What is a cloning attack? How cybercriminals can replicate your online identity.


Updated on:

I’ve seen countless ways that cybercriminals try to steal your information and manipulate your online identity. One of the most insidious methods they use is known as a “cloning attack”. This is when an attacker creates an almost identical copy of your online identity, from the way you write to the friends you have on social media, all in an attempt to deceive and ultimately steal from you.

Imagine someone out there behaving as you, using your voice on the internet, writing your emails, creating social media profiles that look just like yours. You would think that this sort of thing is impossible, right? Unfortunately, it’s all too common in the world of cybercrime. Even with the increasing adoption of security measures, cloning attacks continue to be a persistent problem. So, what exactly is a cloning attack, and how can you protect yourself? Let’s find out.

What is a cloning attack?

Clone phishing is a type of cyber-attack where criminals create a fake replica of a legitimate email to trick their victims into thinking that the fraudulent email is indeed authentic. The attackers use advanced techniques to clone legitimate emails that greatly resembles actual emails. Many times, these cloned emails contain malicious links or attachments that can compromise the security of the recipient’s device.

    What is Clone Phishing?

    Clone phishing, also known as cloning, is a sophisticated form of social engineering attack where cybercriminals impersonate genuine emails. In this attack, the attackers create a duplicate of a legitimate email and send it to the targeted user. The email may contain malicious links or attachments that, when clicked or downloaded, can compromise the user’s computer or network.

    The cloned email looks almost identical to the original email, including the sender’s email address, subject line, and content. The only difference is the inclusion of a malicious link or attachment, often disguised as something genuine like an invoice or an urgent message. Unlike traditional phishing techniques, where the attacker sends mass emails to random users, clone phishing targets specific individuals.

    The Mechanism of Clone Phishing Attacks

    Clone phishing attacks typically involve the following steps:

    Step 1: Reconnaissance
    Attackers collect information on the target user, including their email address, job title, social media profiles, and any other publicly available information that can be used to personalize the attack.

    Step 2: Clone the Legitimate Email
    The attackers create a duplicate of the legitimate email, including the sender’s name, email address, signature, and other details that will trick the recipient into believing it’s genuine. They may also copy logos and other graphics from the company’s website to make the email look more authentic.

    Step 3: Inject Malware into the Clone
    The attackers add malicious links or attachments to the cloned email, often disguised as something important or urgent. The links can redirect the user to a fake website that mimics the legitimate one, asking them to enter their login credentials. Alternatively, the attachments can be infected with malware that can compromise the user’s computer or network.

    Step 4: Send the Email
    The attackers send the cloned email to the target user, hoping that they will fall for the trick and click on the malicious link or attachment.

    How Are Clone Phishing Attacks Different From Regular Phishing Attacks?

    Clone phishing attacks are more advanced than regular phishing attacks because they involve creating a convincing clone of a genuine email, rather than a generic mass email. The attackers invest time and effort into researching the target individual and their organization to create a personalized, convincing phishing email. This makes it more challenging for users to identify clone phishing as fraudulent.

    The cloned email is identical to the original except for the presence of a malicious link or attachment, whereas traditional phishing emails may have spelling errors, wrong email addresses, or poor grammar. Clone phishing attacks are also more targeted, focusing on specific individuals, while regular phishing attacks cast a wider net by sending mass emails to random users.

    Why Are Clone Phishing Attacks So Effective?

    Clone phishing attacks have a high success rate because they rely on social engineering and often exploit human error. The cloned emails appear legitimate, and the attackers use specific details relevant to the target, such as their job title, to make the email more convincing. The attackers may also use fear, urgency, and curiosity tactics to encourage the user to click on the malicious link or attachment.

    The cloned emails are often sent to people in positions of authority, such as CEOs or senior managers, who have access to sensitive information and can authorize transactions. Attackers see these individuals as prime targets because they are likely to have less cybersecurity knowledge and may be under pressure to act fast.

    Examples of Clone Phishing in Action

    Clone phishing attacks are prevalent and have affected many organizations worldwide. Here are some real-life examples:

    Example 1: In 2016, a clone phishing attack on payroll processor ADP affected around 640,000 employees and potentially resulted in tax fraud.

    Example 2: In 2017, hackers impersonated Netflix in a clone phishing attack, aiming to steal sensitive information from users.

    Example 3: In 2018, Google Docs users were targeted in a clone phishing attack that sought to obtain users’ Google login credentials.

    How to Protect Yourself Against Clone Phishing Attacks

    Here are some measures you can take to protect yourself from clone phishing attacks:

    1. Be vigilant. Be wary of unsolicited emails that ask for sensitive information or contain attachments or links, even if they appear to be authentic.

    2. Double-check the email. Compare the email address and the contents of the email to previous ones from the same sender. Check for spelling mistakes, grammar errors, and other inconsistencies.

    3. Do not click on suspicious links. Hover over any links in the email to see the destination URL. If it looks suspicious, don’t click on it. Instead, type the URL into your browser and go to the website directly.

    4. Use antivirus software. Install and regularly update antivirus software to detect and prevent malware.

    5. Keep your software updated. Ensure that your operating system, browser, and other software are up to date with the latest security patches.

    What to Do If You Fall Victim to a Clone Phishing Attack

    If you suspect that you have fallen victim to a clone phishing attack, take the following actions:

    1. Disconnect your device(s) from the internet. Disconnect from the internet to prevent further data loss or malware infection.

    2. Change your passwords. Change your passwords immediately and ensure that they are strong and unique.

    3. Alert your IT team. Contact your IT department or cybersecurity team and report the attack. They can assist you in cleaning up the intrusion.

    4. Monitor your accounts. Keep a close eye on your financial accounts and other online accounts for any suspicious activity.

    Clone phishing attacks are a serious threat, and individuals and organizations must remain vigilant and take necessary precautions to protect themselves. Stay informed, be cautious, and learn to recognize the signs of clone phishing to keep your sensitive data and computer systems secure.
