Suspicious Link - "When in doubt, don't click out."

"Links are risky because they can take you to dangerous websites. These websites can send malicious instructions to your computer without your input. You should never click on a suspicious link under any circumstances."

In today’s digital landscape, cybercriminals constantly innovate to bypass our defenses, with phishing and malicious links leading the charge. Recognizing suspicious links and attachments isn’t just for IT—it's a critical skill for everyone.

?? Key Technical Tips for Spotting Suspicious Links and Attachments:

1. Hover, Don’t Click ??? – Hover over links to reveal their full URL, especially if they’re hidden behind text like “Click Here.” Verify the domain carefully, as attackers use minor alterations (e.g., "micros0ft.com" instead of "microsoft.com").
2. Look Out for HTTPS ?? – Ensure URLs begin with “https://” rather than “https://.” While HTTPS alone doesn’t guarantee safety, the absence of it is a red flag.
3. Check Shortened URLs ?? – Attackers often use link shorteners (like bit.ly) to hide malicious links. Use preview tools like CheckShortURL to expand and verify shortened links before clicking.
4. Understand MIME Types for Attachments ?? – Many email clients can preview file types, but some malicious files are disguised with misleading names. Right-click and check file properties or use file inspection tools to validate extensions, especially for files like .iso, .jar, or .scr.
5. Leverage Sandboxing ??? – For advanced users, sandboxing tools like Firejail or Sandboxie can isolate suspicious files in a virtual environment, so you can examine them without risking system compromise.
6. Enable Advanced Email Security Settings ?? – Many platforms offer security filters like SPF, DKIM, and DMARC. Enabling these adds an extra layer of verification, reducing the chances of receiving spoofed emails.
7. Apply Multi-Factor Authentication (MFA) ?? – If you accidentally interact with a suspicious link, MFA can prevent unauthorized access to accounts by requiring a second verification step.

?? Example 1: Phishing Link in an Email

Email Preview Subject: "Important Update: Confirm Your Account Now" Message: "Dear User, please confirm your account by clicking the link below. Failure to do so within 24 hours will result in account deactivation. Click here to confirm"

Red Flags:

• Misspelled URL: The “o” in “microsoft” is actually a “0” (zero).
• Unsecured Link: The URL uses "https://" instead of "https://".
• Urgency Tactic: Cybercriminals often pressure users with phrases like “24 hours” or “immediate action required.”

What to Do:

• Hover Over the Link: See if the actual URL matches the official domain.
• Verify by Going Directly to the Site: Don’t click; open a new tab and type in the official Microsoft site manually.

?? Example 2: Suspicious Attachment in an Email

Email Preview Subject: "Urgent: Invoice Attached for Review" Attachment: invoice_details.scr

Red Flags:

• Unexpected Attachment Format: .scr files are screen saver files and are not typical for invoices (usually .pdf or .docx).
• File Name Trick: Some malware hides behind legitimate-sounding names like “invoice” or “payment details.”

What to Do:

• Check the File Extension: Don’t open unusual formats like .scr, .exe, .js, or .iso.
• Verify the Sender: Confirm with the sender directly if you were not expecting an invoice.

?? Example 3: Shortened URL in a Text Message

Text Message Preview “Your package is delayed. Track your shipment here: [bit.ly/3DxgTR5]”

Red Flags:

• Use of a Shortened URL: This hides the actual website, commonly used to obscure malicious links.
• Out-of-the-Blue Message: If you didn’t order a package, this is likely a phishing attempt.

What to Do:

• Preview the Shortened Link: Use a service like CheckShortURL to expand and verify the link.
• Ignore and Report: If the message is unexpected, don’t click—simply delete or report it.

?? Example 4: Fake Login Page

Phishing Website URL: https://amaz0n-customer-verification.com/login Page Appearance: Looks exactly like the Amazon login page, with logo, colors, and fields.

Red Flags:

• Slight URL Variation: “amaz0n” uses a zero instead of an “o” in Amazon.
• Unusual Domain Structure: Legitimate Amazon sites usually use amazon.com or a verified subdomain.

What to Do:

• Examine the URL Carefully: Look for misspellings, extra characters, or unusual domains.
• Verify on the Official Site: Open a new browser and navigate directly to amazon.com to log in safely.
