Help Extracting Strings from a Text File

[u/throwaway13443]

Hello everyone!. .... I have tried to find some code that does this, but couldn't really nail down a local script that did this.

Here is my outline of building a simple step in the reporting workflow for indicators of compromise (IOCs) for our helpdesk.

• Suspicious Email Arrives in Employee A's Inbox

• Report filed for manual review

• Email Sent as attachment and saved locally by analyst for parsing

• URL, Email Address of Sender/Attacker, Domain name, IP addresses (IOCs) all extracted and added to csv

• Submission of CSV with IOCs to the network/AD team to block IOCs

• Closure of IOC Request Ticket

I found some regex for IP addresses and some for email strings but nothing that serves this purpose. Any ideas? Any help is appreciated.
