When people picture a cyberattack they picture something loud. In practice the incidents that do real damage to small and mid-sized businesses are quiet: a password reused on a site that got breached two years ago, a mailbox rule silently forwarding invoices, a dormant account nobody remembered to remove after someone left.
The pattern is almost always the same
Credentials leak somewhere unrelated to you. Someone tests them against your email. They read quietly for a few weeks, learn how your invoices are worded and who signs them off, and then send one that looks exactly right.
What actually helps
Multi-factor authentication on everything that touches email or remote access. Monitoring that watches for the leaked credentials before somebody else uses them. Endpoint protection that flags the behaviour rather than waiting to recognise a known file. And a team that has seen a convincing fake invoice in training, so the real one is less of a surprise.
None of this is exotic, and all of it is cheaper than the alternative.
