We all have found ourselves clicking on a seemingly legitimate email. Maybe it was an email from a colleague, a bank, or a subscription service. Now think of when you clicked on that link and downloaded that file, only to realize later that it was a clone phishing attack. These attacks don’t just trick users; they mirror trusted messages to exploit familiarity and trust.
In this blog, we’ll explore the clone phishing meaning, how cloning attacks operate, and most importantly, what you can do to stop them in their tracks. Let’s decode this silent cyber threat together.
In simple words, clone phishing is a type of cyberattack involving someone trying to steal an official email you’ve likely received and then copy it virtually without making any changes. The data, style, and even the email address from which the message seems to come may easily be falsified. But the issue is: the messages you receive don’t include the actual documents; they have been changed with harmful code.
So when you click or download, you aren’t following a safe path. It may seem like you are going to safe sites, but some websites can prey on you and make you download malicious software without you noticing. So, think about this: if you start to get the same-looking message again after some time, but it comes from a cybercriminal pretending to be your friend, you have to be careful. That is the main idea behind a cloning attack.
In 2020, workers from a healthcare provider got what looked like a reminder for a previous meeting. The details on the email were similar to what was included in the invite, but the link didn’t match. One single click and the safety of the system was broken. Just a couple of hours after the infection, ransomware made my important files inaccessible to me. This was a typical cloning attack carried out following the proper steps.
You can protect yourself by studying how such attacks happen and learn how to identify email senders. Here’s a step-by-step breakdown:
The approach starts when the attacker watches or copies a real message from Dropbox or from your team leader.
They take over the format, style of writing, and subject line and hide their identity by using the same email address name. Malicious links are put in the place of the regular links and attachments.
The fake message comes from the email address that is addressed as if it were another copy of a previous genuine email from the same source.
Assuming it’s safe, the recipient clicks on the link or downloads the attachment, unleashing malware or being taken to a phishing page.
When access is achieved, attackers might search for sensitive information, add spyware or attack different parts of the network.
Clone phishing is dangerously effective for one reason: familiarity breeds trust.
It’s easy to confuse clone phishing with general phishing, but there are key differences:
Feature | Traditional Phishing | Clone Phishing |
Email content | Often generic or poorly written | Identical to a legitimate past message |
Sender | Random or fake | Spoofed or compromised |
Links/Attachments | Always malicious | Replaced in a legitimate-looking message |
Success rate | Moderate | High due to familiarity and trust |
Here are practical red flags to watch for:
If you receive an email that suddenly references an old message, especially with new links or attachments, pause.
Hover over links before clicking. If the destination URL doesn’t match the expected domain, that’s a warning sign.
Look out for slight changes in tone, missing personalization, or odd phrasing—even if the email looks like previous messages.
If the sender’s email address is slightly off (e.g., using a number “1” instead of the letter “l”), it’s likely spoofed.
Stopping clone phishing is not just about using software; it’s about creating a strong cybersecurity culture. Here are three ways by which you can protect yourself:
Train your experts regularly on the latest phishing tactics, especially cloning attacks. Use phishing simulations to teach employees how to identify suspicious emails and avoid clicking on unknown links.
Implement spam filters and email security gateways that scan for known threats, lookalike domains, and signs of email spoofing. Many tools also check for cloned content patterns.
Assume no email or communication is trustworthy by default. Utilize robust verification techniques, including the use of multi-factor authentication (MFA), and control access to confidential information depending on the user roles and behaviors.
The good news? You can fight back. Here’s how individuals and organizations can stay one step ahead:
With the use of SPF, DKIM, and DMARC, sender authentication is possible. Organizations need to use these protocols to fight email spoofing.
In cases where credentials are lost, the MFA can still ensure that there is no unauthorized access to the users’ accounts since it will still demand an extra step of verification.
Clone phishing preys on human error. Regular cybersecurity awareness training builds awareness and quick detection skills.
Patching software and browsers reduces vulnerabilities that attackers could exploit through malicious attachments.
Organizations can use email filters to detect and block domains that resemble internal or frequently used ones.
Security software with real-time threat detection can scan links and flag cloned messages.
Encourage team members to report suspicious emails and make security a shared responsibility, not just an IT issue.
Clone phishing is not just a personal threat but also a significant threat to businesses. In 2023, a multinational firm lost over $1.7 million when a clone phishing email from a fake vendor led to a criminal wire transfer.
Even with precautions, no system is bulletproof. Here’s how to respond to a suspected clone phishing attack:
You may also talk to the authorities by heading to the National Cyber Crime Reporting Portal at https://cybercrime.gov.in for more guidance.
Cybercriminals are getting smarter, and so can we. If you know how clone phishing attacks operate and use preventive safety measures, you can significantly decrease the risk.
Just remember that clone phishing has nothing to do with system breaches; it’s all about taking advantage of trust. Remember to verify before you click, and keep yourself and your team informed. Because Clone phishing may look familiar, but its impact is anything but. Learn it, spot it, and stop it.
Clone phishing is a kind of phishing process that makes a genuine email and alters its information with malicious links. On the contrary, spear phishing is specific to a particular individual using special messages. Both use deception, but clone phishing mimics prior trusted communications.
Antivirus software can detect malicious attachments and links, but it won’t necessarily prevent you from opening a phishing email. Human awareness and secure practices, like verifying the sender, are your best defense.
Don’t click anything. Rather, report the email to your IT department or email service provider. Or you could talk to the supposed sender through a separate channel (such as a phone call) to verify whether or not they’re even the ones who sent it.
