Ermittler erheblich mehr Daten extrahieren - Nachrichten, Fotos, App-Inhalte, Kommunikation ueber verschluesselte Messenger. Handybeschlagnahme im Strafverfahren - was Beschuldigte wissen muessen Als auf Strafverteidigung spezialisierte Kanzlei begleiten wir Mandate in allen Phasen eines Strafverfahrens - vom Ermittlungsverfahren bis zur Revision. Handyforensik gehoert heute zu den zentralen Beweismitteln in Wirtschaftsstrafsachen, Betaeubungsmittelverfahren, Staatsschutzverfahren und nahezu allen Bereichen des Strafrechts. Wir kennen die forensischen Methoden, die Ermittlungsbehoerden einsetzen - BFU/AFU, Full File System Extraction, AFU-Angriffe via Cellebrite Premium, Checkm8-Exploits - und wir kennen die rechtlichen Grenzen dieser Massnahmen. Was ist zulaessig? Was unterliegt einem Beweisverwertungsverbot? Wann ist die Beschlagnahme rechtswidrig? Das sind die Fragen, die wir fuer unsere Mandanten klaeren. Forensische Auswertung, digitale Beweise, Handybeschlagnahme: Das ist kein Nischenthema - das ist die Realitaet moderner Strafverteidigung. Und wir beherrschen sie. Inhalte dieses Videos • Was bedeutet BFU (Before First Unlock) forensisch? • Was bedeutet AFU (After First Unlock) - warum sind mehr Daten auslesbar? • Wie arbeiten Cellebrite UFED und vergleichbare Tools? • Warum ist der Zeitpunkt der Sicherstellung taktisch entscheidend? • Rechtsgrundlagen: Was darf die Polizei - was nicht?
