  • Researchers have discovered a worm-like vulnerability in Microsoft Teams platform that could allow attackers to take over an entire list of an organization’s accounts by sending links to image files. The vulnerability, affecting both desktop and web versions of the platform, has been patched by Microsoft.
  • Adobe has released emergency updates for three of its widely used products that patch dozens of newly discovered critical vulnerabilities. Affected software includes Adobe Illustrator, Adobe Bridge, and Magento e-commerce platform.
  • Sophos has published an emergency security update to fix an SQL injection vulnerability in its firewall product that is being actively exploited in the wild. Following successful exploitation, attackers employed a malware called Asnarok to steal usernames and other data used for remote access to the device.


Threat Intelligence Reports

  • The operators of the Shade ransomware, active since 2014, have announced the termination of their activity and published more than 750K decryption keys to be used by past victims. While the reasons for the termination are unclear, the decryption keys are authentic and functioning and a decryption tool has been published.
  • Researchers report of a sharp increase in the number of RDP brute-force attacks since mid-March due to remote working during the COVID-19 pandemic. This aligns with a Shodan report from earlier this month showing a 40% increase in exposed RDP endpoints.
