@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.

============================================================NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP
Title: Remotely Exploitable 0-Day Impacts NETGEAR WNR2000 Routers Description: Researcher discovers several vulnerabilities that could result in remote code execution capabilities in Netgear WNR2000 routers. The vulnerabilities are only exploitable over the LAN by default. However, researcher was able to find more than 10,000 vulnerable routers that have remote administration enabled via Shodan. The vulnerabilities include information leakage, command execution, and a stack buffer overflow that could allow remote code execution. Reference: http://kb.netgear.com/000036549/Insecure-Remote-Access-and-Command-Execution-Security-Vulnerability
Title: Critical PHPMailer Flaw leaves Millions of Websites Vulnerable to Remote Exploit Description: Researcher discovers vulnerabilities in PHPMailer that could result in remote code execution capabilities. PHPMailer is widely used in open source applications such as Word Press and Drupal. The vulnerability, CVE-2016-10033, can be exploited by an attacker using website components that send email such as contact/feedback and registration forms. The attacker is able to execute code provided in the email on the local system. Reference: http://legalhackers.com/advisories/PHPMailer-Exploit-Remote-Code-Exec-CVE-2016-10033-Vuln.html
