Zero-day attacks that exploit unknown or unaddressed vulnerabilities enable cybercriminals to infiltrate corporate networks and either attack immediately or sit and wait for the optimal time to do so. The majority of zero-day attacks are carried out via email.
Anatomy of a Zero-Day Attack
A zero-day attack typically follows six distinct phases:
Looking for Vulnerabilities
Attackers search for vulnerabilities in code, experiment with popular applications, or purchase vulnerabilities on the black market.
Exploit Code Created
Cybercriminals create a malware program or other technical means to exploit the vulnerability they’ve found or bought.
Affected Systems Are Identified
Threat actors identify systems impacted by this vulnerability using methods such as bots or automated scanners.
Attackers determine the best way to penetrate vulnerable systems, most often leveraging phishing campaigns to do so.
The malicious actors get through the perimeter defenses of an organization or personal device.
Attackers are now able to execute code remotely on the compromised machine to perform malicious actions such as stealing sensitive data that can be monetized for personal gain.

Safeguards the Inbox against Zero-Day Attacks
Zero-day attacks are becoming increasingly prevalent and problematic for all organizations. Small businesses are at heightened risk, as these companies often have less stringent technological defenses, less awareness of threats and less time and resources to invest in protection. Small businesses have the most to lose, and cyberthieves are readily exploiting these weaknesses in dangerous zero-day attacks.
Guardian Digital keeps SMBs and enterprises alike ahead of the latest zero-day threats identified worldwide with adaptive defenses that are updated in real-time, enabling them to evolve as quickly as these zero-day attacks themselves.
