@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
TGoogle Patches Several Major Vulnerabilities in January Android Security Bulletin Description: Google has released its January Security Bulletin for Nexus devices addressing several critical vulnerabilities with Android. One notable vulnerability addressed this month is a remote code execution vulnerability in Mediaserver that manifests as a failure to properly handle specially crafted media files. Mediaserver is core part of Android that is used to process and decode media files, such as MMS and browser playback of media. Other vulnerabilities that were patched include privilege escalation flaws, information disclosure flaws, and a denial-of-service flaw. Updating to build LMY49F or later and/or Android 6.0 with Security Patch Level of January 1, 2016 addresses these flaws. In addition, partners have been notified about this vulnerabilities and provided updates to address these flaws in respective firmware releases. Reference: https://source.android.com/security/bulletin/2016-01-01.html Snort SID: Detection pending release of vulnerability information
Title: Comcast XFINITY Home Security Systems Found to Improperly Handle Wireless Communication Disruptions/Failures with Sensors Description: Researchers at Rapid7 have found that the Comcast XFINITY Home Security System fails to properly handle communication disruptions between the base station and sensors. The base station's software fails to handle communication disruptions by not triggering an alert should sensors cease communicating, thereby potentially reporting an incorrect state (such a door reporting as "closed" when it is actually "open"). An attacker who disrupts communications over the 2.4 GHz radio frequency band to prevent sensors from communicating with the base station could exploit this flaw to enter a domicile and avoid triggering Home Security system alarm events (even in an "armed" state). Currently, no known workaround or mitigate to address this vulnerability is known or available. Reference: https://community.rapid7.com/community/infosec/blog/2016/01/05/r7-2015-23-comcast-xfinity-home-security-system-insecure-fail-open
Title: Cisco Jabber Client Found Vulnerable to STARTTLS downgrade attack Description: Researchers at Synacktiv have found that the Cisco Jabber client is vulnerable to a STARTTLS downgrade attack. The vulnerability manifests due to a failure to validate if a XMPP connection has been established over TLS. A man-in-the-middle attacker could exploit this flaw and tamper with the XMPP connection to avoid TLS negotiation, causing the client to establish a XMPP connection over cleartext. Cisco has released a security advisory and updated software to address this vulnerability. Reference: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20151224-jab
