Every day, businesses and individuals receive fraudulent emails designed to steal money, personal information, or access to computers. At TMD Technology Services, we see these phishing attempts regularly. Many follow predictable patterns: fake antivirus invoices, unexpected credit card charges, package delivery notifications, and urgent account verification requests.
The goal is to make you panic and react before thinking. With holiday shopping and travel approaching, criminals know you’re expecting more receipts, packages, reservations, and confirmations than usual.
Fake Invoices and Antivirus Renewal Scams
One of the most common scams we see is a fake invoice claiming your credit card was charged hundreds of dollars for antivirus software or a security subscription you never purchased. The message may include a PDF receipt, recognizable logo, and a telephone number to call for a refund.
The invoice is fake, and the phone number connects you to scammers. They may ask for credit card or banking information to supposedly reverse the charge, or tell you to install software so they can remotely access your computer.
If you don’t recognize the invoice, don’t panic. Never call the number in the suspicious message. Instead, open your bank or credit card’s official app or website directly and review your transactions. If there is no charge, that strongly suggests the receipt is fraudulent. If there is an unfamiliar charge, contact your financial institution through a verified channel.
Holiday Shopping and Package Delivery Scams
Holiday purchases, gifts, hotel reservations, flights, and deliveries create opportunities for scammers. Fraudulent messages may impersonate Amazon, UPS, FedEx, or USPS and claim that your package is delayed, your address needs verification, or you owe a small delivery fee.
Don’t click tracking links in unexpected messages. Open the retailer’s official website or app to check your order, or enter a known tracking number directly on the shipping carrier’s website. A familiar logo doesn’t prove an email is genuine.
Beware of QR Code Phishing
Some phishing emails use QR codes instead of clickable links. They may ask you to scan a code to view an invoice, confirm a delivery, update payment details, or verify Microsoft 365 access. The code can lead to a fraudulent website designed to capture your passwords or financial information.
Never scan QR codes in unexpected or suspicious emails.
Never Give Strangers Remote Access to Your Computer
Scammers posing as billing or support representatives may ask you to install remote-access software to process a refund. Once connected, they may access sensitive files, email, saved credentials, or business systems. A routine refund does not require unrestricted access to your computer.
If you’ve already granted suspicious access, disconnect the device from the internet and contact your trusted IT provider immediately.
Seven Simple Rules to Avoid Phishing Scams
- Treat unexpected emails as suspicious until verified. Sender names and logos can be impersonated.
- Don’t open unexpected attachments. Especially invoices and receipts you weren’t expecting.
- Never call numbers supplied in suspicious messages. Find verified contact information independently.
- Don’t click unfamiliar links or scan unexpected QR codes. Go directly to official websites and apps.
- Never provide passwords, banking details, or credit card information in response to an unsolicited message.
- Don’t reply to suspicious emails. Delete or report them instead.
- When in doubt, ask your IT provider. A quick check is easier than recovering from a compromise.
Don’t panic. Scammers rely on fear and urgency to get you to make mistakes.
What If the Email Comes From Someone You Know?
Criminals sometimes compromise real email accounts and send fraudulent messages to the victim’s contacts. Even a familiar sender is not proof a message is safe. If an invoice or document request seems unusual, verify it through a separate trusted channel, using a number you already have on file.
Businesses Need More Than Common Sense
Employee awareness matters, but businesses also need layered defenses. Email threat protection, endpoint security, monitoring, and responsive IT support can help reduce exposure to malicious links, attachments, and impersonation attempts. No solution blocks every phishing message, so employees must know how to recognize and report suspicious activity promptly.
Stop, Think, and Verify
Whether it’s a $499 antivirus renewal, a missed FedEx delivery, an unexpected Amazon purchase, or an urgent Microsoft 365 verification request, take a moment before responding. You don’t need to answer every email, call every phone number, or follow instructions from strangers.
A little common sense and a few seconds of independent verification can prevent a very expensive mistake.
