@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: Indian human rights advocates targeted by NetWire malware
Description: Attackers targeted several human rights activists in India between January and October of 2019 with the NetWire malware, attempting to intercept their communications. Researchers say the victims opened spear-phishing emails, which eventually led to the infection. NetWire can steal users' audio recordings, steal credentials and log keystrokes. All the targets are advocating for the release of protestors who were jailed after demonstrations in 2018.

Snort SIDs: 54284, 54285
Title: Remote code execution vulnerability in Firefox's SharedWorkerService function
Description: The Mozilla Firefox web browser contains a vulnerability in its SharedWorkerService function that could allow an attacker to gain the ability to remotely execute code on a target's machine. This vulnerability can be triggered if the user visits a malicious web page. The attacker can design this page in a way that it would cause a race condition, eventually leading to a use-after-free vulnerability and remote code execution.
