Schon der Umstand, "dass eine betroffene Person infolge eines Verstoßes gegen die DSGVO befürchtet, dass ihre personenbezogenen Daten durch Dritte missbräuchlich verwendet werden könnten, kann einen 'immateriellen Schaden' darstellen", heißt es in dem Urteil, das am 14. Dezember 2023 veröffentlicht wurde. --------------------------------------------- https://www.golem.de/news/urteil-des-eugh-datenleck-betroffene-koennten-doc… ∗∗∗ Reverse, Reveal, Recover: Windows Defender Quarantine Forensics ∗∗∗ --------------------------------------------- Windows Defender (the antivirus shipped with standard installations of Windows) places malicious files into quarantine upon detection. Reverse engineering mpengine.dll resulted in finding previously undocumented metadata in the Windows Defender quarantine folder that can be used for digital forensics and incident response. Existing scripts that extract quarantined files do not process this metadata, even though it could be useful for analysis. Fox-IT’s open-source digital forensics and incident response framework Dissect can now recover this metadata, in addition to recovering quarantined files from the Windows Defender quarantine folder. --------------------------------------------- https://blog.fox-it.com/2023/12/14/reverse-reveal-recover-windows-defender-… ∗∗∗ Mobile Sicherheit.

Letztlich liegt es an Ihnen, den für Sie bestmöglichen Kompromiss zwischen Funktion, Komfort, Sicherheit und Privatsphäre zu finden. Die vorliegende Broschüre möchte Ihnen dabei helfen. --------------------------------------------- https://www.nis.gv.at/dam/jcr:8165f553-2769-4553-91c8-4b117c752f56/mobile_s… ∗∗∗ Ransomware: AlphV meldet sich zurück, Aufruhr in der Szene ∗∗∗ --------------------------------------------- In der Ransomware-Szene rumort es: Gruppen versuchen, einander Mitglieder abspenstig zu machen, ein Geldwäscher geht ins Netz und Betrüger betrügen einander. --------------------------------------------- https://www.heise.de/-9574446 ∗∗∗ Amazon-Händler:innen wollen über Telegram-Gruppen Bewertungen kaufen? Machen Sie nicht mit! ∗∗∗ --------------------------------------------- Auf Telegram gibt es Kanäle, die gratis Amazon-Produkte versprechen. Die Idee dahinter: Sie suchen sich ein Produkt aus, bestellen es über Ihren privaten Amazon-Account, schreiben eine 5-Sterne-Bewertung und bekommen als Dankeschön das Geld über PayPal zurückerstattet. Mit dieser Masche kaufen sich Marketplace-Händler:innen Bewertungen, um besser gerankt zu werden – eine nicht legale Praktik. --------------------------------------------- https://www.watchlist-internet.at/news/amazon-haendlerinnen-wollen-ueber-te… ∗∗∗ Protecting the enterprise from dark web password leaks ∗∗∗ --------------------------------------------- The trade in compromised passwords in dark web markets is particularly damaging.
