@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: Cisco Releases Security Advisory for Authentication Bypass Vulnerability in Meeting Server Client Description: Cisco has released a security advisory for Cisco Meeting Server to address CVE-2016-6445, an authentication bypass vulnerability. CVE-2016-6445 manifests as a flaw in the Extensible Messaging and Presence Protocol (XMPP) service of Cisco Meeting Server and is triggered due to the XMPP service "incorrectly processing a deprecated authentication scheme." This vulnerability "could allow an unauthenticated, remote attacker to masquerade as a legitimate user." Cisco has released a software update to address this vulnerability. Reference: https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20161012-msc
Title: VeraCrypt Releases Update Addressing Security Vulnerabilities Identified by QuarksLab Description: VeraCrypt has released an update for its open source, on-the-fly disk encryption software to address security vulnerabilities QuarksLab identified along with other bugs that have been discovered. QuarksLab recently audited VeraCrypt to identify security vulnerabilities and, as a result of the audit, a total of 26 vulnerabilities were discovered. Eight of the vulnerabilities are rated "Critical" while three are rated "Medium" severity. The remaining 15 vulnerabilities are "Low" severity or "Informational" concerns. VeraCrypt 1.19 addresses the vast majority of the vulnerabilities identified by QuarksLab. However, some issues have not yet been fixed due to the "high complexity for the proposed fixes." Workarounds have been identified for those issues. Reference: https://ostif.org/the-veracrypt-audit-results/ https://veracrypt.codeplex.com/wikipage?title=Release%20Notes
Title: Researcher Discloses Left Over Factory Debugging Feature (Dubbed "Pork Explosion") in Foxconn-manufactured Phones Description: Security Researcher Jon "jcase" Sawyer has disclosed the presence of a left over factory debugging feature in Foxconn-manufactured Android phones. Dubbed "Pork Explosion" (as a jab at the silly nature of naming vulnerabilities), the left over debugging feature is a backdoor "in the apps bootloader provided by Foxconn." An attacker with physical access to the device could "gain a root shell, with selinux disabled through usb." jcase has reached out to Nextbit and the Android Security team to address this vulnerability and Nextbit has released a fix for their affected phones.
