MALWARE OF THE MONTH:New Dridex version
Delivered via Office document or Email with URL
wscript/csript downloads bad binary named Chrome.exe
Calls Scheduled task for persistence
Chrome calls msra.exe for comms
C:\Windows\syswow64\Msra.exe chrome.exe
So another LOLBin ? This is what prompted this podcast
TOPIC OF THE DAY:Laughing at Binaries - LOLBin/LOLBasWhat is a LOLBin and LOLBas?
It stands for Living off the Land Binary and Scripts
Libraries too, Dlls
What started all this?
@SubTee Casey Smith efforts on Application Whitelisting bypasses from 2015 ish where he found ways to use existing binaries on the system to do bad things like RegSvr32, RegAsm, RunDll32, and several others
Why are these an issue for us Defenders?
Well Pentesters and Red Teams use them to get around security solutions like AV, EDR and App Whitelisting
Do these normally execute? If so how noisy are they?
Some are noisy
What do we need to watch out for?
Command line parameters are key
What is are the parameters they are executing with these utilities
Are there any lists people can use?
Malware Archaeology Logging page has a list and link to Oddvar’s page
What about security solutions, do we need to be concerned with these?
Yes, many AV and EDRs will not have alerts for these items
You will need to build some alerts and filter out the good/noise
What about logging theme?
Use the list(s) and build a lookup list that you can add to 4688 events or Sysmon 1 and 7 events and monitor them
What about MITRE ATT&CK, do they reference these?
Yes, there are several of these mentioned in MITRE ATT&CK, so map your tools to ATT&CK Techniques
Are there ways to test for these LOLs
What else do people need to watch out for?
