vaultkarewards.pages.dev is an impersonation phishing page built for the Arbitrum DeFi crowd. It presented itself as "Vaultka - The Catalyst of Perpetual Exchanges on Arbitrum", and the "rewards" in its name points at users hoping to claim incentives. PhishDestroy first flagged it on 2026-09-05. The site has been offline since 2026-09-16 after the hosting provider blocked its content, and it was still dead at the last check on 2026-10-19.
How the scam works
The page copies the branding of a perpetual-exchange project on Arbitrum and wraps it in a rewards promise, so visitors expect to connect a wallet and collect something. Pages of this type then ask the visitor to approve a token allowance or sign a message that hands spending rights over their assets to the operator, and the wallet is emptied once that signature goes through. The page title carries Vaultka branding, while our classification records Arbitrum as the impersonated brand.
Evidence
Six of 89 VirusTotal engines flagged the domain at the 2026-09-17 check: alphaMountain.ai, BitDefender, Forcepoint ThreatSeeker, G-Data, Gridinsoft and Webroot. That is a modest share, so many browsers and security products would not have warned visitors on their own. The crypto-specific lists filled that gap. ScamSniffer and Enkrypt block it alongside PhishDestroy, which matters because those lists protect users at the wallet level, right when a signature is requested.
Infrastructure
The subdomain was created on Cloudflare Pages on 2026-09-04, and PhishDestroy caught it the next day. That timing fits a throwaway page set up to run briefly before anyone noticed. It was served from Cloudflare's network with a Canadian geolocation. Its Google Trust Services certificate came automatically with the platform, so the padlock said nothing about who was behind the page.
What to do
If you connected a wallet to this page and signed anything, revoke every approval granted around that time using a token-approval checker, then move any remaining funds to a fresh wallet. If you typed in a seed phrase, treat the wallet as compromised and transfer what is left right away. To check Vaultka or Arbitrum rewards, go only through the projects' official channels, never through a link someone sent you. Defenders should block the domain and watch for similar lookalike subdomains on free hosting platforms that pair DeFi project names with words like rewards or claim.
