Microsoft Defender Application Guard protects your networks and data from malicious applications running in your web browser, but you must install and activate it first. In a previous article, we noted that many of the security features listed as absolute requirements for a successful Windows 11 installation are already available as options in Windows 10, you just have to turn them on manually.
Denoted CVE-2021-36934, this one has variously been nicknamed HiveNightmare and SeriousSAM. The moniker HiveNightmare comes from the fact that Windows stores its registry data in a small number of proprietary database files, known in Microsoft jargon as hives or hive files. These hive files include a trio called SAM, SECURITY and SYSTEM, which between them include secret data including passwords and security tokens that regular users aren't supposed to be able to access.
Today, researchers at ReversingLabs have disclosed their findings on two malicious npm packages that secretly steal passwords from your Chrome web browser. "We have contacted NPM to take the package down. We are still waiting on their security team to respond," ReversingLabs' chief software architect and co-founder, Tomislav Pericin told BleepingComputer in an email interview.
A highly popular malware for stealing information from Windows systems has been modified into a new strain called XLoader, which can also target macOS systems. The connection between the two malware pieces was confirmed after a member of the community reverse-engineered XLoader and found that it had the same executable as Formbook.
"An elevation of privilege vulnerability exists because of overly permissive Access Control Lists on multiple system files, including the Security Accounts Manager database. An attacker who successfully exploited this vulnerability could run arbitrary code with SYSTEM privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. An attacker must have the ability to execute code on a victim system to exploit this vulnerability," Microsoft confirmed. The vulnerability stems from the fact that non-administrative users can read the vulnerable host's sam, system, and security Windows Registry hive files.
Microsoft has shared a workaround for a Windows 10 zero-day vulnerability that can let attackers gain admin rights on vulnerable systems and execute arbitrary code with SYSTEM privileges. "An elevation of privilege vulnerability exists because of overly permissive Access Control Lists on multiple system files, including the Security Accounts Manager database," Microsoft explains in a security advisory published on Tuesday evening.

Recent builds of Windows 10, and the preview of Windows 11, have a misconfigured access control list for the Security Account Manager, SYSTEM, and SECURITY registry hive files. You may think you're safe because your Windows PC doesn't have a suitable VSS shadow copy, yet there are ways to end up quietly creating one and put your machine at risk.
With Windows 11, Microsoft is integrating the Microsoft Teams chatting feature into the Windows Taskbar. Microsoft Teams Chat feature is based on Microsoft Teams desktop client and Microsoft is basically extending Teams capability by bringing the dedicated button right to your taskbar.
