Newsletters: @RISK

@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 VULNERABILITY RESEARCH TEAM

Title: Major Remote Code Execution Flaw With Android Disclosed
Description: A major flaw within an Android core media library has been disclosed by researchers at Zimperium. Dubbed Stagefright, the flaw within the library is due to the a coding deficiency where specially crafted MMS files could result in remote code execution on the target device. Google has patched the vulnerability within their code base. However, users will remain at risk until OEMs and carriers push out the patch. Users are advised to manually disable auto-fetching of MMS messages as a workaround to prevent getting compromised.

Snort SID: Detection pending release of vulnerability information

Title: Cross Site Scripting (XSS) Vulnerability Within WordPress Patched
Description: WordPress has released an advisory and an updated version of its blogging platform software to address a cross site scripting (XSS) vulnerability. The flaw could allow users with "the Contributor or Author role to compromise" a WordPress installation. WordPress installation administrators are strongly encouraged to update to the latest version immediately to reduce the possibility of compromise.
