While the original attack vector was Print System Remote Protocol [MS-RPRN], the same attack delivered via Print System Asynchronous Remote Protocol [MS-PAR] does not require Windows server to be a domain controller, or Windows 10 machine to have UAC User Account Control disabled or PointAndPrint NoWarningNoElevationOnInstall enabled. --------------------------------------------- https://blog.0patch.com/2021/07/free-micropatches-for-printnightmare.html ∗∗∗ Another 0-Day Looms for Many Western Digital Users ∗∗∗ --------------------------------------------- Countless Western Digital customers saw their MyBook Live network storage drives remotely wiped in the past month thanks to a bug in a product line the company stopped supporting in 2015, as well as a previously unknown zero-day flaw. But there is a similarly serious zero-day flaw present in a much broader range of newer Western Digital MyCloud network storage devices that will remain unfixed for many customers who cant or wont upgrade to the latest operating system. --------------------------------------------- https://krebsonsecurity.com/2021/07/another-0-day-looms-for-many-western-di… ∗∗∗ Spam per Termineinladung: So schützen Sie sich! ∗∗∗ --------------------------------------------- Sie haben plötzlich im Lotto gewonnen.
