A noteworthy aspect that sets it apart from other Magecart campaigns is that the hijacked sites further serve as "makeshift" command-and-control (C2) servers, using the cover to facilitate the distribution of malicious code without the knowledge of the victim sites. --------------------------------------------- https://thehackernews.com/2023/06/magento-woocommerce-wordpress-and.html ∗∗∗ Storing Passwords - A Journey of Common Pitfalls ∗∗∗ --------------------------------------------- [..] we recently discovered a vulnerability in the web interface of STARFACE PBX allowing login using the password hash rather than the cleartext password (see advisory). We want to use this as an opportunity to discuss how we analyse such login mechanisms and talk about the misconceptions in security concepts that result in such pitfalls along the way. --------------------------------------------- https://blog.redteam-pentesting.de/2023/storing-passwords/ ∗∗∗ Big-Data-Unternehmen Splunk schließt teils kritische Sicherheitslücken ∗∗∗ --------------------------------------------- Der Big-Data-Spezialist Splunk korrigiert in der gleichnamigen Software zahlreiche Sicherheitslücken, die teils als kritisches Risiko eingestuft werden. --------------------------------------------- https://heise.de/-9164194 ∗∗∗ Gigabyte Rolls Out BIOS Updates to Remove Backdoor From Motherboards ∗∗∗ --------------------------------------------- Gigabyte has announced BIOS updates that remove a recently identified backdoor feature in hundreds of its motherboards. --------------------------------------------- https://www.securityweek.com/gigabyte-rolls-out-bios-updates-to-remove-back… ∗∗∗ Kriminelle missbrauchen Spenden-Funktion von PayPal ∗∗∗ --------------------------------------------- Aktuell beobachten wir, dass Fake-Shops PayPal-Zahlungen mit der Funktion „Geld spenden“ abwickeln.
