Regular Expressions Search
CapLoader’s “Find Keyword” window has been extended with an option to
search flows using regular expressions (regex) as an alternative to searching for strings or byte sequences.
With help of the powerful regex syntax built into .NET
this new search option enables very flexible searching.

You can learn more about regex searching with CapLoader in our short video called
“Detecting the Pony Trojan with RegEx using CapLoader“.
OSINT Lookups of IP Addresses and Domains
We added support for querying online services for IPs and domain names to the
latest release of NetworkMiner,
now it’s time to add this very handy feature to CapLoader as well.
Right-clicking a Flow, Service or Host in CapLoader brings up a context menu with links to
various online resources that might have more details regarding the clicked IP address or
The services available for IP address OSINT lookup include:
APNIC Whois, Censys, Cymon, ExoneraTor, Google Public DNS, GreenSnow.co, Hurricane Electric, IBM X-Force, Internet Storm Center, mnemonic Passive DNS, PacketTotal, SecurityTrails, Shodan, ThreatCrowd, ThreatMiner, UrlQuery and VirusTotal.
The domain name lookup menu contains a similar set of providers:
Cymon, Google Public DNS, Google Safe Browsing, Hybrid Analysis, IBM X-Force Exchange, mnemonic Passive DNS, MXToolBox, MyWOT, Norton Safe Web, PacketTotal, SecurityTrails, ThreatCrowd, ThreatMiner, URL Void, UrlQuery, VirusTotal, Website Informer, Webutation and Whoisology.
The dynamic protocol detection (or Port Independent Protocol Detection, aka “PIPI”)
in CapLoader has been improved to support even more protocols than before.
We have also fine-tuned the protocol identification algorithm to be both faster and more accurate.
