The SOC team at CyberSecure Corp is conducting a security review to identify anomalous log entries from firewall logs. The team needs to extract patterns such as email addresses, IP addresses, and URLs to detect unauthorized access attempts, phishing activities, and suspicious external communications. The SOC analyst applies various regular expressions (regex) patterns to filter and analyze logs efficiently. For example, they use \b\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3}\b to match IPv4 addresses. Which regex pattern should the SOC analyst use to extract all hexadecimal color codes found in the logs?

A.

(0[1-9]|1[0-2])/(0[1-9]|(1[0-2])/[0-9]|3[01])\d{4}

B.

([A-Fa-f0-9]{6}|[A-Fa-f0-9]{3})

C.

[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+.[a-zA-Z]{2,}

D.

\b\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3}\b
