Clicking on the link and attempting to sign in can lead to the theft of sensitive personal information or installation of malware on your device.

How to Spot and Handle Error Email Scams?

We all get a little anxious when we see an email delivery failure notice. Did my important email not go through? Who didn't get my message? What went wrong?

Cybercriminals know exactly how we react to these situations, and they are actively exploiting it. Recently, we intercepted a sophisticated phishing email targeting our team that pretends to be a system "bounce" or "recipient error" notification.

Because these emails look like automated system logs, they can easily slip past our mental defences. To keep our network secure, let’s break down exactly how this scam works, examine a real-world example, and review the golden rules for handling them.

Bounce Recipient Error Email Scam.

At first glance, it looks like an automated IT notification, however when you look closer, the red flags show immediately.

The Two Major Red Flags.

When evaluating any suspicious email, you don't need a degree in cybersecurity to spot a fraud. You just need to look for two glaring inconsistencies that were perfectly highlighted in this specific attack:

Red Flag #1: You Don’t Use the Named Service.

The email claims there is an issue retrieving messages from a specific server or service. Ask yourself: Do I actually interact with this platform or use this specific setup? If a notification pops up for an account, service, or system migration you have never heard of or don't actively manage, stop right there. Legitimate automated systems don't send random errors to people who aren't using them.

Red Flag #2: The Sender Address Mismatch.

Look closely at the "From" line: mail_delivery <ews@bizitpay.com>.

If this were a legitimate notification from our actual mail server or internal IT infrastructure, it would come from our own domain or our official email provider. Instead, it comes from @bizitpay.com, a completely unrelated third-party domain that has nothing to do with us. Attackers constantly forge names like "mail_delivery" or "IT Support," but they often cannot hide the strange, unrelated email addresses sitting inside the brackets.

 What This Scam Is Trying to Achieve?

This specific attack is a form of forged-bounce phishing (sometimes related to email "backscatter").

1. The Setup: The attackers create an email that looks exactly like a delivery status notification (DSN).
2. The Bait: They tell you that you have pending messages or that an email failed to send, and they provide a link to "Preview" the message or "View the complete list."
3. The Trap: If you click that link, you aren't taken to an email server. Our URL checkers rated this link as "Definitely Don’t Go There — Not Safe." The link actually points to a compromised, unrelated website (in this case, a hijacked German website: fahrschule-christoph-roth.de).

If you follow that link, you will likely be met with a fake login page designed to look exactly like Microsoft 365, Google Workspace, or our company portal. The moment you type your username and password to "view the email," the scammers steal your credentials.

 Your Action Plan: What To Do If You Receive This?

Security is a team effort. If an email like these lands in your inbox, follow these steps immediately to protect yourself and the company:

• Do Not Click Any Links: Do not try to "preview" the message or click the "tips" links.
• Do Not Reply to the Email: Replying to the message, even to tell them off, confirms to the scammers that your email address is active and monitored by a real person. This will only lead to more spam and targeted attacks.
• Verify Independently (If Unsure): If you are genuinely worried that an email failed to send, do not rely on the notification link. Go to your Sent Items folder. If you didn’t send a message at that specific time, the bounce error is completely fake.
• Report It Immediately: Forward the email directly to our IT/Security team so we can update our central firewalls and block the malicious domains across the whole company.
• Delete It: Once reported, delete the email from your inbox and clear your deleted items folder.

 What are Practical Daily Habits for Email Safety?

To stay sharp against these evolving tactics, keep these quick tips in mind every time you open your inbox:

What to Check	What to Look For
The "From" Field	Don't just look at the display name. Look at the actual email address inside the < > brackets to ensure it matches who they say they are.
Link Destinations	Hover your mouse over any link before clicking it. Look at the bottom corner of your screen to see the real URL destination. If it doesn’t match the text in the email, don't trust it.
Urgency & Errors	Be deeply suspicious of emails demanding immediate action due to an "error," "account suspension," or "expired password."

 What to Do If You Already Clicked?

We are all human, and these scams are designed to be highly convincing. If you accidentally clicked a link in a suspicious email, or worse, if you entered your password on a page you think might be fake, time is of the essence.

1. Disconnect: Disconnect your device from Wi-Fi or unplug your network cable immediately to stop potential malware from spreading.
2. Notify IT Urgently: Contact the IT department immediately via phone or a separate messaging channel.
3. Change Your Password: From a known clean device, change your corporate password immediately and ensure your Multi-Factor Authentication (MFA) settings haven't been altered.
