2017-037 - Asset management techniques, and it's importance, DDE malware

Direct Link: http://traffic.libsyn.com/brakeingsecurity/2017-037-asset_management.mp3

We started off the show talking to Mr. Boettcher about what DDE is and how malware is using this super legacy Windows component (found in Windows 2) to propogate malware in MS Office docs and spreadsheets. We also talk about how to protect your Windows users from this.

We then get into discussing why it's so important to have proper asset management in place. Without knowing what is in your environment, you could suffer gaps in coverage of your anti-virus/EDR software, unable to patch systems properly and even make it easier for lateral movement.

Finally, we discuss our recent "Introduction to Reverse Engineering" course with Tyler Hudak (@secshoggoth), and Ms. Berlin's upcoming trip to New Zealand.

Why asset management?

Know what’s in your environment

CIS Top 20...no wait, it’s the TOP THREE of the 20.

It all builds on this…

Know what’s in your environment

https://metacpan.org/pod/App::Netdisco <- NetDisco (great for network equipment)

 

Where do you store that data? Or is it just enough to know where to get it?

Systems you can pull asset data from:

Patching systems

Chef

WSUS

FIM systems

Tripwire

DLP systems

Vuln Scanners

AV/EDR management

router/switch tables

DNS

Asset management systems are a gold mine for an attacker

Names

IPs

email addresses

 

Coverage gaps in these systems will cause you to lose asset visibility
