Hello, welcome to the Thursday, January 12th, 2017 edition of the Sandsenet Storm Center's Stormcast.

0:07.0

My name is Johannes Orich, and today I'm recording from Jacksonville, Florida.

0:11.8

Pratt today explains what's behind some of the fake parking ticket notifications that you may have seen in your inbox.

0:19.7

Now, most people probably won't click on it,

0:21.9

but then again, hackers use these emails because they know there will be people that click on it.

0:28.6

And, well, what happens if you click on it, a downloader is installed after you enable the macro

0:35.3

checking personal email accounts from work, like webmail accounts. And then of course,

1:39.5

they bypass a lot of the protections that you put into your mail servers with anti-spam and anti-malware.

1:47.0

And when I'm talking about SSL and how to configure it correctly, usually I remind people that

1:52.1

while you should not enable things like SL version 3, probably a much larger risk is certificate

1:59.9

authorities not appropriately checking who is actually

2:04.1

asking for the certificate. And we had yet another case this time it's GoDaddy. GoDaddy had to

2:10.9

revoke over 6,000 certificates, or at least they're saying over 6,100 customers were affected by this because due
