@RISK provides a reliable weekly summary of (1) newly discovered attack vectors, (2) vulnerabilities with active new exploits, (3) insightful explanations of how recent attacks worked, and other valuable data
A key purpose of the @RISK is to provide the data that will ensure that the 20 Critical Controls (the US and UK benchmark for effective protection of networked systems) continue to be the most effective defenses for all known attack vectors. But since it is also valuable for security practitioners, SANS is making it available to the 145,000 security practitioners who have completed SANS security training and others at their organizations who hope to stay current with the offensive methods in use.

SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP
Title: PHPMailer and SwiftMailer Updated to Resolve Code Execution Flaw After First Patch Deemed Insufficient Description: PHPMailer and SwiftMailer have released updates to address a vulnerability that was identified by Dawid Golunski of Legal Hackers. PHPMailer and SwiftMailer had released an update to address CVE-2016-10033, a arbitrary code execution vulnerability that could be exploited remotely. However, it was found that the patch was insufficient. In response, PHPMailer and Swiftmailer released another update to address CVE-2016-10045. Administrators who manage servers or applications that relied on these libraries should update their systems.
