Over the past few weeks, a wave of fake emails impersonating OpenAI has exploded: warnings about "a problem with your ChatGPT Plus payment," bogus invoices, cloned apps and pages using the real logo. It is not an isolated case. In the second quarter of 2026, ChatGPT entered the ranking of the 10 most impersonated brands in phishing attacks for the first time, according to Check Point's Brand Phishing Report.

The short answer for a business owner: this is not just an OpenAI problem, nor only an IT issue. It is a pattern. When a brand goes mainstream, criminals clone it. And your best defense —beyond common sense and security tools— is the authority of your own brand: being the official source that is easy to verify, both for people and for the AI that now answers the question "is this real?".

What is happening (and why it matters even if you are not OpenAI)

Brand phishing works because it uses names people recognize and use every day. According to Check Point, Microsoft remains the most impersonated brand (23% of attempts in the quarter), and the top five account for more than half of all cases. Technology is the most imitated sector, followed by social networks and banking. The underlying read: as a platform moves from novelty to daily habit, it becomes as attractive to fraud as any bank.

OpenAI itself describes the mechanism of these scams as "ping, zing, sting": cold outreach, generating enthusiasm or panic, and then extracting money or data. In its October 2025 report, it explains how it disrupted scam networks operating from several countries. One figure worth keeping in mind so you do not panic: OpenAI estimates that ChatGPT is used up to 3 times more often to detect scams than to commit them.

Why your brand could be the next bait

You do not need to be a tech giant. Being recognizable in your niche is enough. The scheme is simple: a scammer sends an email "from your company" to your customers, builds a cloned page of your store, or poses as your support team. You pay the cost: even if the deception never touches your systems, the scammed customer associates the bad experience with your brand. The damage is reputational and silent.

The defense is not only IT: it is brand authority

This is where SEO and AI search optimization stop being "marketing" and become defense. When someone doubts whether a message is real, they do two things: search for the brand on Google or ask an AI. If your brand is the clear, consistent official source —a solid owned site, verifiable official channels, coherent information across the web— two good things happen: people quickly confirm what is really yours, and AI assistants (ChatGPT, Google's AI Overviews) cite you as the reference instead of a copy.

Our view at Seotronix is blunt: the same signal that makes AI recommend you is the one that makes impersonation harder. A brand with a weak or inconsistent presence is easy to imitate, because no one —neither a person nor a model— has a clear reference for what "the real thing" looks like. Building that reference is reputation and authority work, and today it is also brand-security work.

Checklist: how to tell if a communication is real

Save this and share it with your team. It works for OpenAI and for any brand:

How we shield a brand through SEO

When we build a brand's authority, what makes it more visible is also what makes it harder to fake. In practice: consolidate and declare official channels; keep brand consistency (name, contact details, identity) across the whole ecosystem; use Organization and sameAs markup so search engines and AI know which profiles are really yours; earn presence in the sources AI cites; and monitor mentions and domains that imitate your brand. It is not a traditional security checklist: it is building a digital identity so clear that the copy stands out.

Frequently asked questions

Does OpenAI send emails asking for your password or payment details?

No. No legitimate company asks for passwords or card details by email. If an email claims to be from OpenAI and asks for that, it is phishing.

How do I check whether a ChatGPT or OpenAI email is real?

Do not use the links in the email. Check the sender domain and, if in doubt, go straight to openai.com or the app, log in, and review billing there. OpenAI has an official form to report fraudulent activity.

Can a small business be impersonated too?

Yes. You do not need to be a tech giant: any brand recognizable in its niche works as bait to deceive its customers or suppliers. The main damage is reputational.

What does SEO have to do with brand impersonation?

When someone doubts whether a message is real, they search for the brand on Google or ask an AI. If your brand is the clear, consistent official source, people quickly confirm what is yours and AI assistants cite you instead of a copy.

Brand impersonation is no longer a problem exclusive to big tech. The good news is that what protects you is the same thing that helps you grow in search and in AI. If you want to understand how AI decides who to name, see who ChatGPT cites and how to get your website into ChatGPT. Building brand authority is not just marketing: today it is also security.
