We are excited to announce the addition of scenario-based bounty awards to the Dynamics 365 and Power Platform Bounty Program and M365 Bounty Program. Through these new scenario-based bounty awards, we encourage researchers to focus their research on vulnerabilities that have the highest potential impact on customer privacy and security. Awards increase by up to 30% ($26,000 USD total) for eligible scenario submissions.

Megjelent a SANS és a Nemzetbiztonsági Szakszolgálat Nemzeti Kibervédelmi Intézet közös kiadványfolyamának 2022. márciusi száma, amely a három leggyakoribb közösségi média csalással foglalkozik, és ad tanácsokat a kezelésükhöz.

Summary Microsoft used the Spring Framework RCE, Early Announcement to inform analysis of the remote code execution vulnerability, CVE-2022-22965, disclosed on 31 Mar 2022. We have not to date noted any impact to the security of our enterprise services and have not experienced any degraded service availability due to this vulnerability.

Microsoft is excited to announce the addition of Exchange on-premises, SharePoint on-premises, and Skype for Business on-premises to the Applications and On-Premises Servers Bounty Program. Through this expanded program, we encourage researchers to discover and report high-impact security vulnerabilities to help protect customers. We offer awards up to $26,000 USD for eligible submissions.

Windows 10 made a lot of improvements in Kernel Address Space Layout Randomization (KASLR) that increases the cost of exploitation, particularly for remote code execution exploits. Many kernel virtual address space (VAS) locations including kernel stacks, pools, system PTEs etc. are randomized. A well-known exception to this is the KUSER_SHARED_DATA structure which is a page of memory that has always been traditionally mapped at a fixed virtual address in the kernel.

Microsoft is committed to partnering with and supporting women in security research. Whether it’s growing women early in their career, or connecting people with mentors, we want to be a part of the journey. Throughout Women’s History Month we intentionally sought opportunities to engage with women in security research. Whether at an intimate gathering of some of the most respected women in security research or engaging with women early in their career, it became obvious there just aren’t enough women in security research.

The security landscape is dynamic, changing often and as a result, attack surfaces evolve. MSRC receives a wide variety of cases spanning different products, bug types and exploit primitives. One particularly interesting primitive we see is an arbitrary kernel pointer read. These often happen when kernel mode code does not validate that pointers read from attacker-controlled input actually point to the user-mode portion of the Virtual Address Space (VAS).

Microsoft released a security update to address CVE-2022-23278 in Microsoft Defender for Endpoint. This important class spoofing vulnerability impacts all platforms. We wish to thank Falcon Force for the collaboration on addressing this issue through coordinated vulnerability disclosure. Cybercriminals are looking for any opening to tamper with security protections in order to blind, confuse, or often shut off customer defenses.
