Dark Reading has written an article discussing how we can encourage employees to shift their mindset to become more security focused when online.

Action Recommended: Check if your On-Prem or Hybrid Microsoft Exchange Server is Still Vulnerable to ProxyNotShell and/or OWASSRF Exploitation

Despite repeated warnings to patch on-premises and hybrid Microsoft Exchange servers during the past couple of years, the number of vulnerable servers remains concerning.

AR-in-a-Box is described as “a comprehensive solution for cybersecurity awareness activities designed to meet the needs of public bodies, operators of essential services, and both large and small private companies.” The collection includes multiple guidelines and instructions covering the different aspects an organization needs to be aware of when organizing a cybersecurity awareness campaign, as well as an awareness quiz and game for use by employees.

Threat Awareness – New USB Malware Variant Utilizes Novel Method of Obfuscation

Palo Alto Networks published a blog discussing research by its Unit 42 of a newly discovered variant of PlugX malware. This variant has a few unique capabilities, including the ability to hide itself within a USB using a novel technique that’s effective on the current Windows OS and that can only be detected using specialized forensic tools. It then copies all Adobe PDF and Microsoft Word files from the attached machine and spreads to any other removable drives (e.g., floppy, thumb, or flash) connected to the system.
