From the Absolute AppSec Podcast - learned about a really great article on how Account Enumeration is exploited. I get pushback when I put it on reports, but it's a real vulnerability.

America isn't the only country leaving their data exposed.

Exposing secrets in source code is a real thing. I discovered a very cool tool that helps (if you are working in VS Code, which you should be) called Cloak.

Finally, I have mixed feelings about this one. Firefox will stop supporting TLS 1.0 and 1.1 soon and other browsers will surely follow. I get it, there are flaws in those protocols, but they are better than nothing. This feels a lot like gatekeeping to me (older machines run older browsers), and regular readers know that I am not saying that out of political correctness. Lemme know what you think in the comments.

That's the news, folks. Stay safe.
