instagram-cyber.github.io is an impersonation phishing page that posed as Instagram to lure the platform's users into handing over account access. It ran as a free GitHub Pages project, with the brand name placed up front in the subdomain to look official at a glance. PhishDestroy first saw it on 2026-09-06. The site went offline on 2026-09-11 and was still dead with an empty root on 2026-10-19.
How the scam works
Pages like this copy Instagram's look and ask visitors to sign in, often under a pretext such as a security check, copyright warning or verification badge offer. Whatever is typed into the form goes to the operator, who can then take over the account, lock out the owner, message their contacts or resell the profile. The page title now reads "Site not found · GitHub Pages" because the project was removed, while our classification reflects the Instagram impersonation detected while it was live.
Evidence
Seventeen of 89 VirusTotal engines flagged the address on 2026-09-16. They include BitDefender, ESET, Fortinet, Emsisoft, G-Data, Forcepoint ThreatSeeker, alphaMountain.ai and the Vietnamese anti-scam group Chong Lua Dao, which makes it a broad cross-vendor consensus rather than a single outlier. Google Safe Browsing lists it under social engineering. urlscan.io returned a malicious verdict and recognized Instagram branding on the page. Phishunt and PhishFeed carry it alongside PhishDestroy.
Infrastructure
The operator registered no domain. The page sat on a github.io subdomain, so GitHub, Inc. is the registrar of record and the content was delivered through Fastly's network in the US, the standard setup for any GitHub Pages site. Free hosting like this costs nothing and can be replaced within minutes, which matches the short lifespan here: about five days between first detection and the page going dark.
What to do
If you entered your Instagram username and password on this page, change the password immediately, plus any other account that reuses it. Turn on two-factor authentication, preferably with an authenticator app, and review the active sessions and login activity in Instagram's security settings to log out unknown devices. Also check that the email address and phone number on the account are still yours, and change the email password too if it matched. Defenders should block the subdomain, watch for new github.io projects that use Instagram's name, and report lookalikes to GitHub so they are removed quickly.

我应该为报告收集哪些信息？
联邦调查局（FBI）指南
Keep original emails, receipts, messages and screenshots in a secure place. A factual timeline helps the receiving authority understand what happened. IC3 evidence guidance ↗
Payment records — if you paid, save the receipt, amount, date, payment provider and recipient details.
Your bank or payment provider — contact its fraud team promptly through official contact details if money or card information was exposed.
当地警方 — 即使无法立即采取行动，也能留下正式记录
A report is not a guarantee of recovery or investigation, but prompt, accurate transaction data can help authorities and service providers trace the incident.
How do phishing scams typically work?
虚假网站 — 与正规网站完全一致的克隆网站，仅域名略有改动
猪的屠宰 — 通过Telegram/WhatsApp/交友软件花数周时间建立信任，随后钱被骗走
退款诈骗 — fraudsters pose as recovery agents and demand upfront fees. Never share a seed phrase or pay before independently verifying the provider
