Fake Claude Max giveaway hides a Google account phishing trap
Brief
Phishing follows whatever people want at the moment, and right now that includes AI subscriptions they don’t have to pay for. We recently uncovered a new variation on this theme: A fake Claude Max giveaway that uses a convincing Google sign-in window to steal login information.
Claude’s paid plans start at $20 a month and cost considerably more for higher usage limits, while free accounts have stricter limits. That makes the promise of a free upgrade an attractive lure.
Microsoft reported in June that it had seen a growing number of phishing, malicious advertising, and search-based campaigns impersonating services such as ChatGPT, Claude, DeepSeek and Copilot. Some claim that a payment has failed and send you to a fake checkout. Others offer an app download that installs malware.
The campaign we found takes a different approach.
