The Most Dangerous Game Hunting Adversaries Across the Internet
Kyle Maxwell Super Special Security Researcher @ iDefense

#YOLOTHREAT
Intelligence Concepts That everyone knows and already agrees on right…?
Data vs Intelligence Intelligence has gone through the intelligence process
Data is a raw piece of information without context
Feedback Analysis Processing Dissemination Collection Requirements Intelligence Cycle
F3EAD While… Find Exploit Finish Disseminate Fix Analyze
The Target
What is Targeting? Making a plan for focusing threat research
& investigation
Targeting Methodologies Actor Centric ~ Target Centric ~ Technology centric
Feeds Needles in Haystacks
“My 5.4 gazillion indicators can beat up your threat indicators.
Garbage in garbage out #ThreatIntel ~ Rick Holland
Honeypots Bringing the Bad Guys to You
Low vs High Interaction High interaction honeypots are a risky
& complicated way to generate high quality intelligence Low interaction honeypots are an easy way to get low value intel on commodity threats
Software Old School: HoneyNet Project New Hotness: Modern Honey Network
by Threat Stream
Vulnerability Information Taking care of your Toys
“Structured vulnerability analysis is not threat intelligence it is requirements
gathering for threat intelligence. ~ @selil
Vendor Information Blogs ~ Reports ~ Services & APIs
Personal Aside to Vendors If you’re going to release a
report, blog post, etc: do not break the Cut and Copy Actions
None
Review Your Own Incidents Mine that fancy Incident Management System…
Review Your Others Incidents By sharing or News mining
The Hunt
What to Analyze Technical Sources
What to Analyze: Hashes Reversing: • C2 info • Developer
artifacts Sources: • VxShare • VirusTotal • malwr.com
What to Analyze: Passive DNS • Single most useful tool
for infrastructure research • What resolved to what, and when? • DNSDB (Farsight), PassiveTotal, VirusTotal
What to Analyze: Whois • Tougher to Acquire • WhoDat
etc for ongoing Tracking
What to Analyze Actors
What to Analyze: Criminal • Primary Weapon: Google • Social
Media (Twitter, Facebook) • Underground forums?
What to Analyze: Espionage • This is hard • Malware
& System artifacts • whois/registrar data • actions over target
How to Keep Tracking
Threat Library • CRITs is popular, MISP also • Lighter
solutions often work • Market hasn't fully addressed this
Web Monitoring Systems • Netflix Scumblr Meta SearcH (Works alongside
Sketchy) • Recorded Future • Lots of custom development
Malware Monitoring • VirusTotal is • Malware feeds with Lots
of custom internal solutions • Maltrieve, Viper, & Cuckoo
Internal Logging • Firewall, IDS, & Proxy • Web, mail,
& DNS • Authentication & Audit
The “Kill”
Incident Response The Entire Goal… Right?
The Imitation Game Don’t let them know that you know
that they know…
Attribution Probably doesn’t matter unless you can do this
Hand Cuffs or Cruise Missiles
KICK ‘EM OUT NOW! Sometimes it’s better to watch for
a while
Intel Driven Responses deny Deceive ⁉️ degrade ⁉️ disrupt ⁉️
Destroy ‼️
Communication Who can make use of this information? ~ Who
might be able to provide additional intel?
The Hunting Stories
Products IOCs & RFIs ~ Short Form Products ~ Long
Form Products
Audience Internal - Team Internal - Organization External - Peers
External - Wide
IOCs - Generalized Stix & OpenIOC
“you pretty much need a PHD in XML to understand
either STIX or TAXII ~ Jeff Bryner
XKCD.com/927
IOCs - Specialized Yara: Malware centric av signature style IOCs,
getting more advanced Snort: Go to for network activity, Comprehensive and well supported
“OH: "Yara is an antivirus that you update using git
pull" ~ @tomchop_
Requests For Intelligence A Q/A requesting very specific Intelligence ~
Shortest form Possible ~ Fastest turn around
Short Form Products Intermediate products to support incident response ~
Focus on actionable Information
Long Form Products Comprehensive “All Source” intelligence products ~ Requires
considerable Time & a well rounded team
The Surprise…
You Can’t Download a Threat Intelligence Until now….
