Hello, welcome to the Friday, January 26, 2018 edition of the Sands and its Storm Centers.

0:07.2

Stormcast, my name is Johannes Ulrich.

0:09.2

I'm recording from Jacksonville, Florida.

Xavier today came across an interesting site that offers ransomware as a service.

0:18.0

All you have to do is provide a Bitcoin address to which the ransom will be paid,

0:22.8

how much ranch them you're asking for, and then it will create the binary for you. Now, the particular

1:33.3

Well, a lip curl apparently had an interesting security flaw ever since it was first released

in 1999.

The problem here is what happens when lip curling counters redirect. What lip curl does if it's
