The Exchange Online security controls organizations keep getting wrong

Help Net Security

In a recent interview, Scott Schnoll, a Microsoft MVP for Exchange, discussed common mistakes organizations make regarding security controls in Exchange Online. He emphasized the importance of understanding the Shared Responsibility Model, where Microsoft manages cloud security while organizations are responsible for their data and configurations. Schnoll pointed out that legacy protocols like SMTP AUTH often remain enabled due to dependencies on older systems, which can create vulnerabilities. He also identified critical controls that are frequently overlooked, such as Conditional Access and Privileged Identity Management (PIM), and noted the gaps in audit logs that can hinder effective monitoring. Organizations need to take immediate action to adjust default settings and implement better security practices to protect their environments.

Vidar infostealer evolves, uses image files for stealthy attacks

SCM feed for Latest

The Vidar infostealer has adapted its tactics to launch stealthy attacks by using social engineering techniques. Recent campaigns have taken advantage of a leak related to Claude Code by creating fake GitHub repositories that trick users into downloading malicious payloads disguised as legitimate image files. This approach allows attackers to bypass some traditional security measures, making it harder for users to detect the threat. Those who download the infected files could have their personal data stolen, including sensitive information and credentials. As this method becomes more prevalent, users must be cautious about the sources of their downloads and verify the authenticity of repositories before accessing them.
