Zero-Day Chrome exploits are cyberattacks that target unknown vulnerabilities in the Google Chrome browser. Attackers discover and exploit these vulnerabilities, often using methods like phishing. The recent #fantom hack serves as an example.

1. Discovery: Attackers find undisclosed vulnerabilities.

2. Targeting: Specific victims are chosen.

3. Exploitation: Malicious code is executed when victims visit compromised websites or open files.

4. Privilege Escalation: Attackers try to gain more control.

5. Data Theft or Further Attacks: Attackers steal data or launch more attacks.

The #fantom hack exploited a Chrome vulnerability, but the #fantom network itself was not compromised. Responsible disclosure and staying updated are key defenses.
