A security researcher has figured out a way to dump a user's unencrypted plaintext Microsoft Azure credentials from Microsoft's new Windows 365 Cloud PC service using Mimikatz. On August 2nd, Microsoft launched their Windows 365 cloud-based desktop service, allowing users to rent Cloud PCs and access them via remote desktop clients or a browser.
A day after the August 2021 Patch Tuesday, Microsoft has released an out-of-band security advisory acknowledging the existence of yet another Print Spooler vulnerability. Microsoft says that CVE-2021-36958 is a remote code execution vulnerability exists when the Windows Print Spooler service improperly performs privileged file operations.
Ransomware operators such as Magniber and Vice Society are actively exploiting vulnerabilities in Windows Print Spooler to compromise victims and spread laterally across a victim's network to deploy file-encrypting payloads on targeted systems. "Multiple, distinct threat actors view this vulnerability as attractive to use during their attacks and may indicate that this vulnerability will continue to see more widespread adoption and incorporation by various adversaries moving forward," Cisco Talos said in a report published Thursday, corroborating an independent analysis from CrowdStrike, which observed instances of Magniber ransomware infections targeting entities in South Korea.
