How Vulnerable Is Your Small Business to Ransomware?

Most small business owners assume ransomware is someone else's problem. The data disagrees.

Ransomware, malicious software that locks you out of your own files and demands payment to get them back, used to be aimed primarily at hospitals, banks, and large corporations. Those are still targets. But attackers figured out something important: big companies have security teams, lawyers, and incident response plans. Small businesses usually have neither.

Over 60% of ransomware attacks now target small and medium-sized businesses. And roughly 60% of small businesses that suffer a serious cyberattack close within six months, not always because of the ransom itself, but because of the downtime, the recovery costs, and the reputational damage that follows.

You don't have to be a big target to be a target. You just have to be an easy one.

How Ransomware Actually Gets In

Phishing emails

The most common delivery method by a wide margin. An employee clicks a link or opens an attachment in what looks like a legitimate email: a shipping notification, a vendor invoice, a DocuSign request. The malicious software installs quietly in the background, sometimes waiting days or weeks before activating.

Remote Desktop Protocol (RDP) exposure

RDP is a built-in Windows feature that allows someone to remotely control a computer over the internet. It's genuinely useful for remote workers and IT support, and it's also one of the most actively scanned and attacked services on the internet. Businesses that leave RDP open to the internet without strong authentication are essentially leaving a door unlocked.

Unpatched software

When a security vulnerability is discovered in commonly used software, attackers move quickly to exploit it, often before the affected businesses even know the patch exists. Delayed updates create windows of opportunity that ransomware groups actively take advantage of.

Compromised credentials

If an attacker obtains a valid username and password, whether through a phishing attack, a data breach, or a credential-stuffing attempt, they can log in just like a legitimate user and deploy ransomware from the inside. This is one of the reasons MFA is so critical.

What Happens When Ransomware Hits

The experience is remarkably consistent across victims. You arrive at work, open your computer, and find that your files have been replaced with encrypted versions you can't open. There's a message on your screen explaining that you need to pay, usually in cryptocurrency, to receive the decryption key. Sometimes there's a countdown timer. Sometimes there's a threat to publish your data publicly if you don't pay.

What happens next depends almost entirely on whether you have a current, tested backup.

If you do, recovery is painful but survivable. You wipe the infected systems, restore from backup, investigate how it got in, and close the gap. You lose time. You may lose some recent data. But you recover.

If you don't have a backup, or your backup was also encrypted because it was connected to the same network, your options are grim. Pay the ransom and hope the attackers actually provide a working decryption key (they sometimes don't). Or start rebuilding from scratch.

The Moves That Actually Reduce Your Risk

• Back up your data, and keep one copy offline. A backup that lives on the same network as your primary files can be encrypted right along with everything else. The gold standard is called the 3-2-1 rule: three copies of your data, on two different types of storage, with one copy stored offsite or offline. Even a simple external hard drive kept disconnected from your network is dramatically better than nothing.
• Turn on MFA everywhere. Stolen credentials are only useful if the attacker can actually log in with them. MFA removes that possibility.
• Keep everything updated. Operating systems, browsers, office software, plugins: anything that connects to the internet should be kept current. Attackers target known vulnerabilities in outdated software because it's efficient.
• Have a plan before you need one. Knowing what to do in the first 30 minutes of a ransomware incident dramatically changes the outcome. Who do you call? Do you disconnect from the network? Do you have cyber insurance? Where's your backup? An incident response plan doesn't have to be long; it just has to exist.
