Here’s a scenario we want every Chicagoland leader to think about:
What if someone got hold of one of your employee’s passwords from years ago?
Not a password they use today. Not one they even remember. Just an old login that never got changed, and still works.
That “old password” situation is one of the quiet ways modern incidents start. A recent investigation into a large-scale data theft campaign found that sensitive business data from many organizations was collected quietly and later offered for sale. Different industries. Different countries. Different company sizes.
But one weakness kept showing up again and again.
People could sign into important cloud systems with only a username and password. No second step. No extra check. Just type it in and you’re in.
MFA is the simple control that breaks a lot of real attacks
Multi-factor authentication (MFA) means using more than one signal to prove it’s really you. Usually that’s a password plus something else, like:
An approval prompt on your phone
A code from an authenticator app
A hardware key
Biometrics
So even if someone steals a password, it’s not enough to get in.
And in this campaign, MFA was not enforced. Stolen passwords still worked.
How attackers get passwords without “hacking” your firewall
Many of these campaigns rely on infostealing malware. That’s malicious software that can end up on a device without the person noticing. Once it’s there, it quietly collects saved passwords and login details and sends them back to criminals.
This does not only happen on office machines. It can happen on home devices, personal laptops, or any computer that has ever been used to sign into work systems.
Then the credentials get traded, bundled, sold, and reused.
The part that makes this scarier: time does not protect you
One of the more uncomfortable details from this campaign is that some of the passwords used were reported to be years old.
That points to two common issues:
Passwords were not being changed often enough
Old logins were still being trusted long after they should have been invalidated
In other words, a device that was compromised a long time ago can become a serious problem today, because the credential is still valid.
Security teams sometimes call this a latency problem. The risk sits quietly in the background, waiting for the right opportunity. Time passing does not make it safe.
MFA turns stolen credentials into a dead end
In the cases above, attackers had the password. They did not have the second factor.
No phone prompt. No code. No approval tap.
That one extra step would have forced a stop. And that is why MFA is a baseline now, especially for email and identity systems that can lead to business email compromise.
“MFA is annoying” is real. So is the alternative.
Yes, MFA adds a moment to the login process.
But compare that to what happens when an old credential still works years later. Confidential files can be copied. Mailboxes can be accessed. Invoices can be rerouted. Client trust can take a hit. And you may not notice until the damage is already done.
MFA does not solve every problem, but it does something very practical:
It makes stolen passwords far less useful.
If you want this to stick, pair MFA with two simple moves
If you’re tightening access for a Chicago-area team, MFA is step one. Two quick add-ons make it much more effective:
Make reporting easy. Add a report phishing button and tell staff exactly what “suspicious” looks like in your environment. Short reminders beat long trainings.
Know what you’ll do in the first hour. When an account looks compromised, speed matters. A simple first-hour checklist after a cyber incident keeps the response calm and consistent.
One takeaway for Chicagoland leaders
Old passwords do not expire on their own. Old logins do not clean themselves up. And criminals are patient.
MFA is not overkill anymore. It’s sensible.
If you want help enforcing MFA across your cloud apps and email, plus making sure your response plan is clear, get in touch.
