Top 5 Email Threats You Didn’t Know Were Hiding in Your Inbox
Let’s face it—email is the lifeblood of modern business. But behind every “urgent” subject line or familiar sender name, there could be something much more sinister lurking. At ExchangeDefender, we spend our days defending inboxes against threats most people don’t even know exist. So today, we’re spilling the secrets. Here are 5 sneaky email threats that could be hiding in plain sight:
1. Lookalike Domains (a.k.a. Evil Twins)
These emails come from addresses that look legit—maybe a single letter off from your CEO’s real email, or a domain that’s cleverly misspelled.
Why it’s dangerous: They’re made to trick you into clicking links or wiring money.
How we stop it: ExchangeDefender uses advanced domain and sender verification to block imposters fast.
2. Zero-Day Attachments
These are brand-new threats that haven’t even made it to antivirus databases yet. They come disguised as invoices, resumes, or project files.
Why it’s dangerous: Traditional filters might miss them.
How we stop it: Real-time scanning and sandboxing help catch unknown threats before you open them.
3. Credential Harvesting Links
Not all phishing scams are loud and obvious. Some hide in the form of password reset requests or shared documents.
Why it’s dangerous: One click can expose your login—and open the door to your entire system.
How we stop it: Link analysis and real-time URL scanning keep you protected, even from shortened or masked links.
4. Conversation Hijacking
Hackers insert themselves into real email threads and respond like they’re part of your team. Creepy, right?
Why it’s dangerous: You’re more likely to trust something that feels familiar.
How we stop it: Behavioral monitoring flags unusual responses—even when they happen mid-thread.
5. Impersonation of Internal Staff
Ever get a weird request from “Accounting” or “HR”? Sometimes, attackers mimic your internal teams to request sensitive info or payments.
Why it’s dangerous: These attacks rely on trust and internal knowledge.
How we stop it: ExchangeDefender uses AI and policy enforcement to detect when internal communication doesn’t add up.
So, What Can You Do?
Well, you already did the first step: you’re here. 🧠👏
The next step? Put a solution like ExchangeDefender Email Security between your team and the bad guys. We’re built to detect, block, and neutralize all of these threats—before they hit your inbox.
Because email should be for collaboration, not chaos.

Understanding Email Headers: How to Detect and Prevent Email Spoofing
Email Spoofing is a deceptive tactic where attackers forge email headers to make messages appear as if they originate from trusted sources. This technique is commonly used in phishing attacks to deceive recipients into revealing sensitive information or downloading malicious software. Understanding how to analyze email headers can help you identify and protect against such fraudulent activities.
What Are Email Headers?
Email headers are essential components of an email message that contain vital information about its origin, route, and authenticity. They include fields such as ‘From’, ‘To’, ‘Subject’, ‘Date’, and several others that provide a trail of the email’s journey from sender to recipient. While some of these fields are visible in your email client, many are hidden and can be viewed by accessing the email’s source or original message.
How to Access Email Headers:
- Outlook: Open the email, click on “File,” then “Properties,” and view the “Internet headers” box.
- Gmail: Open the email, click on the three vertical dots next to the reply arrow, and select “Show original.”
- Yahoo Mail: Open the email, click on the three horizontal dots, and select “View raw message.”

Key Email Header Fields to Examine:
- From: Indicates the sender’s email address. However, this field can be easily forged and should not be solely relied upon to verify the sender’s identity.
- Reply-To: Specifies the email address to which replies should be sent. Discrepancies between the ‘From’ and ‘Reply-To’ addresses can be a red flag for spoofing.
- Received: Shows the servers that handled the email during its transmission. By examining the sequence of ‘Received’ fields, you can trace the path the email took and identify anomalies.
- Return-Path: Indicates where non-delivery receipts (bounces) are sent. A mismatch between the ‘Return-Path’ and ‘From’ addresses may suggest spoofing.
- Received-SPF: Displays the result of the Sender Policy Framework (SPF) check, which verifies if the email comes from an authorized server. A ‘Fail’ or ‘Softfail’ status can indicate potential spoofing.
Detecting Spoofed Emails:
- Examine the ‘Received’ Fields: Trace the email’s path by reviewing the ‘Received’ fields. Inconsistencies or unfamiliar server names can be indicators of spoofing.
- Check SPF, DKIM, and DMARC Results: These authentication mechanisms help verify the legitimacy of the email. Failures or absence of these checks can be warning signs.
- Analyze the ‘Return-Path’ and ‘Reply-To’ Fields: Ensure these fields match the ‘From’ address and are consistent with the sender’s domain.
- Use Email Header Analysis Tools: Online tools like MxToolbox’s Email Header Analyzer can simplify the process by parsing headers and highlighting issues.
By understanding and analyzing email headers, you can better detect and prevent email spoofing attempts, thereby safeguarding your personal and organizational security. Need extra security? Try ExchangeDefender PRO for free!
Are the BCBS settlement emails legit?
The recent Blue Cross Blue Shield (BCBS) settlement has led to a wave of emails notifying individuals about potential compensation. While many of these messages are legitimate, cybercriminals are using this as an opportunity to launch phishing scams. Here’s what you need to know to protect yourself.
What Is the BCBS Settlement?
BCBS agreed to a $2.67 billion settlement in an antitrust lawsuit alleging the company engaged in anti-competitive practices. Individuals or entities that had BCBS health insurance or administrative services between February 2008 and October 2020 may be eligible for compensation.
The official settlement administrator has been sending notifications via email and mail. Legitimate emails come from Notice@BCBSsettlement.com, and the official website is www.BCBSsettlement.com.
How Scammers Are Exploiting the Settlement
Cybercriminals are taking advantage of this widespread settlement by sending fraudulent emails that:
- Contain suspicious links, such as those prompting users to “request an electronic debit card”
- Use convincing BCBS logos and branding to appear legitimate
- Request personal or financial information
Users on forums like Reddit have reported phishing attempts disguised as official settlement notifications. Clicking on these fake links can lead to identity theft, malware infections, or financial fraud.
How to Protect Yourself
- Verify the Sender – Legitimate emails will come from Notice@BCBSsettlement.com.
- Avoid Clicking Links – Instead of clicking email links, visit the official website directly by typing www.BCBSsettlement.com in your browser.
- Contact the Official Source – If you’re unsure, reach out to the settlement administrator via info@BCBSsettlement.com or call (888) 681-1142.
- Use Email Security Solutions – A robust security tool like ExchangeDefender PRO can help filter out phishing emails before they reach your inbox.
Stay One Step Ahead with ExchangeDefender

How the eBay Phishing Scam Works
The eBay phishing scam is a common cyberattack where scammers impersonate eBay to steal user credentials, financial details, or personal information. These scams often take the form of fake emails, text messages, or websites designed to trick users into providing sensitive information.
In eBay phishing scams, attackers send counterfeit emails or messages that appear to originate from eBay. These communications often contain urgent prompts, such as warnings about account issues or unauthorized transactions, compelling recipients to click on malicious links. These links lead to fake websites resembling eBay’s login page, where users are tricked into entering their credentials. Once obtained, cybercriminals can exploit this information for fraudulent activities, including unauthorized purchases or identity theft.
Red Flags to Watch Out For:
🚨 Generic Greetings – Legitimate eBay emails usually address you by name. Look for fake logos!
🚨 Suspicious Links – Hover over links before clicking—real eBay links should start with “ebay.com.”
🚨 Poor Grammar & Spelling – Many phishing emails have obvious errors. Look for fake phone numbers!
🚨 Requests for Personal Info – eBay never asks for passwords, payment info, or security details via email.
How to Protect Yourself:
✅ Enable Two-Factor Authentication (2FA) for extra security.
✅ Go Directly to eBay – Instead of clicking links, log in at eBay.com.
✅ Report Suspicious Emails to eBay at spoof@ebay.com.
✅ Use Strong, Unique Passwords – Avoid reusing your eBay password on other sites.

How to Spot and Avoid Geek Squad Email Scams
In recent years, scammers have increasingly impersonated Geek Squad, Best Buy’s tech support service, to deceive individuals into divulging personal information or making unnecessary payments. Understanding how these scams operate and how to recognize them is crucial for safeguarding your personal data and finances.
Understanding the Geek Squad Email Scam
The Geek Squad email scam is a phishing attempt where fraudsters pose as Geek Squad representatives to steal personal information or trick victims into paying for fake services. These emails often appear legitimate, making it challenging to distinguish them from authentic communications.
Common Types of Geek Squad Email Scams
- Auto-Renewal Scam: Scammers send emails stating that your Geek Squad subscription is about to auto-renew at a substantial cost. The email urges you to call a provided number or click a link to cancel the subscription, aiming to extract personal and financial details.
- Fake Antivirus Software Offer: You might receive emails warning of malware infections among Geek Squad customers, offering free antivirus software downloads. However, these downloads are malicious and designed to infect your device, steal data, or gain remote access.
- Password Reset Scam: Emails claim suspicious activity on your Best Buy account, prompting you to reset your password via a provided link. The link leads to a fake website designed to capture your login credentials, allowing scammers unauthorized access to your account.
Recognizing Scam Emails
Be vigilant for the following signs:
- Sense of Urgency: Scammers often pressure you to act quickly, creating a false sense of urgency.
- Suspicious Sender Addresses: Examine the sender’s email address for inconsistencies or misspellings. Official communications will come from a legitimate Best Buy domain.
- Generic Greetings: Emails that don’t address you by name, such as “Dear Customer,” may be fraudulent.
- Poor Grammar and Spelling: Legitimate companies maintain professional communication standards.
- Unsolicited Attachments or Links: Avoid clicking on links or downloading attachments from unknown senders.
Protective Measures
- Verify Communications: If you receive a suspicious email, contact Geek Squad or Best Buy directly using official contact information from their website.
- Avoid Unsolicited Links and Downloads: Refrain from clicking on links or downloading attachments from unknown sources.
- Use Security Software: Ensure your devices are equipped with reputable antivirus and anti-malware programs.
- Stay Informed: Educate yourself about common phishing tactics to recognize and avoid potential scams.

Avoid Netflix Payment Scams: Recognize Phishing Emails

These phishing emails closely mimic legitimate Netflix communications, making them particularly deceptive.

How the Scam Operates
Victims receive emails claiming issues with their Netflix account, such as payment problems or account suspensions.

- Urgent Language: The message may claim your account is on hold and prompt immediate action to update payment information.
- Suspicious Links: Hovering over links may reveal URLs that don’t direct to Netflix’s official website.
Protective Measures
- Avoid Clicking Links: Do not click on links or open attachments from unsolicited emails.
- Verify Authenticity: Log in directly through the official Netflix website to check your account status.
- Report Suspicious Emails: Forward any dubious emails to phishing@netflix.com.
- Monitor Financial Statements: Regularly check your bank and credit card statements for unauthorized transactions.
Netflix’s Official Stance
Netflix states it will never ask for personal information, such as credit card numbers or passwords, via email or text messages. By staying vigilant and recognizing the signs of phishing attempts, you can protect your personal and financial information from these scams.
