Keep Your Business Safe from Email and Calendar Phishing Attacks

As a small business, you’re often juggling a million things at once – and cybercriminals know it. That’s why phishing emails and malware-laced calendar invites are becoming increasingly common. These threats are designed to catch you off guard and trick you or your team into clicking links, downloading malicious files, or sharing sensitive information.

At O’Brien Media, we’re passionate about helping businesses stay safe online. So here are some essential tips to help you and your team spot the warning signs — and avoid falling victim to phishing and malware attacks.

Email Phishing: What to Watch For

Phishing emails can be deceptively convincing. They might look like they’re from a supplier, a customer, or even one of your team members – but there are always clues.

Red flags to watch:

• Unexpected emails with attachments or links – even from someone you know.
• Urgent or threatening language, like “your account will be suspended” or “action required immediately.”
• Poor grammar and typos, or strange formatting.
• Email addresses that look almost right, but are slightly off (e.g. [email protected]).

If something seems even a little suspicious, don’t click — and don’t reply. Confirm it using a different method, like a phone call or separate email chain.

Calendar Invites Can Be Traps Too

It’s not just your inbox that’s under attack – cybercriminals are now sending fake calendar invites, often with malicious links or file attachments.

Stay safe by:

• Not accepting calendar invites from unknown senders.
• Double-checking with the sender if something feels odd or unexpected.
• Never clicking links or downloading files from suspicious invites.

Five Quick Tips to Stay Cyber-Safe

• Verify before clicking: Always double-check unexpected messages.
• Don’t send passwords or personal info by email or chat.
• Use strong, unique passwords – and a password manager if possible.
• Turn on Two-Factor Authentication (2FA) where available.
• Keep your software up to date and restart your device when prompted.

What to Do If You’re Not Sure

If something seems suspicious, trust your instincts. Forward the email or invite to your IT contact or an external expert (we’re always happy to help if you’re unsure) before taking any action.

What To Remember

Phishing attacks and malware scams aren’t just a problem for big companies – small businesses are often easier targets. But with a bit of awareness and some simple precautions, you can protect yourself, your team, and your customers.
