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

Title: OpenSSL Releases Security Advisories To Address Critical and High Severity Vulnerabilities
Description: The OpenSSL Team has released a pair of security advisories to address several high severity vulnerabilities and one critical vulnerability. The first advisory, which was released on 2016-09-22, addressed 15 high, medium, and low severity vulnerabilities, including a mitigation for the SWEET32 attack on older block cipher algorithms. The second advisory, released on 2016-09-26, addressed a critical vulnerability pertaining to the patch for CVE-2016-6307, which was addressed in the first advisory. The critical flaw could result in a denial-of-service or lead to arbitrary code execution. Users and developers who have installed or applied OpenSSL 1.1.0a should immediately update to 1.1.0b.

Title: Researchers Discover Weakness in Apple iOS 10 Backup Password Function Making It Easier to Brute Force
Description: Researchers have identified an issue in the Apple iOS 10 backup protection mechanism that could make it easier for attacker brute force the password to an iOS 10 backup. According to researchers at Elcomsoft, Apple introduced a new mechanism that "skips certain security checks, allowing [attackers] to try passwords approximately 2,500 times faster compared to the old mechanism used in iOS 9 and older." Apple has issued a statement to ThreatPost acknowledging the problem and promising to address the issue in a forthcoming update.
