Hello, welcome to the Friday, March 3, 2017 edition of the Sansanet Storm Center's Stormcast.

0:07.7

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

0:12.8

Robb today has a diary with a sample for a business email compromise, well, at least an attempt of one.

0:20.0

Not a very good one.

0:21.5

The email, in my opinion, is pretty easy to spot as a fake just based on the text of the email.

0:30.8

However, as Raw points out, this email should never have made it into the inbox just because SPF, if properly implemented,

0:41.3

would have dropped this email.

And Palo Alto did a pretty nice job running down the background behind some recent Android Malware.

0:53.3

Now, when I first saw the the headline I didn't really pay much

0:55.8

attention because Android malware after all is somewhat common. Now this particular

1:30.4

been sing-hold for a while now. What Palo Alto actually was able to deduct was that these

1:37.1

seven developers apparently are using a development environment that is it itself infected.

1:44.9

So any application being created with this development environment will include the malware

1:52.2

and as a result will then bundle it up and will be published like this to the Google Play Store.

2:00.1

So very similar to what we have seen with Xcode Ghost a little bit more than a year ago.

2:06.5

In the Xcode Ghost case, it was an OS10 development tool that was infected and then included

2:16.2

itself or included malicious code in compiled binaries.

2:20.3

Something similar may have happened here.
