Know What Zero-Day Attack Is & How It Works

You protect your company’s files by making copies in case of compromise, but zero-day attacks hide before execution to corrupt all copies.
Zero-day attacks exploit vulnerabilities attackers discover before developers do and are delivered by email to infiltrate corporate networks.
When defending against zero-day attacks, knowledge is power, so Guardian Digital educates you on the six phases of a zero-day attack.
Watch: Anatomy of a Zero-Day Attack
Anatomy of a Zero-Day Attack
Phase 1: Looking for Vulnerabilities
Attackers search for vulnerabilities in code, experiment with popular applications, or purchase vulnerabilities on the black market.
Phase 2: Exploit Code Created
Cybercriminals create a malware program or other technical means to exploit the vulnerability they’ve found or bought.
Poorly written code, unencrypted data or weak password security are examples of exploited vulnerabilities.
Phase 3: Affected Systems Identified
Threat actors identify systems impacted by this vulnerability using methods such as bots or automated scanners.
Some software vulnerabilities may only impact Apple macOS, making Microsoft Windows and Linux users ineffective targets.
Phase 4: Planning
Attackers determine the best way to penetrate vulnerable systems, most often leveraging phishing campaigns to do so.
Phase 5: Infiltration
The malicious actors get through the perimeter defenses of an organization or personal device.
Phase 6: Attack Launched
Attackers are now able to execute code remotely on the compromised machine to steal sensitive data.
