Summary

  • Scammers used cloned Uniswap interfaces in top Google Search ads to steal over $400K from users since late May.
  • SEAL research shows Uniswap-linked phishing sites comprised 41% of tracked crypto scams in March with similar attacks surging through March 30 2026.
  • Cointelegraph and multiple outlets urge verification of links through official channels.

Scammers stole over $400,000. They ran fake Uniswap ads on Google Search. The campaign began May 26.

Cloned interfaces sent users to phishing sites. Those sites drained wallets on contact. Two wallets collected most of the funds.

Reports tracked every transfer. The attacks reveal steady risks from paid ads in crypto.

Context

Google phishing attacks on crypto users rose sharply in March. The Security Alliance tracked duplicate ads from March 13 to March 30 2026. Uniswap sites formed a large share of the malicious domains.

This wave fits a pattern. Google ads scams exploit search visibility. Users hit sponsored results that lead to clones.

Details

The May 26 campaign placed fake Uniswap ads at the top of Google results. Victims connected wallets to the cloned sites. They lost assets at once.

"NEW: Scammers have pocketed at least $400,000 by running fake Uniswap phishing ads on Google Search. Always verify links through official channels."

, Cointelegraph (X)

SEAL researchers noted that Uniswap accounted for 41 percent of tracked malicious websites in March phishing campaigns. Sources including CryptoBriefing and CryptoRank confirmed the total drained exceeded $400,000 across multiple incidents.

No confirmation exists of direct platform liability from Google or Uniswap in these cases.

Reaction

Community discussions on X emphasized avoiding sponsored results entirely when accessing DeFi platforms. Multiple outlets repeated calls to manually enter official URLs rather than clicking ads.
