@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
Oracle Releases Out of Band Security Advisory for Java Vulnerability Patched in 2013 Description: Oracle has released an out-of-band security advisory for a Java vulnerability that was originally reported in 2013 and patched back then. Since the original release of the patch for CVE-2013-5838, new information detailing how the patch was incomplete and could still allow an attacker to remotely execute code has been made public. In response to this new information, Oracle has fixed the broken patch and has release an updated version of Java that addresses the issue. Per Oracle's website, "Oracle Java SE 7 Update 97, and 8 Update 73 and 74 for Windows, Solaris, Linux, and Mac OS X are affected." Users are advised to update their Java installations. Reference: http://www.oracle.com/technetwork/topics/security/alert-cve-2016-0636-2949497.html http://seclists.org/fulldisclosure/2016/Mar/31 Snort SID: 38338-38339
Title: VNew Server-Side Ransomware Variant (Samas/Samsam) Hitting Hospitals Description: Researchers have identified a ransomware variant that appears to be currently targeting hospitals in the United States. Known as Samas/Samsam, this ransomware variant is unique in that instead of targeting individual users through phishing attacks or via exploit kits, adversaries are compromising systems via external facing JBoss servers that are vulnerable to compromise and moving laterally within the network to compromise additional systems. Multiple threat intelligence organizations have reported on this ransomware variant with detection being made available to detect and mitigate this threat. Reference: https://threatpost.com/new-server-side-ransomware-hitting-hospitals/117059/ Snort SID: 18794, 21516-21517, 24342-24343, 24642, 29909, 38279-38280, 38304 ClamAV: Win.Trojan.Samas
Title: Multiple Cross-site Scripting (XSS) Vulnerabilities in Zen Cart Patched Description: Researchers at Trustwave have identified multiple XSS vulnerabilities in Zen Cart, a popular online shopping cart software package. Trustwave responsibly disclosed these vulnerabilities to Zen Cart and worked to ensure all vulnerabilities were properly patched before disclosure. Zen Cart has release Zen Cart 1.5.5 to address these vulnerabilities. Additionally, Zen Cart has made available the patches to address the flaws if patching is not immediately possible. Reference: Reference: https://www.zen-cart.com/showthread.php?219732-Trustwave-Security-report-Patch-Included https://www.trustwave.com/Resources/SpiderLabs-Blog/TWSL2016-006--Multiple-XSS-Vulnerabilities-reported-for-Zen-Cart/ Snort SID: Detection pending release of vulnerability information
