"Is it worth it to report a cyber breach?"

Cybercrime reporting is how law enforcement, national cyber agencies, and industry partners connect patterns, disrupt campaigns, and issue faster warnings. The key is knowing where to report based on country and incident type.

What to Do After a Cyber Breach

  • If there’s immediate danger or risk of harm, call emergency services in your area

  • If money or accounts are involved, contact your bank or payment provider immediately

  • Preserve evidence: don’t wipe machines or delete emails; instead, collect screenshots, headers, logs, timestamps, and transaction IDs

  • Report using the correct national channel
