@Risk: Security Alert
OUCH! Security Awareness
Case Leads DFIR Digest
Industrial Control Systems
Industrials & Infrastructure


@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: LastPass Addresses Security Flaw Identified by Researcher Tavis Ormandy
Description: LastPass has addressed a security flaw within the LastPass Firefox plugin, which was identified by Google Project Zero's Tavis Ormandy. Per the Project Zero bug, the LastPass Firefox plugin injects styling and event handlers into the web page "to create a privileged iframe." An attacker could have exploited this flaw to insert their own handler in a web page to "modify legitimate messages." LastPass has addressed the issue and pushed out an update for the Firefox plugin. Users can also manually update their plugins to ensure the patch is applied.

Title: Google Releases Monthly Android Security Bulletin
Description: Google has released their monthly Android security bulletin to address vulnerabilities within the mobile OS. This month's bulletin is divided into two patch levels to "provide Android partners with the flexibility" to address common Android components shared across all Android devices. In total, 102 vulnerabilities were addressed across both patch levels with 3 of them being Critical Mediaserver bugs that could allow arbitrary code execution. Another 3 dozen or so vulnerabilities within Qualcomm components were also addressed in the 2015-08-05 patch level.
