Hello, welcome to the Monday, December 21st, 2020 edition of the Sandcent Storm Center's Stormcast.

0:08.1

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

0:13.7

This week and next week, of course, I hope many of you do get to take a couple days off and we'll have only three podcasts this week as well

0:25.4

as next week. So no podcast on Christmas Eve and Christmas Day as well as on New Year's Eve and

0:34.4

New Year's Day. Unless of course we have something interesting and new happening.

0:40.2

And with that, we're sort of playing a little bit on a summary about the Solar Winds event,

0:45.9

a little bit an update. If you have any specific questions about this event or anything that

0:52.0

you would like to have covered in more detail, please let us know,

0:56.8

and I expect we'll probably do something next week.

1:01.6

But well, just about a year ago, we did have the Citrix vulnerability keeping us busy over

1:08.8

New Year's, and Jan took a closer look at how organizations are

1:14.6

doing patching this vulnerability. Looks like we only got actually a couple hundred systems left

1:21.9

according to Shodan that are still vulnerable and who knows how many of them are actually honeypots.

1:28.6

So only 4.5% of the originally infected systems are still exposed, which actually is pretty good.

1:38.5

Of course, this vulnerability was pretty much exploited instantly, which made it a high priority item for people to fix. And in

1:47.5

some cases, at hackers who took over systems may have either patched a vulnerability or

1:54.4

turned the systems unreachable. And one neat feature of process explorer, which comes as part of CIS Internals, is the ability to have a binary that you find running, that you may consider suspicious, check with virus total.

2:13.2

So in this case, CIS internals does calculate a hash of the particular binary and then sends it off to Virus Total.

2:21.6

Sadly, it looks like the last couple days that this functionality is not working.

2:28.0

Maybe an issue here with Virus Total, maybe sort of a change in the API or such, but this appears to be more problem

2:35.4

with Virus Total than with Process Explorer at this point.

2:41.1

And often on, there is a lot of talk about the need of governments to intercept encrypted
