@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: Vulnerabilities in Zoom meeting software could turn on Mac cameras
Description: Two vulnerabilities -- CVE-2019-13449 and CVE-2019-13450 -- in the Zoom remote could allow an attacker to use a malicious website to automatically start a Zoom meeting and look in on a user's Mac camera. While Zoom says it has mitigated the issue, users are also encouraged to ensure the Mac Zoom app is up to date and to disable the setting that allows Zoom to automatically turn on the machine's camera when joining a meeting. New SNORT(R) rules fire when they detect a file containing Zoom client information trying to disclose sensitive information.
Snort SIDs: 50724 - 50729
Title: Anubis malware returns to haunt Android users
Description: Researchers at Trend Micro recently discovered more than 17,400 new samples of the Android malware. Anubis has targeted several different banking apps on Android stores, installing malicious espionage and banking trojan capabilities onto users' mobile devices. The actor behind Anubis has been active for at least 12 years, constantly making updates and adding new features. All four of these rules fire when Anubis attempts to make an outbound connection to a command and control (C2) server.
Snort SIDs: 50734 - 50737
