@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: Major Vulnerability in ImageMagick Library Potentially Leading to Remote Code Execution Disclosed Description: A major vulnerability in ImageMagick that could lead to remote code execution has been disclosed to the public is under active exploitation in the wild. The flaw (CVE-2016-3714) manifests due to improperly handling images and can be exploited if the library is used to process user submitted images. Researchers have indicated that several image processing plugins utilize the ImageMagick library such as PHP, Ruby, and node.js. Mitigations to reduce the risk of compromise are available if patching is not an immediate viable option. Reference: https://imagetragick.com/ Snort SID: Detection pending
Title: OpenSSL Releases Security Advisory for Six Vulnerabilities Description: OpenSSL has released a security advisory to address six vulnerabilities within the open source crypto library. Two vulnerabilities are high severity with one issue (CVE-2016-2108) being a potential memory corruption issue while the other (CVE-2016-2107) is a padding oracle attack in AES-NI CBC MAC Check. The remaining four vulnerabilities are low-severity. OpenSSL has released an updated version of OpenSSL to address these issues. Users are advised to update their systems as patches for operating systems and software packages become available. Reference: https://www.openssl.org/news/secadv/20160503.txt Snort SID: Detection pending
Title: Google Releases Monthly Security Bulletin for Android; 40 Vulnerabilities Patched Description: Google has released their monthly security bulletin for the Android mobile operating system. This month's bulletin addresses 25 issues across 17 different components. The most critical issues addressed in this month's patch are in Mediaserver, Debuggerd, Qualcomm TrustZone, Qualcomm Wi-Fi Driver, NVIDIA Video Driver, and the Kernel which could result in remote code execution or privilege escalation. Google has released an over-the-air security update for Nexus devices. For other Android devices, Google has notified partners and will be releasing the source code for these patches.
