Cybersecurity: How I Stopped an Instagram Exploit Making OG Usernames Duplicable

A few nights ago, a brand new Instagram profile loaded on my phone with a handle that serious collectors would call impossible. No auctions. No internal favors. No transfer history. Fresh account. High value name. Live.

My team protects founders, creators, and public figures from doxxing, impersonation, and cyber reputation attacks. We spend our nights at the edge where platform policy meets attacker creativity. That night we recorded something we were not supposed to see: previously blocked or legacy usernames appearing on new accounts in real time, including one character and historically restricted words that had been locked for years.

We did not brute force anything. We did not touch production data. We stayed within routine, publicly documented account creation flows using test devices and test identities. What we observed looked like a validation failure between the display name and username layers. The result was simple to describe and serious in practice. Duplicate or historically blocked handles could attach to new profiles long enough to go live.

I am used to cleaning up after chaos. That night the job was to raise the alarm before chaos scaled.

A founder’s log at 2 a.m.
I run Leyes Media and LeyesX, two companies that operate the back office of modern influence. We automate brand presence, reputation security, and media orchestration for people whose names are currency. We see phishing waves before they trend. We watch botnets warming up. We spot the first ripples of a new exploit in the chatter of people who try to monetize it.

Around 10 p.m. we saw screenshots of unusually clean handles on zero follower accounts. Some looked like revives of previously banned names. Others mirrored protected namespaces that normally return errors. We spun up test devices, screen capture, and a clean browser environment. By 1 a.m. we had multiple confirmations on iOS and mobile web along with timestamps, device IDs, and build versions.

I am careful here. I will not publish a tutorial. I will not help an attacker. At a high level, the issue appeared to sit in the account creation flow and client side handling of username input. By confusing state between display name and username, and by introducing a non visible character at the right moment, routine checks could be bypassed long enough for the claim to complete. Re entering the flow a few times seemed to refresh tokens in a way that allowed restricted handles to appear on fresh accounts. We reproduced on iOS and mobile web. It did not look region-locked, but some bad actors reported the use of French VPNs. That is where I stop. The rest is for the platform’s security team.

Coordinated disclosure, not spectacle
We operate with a simple rule. If we can verify an issue that creates real impersonation risk, we document it like forensic accountants and report directly to the platform under coordinated disclosure.

Timeline and initial platform response
• Night of August 18 (ET): first confirmations of revived and duplicate style handles on new profiles. Telegram and Discord communities focused on social media gray markets began attempting replication within hours.
• August 19 (ET): we submitted a responsible disclosure to Meta with an evidence bundle. Meta acknowledged receipt the same day with, “A member of Meta’s security team has seen your report and performed an initial evaluation,” and continued work toward remediation.

Before sunrise on the 19th we prepared an evidence bundle that included:
• Screen recordings from clean devices showing end to end behavior.
• Device, OS, and app build versions.
• Exact timestamps and a short list of test accounts.
• Before and after captures of OG style handles going live on new profiles.
• Notes from takedown attempts through official channels.

We notified Meta through responsible channels and offered a private brief. We also alerted two reporters who cover platform integrity and AI safety under embargo. Sunlight can inform or it can inflame. If you shout while the door is still open, you multiply harm. If you stay silent too long, a market industrializes the loophole.

Residual exposure after the initial fix
Meta moved quickly, and we appreciate the effort. Our continued tests, however, showed a residual path after the first mitigation. On desktop, when simulating a mobile session and using a client side script for input handling, the behavior could still be reproduced under limited conditions. We will not publish technical steps. The point is simple. Edge paths can survive an initial patch, so sustained testing matters.

Reporters from The New York Times, The Washington Post, The Wall Street Journal, WIRED, and Forbes requested comments and context on the impersonation risk and the disclosure timeline.

What we saw in the wild
Once word spread inside niche communities, abuse patterns followed a familiar script:

• Impersonation bait. Duplicated handles attached to new accounts, then used to DM followers of the original profile with crypto pitches or malware.
• Policy regression. Banned or policy violating names reappearing quietly on fresh profiles.
• Marketplace pressure. Brokers promising “revives” for four and five figures. This often ends in extortion or recovery traps.
• Psychological harassment. New follows and mentions from handles that look authoritative at a glance. We logged threatening bios and follow notifications designed to trigger fear.

Why this matters now
Colliding identities break the platform trust model and supercharge impersonation, phishing, and brand hijack scams. Blue check confusion makes it worse. In at least one case we observed a verified profile’s handle cloned to a second live account and used for outreach. Black market acceleration followed. Brokers began offering and delivering duplicate usernames and “resurrected” banned handles with timed delivery windows and escrow chats. We verified multiple instances where two live profiles displayed the same handle in parallel, and cases where previously banned OG handles were reassigned and put up for sale for thousands of dollars.

Safe examples we can share
We will not publish weaponizable steps. We can share a concise, high level technical timeline, public URLs for affected pages, and broker marketing artifacts. Examples of look alike or revived handles include: @instagram (yes, a duplicated handle of the actual social media platform with 694M followers), @kill, @cb (duplicated, impersonating another person), @stuck, @pmc, @crypto, @fraud, @brad, @ye (impersonating Kanye West), and even 1 character handles like @m or @1. Imagine someone doing this “hack” for a government official or a celebrity, impersonating them to scam people, but we prevented that.

On the record, from the reputation defense side
For creators and enterprises, the funnel is simple and dangerous. A credible looking handle sends outreach, a small group engages, then payment links and recovery traps follow. Short term mitigations include strict two factor and recovery hygiene, out of band verification for any transaction initiated by DM, and a named owner for impersonation watch during high activity windows.

The deeper problem is not code
It is the intersection of identity, incentives, and automation. AI agents now drive target selection, write credible DMs, and scale rapport in minutes. Gray markets reward the first mover. Policy gaps become businesses. Every platform should assume adversaries run agents too.

Why this mattered for public safety
Left unchecked, this exploit enabled duplication or revival style handles on fresh accounts. In test scenarios we also observed pathways that could pair such handles with Meta Verified on business accounts without a government ID, since business verification can be tied to a business name. In some cases, previously verified personal accounts appeared able to re verify without a new ID check after canceling and re enrolling. Combined with the handle issue, this created a credible risk of verified impostor accounts for high profile figures and institutions, including major companies and public officials. The public interest is clear. Preventing verified impersonation protects consumers, markets, and election season integrity.

The fix is not only a patch. It is measurement, red team pressure, and a public escalation path that creators and small businesses can actually use. When a crash happens on the highway, traffic slows. When an exploit like this opens, platforms need rate limits, alarms, and a human review wedge until the patch holds.

What readers can do now
• Treat any message from a familiar looking handle as unverified. Tap through to the profile and check the URL.
• Look for subtle glyph differences.
• Lock down two factor and recovery flows on the accounts that matter.
• If you run a brand or creator account, assign someone to impersonation watch for the next few days.
• Do not transact based on a DM. Move the conversation to a known, out of band channel.

Why this work belongs in the public interest
I build systems that automate attention. I also build systems that protect people from the worst versions of the internet. Responsible disclosure exists because both things are true at once. AI helps me monitor more safely and sleep more like a human. It also raises the stakes for identity security at platform scale. The public interest is served when independent researchers can report quickly, platforms can respond quickly, and creators can recover quickly.

I did not publish a tutorial. I published a warning. The door was real, the risk was immediate, and it is now closing because we reported with evidence. Identity is infrastructure now. Treat it with the same rigor as payments and privacy, or the next wave of impostors will not ask for permission.
