Hello, welcome to the Wednesday, June 8, 2016 edition of the Sandcent Storm Center's Stormcast.

My name is Johannes Ulrich, and I'm recording from Baltimore, Maryland.

You may start receiving emails from various larger websites asking you to change your passwords even though those sites

themselves have not been compromised instead what's happening is that several

websites now started looking at some of the password dumps that have been

surfacing from time to time and they're checking if their

own users are using passwords listed in these password files.

The goal here is to eliminate password reuse.

So if you get one of these emails, it's likely that your email and password combination

was found in one of these password lists and you're better off changing your password.

And Checkpoint found an interesting vulnerability in Facebook messaging.

This vulnerability allowed any user to modify messages that another user

had sent after the message was sent. So the recipient of the message would see the message

change in the chat history. Of course, if the user didn't see the message right away, then the

message would appear new and the new content would be displayed. This, of course, could

easily be used to send spam, maverlings or do other mischief. Checkpoint reported vulnerability to Facebook earlier this month,

and Facebook already fixed the issue. And the FAA advised GPS users on the West Coast that

during June on several dates, they may experience extended outages

of GPS due to some testing being performed by the Navy. The testing will apparently be conducted

at the Navy's China Lake facility in the California Mojave Desert.

Now, the further away you get from the test site, the less GPS will be affected close to the

ground and the effect will be limited to higher altitude, which is why the FAA does advise pilots
