That's the news!

That's the news. Stay safe out there.

FireEye has a neat new toolset to crowdshare malware patterns. I haven't dug into this yet, but I am fascinated. Malware isn't my thing - I am a web guy - but this is a cool idea.

Microsoft has started killing off TLS 1.0 and 1.1 really for real this time. Really. Interesting take, because in poorer countries who are still using old Android and iOS devices are effectively losing access to the tools. Acceptable losses? Seems so.

That's the news, folks. Hope everyone is well.
Big news this week was the F5 zero day, of course, but on the application side you should review the code for the exploit, which is public. I am not gonna link it here but y'all can google. DO NOT run this on your corporate machines, use your test box and a VM, and just look. Here is a link to the CVE:

We are back on the encryption discussion. Let me make my own, personal, not endorsed by anyone, position very clear. Anyone - ANYONE - can encrypt anything with two coins, a pencil, and a piece of paper. These laws do NOTHING. Nothing at all. Please tell everyone. If you have questions, please ask. If I don't know the answer, I know people who do.
