Parked Domains Emerge as a Primary Channel for Malware and Phishing

The landscape of domain parking has transformed dramatically over the past decade, shifting from a relatively benign monetization strategy to a sophisticated vector for cybercrime.

New research into the modern parking ecosystem reveals a startling reality: over 90% of visitors to parked domains encounter malicious content, scams, or phishing attacks a stark reversal from conditions found just eleven years ago, when fewer than 5% of parked domains delivered harmful content.

Parked domains, once dismissed as bland advertising repositories, have become a primary hunting ground for threat actors exploiting a complex ecosystem of domain owners, traffic distribution systems, and advertising networks.

The transformation reflects both deliberate abuse by cybercriminals and unintended vulnerabilities created by legitimate business practices in the parking industry.

The threat from parked domains begins with lookalike domains and common typos. During research into domain parking practices, investigators accidentally visited ic3.org instead of ic3.gov the FBI’s Internet Crime Complaint Center and were immediately redirected to a fraudulent “Drive Subscription Expired” scam page.

Under different circumstances, that same domain could have delivered information-stealing malware or a trojan instead.

What makes this particularly dangerous is the dual nature of parked domains: when scanned by security tools or accessed through VPN services, they display harmless parking pages, creating a false sense of security.

Real users accessing from residential IP addresses, however, experience an entirely different outcome they are funneled through traffic distribution systems controlled by threat actors and eventually directed to malicious content.

The Role of “Direct Search” Parking

At the heart of this threat ecosystem lies a monetization model called “direct search” or “zero-click parking.” Domain owners opt into systems where traffic is sold to advertisers through real-time bidding, similar to legitimate advertising exchanges.

Users typing a domain name are redirected through multiple intermediaries each performing device fingerprinting and profiling before finally reaching a landing page.

In practice, this system creates a profitable supply chain for malicious actors. A single domain may pass through multiple advertising networks before reaching a final advertiser, each layer adding another hop in the redirection chain and obscuring accountability.

The disconnect between domain owners, parking platforms, and final advertisers creates precisely the kind of opacity that enables crime to flourish with minimal consequences.

Research identified three previously unreported actors operating large-scale, professionally managed domain portfolios targeting different demographics with thousands of lookalike domains.

The first actor operates nearly three thousand lookalike domains through custom name servers, including common typos like gmai.com.

The chatterjamtagbirdfile[.]monster site said, “Your archive is ready” and gave us instructions to download the file and provided a password for the archive.

Beyond malvertising, the actor actively collects personal information through email misdirection and operates business email compromise campaigns distributing trojan malware.

A second actor employs sophisticated “double fast flux” techniques rapidly rotating both authoritative name servers and IP addresses to evade detection.

This rare evasion method, combined with a portfolio of approximately 80,000 domains, demonstrates professional-grade operations targeting adult content, gaming platforms, and illegal services.

The third actor operates domaincntrol.com, a domain differing by a single character from GoDaddy’s legitimate name servers.

By exploiting innocent typos in DNS configurations and leveraging expired domains containing outdated links, this actor routes traffic through malicious infrastructure.

Recently, this actor added targeted capability against Cloudflare Secure DNS users, demonstrating evolving sophistication and the ability to target specific user populations selectively.

Inadvertently Fuel the Problem

Contributing to the escalating threat, Google’s recent policy changes requiring advertisers to opt-in to parking traffic inadvertently pushed domain investors toward direct search parking models.

The most popular targets were Netflix, Youtube, Google, Pornhub, and Newtoki, which is a platform for unauthorized distribution of manga and comics.

As traditional advertising revenue declined, parking platforms actively recommended direct search as an alternative revenue source, creating conditions that may increase user exposure to malicious content.

While unscrupulous advertisers deliver the malicious content, domain portfolio owners actively participate in user profiling and selective traffic routing, playing an underreported role in the threat landscape.

As direct search parking adoption accelerates, the risk to internet users continues to escalate, making even the simplest typo potentially catastrophic.

Addressing this threat requires greater transparency throughout the parking ecosystem and coordinated action from platform operators, domain registrars, and security researchers.
