Recently Patched Vulnerabilities In Microsoft Azure Stack Could Have Allowed Server Takeovers



Unfortunately, the victim organization did not keep any logs or forensic artefacts from their Exchange server in December 2020, which would have allowed Darktrace to ascertain the exploit of the zero-day. However, there is circumstantial evidence suggesting that these Exchange server vulnerabilities were abused.




Recently Patched Vulnerabilities in Microsoft Azure Stack Could Have Allowed Server Takeovers



85. After listening to Microsoft's proposal, Barksdale had two main questions: First, where would the line between platform (Microsoft's exclusive domain) and applications (where Netscape could continue to function) be situated? Second, who would get to decide where the line would lie? After all, the attractiveness of a special relationship with Microsoft depended a great deal on how much room would remain for Netscape to innovate and seek profit. The Microsoft representatives replied that Microsoft would incorporate most of the functionality of the current Netscape browser into the Windows 95 platform, perhaps leaving room for Netscape to distribute a user-interface shell. Where Netscape would have the most scope to innovate would be in the development of software "solutions," which are applications (mainly server- based) focused on meeting the needs of specific types of commercial users. Since such applications are already minutely calibrated to the needs of their users, they do not present platforms for the development of more specific applications. Although the representatives from Microsoft assured Barksdale that the line between platform and solutions was fixed by a collaborative decision-making process between Microsoft and its ISV partners, those representatives had already indicated that the space Netscape would be allowed to occupy between the user and Microsoft's platform domain was a very narrow one. Simply put, if Navigator exposed APIs that competed for developer attention with the Internet-related APIs Microsoft was planning to build into its platform, Microsoft would regard Netscape as a trespasser on its territory.

Willkommen in der Gruppe zu unserer Aufführung "Rasmus geht ...

Neu!

Die Schule der magischen Tiere

Theaterstück für eine Schulklasse nach dem Buch von Margit Auer

Im Kinderhaus der Brunsviga in Braunschweig haben wir im Herbst 2022 das Theaterstück "Die Schule der magischen Tiere" mit Kindern aufgeführt, und eine tolle Aufführung mit fast 300 Besuchern zum Abschluss des Aufführungsworkshops erleben dürfen. Wir bemühen uns weiter darum, hier mehr Fotos aus der Aufführung zeigen zu dürfen, und bereiten zumindest einen weiteren Aufführungsworkshop mit diesem Stück vor. Interessierte Schulen oder andere Einrichtungen für Kinder können sich einfach direkt an uns wenden!
