Phishing Links, their Common Characteristics & Identification

The Seeker 9:00 PM

 

What is a Phishing Link?

A phishing link is designed to look legitimate but redirects you to a malicious website intended to steal sensitive information, such as usernames, passwords, or credit card details.

Common Characteristics of Phishing Links

Phishing links often:

  • Mimic legitimate URLs: They may look like real websites but have subtle changes, such as extra characters or different domain endings (e.g., "example.com" vs. "examp1e.com").
  • Use shortened URLs: Attackers often use URL shorteners (e.g., bit.ly) to disguise the malicious link.
  • Contain urgent or alarming messages: For example, “Your account will be locked! Click here to verify.”

How to Identify Phishing Links

  1. Hover Over the Link:

    • Without clicking, hover your cursor over the link to see the actual URL.
    • Look for discrepancies, like misspelled domain names or suspicious subdomains.

  2. Inspect the Email/Message:

    • Check for spelling errors, generic greetings, or requests for sensitive information.
    • Legitimate companies rarely ask for personal information via email.

  3. Check the SSL Certificate:

    • Look for "https://" in the URL. However, a secure connection doesn't guarantee the site is legitimate—it just means the data is encrypted.

  4. Use Link Scanners:

    • Websites like VirusTotal or URLVoid allow you to paste a link and check if it's malicious.

      Protecting Yourself and Others

    • Educate yourself and others about phishing tactics.
    • Enable multi-factor authentication (MFA): This provides an extra layer of security.
    • Use security software to detect and
     
  5. Phishers use various techniques to hide the actual malicious link and make it appear legitimate to trick users. Here are the most common methods they employ, along with explanations:

    1. URL Shorteners

    Phishers use services like Bitly or TinyURL to create shortened links that mask the actual destination. For example:

  6. Original link: http://malicious-site.com/steal-data
  7. Shortened link: http://bit.ly/3aBcDeF

How to detect:

  • Use a URL expander service like CheckShortURL to reveal the actual link.

    . HTML Link Masking

    Phishers use HTML to display a legitimate-looking link while directing users to a malicious site. For example:


    3. Homograph Attacks (Unicode Characters)

    Phishers replace characters in the URL with similar-looking characters from other alphabets. For example:

  • Real: www.paypal.com
  • Fake: www.pаypal.com (the "а" is a Cyrillic character, not a Latin "a")

How to detect:

  • Copy the URL and paste it into a plain text editor to reveal the true characters.
  • Use tools like Punycode Decoder to detect non-ASCII characters.

4. Subdomain Spoofing

Phishers create subdomains to make the URL appear legitimate. For example:

  • Legitimate: https://www.bank.com/login
  • Phishing: https://www.bank.com.malicious-site.com/login

How to detect:

  • Focus on the main domain (just before the .com, .net, etc.). In the example above, the main domain is malicious-site.com.

5. Email Embedding or Hidden Links

In phishing emails, the text of a link might appear legitimate, but clicking it takes you elsewhere. For example:

  • The email says: Click here to reset your password!
  • Behind the scenes: <a href="http://malicious-site.com/reset-password">Click here</a>

How to detect:

  • Right-click the link in the email and select "Copy Link Address." Paste it into a text editor to examine the URL.

6. Image Links

Phishers may embed a clickable image instead of text. The link is hidden in the image's HTML code.

How to detect:

  • Right-click the image and select "Inspect Element" (in most browsers) to view the underlying HTML.

7. URL Obfuscation

Phishers can use long, confusing URLs filled with parameters and strings to obscure the true destination:

  • Example: http://legitimate-site.com.redirect-to.malicious-site.com/secure?session=12345

How to detect:

  • Look for unnecessary redirects and focus on the main domain.

Tips to Stay Safe

  • Always verify links before clicking, especially in unsolicited emails or messages.
  • Use link-scanning tools like VirusTotal.
  • Be cautious with links that demand immediate action or claim urgency.
  • Keep your software, browsers, and antivirus tools updated.

hishing attacks are continually evolving, with cybercriminals adopting advanced technologies to enhance their deception. Here are some of the latest phishing techniques to be aware of:

1. AI-Generated Phishing Scams

Cybercriminals are increasingly using artificial intelligence (AI) to craft highly personalized and convincing phishing emails. By analyzing information from social media and other online sources, AI enables attackers to create messages that closely mimic legitimate communications, making them harder to detect.

New York Post

How to Protect Yourself:

  • Verify the Sender: Always check the sender's email address for authenticity.
  • Be Skeptical of Urgent Requests: Be cautious of emails urging immediate action or requesting sensitive information.
  • Use Two-Factor Authentication (2FA): Enable 2FA to add an extra layer of security to your accounts.

2. Deepfake-Assisted Phishing

Advancements in AI have led to the creation of deepfake technology, allowing attackers to produce realistic audio and video impersonations. These deepfakes can be used to impersonate executives or colleagues, convincing victims to divulge confidential information or authorize financial transactions.

Financial Times

How to Protect Yourself:

  • Verify Through Multiple Channels: Confirm requests through a secondary communication method, such as a phone call or in-person verification.
  • Be Aware of Unusual Requests: Be cautious of unexpected or out-of-character requests, even if they appear to come from known individuals.

3. QR Code Phishing

The use of QR codes has become widespread, and cybercriminals are exploiting this by embedding malicious URLs within QR codes. When scanned, these codes can direct users to phishing sites designed to steal personal information.

How to Protect Yourself:

  • Avoid Scanning Unknown QR Codes: Only scan QR codes from trusted sources.
  • Use QR Scanner Apps with URL Preview: Utilize apps that allow you to preview the URL before opening it.

4. Phishing-as-a-Service (PhaaS)

The emergence of Phishing-as-a-Service platforms has lowered the barrier for conducting phishing attacks. These services provide ready-made phishing kits, enabling even unskilled attackers to launch sophisticated campaigns, including those capable of bypassing multi-factor authentication (MFA).
