@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
c
Title: Google Releases Monthly Security Bulletin for Android Description: Google has released its monthly security bulletin for Android and Nexus devices. As with other Android and Nexus security bulletins Google has released, there are two patch levels that will be made available for manufacturers and consumers. In total, 75 vulnerabilities were patched with 11 being classified "critical", 44 classified "high", and 20 classified "moderate". All vulnerabilities classified "critical" are privilege escalation flaws that could allow an application to execute code with kernel-level privilege and force the user to reflash the operating system if a device becomes compromised. Nexus devices will have a security update available for download on December 5th. Other devices should receive an update from the manufacturer as long as the device is currently supported. Reference: https://source.android.com/security/bulletin/2016-12-01.html Snort SID: Detection pending release of vulnerability information
Title: "Backdoor" in Sony IPELA Engine IP Camera Fixed Description: Researchers have identified what appears to be a "backdoor" in Sony IPELA Engine IP Cameras. This undocumented functionality was discovered via identifying a hardcoded password hash in the firmware and a mechanism to enable Telnet remotely via a specifically formatted HTTP request. While Sony has addressed the issue by releasing a firmware update, they have not commented on the nature of the undocumented functionality. Reference: http://blog.sec-consult.com/2016/12/backdoor-in-sony-ipela-engine-ip-cameras.html
Title: Buffer Overflow Vulnerability Identified in BSD libc Description: Researchers have identified a buffer overflow vulnerability in BSD libc. CVE-2016-6559 manifests due to "improper bounds checking of the obuf variable in the link_ntoa() function in linkaddr.c" and "may allow an attacker to read or write from memory". The impact of this vulnerability is not fully know as the "impact and severity depends on the method of exploit and how the library is used by applications." BSD libc has been updated to address this flaw. Note that this affects FreeBSD, OpenBSD, and Darwin (Apple macOS). Other distributions may be affected.
