@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: Mirai Variant Targets Modems Used By Deutsche Telekom Customers Description: Researchers have been observing what appears to be a Mirai botnet variant targeting Deutsche Telekom customers who use a certain DSL modem. The attacks appear to be exploiting a bug in the implementation of the TR-069 standard resulting in modems "hanging", creating a denial of service for customers who are affected. Deutsche Telekom has developed a patch for the bug that is being exploited and is currently in the process of rolling it out. Reference: https://isc.sans.edu/forums/diary/TR069+NewNTPServer+Exploits+What+we+know+so+far/21763/ Snort SID: 40519-40523,40597-40601,40612
Title: Researcher Identifies Bug in Paypal's OAuth Implementation Description: A researcher has identified a bug in Paypal's OAuth implementation that could have resulted in tokens leaking. The flaw in questions manifests in the token request and acquisition process where the Paypal Authorization Server was also accepting localhost as a redirect_uri. The flaw in question has been fixed by Paypal. Reference: http://blog.intothesymmetry.com/2016/11/all-your-paypal-tokens-belong-to-me.html
