A phishing campaign run through Google's ad network cost one Hyperliquid (HYPE) user $550,000, a security specialist said. Crypto security nonprofit Security Alliance (SEAL) flagged the same tactic in April, reporting it had blocked 356 malicious Google ad URLs across several weeks. The aggregate victim-side loss across those URLs remains unattributed.

The Hyperliquid loss

The $550,000 figure covers a single user's exposure, attributed by a security specialist. Google ads sit above organic search results, giving fraudulent placements a position that intercepts users before they reach the real site. No wallet address, specific date, or further breakdown of the attack chain appeared in available reporting beyond the Google ad vector and the dollar amount.

SEAL's April action

SEAL, a crypto security nonprofit, said in April it had identified and blocked 356 malicious URLs running through Google's advertising system over several weeks. That count is the supply-side measure. It reflects fraudulent ad placements removed, not the number of users successfully defrauded before those links came down.

What to watch

A full accounting of losses across the 356 URLs SEAL blocked would put a real number on the campaign's scale. The one documented case on Hyperliquid at $550,000 is the only victim-side figure in the record.
