@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: Latest Adobe Flash 0-day Flaw Active Exploited in Nuclear, Neutrino, and Magnitude Exploit Kits Description: The most recent Flash zero-day vulnerability that was disclosed and and patched by Adobe is currently being actively exploited in three exploit kits. The Nuclear, Neutrino, and Magnitude exploit kits have now incorporated exploits for CVE-2016-4117, targeting vulnerable versions of Flash. As a reminder, users who do not require Flash are strongly encouraged to remove it from their systems. For users who need Flash and/or who do not have the ability to uninstall it, disabling Flash within the browser is strongly recommended to reduce the risk of compromise. Reference: http://malware.dontneedcoffee.com/2016/05/cve-2016-4117-flash-up-to-2100213-and.html Snort SID: 38874-38875
Title: Magneto Patches Several Security Flaws in Enterprise and Community Editions Description: Magneto has patched several security flaws in its flagship eCommerce platform. The two most severe flaws addressed in the latest patch are remote code execution vulnerabilities whereby an unauthenticated attacker could either execute PHP code using REST or SOAP APIs or forcefully reinstall the application. Magneto has addressed these two critical flaws as well as four other vulnerabilities in its latest version, 2.0.6. Administrators are strongly encouraged to updated their Magneto installations to the latest version. Reference: https://magento.com/security/patches/magento-206-security-update http://netanelrub.in/2016/05/17/magento-unauthenticated-remote-code-execution/ Snort SID: Detection pending release of vulnerability information
