@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.

INTERESTING NEWS FROM AROUND THE SECURITY COMMUNITY


The security community continues to debate the validity of a story published by Bloomberg that states Chinese hackers may have installed tiny chips onto devices used in the U.S. that could be used to carry out cyber espionage. The companies named in the report, including Amazon and Apple, have so far denied that this happened.

Google plans to shut down its Google+ social media platform after it tried to cover up a data breach. The company chose to not disclose that thousands of users could have had their information stolen over the past three years, according to a report in the Wall Street Journal, which led it to shut down the site.
