Picture a burglar standing in front of your office. He’s not carrying a crowbar. He’s carrying your key. He unlocks the front door, walks past the alarm panel, and lets himself into the file room. No broken glass, no tripped sensors, nothing for the security cameras to flag.<\/span><\/p>\n

That’s what most cyberattacks look like today. The majority of breaches don’t start with sophisticated code exploiting some obscure software flaw. They start with a valid username and password, typed into a real login screen, by someone who isn’t supposed to have it.<\/span><\/p>\n

If your business runs on Microsoft 365, Google Workspace, QuickBooks Online, or any cloud-based line-of-business app \u2014 and nearly every business in the Dayton area does \u2014 your login credentials are the front door. Here’s how attackers get the key, and how to change the locks.<\/span><\/p>\n

Where stolen passwords come from<\/b><\/p>\n

Attackers rarely “crack” passwords by guessing. They acquire them, usually in one of three ways.<\/span><\/p>\n

Data Breach Dumps<\/b><\/p>\n

When a big website gets breached, millions of email-and-password combinations end up for sale online. Attackers then try those same combinations everywhere else \u2014 a technique called credential stuffing. If your office manager used the same password for a retail site in 2021 that she uses for your payroll portal today, that password is likely already in circulation.<\/span><\/p>\n

Infostealer Malware<\/b>
\n<\/b>A quiet category of malware does nothing but harvest saved passwords, browser cookies, and session tokens from an infected computer, then ship them off to be sold in bulk. One bad download on one employee’s laptop can expose every account that person has ever logged into.<\/span><\/p>\n

Simply Asking<\/b>
\n<\/b>Fake login pages, urgent “your password expires today” emails, and phone calls from “IT support” still work. (We covered how to spot these in our recent post on convincing phishing emails \u2014 the point here is what happens *after* someone takes the bait.)<\/span><\/p>\n

Once an attacker has working credentials, everything they do looks legitimate to your systems. They read email, forward invoices, reset other passwords, and study your business quietly \u2014 often for weeks \u2014 before making a move like redirecting a customer payment or launching ransomware from the inside.<\/span><\/p>\n

Multi-Factor Authentication: The Single Highest-Impact Fix<\/b><\/p>\n

Multi-factor authentication (MFA) requires a second proof of identity \u2014 an app prompt, a code, or a physical key \u2014 before a login succeeds. A stolen password alone stops being enough.<\/span><\/p>\n

It is, dollar for dollar, the most effective security control a small business can deploy. Microsoft has estimated that MFA blocks the overwhelming majority of automated account-compromise attacks. It’s also increasingly non-negotiable: cyber insurance carriers now routinely require MFA on email and remote access before they’ll write or renew a policy.<\/span><\/p>\n

But not all MFAs are equal, and attackers have adapted:<\/span><\/p>\n
