Power of Reverse Whois Lookup

Bedlam wasn’t quite how you intended your day to start. Thankfully, knowing you shouldn’t put it off any longer, you’d reconfigured and baselined your Intrusion Detection System (IDS) earlier that week. And today, before you even had a chance to boil the kettle for your morning brew, your monitoring dashboard lit up like someone had poured fuel on a bonfire and the alarms even woke Chairman Miao, the cat who was nestled cozily under your desk. In fact, as all hell broke loose, bedlam was an understatement.

The coffee could wait…

The culprit was a massive surge in outbound network traffic routed to an unfamiliar server. Your IDS was set to flag any unexpected traffic spikes, and this one has not only triggered the system, but it’d gone ballistic.

Leveraging Reverse Whois Lookup, you explore the suspect server: its origins, who own it, what it’s connected to, etc., and discover a network of domains linked to a threat actor group notorious for sophisticated phishing campaigns.
