This multiline PCRE pattern matches entire lines containing the literal text 'SIM ICC Id', then captures the tail end of the identifier — specifically at least the last 6 word characters — into a capture group. With the global flag, it's commonly used in Splunk SEDCMD to mask SIM ICC IDs by replacing everything except the captured last 6 characters, hiding sensitive data while retaining a partial value for troubleshooting.
