What is Spoofing? Learn How to Prevent It in Your Company!

Have you heard of spoofing? It is one of the many malicious practices in the digital world today and is one of the most commonly used by criminals.

Existing for a long time, spoofing operates stealthily and covertly, harming the victim without immediate detection.

With the proliferation of cybercriminals using the internet, this type of fraud is present in various mediums such as email, SMS, websites, links, messages, etc. They operate in this way because it causes the victim to suffer and, consequently, they cannot recover any information from the wrongdoing.

To better understand how it works and to prevent your company from falling victim to a spoofing scam, we'll cover everything you need to know about this technique known in cybersecurity.

What is Spoofing? Derived from the English verb “to spoof,” which means to forge or falsify, spoofing involves disguising a communication from an unknown source as coming from a known and trusted source.

If successful, these attacks can infect various systems and networks, compromising data and, in some cases, causing significant financial damage. Additionally, they can harm a company's public reputation.

Spoofing can also involve redirecting internet traffic to overload networks or lead clients to malicious sites to steal information or distribute malware.

It's worth noting that phishing attacks, which have become popular in recent years, are an evolution of spoofing.

Having understood the concept, let’s explore how spoofing works.

How Does Spoofing Occur? Spoofing can be applied through various communication channels and may involve different levels of expertise. It requires a certain level of social engineering.

For a spoofing attack to be successful, the methods need to be meticulously precise. Perpetrators use social engineering to exploit human vulnerabilities like greed, fear, and naivety.

Here’s an example: The scammer will always appeal to the victim's emotions. They might exploit fear to obtain information or money, such as scams involving family members, claiming that a relative is in financial trouble and needs money urgently.

Often, scammers target the elderly due to the preconceived notion that they have less tech knowledge.

Main Types of Spoofing Cybercriminals use various methods and techniques to achieve their goals, and spoofing is no different.

To avoid falling victim, here are the most common types:

• Email Spoofing: This involves emails that seem to come from trusted sources like clients, colleagues, or managers but are actually crafted by cybercriminals to gain your trust and execute their desired action. These emails may request money transfers or access to systems, and may also contain malicious attachments that install malware.
• DNS Spoofing: This manipulation of the Domain Name System (DNS) redirects traffic to malicious websites. Known as DNS cache poisoning, this method introduces corrupt DNS data into the user’s terminal, preventing access to legitimate sites and redirecting users to addresses set by criminals.
• Website Spoofing: This involves creating a website that imitates a known and trusted site to deceive users into believing they are on a legitimate site. Often, scammers use similar domain names to trick users into providing login and personal information.
• IP Spoofing: This technique involves hiding the sender’s location by making a computer think that the information is coming from a trusted source, allowing malicious content to pass through.

How to Identify Spoofing? As scams become known, scammers refine their techniques. Since spoofing aims to appear somewhat legitimate, identifying an attack can be challenging.

It's crucial to stay vigilant. If you receive a suspicious message from your bank, for example, contact your manager to verify its authenticity.

The idea is to always seek contact through another channel if you suspect a dubious message.

This way, you have the opportunity to identify a potential attack before it’s too late.

Protecting Yourself from Spoofing in 5 Steps Now that you understand what spoofing is, here are some measures to protect yourself:

1. Unsure about the email’s origin? Don’t open it. Most email programs allow you to view the message’s source code, which can help you see the content without executing any malicious elements.
2. Update your passwords regularly. If a cybercriminal obtains your login credentials, having a new password can minimize damage. Create strong passwords that are hard to guess and use a password manager for secure storage.
3. Be cautious. Be wary of messages asking for personal data, especially passwords. Companies usually do not request such information via email.
4. Use two-factor authentication. This adds an extra layer of security to your passwords. However, it’s not foolproof, so consider other precautions as well.
5. Use technology to your advantage. There are security tools that check emails for various security aspects. Utilize these tools and consider antivirus programs that perform such checks.
