Hidden Link Analysis Reveals 92% of Suspicious IPs Not Blacklisted

August 11, 2015

Blacklists are a useful and common tool for enterprises actively looking to keep suspicious IP addresses and URLs off their network and away from their infrastructure. Traditional blacklists are populated with information from intelligence feeds, intrusion detection systems, honeypots, and log files. But we at Recorded Future posit that traditional blacklists can be bettered by incorporating threat intelligence from deep and dark Web sources.

By scouring the entire Web for mentions of known malware related to specific domains, we were able to identify nearly 1,400 instances of malware-infested domains that were not recognized on established blacklists. Recorded Future analyzed 890,000 documents that mention malware (including Web pages, tweets, and pastes) from nearly 700,000 Web sources that we track with the Recorded Future Web index. This means that 92% of the suspicious IP addresses identified in our project were not found elsewhere on other blacklists!
