Every business with a website – even a small booking form or contact page – is a potential target. Attackers don’t hand-pick victims; they run automated tools that scan the entire internet for a handful of well-known weaknesses, and strike wherever they find one. A recent breakdown from freeCodeCamp lists the techniques behind most break-ins, and the pattern is clear: these are old, well-understood problems that keep working because basic fixes get skipped.
The list includes tricks like SQL injection (feeding a form malicious text to trick a database into handing over data), cross-site scripting (planting a script that runs in a visitor’s browser to steal their login session), and simply changing a number in a web address to view someone else’s invoice or order – a flaw called an insecure direct object reference. Others are just poor housekeeping: default admin passwords never changed, error messages that leak technical details, data sent without encryption, or software plugins left outdated and unpatched for months.
This isn’t a shrinking problem either – security researchers reported that AI-assisted scanning tools helped drive a record surge in vulnerability disclosures in June 2026 alone, with roughly 1,500 high-severity flaws reported by major organisations in a single month. More weaknesses are being found, faster, than ever.
You don’t need to be a developer to close most of the gaps. Three practical steps:
- Keep everything updated. Website platforms, plugins, and themes should be patched as soon as updates are available – most real-world break-ins exploit known, already-fixed bugs.
- Use strong, unique logins and HTTPS everywhere. Change default admin credentials immediately, add multi-factor authentication where you can, and make sure your whole site runs on HTTPS, not just the checkout page.
- Get an independent check. Most business owners never audit their own site’s security until something goes wrong – a periodic outside review catches misconfigurations and forgotten admin panels before an attacker does.
