What is Spoofing? | Spoofing Definition

In terms of cybersecurity, spoofing refers to when someone or something impersonates another entity in an effort to win our trust, get access to our systems, steal data, steal money, or distribute malware. Spoofing attacks can take many different forms, such as:

  • Email spoofing
  • Website and/or URL spoofing
  • Caller ID spoofing
  • Text message spoofing
  • GPS spoofing
  • Man-in-the-middle attacks
  • Extension spoofing
  • IP spoofing
  • Facial spoofing

So, how do cybercriminals deceive us? Often, simply mentioning the name of a large, well-known institution is enough to compel us to divulge information or take action. A counterfeit email from PayPal or Amazon, for example, may query about purchases you never made. If you are concerned about your account, you may be tempted to click the included link.

Scammers will direct you to a web page with a virus download or a bogus login page—complete with a familiar logo and spoofed URL—in order to steal your username and password.

There are several other ways a spoofing attack may proceed. In all of them, scammers rely on victims falling for the false. You could fall prey to a spoofing attack at some time if you never question the reliability of a website or wonder if an email is a forgery.

To that purpose, spoofing is the sole topic of this page. You’ll learn about the many kinds of spoofs, how they operate, how to tell real emails and websites from phoney ones, and how to avoid being a target for scammers.

What are the types of Spoofing? | Types of Spoofing Attacks

Email spoofing

Email spoofing is the practise of sending emails with bogus sender addresses, typically as part of a phishing effort to steal your information, infect your machine with malware, or just beg for money. Malicious email payloads commonly include ransomware, adware, cryptojackers, Trojans (such as Emotet), or malware that enslaves your machine in a botnet (see DDoS).

Yet, a faked email address is not always sufficient to mislead the typical individual. Consider receiving a phishing email with what seems to be a Facebook address in the sender box, but the content of the email is written in plain text with no design or HTML—not even a logo. That’s not something we’re used to hearing from Facebook, and it should set off some alarm bells.

As a result, phishing emails frequently have a variety of misleading elements:

Fake sender address that is intended to appear as though it is from a person you know and trust, such as a friend, coworker, family member, or business partner.
In the case of a firm or organisation, the email may incorporate known branding; e.g. logo, colours, typeface, call to action button, etc.

  • Spear phishing attacks use customised language and use the recipient’s name to target a specific person or small group within a corporation.
  • Several typos are present. Despite their best efforts, email fraudsters sometimes don’t take the time to check their own work.
  • Email spoofs frequently contain mistakes or appear to have been translated using Google Translate. Be cautious of strange sentence structures;
  • Be wary of unusual sentence constructions; companies like Facebook or PayPal are unlikely to make such errors in their emails to customers.

Sextortion schemes rely heavily on email spoofing. These frauds deceive us into believing that our webcams have been infiltrated with spyware and are being used to record us watching porn. These counterfeit emails would state things like “I’ve been watching you watch porn,” which is a really strange thing to say. In this case, who is the true creep? The fraudsters then demand Bitcoin or another cryptocurrency in exchange for sending the video to all of your contacts. To provide the idea of validity, the emails may contain an old password from a prior data breach. The spoofing occurs when the scammers alter the email sender field to seem to be sent from your allegedly compromised email account. You may rest confident that no one is observing you.

Website spoofing

The goal of website spoofing is to make a harmful website appear to be authentic. The faked site will seem just like the login page for a website you visit, right down to the branding, user interface, and even a spoofed domain name that appears identical at first sight. Cybercriminals use faked websites to steal your username and password (known as login spoofing) or to install malware on your machine (known as a drive-by download). A faked website is usually used in connection with an email spoof, in which the email contains a link to the spoofed website.

Noting that a faked website differs from a hacked website is also important. When a website is hacked, there is no spoofing or fakery involved; rather, hackers have infiltrated and taken control of the genuine website. Malvertising is also a distinct type of malware. Cybercriminals in this instance have used reputable advertising networks to run harmful adverts on reputable websites. These advertisements infiltrate the victim’s machine with malware.

Caller ID spoofing

Scammers use caller ID spoofing to trick your caller ID into thinking the call is coming from somewhere it isn’t. Scammers have discovered that if the caller ID indicates an area code similar to or close to your own, you are more likely to answer the phone. Scammers will often fake the initial few digits of your phone number as well as the area code to give the appearance that the call is coming from your neighbourhood (aka neighbour spoofing).

Text message spoofing

Sending a text message using another person’s phone number or sender ID is known as text message spoofing or SMS spoofing. If you’ve ever sent a text message using your laptop instead of your phone, you’ve faked your own phone number in order to send the message. Businesses routinely spoof their own numbers for convenience and marketing reasons by swapping out the lengthy number with an alphanumeric sender ID that is simple to remember. Fraudsters use an alphanumeric sender ID to conceal their actual identities, frequently posing as a reputable business or institution. Links to virus downloads or SMS phishing sites are frequently included in the fake texts.

Scammers might take advantage of the employment market by impersonating as staffing companies and giving victims too-good-to-be-true job offers through text messaging. In one case, an Amazon work-from-home position included a “brand new Toyota Corrola.” First and foremost, why do you need a corporate car if you work from home? Second, is a Toyota “Corrola” only a rebadged Toyota Corolla? Scammers, good try.

GPS spoofing

When you use GPS spoofing, you deceive your device’s GPS into believing you’re in one area while you’re actually in another. Why would somebody want to fake their GPS? Pokémon GO is a two-word phrase. Pokémon GO cheats may make the popular mobile game think they’re near an in-game gym and take over that gym by using GPS spoofing (winning in-game currency). The cheats, in reality, are in an entirely other location—or nation. Similarly, YouTube videos show Pokémon GO gamers catching numerous Pokémon without ever leaving their house. While GPS spoofing may appear to be child’s play, it’s easy to envisage threat actors using the tactic for more sinister purposes than obtaining mobile game gold.

Man-in-the-Middle (MitM) attack

When you use free Wi-Fi at your local coffee shop, you may be vulnerable to Man-in-the-Middle (MitM) attacks. Have you considered what may happen if a cybercriminal compromised the Wi-Fi or set up another bogus Wi-Fi network in the same location? In any instance, you have the ideal conditions for a man-in-the-middle attack, so termed because hackers may intercept online communication between two parties. Spoofing occurs when thieves modify the communication between the parties in order to redirect payments or get sensitive personal information such as credit card details or logins.

As an aside, while most MitM attacks intercept data in the Wi-Fi network, another type of MitM attack intercepts data in the browser. This is referred to as a man in the browser (MitB) attack.

Extension spoofing

When fraudsters need to mask executable malware files, they use extension spoofing. Criminals frequently employ the extension spoofing tactic of naming the file something like “filename.txt.exe.” Because criminals are aware that file extensions are concealed by default in Windows, this executable file will appear to the ordinary Windows user as “filename.txt.”

IP spoofing

When someone wishes to hide or mask the location from which they transmit or request data online, they utilise IP spoofing. IP address spoofing is used in distributed denial of service (DDoS) attacks to prevent malicious traffic from being filtered out and to conceal the attacker’s location.

Facial spoofing

With its ramifications for both the development of technology and our daily lives, facial spoofing may be the most intimate. The current state of face ID technology is somewhat constrained. We mostly use our looks to unlock laptops and mobile devices. Yet sooner or later, we could start signing documents and paying payments with our faces. Consider the effects once you are able to open a credit line using only your face. Really spooky. Researchers have shown that it is already possible to get into a device protected by face ID by using 3D facial models created from your social network photographs. Malwarebytes Labs reported on deepfake technology being used to produce fake news videos and fake articles, taking things a step further.

How does Spoofing work? | How are Spoofing Attacks carried out?

We’ve discussed the many types of spoofing and skimmed over their technical details. But there’s a bit more to discuss in the case of email spoofing. Cybercriminals can conceal their genuine identities in an email fake in a few different ways. The most secure choice is to break into an unprotected mail server. Technically speaking, the email in this instance appears to be coming from the claimed sender.

The simple method is to enter any address in the “From” column. The only issue is that the reply will be delivered to the person named in the “From” column, not the attacker, if the victim responds or the email cannot be sent for any reason. Spammers frequently employ this method to utilise authentic emails to avoid spam filters. Other than your email account being hacked, this is one reason you could have gotten answers to emails you’ve never sent. Backscatter or collateral spam is what is meant by this.

In what is known as a homograph attack or visual spoofing, attackers frequently spoof emails by registering a domain name that is identical to the one they’re trying to impersonate. Take “rna1warebytes.com,” for instance. Keep in mind that the letter “l” has been replaced with the number “1”. Keep in mind that the letters “r” and “n” were utilised to mimic the letter “m.” Also, this provides the attacker with a domain to employ in the creation of a faked website.

Whatever the spoof, simply sending a phoney website or email to everyone and hoping for the best isn’t always sufficient. A mix of the spoof itself and social engineering is necessary for successful spoofing. Cybercriminals may utilise social engineering techniques to deceive us into divulging personal information, clicking a harmful link, or opening an attachment that contains malware. The social engineering playbook contains a variety of strategies. Cybercriminals rely on human weaknesses like fear, naivete, greed, and vanity to manipulate us into acting in ways that aren’t in our best interests. For example, if you were the victim of a sextortion fraud, you may give the con artist bitcoin out of concern about the public exposure of your figurative dirty laundry.

Human weakness isn’t necessarily a terrible thing either. Although curiosity and empathy are typically positive traits, thieves like preying on those who possess them. The stranded grandkids scam is one example, where a loved one is purportedly in jail or the hospital in a faraway nation and urgently requires money. A text message or email may say, “Grandpa Joe, I was detained for drug smuggling in [insert country name]. Please send the money, and please don’t tell my parents. [Three smiley faces winking] You’re the greatest!” Here, the con artists rely on the grandparent’s typical ignorance of his grandson’s whereabouts at all times.

A mix of the spoof itself and social engineering is necessary for successful spoofing. Social engineering is the techniques used by hackers to deceive us into disclosing personal information, clicking a dangerous link, or opening a file that contains malware.

How can Spoofing be detected? | Spoofing Attack Detection

These are some indicators that you are being faked. If you see these signs, hit erase, choose Back, exit the browser, and do not press Go.

Website Spoofing

  • No green bar or lock icon. An SSL certificate, which signifies that a third-party certification body has confirmed that the web address genuinely belongs to the entity being checked, is required for all safe, reliable websites.
  • Remember that SSL certificates are now available for free and are simple to get. Even though a site may have a padlock, it doesn’t always imply it’s authentic.
  • Please keep in mind that nothing online is really secure.
  • File encryption is not used on the website. Hypertext Transfer Protocol, or HTTP, is as ancient as the Internet and refers to the guidelines followed while distributing data online.
  • Reputable websites will nearly always utilise HTTPS, the encrypted form of HTTP, when sending data back and forth. If you’re on a login page and the address bar of your browser shows “http” rather than “https,” you should be wary.
  • Make use of a password manager. Each trustworthy website you keep in your password vault will automatically fill in your login information when you use a password manager like 1Password. You will know you’re being spoofed if your password manager does not detect a spoofed website and does not automatically fill in the login and password boxes.

Email spoofing

  • Verify the sender’s address once more. As previously indicated, con artists will register phoney domains that closely resemble real ones.
  • Google the contents of the email. You might be able to tell if a known phishing email is spreading around the internet by performing a fast search.
  • Links that are embedded have odd URLs. Before clicking, hover your cursor over Websites to verify them.
    mistakes in grammar, strange syntax, etc. Fraudsters frequently fail to check their writing.
  • The email’s content is too wonderful to be true.
  • Attachments are present. Attachments should be avoided, especially if they come from an unidentified sender.

Caller ID spoofing

  • Caller ID may be readily faked. Our landlines have turned into a hub for scam calls, which is a terrible state of affairs. When you consider that the majority of individuals who still use landlines are elderly—the demographic most vulnerable to scam calls—this is very concerning.
  • Let incoming calls from unauthorised callers to go to voicemail or the answering machine on your landline.

How can I protect against Spoofing? | Safeguard Against Spoofing Attacks

  • You should first understand how to recognise a spoofing attack.
  • Activate the spam filter.
  • By doing this, the vast majority of fake emails won’t even reach your mailbox.

When opening links or attachments in emails from unknown senders, use caution. If there’s a chance the email is genuine, get in touch with the sender via another channel and ask them to validate the email’s contents.

Open a new tab or window to log in. Don’t click the offered link if you receive a dubious email or text message asking you to log into your account and perform some sort of action, like verifying your details. Open a different tab or window and go directly to the website. You may also use the specific app on your phone or tablet to log in.

Answer the phone. Never be hesitant to phone or text the sender of a strange email that appears to have come from someone you know to verify that they did, in fact, send it. This suggestion is particularly valid if the sender makes an unusual request, such as, “Please purchase 100 iTunes gift cards and email the card numbers to me, thanks. You’re welcome, boss.”

Windows should display file extensions. By selecting the “View” tab in File Explorer and ticking the box to reveal file extensions, you may override Windows’ default configuration that hides file extensions.

Even if this won’t stop fraudsters from faking file extensions, at least you’ll be able to detect them and keep those harmful files from being opened.

Get a reliable antivirus application. Don’t panic if you accidentally click on a malicious link or file; a decent antivirus application will be able to warn you of the risk, block the download, and stop malware from infecting your device or network. For instance, Malwarebytes offers antivirus and anti-malware programmes that you may test out before subscribing to.
