Most Destin-area business owners think of a phishing attack as one bad moment. Someone on the team clicked a link, typed in a password or card number, and then caught the mistake. Everyone changes their passwords, a warning email goes around the office, and the business moves on. What most people never see is that the click is only the first step in a much longer process.

Your information enters a pipeline

The second someone submits their details on a fake login page, that information is sent to the attacker, often within seconds. It usually doesn’t get used right away. Instead it is bundled together with stolen details from thousands of other victims and sold in bulk on criminal forums.

These large batches are cheap because the data is raw and unchecked. Whoever buys it has no idea which logins still work, which passwords have already been changed, or which accounts are worth anything.

Someone sorts and verifies it

That is where a second group comes in. They test the stolen usernames and passwords against real services to see what still works. They check whether the same password was reused on other accounts, and they match the details against older data breaches to build a fuller picture of each person. The result is a cleaned-up, verified list that is worth far more than the raw batch, and it gets resold at a higher price.

Access is priced by how much it is worth. Logins for bank and cryptocurrency accounts sell for the most. Social media and messaging accounts go for less, but they are still traded in volume because they are useful for attacking the victim’s friends, coworkers, and customers.

The follow-up attack

Once a criminal buys a verified profile, the original phishing email barely matters anymore. They now know who the person is, where they work, which services they use, and they may be able to log into some of those accounts. That knowledge gets turned into targeted attacks: a convincing email that looks like it is from a manager, a message to one of your clients pretending to be your employee, or a demand for money backed by information pulled from a hacked account.

This is the part business owners almost never connect back to the original click. A password stolen from one Northwest Florida office this month can be the starting point for a business email compromise scam six months from now.

What to do if your business has been hit

The window to act is short, but the steps are simple.

• Any employee who entered a password on a suspicious site should change that password immediately, everywhere it was used, not just on the one account.
• If card or bank details were entered, cancel those cards rather than just watching the statements.
• Turn on two-factor authentication on every account that supports it, using an authenticator app instead of text-message codes where you can.
• Review which systems and accounts each staff member can reach, and cut back any access they no longer need. A stolen password is only as dangerous as what it unlocks.
