Introduction
Recently, we are encountering fake websites that imitate brands. These sites gain users' trust by copying original sites exactly and mislead them. When we say copying, it's not just the appearance anymore - workflows, sub-screens, and even user control methods can be copied. Users unknowingly enter their personal information, passwords, or payment details on these sites.
This situation not only causes financial harm to customers but also directly affects brands' credibility and reputation.
Think about it; if such an event happens to your brand... The purpose of this article is partly to highlight the risks and partly to guide proactive measures that can be taken.
Why is the 'clone-site threat' now on our agenda?
Phishing methods are now much more complex: attackers prepare near-identical copies of websites using ads, fake links, or short URL services. These fake sites are so advanced that they can show real content to some visitors while showing different content to others. For example, only users from specific countries or only from mobile devices can be targeted. Even if you log into your own site every day, it's almost impossible to notice this structure.
Also consider your payment system: the user enters a confirmation code or password during payment, but the attacker can use this information for different purposes. Unfortunately, even OTP mechanisms like SMS confirmation are not sufficient at this point.
These are just two small examples. Threats are diversifying every day, and with the development of artificial intelligence, this process is expected to accelerate further. Frankly, we know that preparing fake sites no longer requires days; it has become possible within hours or even minutes.
That's why "fake site detection and rapid response" is no longer an option but a necessity in our brand protection programs.
What is PhaaS?
Have you ever heard of PhaaS? If you don't work at a security software company or in a company's security team, it's probably natural that you haven't heard of it. It's a new concept and a new business line. Its content is also interesting, perhaps the kind that makes you say "no way."
"Phishing as a Service" or PhaaS is a new service model. "Phishing attacks used to be prepared by experienced hackers. In recent years, these attacks have become a service model. Everything attackers need is now ready as a package; they can just buy and use it."
What does this service include?
- Ready-made fake site templates (exact copies of banks, e-commerce sites, social media, etc.)
- Domain registration and hosting (kept confidential on behalf of the attacker, of course)
- Ad/message campaigns (sending fake links to users via SMS, email, even social media ads)
- Management panels (an interface where they can view and organize stolen user information)
- Support & updates (just like a software service, updated templates against new security measures are provided)
People or groups selling this service usually offer it to attackers in exchange for a monthly subscription fee or per-use payment. This way, even people with little technical knowledge can easily conduct phishing attacks. I've heard they even offer credit card installment options. Think of it like a "Netflix subscription"; only here the content offered is fake sites and phishing tools.
Clone Site Attack Methods
The purposes in these attacks are also different now. Attack types can be designed for different purposes. Let's list methods according to some purpose types:
Traffic Acquisition
The attacker directs the traffic they want to the region they want using Google Ads, social media ads, SMS, or short-link services. In other words, your traffic is being stolen. Traffic means content views, sales, advertising, customer potential, or the customer directly, so it's very important.
Redirect Chain
The attack redirects to the cloned site through short links or names very close to the main site name (you wouldn't believe it, not just one but several redirects). This chain is used because it hides the actual site information.
Exact Cloning (Clone Copy)
The target site is copied to almost exactly resemble the original site with its logo, text, footer, form flow, and payment screens. Unfortunately, including workflows, payment structures, and security measures.
Cloaking / Conditional Display
The attacker uses cloaking techniques to show the content they want only from specific IPs (e.g., target country, region, mobile/fixed traffic) or in specific referrer/user-agent combinations. In other accesses, empty, broken, or different content can be served.
Checkout-exploit / Verification Abuse
At the payment stage, fake "verification" windows (e.g., "Verified by ...") request OTP or password from the user. The user enters the code thinking it's a real purchase transaction, and the attacker uses it to add a card to a digital wallet or take over an account.
How Can We Take Precautions?
Up to this point, I've tried to explain those who are preparing for attacks with a very professional approach. I can say that those of us who want to respond must be just as professional.
Moreover, this is unfortunately not a job where you can say "I did it once, I'm ready." Technology is developing rapidly, but at the same speed, new methods that make attackers' jobs easier are also emerging.
Checkpoints
- URL similarities: very small changes (additional word, character change, punycode, etc.) may give a chance to catch if followed
- Newly registered domains: hidden/anonymous WHOIS information might give clues
- Redirect chains: many headers and intermediate domain connections may contain hidden clues
- Conditional display: content visible from target country IPs being different from content visible in other regions
- TLS certificates: short-lived or later-added certificates, issuer inconsistencies
- Checkout flow: unexpected third-party requests or "Verified" type popups
- Device fingerprint: device profile differences at auth and transaction moments
- ASN/host analysis: multiple pages with different brand names on the same host
Evidence Package Preparation
I know this is every technical team's dream, imagine there's a risk, you've worked on it, you're at a certain level of knowledge, and you catch a high-risk point. There are certain points you need to do at the moment you catch it, it's important to complete them without skipping. You need to collect evidence like a detective.
How Do We Prove It?
- Full access URL and timestamp
- High-resolution screenshots (with URL visible)
- HAR / network logs (especially important in the redirect chain)
- Video screen recording (comparative if there's different behavior)
- WHOIS data instant capture
- IP address, ASN, reverse DNS hosting provider information
- Comparison report (main differences with the original site)
- Ad/Ads data (if available, Ads ID, ad URL, click referer)
Operational Flow — 0–72 Hours
0–6 hours (Verification & Evidence)
If you've caught it but don't have customer loss yet, you're lucky, the time starts from zero. Simultaneous access tests with target country IP and other geographic IPs can be done. Continuous similar domain checking can be done. You should immediately take HAR + video + screenshots.
6–24 hours (First Notifications)
It's time to start taking countermeasures. It's time to apply to the attacker's hosting provider you caught. Sending an evidence package when applying is critically important.
24–72 hours (Monitoring & Escalation)
You may not get a response from hosting/registrar companies, what to do is apply to an upper level, namely the upstream operator, national CERT, and regulators. It's beneficial to consult with your legal team.
Conclusion
Clone sites are not just a technical problem; they are a serious threat that targets brands' credibility, customers' trust, and direct revenues. Moreover, with methods like redirect chains and cloaking, detecting these attacks is becoming increasingly difficult.
The main issue is this: Once a brand loses its credibility in the customer's eyes, regaining it requires both time and significant cost. Therefore, what needs to be done is not to react after experiencing an attack; but to always be ready with continuous monitoring, rapid evidence collection, and a clear intervention plan.
The small steps you take today — automated checks, evidence pipelines, ready escalation processes — may be your strongest investment to prevent the major reputation loss that could occur tomorrow.
Author's Note: The clone site threat is not just the job of technical teams; it requires coordinated work of marketing, customer service, legal, and communication teams. This article aims to help organizations establish rapid, evidence-based, and effective intervention processes by concretizing risks and operational steps.
