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.

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
