How small business websites actually get hacked in 2026

Part 1 of 3 in our series on website security for business owners.

Most small business websites get hacked by automated programs, and nobody picked them out on purpose.

Attackers write software that scans millions of sites for one known weakness. If your site has it, you get hit. Your size and your industry don't matter much.

That's why the same few problems show up again and again. These are the five I'd watch for in 2026.

1. Software you forgot to update

Every website runs on software, even if you never see it. When someone finds a security hole in that software, the maker releases a fix. At the same moment, the hole becomes public. Attackers then go after every site that hasn't installed the fix.

This is now the most common way breaches start. Verizon's 2026 Data Breach Investigations Report found that known software holes started 31% of breaches. For small and mid-sized businesses, it was 26%. That's more than stolen passwords or phishing.

Attackers move fast, too. Patchstack, a WordPress security company, tracked the most heavily attacked holes in 2025. The typical gap between a hole going public and mass attacks was about five hours.

2. Stolen or reused passwords

Say you used one password for your website and an old shopping account. If that shopping site ever got breached, your password is probably on a list. Attackers buy those lists and test them on other sites automatically.

Verizon found that login details were stolen in 31% of small and mid-sized business breaches. With your login, an attacker doesn't need to break anything. They just sign in as you.

3. Scams aimed at people

This one costs businesses the most money. A common version is an email that looks like it came from your vendor. It says their bank details changed and asks you to pay the next invoice to a new account.

The FBI calls this business email compromise. In 2025, people reported 24,768 of these scams to the FBI. Reported losses came to just over $3 billion. Many victims never report, so the real number is higher.

AI makes these scams harder to spot. Scam emails used to have bad grammar. Now they read cleanly, and a cloned voice can sound like your boss on the phone. Businesses told the FBI they lost more than $30 million to these scams when AI was involved.

Texts and phone calls work even better for scammers than email. In Verizon's phishing tests, people fell for text and voice tricks 40% more often.

4. Code from other companies

Your site probably loads tools from other companies, like a booking widget or a chat bubble. Each one can change what your visitors see, and you don't control any of them.

Verizon found an outside company was involved in 55% of small and mid-sized business breaches.

Here's a real case. More than 100,000 websites loaded a free tool called polyfill.io. In 2024, a new owner bought it and changed the code. Some mobile visitors to those sites got sent to scam betting sites. Most of the site owners had no idea it was happening.

5. Your domain name

Your domain is the yourbusiness.com part of your web address. You manage it through an account with a company like GoDaddy or Squarespace. If someone gets into that account, they can point your address anywhere, including a fake copy of your site.

This happened in July 2024. Google had sold its domain business to Squarespace, and customers got moved over. Some moved accounts had no password set up yet and no two-step login. Attackers took over at least a dozen domains and pointed them at phishing sites. The real websites stayed untouched, but visitors landed on the fakes.

What happens after a break-in

The most common next step is ransomware. Attackers lock up your files and demand money to unlock them. Verizon found ransomware in 48% of breaches this year. It also says small businesses get hit by it more than their share.

Most of these problems have cheap fixes. The right fix depends on how your site was built, so part 2 goes through each type of site.
