Understanding Clone Phishing
Traditional phishing vs Clone Phishing
Traditional phishing is a type of cyber attack that involves tricking people into disclosing sensitive information such as login credentials, credit card numbers, or personal information, by sending them fake emails, messages, or websites that impersonate a legitimate entity, such as a bank, a social media platform, or a government agency.
In Clone Phishing, Attackers create convincing copies of real emails, such as invoices, payment requests, or security alerts, and modify them to include malicious links or attachments that can infect computers with malware or direct victims to fake login pages. Hackers often do this by intercepting the message before it reaches to the victim.
How it works?
Cybercriminals create a clone of a legitimate email, often using a spoofed email address that closely resembles the real sender’s. They then replace the original links or attachments with malicious ones and send the cloned email to the target.
- Attackers choose a popular brand to impersonate and create email which is identical to that of original company along with a fake-website using brand characteristics, these can be typo-squatted domains which users do not observe in most cases. which is crafted to gain victim’s trust.
- The clone email is sent large number of individuals, these mails might contain malicious intent or malicious links and the communication will resemble original communication of the brand
- When a victim falls prey to such attack he/she is either redirected to download malware or to a malicious site.
- Attackers harvests victims personal information or credentials using such method.
Clone phishing examples – An urgent email from customer support of any famous companies such as Flipkart, Amazon or others. Clone phishing uses sense of emergency by sending mail which requires immediate attention such as account expiry, Fake virus alert etc.
The role of social engineering
It relies heavily on social engineering to manipulate users into falling for the scam. By using familiar email formats and content, attackers gain the trust of their targets, making it more likely they’ll click on the malicious links or open the infected attachments.
Social engineering tactics are employed to deceive the target into providing their login details by clicking on a link. Some of these techniques involve inducing a sense of urgency, such as threatening to suspend the victim’s account if they do not log in promptly, or enticing them with a reward or benefit for logging in.
In addition, the attacker might use psychological strategies, such as making the victim feel familiar by mentioning their name or personal information in the email or message. Furthermore, incorporating a reputable brand or logo into the email or message can also raise the probability of the victim clicking on the link and giving away their login credentials.
The use of cloned email templates
To make their emails look more authentic, cybercriminals often use templates that closely resemble the ones used by legitimate companies or individuals. This increases the chances that their targets will fall for the scam.
By sending out numerous emails that appear to originate from a trusted entity such as a bank or social media website, attackers can leverage cloned email templates to conduct large-scale phishing campaigns. This approach can enhance the chances of deceiving unsuspecting recipients into disclosing sensitive data or engaging in actions that jeopardize their security.
The targeting of high-profile individuals and businesses
These attacks are often targeted to high-profile individuals and businesses, as they are more likely to have valuable information or assets that cybercriminals can exploit. These targets may also be more susceptible to social engineering due to the increased interest in their affairs.
