2017-018-SANS_course-EternalBlue_and_Samba_vulnerabilities-DerbyCon contest details

We discuss SANS courses, including the one I just took (SEC504). How did I do in class? You can listen to the show and find out.

Since it's been a few weeks, we also discuss all the interesting WannaCry reports, the ease at which this vulnerability was exploited, and why would a company allow access to SMB (tcp port 445) from the Internet?

We discuss some upcoming training that we are holding starting 14 June. Ms. Sunny Wear will be doing 3 sessions discussing the use of Burp, and showing how to exploit various web application vulnerabilities. Details are in the show notes and in our Slack Channel.

Ms. Sunny Wear is doing a web app security class

Starts June 14th at 1900 Eastern (1600 Pacific, 2300 UTC)

Sign up for the class at the $20 dollar Patreon level (if you plan on attending)

Sign up for immediate video access at the $10 Patreon level (cannot attend class, but want to follow along)

Everyone will have access to the Slack Channel to follow along with the class, ask questions, etc (join our #slack channel for more information)

SHOW NOTES:

SANS experience

Pity Quincenera - I (bryan) sucked

Need more experience

Speed kills (I (bryan) got flustered and I shutdown) you took speed?

No Kali - was surprised, until I thought of why :D

Was not helpful to my team (jacek, ryan, Michael C., David)

John Strand was phenomenal

Frank Kim was great

The audio was not, unfortunately :(

Samba/SMB (port 445) vulns

Use case for having it exposed?

**** OPEN TO SUGGESTIONS *****

What does that say about the company?

No security team, or the security team is ineffectual about telling people about the risks?

What

MS17-010 is the new MS08-067

Over 400,000 open to the web

2017-017-Zero_Trust_Networking_With_Doug_Barth,_and_Evan_Gilman

Zero trust networking may be a foreign concept to you, but Google and others have been utilizing this method of infrastructure and networking for quite a while now. It stands more traditional networking on it's head by not having a boundry in the traditional sense. There's no VPN, no ACLs to audit, no firewall to maintain... Sounds crazy right?

Well, it's all about trust, or the lack of it. No one trusts anyone without a proper chain of permission. Utilizing 2FA, concepts of port knocking, and CA certificates are used to properly vet both the host and the server and are used to keep the whole system safe and as secure as possible.

Sounds great right? Well, and you can imagine, with our interview this week, we find out that it's not prefect, people have to implement their own Zero Trust Networking solution, and unless you are a mature organization, with things like complete asset management, data flow, and configuration management, you aren't ready to implement it.

Join us as we discuss Zero Trust Networking with Doug Barth (@dougbarth), and Evan Gilman (@evan2645)

All good points, except no one wants to do the needful bits (ID’ing information, data flow, proper network design)

Where is this Google article???

Who benefits from this? Network engineers, apparently… :)

Devs?

IT?

Sounds like a security nightmare… who would get the blame for it failing

How do we keep users from screwing up the security model? Putting certs on their personal boxes?

Runs counter, right? We are used to not trusting the client…

A Mature company can only implement

Device inventory

Config management

Data flow

Asset management

Micro-services?

Brownfield networks

Sidecar model -

Certain OSes not possible

2017-016-Fileless_Malware, and reclassifying malware to suit your needs

Malware is big business, both from the people using it, to the people who sell companies blinky boxes to companies saying that they scare off bad guys.

The latest marketdroid speak appears to be the term 'fileless malware', which by definition...

FTA: “Malware from a "fileless" attack is so-called because it resides solely in memory, with commands delivered directly from the internet. The approach means that there's no executable on disk and no artefacts ("files") for conventional computer forensic analysis to pick up, rendering the attacks stealthy, if not invisible. Malware infections will still generate potential suspicious network traffic.”

https://www.theregister.co.uk/2017/04/28/fileless_malware_menace/ -- by definition, not ‘fileless’

But many of the 'fileless' attacks require a 'file' to be opened to enable the initial infection.

This week, Michael Gough (@hackerhurricane) comes on to discuss his latest blog post (http://hackerhurricane.blogspot.com/2017/05/fileless-malware-not-so-fast-lets.html) and we discuss the fact that a lot of malware classification and categorization and how it fails to actually convey to leaders what it affects
