In an increasingly complex digital era, cyber threats continue to evolve, including increasingly sophisticated sender spoofing techniques.

Many internet users, including crypto traders, fall victim due to a lack of understanding of email spoofing, SMS spoofing, and various other forms of digital identity disguise.

This article will thoroughly examine what sender spoofing is, how it works, the risks involved, and steps to protect yourself from this manipulation technique.

What is Sender Spoofing?

Sender spoofing is a digital manipulation technique in which the sender’s address in a communication such as an email, SMS, or phone call is faked to appear to come from a trusted source.

This technique is often used for various purposes, such as phishing, data theft, financial fraud, and account sabotage. Although the terms spoofing and phishing sound similar, they have fundamental differences.

Phishing is a social engineering method that aims to steal sensitive information, such as credit card numbers or passwords, by posing as a legitimate service.

Typically, perpetrators create fake websites or applications that resemble genuine services and trick victims into entering their personal information.

On the other hand, spoofing often involves the use of malware or DDoS attacks to strengthen their actions.

However, both phishing and spoofing perpetrators try to gain the victim’s trust by stating personal information such as their date of birth, phone number, parents’ names, or bank account details.

Therefore, it is important to understand the types of spoofing in order to recognize and avoid them. Here are the types of spoofing and how to prevent them that you need to know.

1. SMS Spoofing

SMS spoofing allows perpetrators to change the sender’s number to appear as an official number from a particular company or institution. This technique is often used to send fraudulent messages or spread links containing malware.

2. Caller ID Spoofing

Caller ID spoofing allows perpetrators to change the phone number that appears when making a call, often using unusual numbers such as “+5555” or other short numbers.

With this technique, perpetrators can pretend to be official institutions to deceive victims.

3. Email Spoofing

Email spoofing is a technique in which perpetrators fake the sender’s email address to appear as if it comes from a trusted source.

The goals vary, from stealing personal data, spreading malware, to tricking victims into transferring money.

Email spoofing is rampant because email protocols such as SMTP do not have a built-in authentication system. In addition, the many fake sender generator services on the internet make it easier for perpetrators to carry out their actions.

How Does Sender Spoofing Work?

Spoofing senders exploit weaknesses in communication protocols that lack strong encryption or authentication, such as Simple Mail Transfer Protocol (SMTP) in email.

With this technique, perpetrators can insert fake information in the message header so that the recipient sees a sender address that looks legitimate, when in fact it comes from an untrusted source.

In the case of email spoofing, perpetrators can create emails that look like they come from a bank, crypto exchange, or other official institution.

This technique is done by editing the email header, especially the “From” section, so that the sender’s name looks convincing. Typically, the contents of this type of email will contain:

• A phishing link that directs the victim to a fake site to steal personal data.
• Malicious attachments containing malware or ransomware.
• Requests for sensitive information, such as account numbers or OTP codes, under the pretext of an emergency.

Case example:

For example, someone receives an email that looks like it comes from a crypto exchange, asking users to update their account information via a specific link.

In fact, the email was sent from a third-party server and not from the official domain of the official crypto exchange. If the victim follows the instructions and enters their account data, the perpetrator can immediately access and misuse it.

The Impact of Sender Spoofing on Digital Security

Sender spoofing attacks can carry various risks for individuals, companies, and the digital ecosystem as a whole.

This technique is often used to deceive victims by posing as a trusted party, which can ultimately lead to financial losses and data leaks.

1. Risks for Individuals

For internet users, especially those who are less vigilant, sender spoofing can result in:

• Loss of funds due to fraud requesting money transfers or theft of digital assets.
• Identity theft, where personal information such as phone numbers, email addresses, and account data is stolen for misuse.
• Account takeover, for example social media accounts, financial services, or emails are hacked after victims unknowingly provide their login credentials.

2. Risks for Companies

Companies can also suffer major losses due to sender spoofing, especially if their names are misused in fraudulent schemes. Some of the impacts include the following:

• Loss of brand reputation, because deceived customers can lose trust in the company whose name is used by criminals.
• Potential internal data leaks, especially if employees are fooled by spoofing emails disguised as official messages from superiors or business partners.

3. Impact on the Crypto World

In the crypto industry, sender spoofing is often used to deceive investors and traders through various methods, such as:

• Fake emails or messages impersonating an exchange platform, asking users to enter account credentials or transfer assets.
• Fake airdrops, where the perpetrators claim to provide free tokens but ask victims to send a certain amount of crypto as a “transaction fee” before getting a reward.
• Fake bounty campaigns, which promise rewards for users who complete certain tasks, but are ultimately used only to collect personal information or carry out scams.

How to Prevent and Deal with Sender Spoofing

Dealing with sender spoofing requires vigilance and proper precautions for both individuals and businesses. Here are some steps you can take to reduce your risk of becoming a victim of this attack.

1. For Users

• Do not easily believe emails or SMS that look suspicious, even if they use the name of an official company or institution.
• Check the sender’s domain, especially if the message asks for sensitive information or contains a link. Make sure the email address really comes from an official domain, not a fake one.
• Do not click on random links, especially those that are suspicious or come from unknown sources. Spoofed links often direct users to fake sites created to steal data.
• Enable two-factor authentication (2FA) on digital accounts, including crypto accounts, to add a layer of security if login credentials are stolen.

2. For Companies

Use email authentication protocols such as Sender Policy Framework (SPF), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) to prevent spoofed emails that impersonate the company.
Educate users and employees about the dangers of spoofing and how to detect it. Simulated phishing attacks can help raise awareness of this risk.
Use a trusted email service and anti-spoofing filter to filter suspicious incoming emails and prevent the spread of attacks through internal company communications.
