@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: Two serious bugs in WordPress affect popular plugins
Description: WordPress patched two vulnerabilities in two of the most popular plugins available on the content management system. They both could allow an attacker to run extensions on top of affected websites. While WordPress has patched these bugs, the two plugins still appear to be downloaded often.
Snort SIDs: 49541 - 49543
Title: Trickbot dropping IcedID banking trojan
Description: Security researchers recently discovered that the IcedID banking trojan and the Trickbot dropper may be more closely related than once thought. Ties between the two malware families may even date back to six years ago, although they were discovered about a year apart. Researchers with IBM's X-Force say there's been a recent uptick in threat actors working together to deliver different kinds of banking trojans.

ID: CVE-2019-9970
Title: Signal Homograph Domain Spoofing Vulnerability
Vendor: Signal
Description: Signal is exposed to a domain-spoofing vulnerability because it fails to adequately handle homographs in international domain name domains.
