PhishDestroy threat report

Overview

baseswap-app.github.io is an impersonation phishing page built to pass as BaseSwap, a decentralized exchange on the Base network, and it targets traders who search for the swap app and land on a lookalike. PhishDestroy first saw it on 2026-09-14. The site has been offline since 2026-09-21, and it was still dead when last checked on 2026-10-19.

How the scam works

Fake DEX front-ends copy the look of the real swap interface and push visitors to connect a wallet. They then ask the visitor to sign what looks like a routine swap or approval, but the transaction actually grants token spending rights or transfers assets to the attacker. Some versions also ask for a seed phrase under the pretext of a sync or fixing an error. Either way, the victim can lose whatever tokens the signed permission or exposed key reaches. The page now returns "Site not found · GitHub Pages", which shows the project has been removed, while our classification reflects the impersonation it hosted while it was active.

Evidence

On 2026-09-22, VirusTotal showed only 2 of 89 engines flagging the address, ChainPatrol and alphaMountain.ai. That is a thin count, but ChainPatrol focuses on crypto brand abuse, so its flag carries weight for this kind of lure. Stronger support comes from wallet-security lists. MetaMask and SEAL both block the domain alongside PhishDestroy, which means MetaMask users get a warning before they can interact with it.

Infrastructure

The page sits on a GitHub Pages subdomain, so there was no domain to register, and setting it up cost nothing and took minutes. Traffic resolves to Fastly, Inc. in the US, the content delivery network that serves GitHub Pages. That setup lets operators borrow a trusted platform address. It also means that one project removal takes the page down, which matches the short gap between first sighting on 2026-09-14 and the outage on 2026-09-21.

What to do

If you connected a wallet to this page, check for token approvals you did not intend and revoke them, especially unlimited allowances granted around mid-September 2026. If you typed a seed phrase into it, treat that wallet as compromised and move your remaining funds to a newly generated wallet immediately. Reach BaseSwap only through a bookmarked address or its official channels, not through search ads or links in direct messages. Defenders should block the hostname and watch for new github.io projects that use the BaseSwap name, then report them to GitHub and to crypto blocklist maintainers.

Questions about baseswap-app.github.io

Is baseswap-app.github.io legit?

No. PhishDestroy classifies baseswap-app.github.io as a Base impersonation page (risk: high, 68/100); it was first detected on 2026-09-14. VirusTotal: 2/89 engines flag it. Treat the site as unsafe.

Is baseswap-app.github.io safe to connect a wallet?

No. Do not connect a wallet, sign messages or approve tokens on baseswap-app.github.io. Phishing sites ask for approvals (approve, setApprovalForAll, Permit2) that let the operator move your assets, and a confirmed transaction cannot be reversed.

What should I do if I used baseswap-app.github.io?

Change every password you entered there and turn on two-factor authentication. If you connected a wallet or signed something, revoke the approvals and move the remaining funds to a new wallet; never share your seed phrase. Step-by-step help: emergency guide.

Recommendations & Advice for Victims

Choose the steps that match what you shared. Keep a copy of this report alongside your own records.

What should I do immediately?

Urgent

Stop using the suspicious site. Open the real service through its official app or an address you already trust.

  • Change all passwords — email, exchange accounts, anything that shares the same password
  • Enable 2FA using an authenticator app (not SMS). Disable SMS-based recovery
  • Freeze cards if you entered banking details on the phishing site

What information should I collect for my report?

FBI guidelines

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.
  • Exact dates & times — of each transaction and first contact with scammer
  • Screenshots — scam website, chat messages, emails, wallet transactions, social media
  • All URLs & domains used by the scammer (including baseswap-app.github.io)
  • Communications — emails, texts, phone numbers, usernames the scammer used

Even if you don't have all details — file a report anyway. Partial information still helps investigations.

Where should I report the scam?

  • FBI IC3 — Internet Crime Complaint Center (US federal reporting)
  • Europol — European cybercrime reporting (EU)
  • Your bank or payment provider — contact its fraud team promptly through official contact details if money or card information was exposed.
  • Local police — creates an official record, even if they can't act immediately

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?

  • Fake websites — pixel-perfect clones of legitimate sites with slightly altered domains
  • Pig butchering — trust built over weeks via Telegram/WhatsApp/dating apps, then money stolen
  • Recovery scams — fraudsters pose as recovery agents and demand upfront fees. Never share a seed phrase or pay before independently verifying the provider
  • AI-powered scams — deepfakes, automated phishing, and AI-generated sites making fraud harder to detect

How can I protect myself in the future?

  • Bookmark official sites — never click links from emails, DMs, or ads
  • Verify domains — check on PhishDestroy before interacting. Check HTTPS, spelling, domain age
  • "Too good to be true" = scam — guaranteed returns, celebrity endorsements, urgent deadlines
