@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: Apple Releases Emergency iOS Update to Address Zero-Day Vulnerabilities Being Exploited in the Wild Description: Apple has released an emergency security update for iOS after it was discovered that three zero-day vulnerabilities were being exploited in the wild. These three vulnerabilities when used together could be used to achieve remote code execution with kernel level privileges. Citizen Labs and Lookout, research firms that privately disclosed the vulnerabilities to Apple, state that these vulnerabilities were used to install surveillance software on the phones of human rights activists. Users are advised to patch immediately. Reference: https://support.apple.com/en-us/HT207107 https://citizenlab.org/2016/08/million-dollar-dissident-iphone-zero-day-nso-group-uae/ Snort SID: Detection pending release of vulnerability information
Title: VMware Addresses Vulnerability in VMware Identity Manager and vRealize Automation Description: VMware has released a security update for Identity Manager and vRealize Automation to address CVE-2016-5335 and CVE-2016-5336. CVE-2016-5335 is a local privilege escalation vulnerability within Identity Manager and affects Identity Manager 2.x and vRealize 7.0.x. CVE-2016-5336 is a remote code execution vulnerability in vRealize Automation 7.0.x. that could allow an attacker to "access to a low-privileged account on the appliance." Note that workarounds are available for CVE-2016-5336. Reference: http://www.vmware.com/security/advisories/VMSA-2016-0013.html Snort SID: Detection pending release of vulnerability information
