@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: Meltdown, Spectre-like flaws found in chips

Description: Microsoft and Google have disclosed a new vulnerability, dubbed Speculative Store Bypass Variant 4 that impacts Intel, AMD and ARM processors. If exploited, an attacker could potentially access information that was meant to be hidden. Speculative Store Bypass Variant 4 is similar to the Meltdown and Spectre vulnerabilities from earlier in the year, in that it is a new kind of attack on processors.
