API TigerAI App

The API TigerAI App (accessed via api.tigerai.app) is identified as a browser hijacker/adware disguised as a legitimate API portal. It lacks affiliation with the authentic Tiger Brokers platform and uses deceptive invite links on social media to entice users.

In-Depth Analysis

How did I get infected?

Users are typically lured via phishy invite links circulated on platforms like Telegram, Facebook groups, and YouTube, promising exclusive access or crypto airdrops. These are not official Tiger Brokers promotions and carry hidden scripts that hijack browser behavior.

What does it do?

Once you click the link:

• You’re redirected away from trusted domains.
• The site asks for access to notifications or browser permissions.
• Ads and pop-ups appear across unrelated sites.
• Any login or data entry forms may harvest credentials or financial details.
• The experience is unencrypted (HTTP-only), making data interception easier.

Should you be worried?

Yes. While not classified as ransomware or a system-damaging threat, its main danger lies in privacy invasion and phishing. If you entered details believing it to be official, you may be vulnerable to identity or financial theft.
