Here’s the uncomfortable truth about crypto security:
while you’re reading this sentence, at least three new phishing sites targeting crypto users just went live.
Before you finish this article, there will be dozens more.
They’re clones of major exchanges. Fake wallet sites. Counterfeit DeFi platforms. Perfect replicas of legitimate projects, right down to the SSL certificates and user interface. The only difference? They’re designed to drain every satoshi from anyone unfortunate enough to land on them.
And here’s the part that should keep you up at night: most of these sites will operate for hours, sometimes days, before anyone even knows they exist.
The Problem With Playing Defense
Traditional security approaches treat domain threats like a game of whack-a-mole. A phishing site gets reported. Security teams investigate. Evidence gets gathered. The site finally gets taken down. Meanwhile, the damage is done, and the attackers have already spun up five more domains.
This reactive model worked fine when websites were static and attacks were unsophisticated. But crypto changes everything. When users connect their wallets to a malicious site, funds disappear in seconds. There’s no “undo” button. No fraud department to call. No chargeback mechanism.
By the time you’ve confirmed a domain is hostile, documented the evidence, and initiated takedown procedures, the scammers have already moved on.
The mathematics are brutal: threat actors can register and deploy new attack infrastructure faster than any manual process can identify and respond to it. They’re industrialized and adapting quickly to AI while you companies still using reactive methods.
Why Generic Blocklists Miss the Mark
Standard DNS blocklists and threat feeds weren’t built for the crypto world. They catch obvious malware distribution sites and known phishing infrastructure, but they’re blind to the specific techniques attackers use against blockchain platforms:
- Homoglyph attacks using Cyrillic characters
- Brand-new domains registered minutes ago
- Sophisticated clones hosted on legitimate cloud infrastructure
- Subdomain attacks that slip past domain-level filters
These threats are invisible to traditional security tools.
Even when generic feeds do catch crypto-related threats, they’re usually days behind. The feed updates once every 24 hours. The phishing site was live for 18 hours before detection. Your users had nearly a full day of exposure.
That’s not protection. That’s documenting the evidence.
Intelligence That Moves at Attacker Speed
What changes the equation is intelligence that operates in the same timeframe as the threats themselves.
When we protect our client portfolios at Domainsure, we’re constantly scanning for hostile domains targeting their brands, their users, and their ecosystems. We find phishing sites as they spin up. We catch clones as they deploy. We identify malware distribution infrastructure before it goes active.
This is not the same as occasional scanning or periodic checks. It is continuous monitoring across every angle attackers use:
- new domain registrations
- DNS changes
- SSL certificate issuance
- hosting patterns
- and content analysis.
The intelligence we gather doesn’t just protect our clients—it reveals patterns across the entire crypto threat landscape. When we spot a new phishing campaign targeting one exchange, we’re often seeing the early stages of attacks that will hit dozens of platforms.
That information has value beyond our client base. Which is why we’re making it available.
The Crypto Defender RBL: Real-Time Threat Intelligence
The Domainsure Crypto Defender RBL is a real-time feed of hostile domains we’ve identified targeting crypto platforms.
The feed includes:
- Live phishing sites
- Active clones
- Malware distribution points
- Threats targeting Bitcoin exchanges, wallets, DeFi platforms, token projects, DAOs, and blockchain infrastructure
The feed updates constantly as new threats emerge. When we identify a hostile domain, it’s added to the RBL within minutes. Security vendors, DNS resolvers, and service providers can query the list and get immediate answers about whether a domain is flagged.
What it does:
- Provides intelligence about threats as we discover them
- Updates constantly as new threats emerge
- Flags domains within minutes of identification
What it doesn’t do:
- Make blocking decisions for you
- Automatically implement policies
- Control how you use the intelligence
You query the RBL. You get back data about flagged domains. What you do with that information is entirely your decision. Block at the DNS level. Flag for review. Add to your own threat feeds. Trigger alerts. Feed into your security stack however makes sense for your architecture.
We handle the detection. You handle the response.
Technical Implementation
The RBL uses standard DNS-based queries, which means integration is straightforward for anyone already working with threat intelligence feeds.
Query format: {domain}.crypto.rbl.domainsure.zone
If the domain is flagged in our system, you’ll get a response. If it’s clean or unknown, you won’t. Simple, fast, and designed to integrate with existing security infrastructure.
For organizations that need deeper integration, we also offer access to our Response Policy Zone (RPZ), which allows DNS servers to automatically implement policies based on our threat intelligence.
Why This Matters
The crypto space has enough problems without every project having to build its own threat intelligence operation from scratch. Attackers share infrastructure and techniques. Defenders should share intelligence.
We’re releasing this feed because the threats we identify protecting our clients are the same threats hitting the broader community. When we catch a new phishing campaign, there’s no competitive advantage in keeping that information private. The faster that intelligence circulates, the harder it becomes for attackers to operate.
This is intelligence that exists anyway. We’re just making it accessible.
If you’re running security for a crypto platform, operating DNS infrastructure, or building security tools for the Web3 space, you can start using the Crypto Defender RBL today.
Query the feed. Test the integration. See if the intelligence we’re providing fills gaps in your current security posture.
