The Internet has become a significant source of information and communication for both personal and professional purposes. As such, it has also become a target for cybercriminals who want to steal sensitive data from unsuspecting victims. One of the most common ways they do this is through email spoofing.
Email spoofing involves sending out fraudulent messages pretending to come from another person or organization. This type of fraud has become increasingly prevalent over the years due to the rise of social media platforms such as Facebook and Twitter.
Email spoofing is becoming more sophisticated, and scammers now create realistic-looking emails that look real enough to fool even the most tech-savvy users. The best way to protect yourself against these threats is by using a reliable anti-spam and antivirus solution.
The most common way that attackers use email spoofing is through phishing attacks. Phishing is when an attacker tricks you into giving up your personal information by impersonating a trustworthy company in order to get access to your sensitive data. For example, if you receive an email from eBay saying that there was a problem with your PayPal account and asks for your username/password, this could be a sign of a phishing scam.
Another popular method of email spoofing is called spear-phishing. Spear-phishing is when an attacker uses email spoofing to target individuals. An attacker will create a fake email address and pretend to be someone you know. Then he will send you a message asking for sensitive information like passwords or login credentials.
According to the latest statistics from McAfee Labs, more than half of all global spear-phishing campaigns are being conducted via email spoofing. In addition, over 60% of these attacks were successful.
Even though most emails are protected by encryption, sometimes they get sent without any encryption. If you’re an employee responsible for making important financial decisions or if you use personal emails at work, here are some things you can do to protect yourself from phishing scams.
You can implement several technical precautions to prevent spam bots from gaining access to your system. For example, sending out emails through a subdomain (e.g., @help.organization.com) may be more challenging for spammers to access your system.
A Sender Policy Framework helps block unwanted emails from reaching people’s inboxes. Two Mailbox Exchange records let your email server direct the messages into appropriate folders. These settings enable your email server to route messages sent from a third-party server to your own email address. Once configured, the mail server routes these messages to your own email account.
Anti-malware programs can help prevent phishing scams by identifying and stopping malicious websites before they reach your computer. Even if an email isn’t blocked at its source, anti-malware programs can block it from ever reaching your computer.
An Email Signing Certificate allows you to send an encrypted email that only the intended recipient will be able to read. It also lets people verify that the email came from you rather than someone else.
Asymmetric encryption uses two keys: one for sending messages (the public key) and another for decrypting them (the private key).
The receiver has a private key for encrypting messages so they can be decrypted by anyone who knows the corresponding public key.
You can determine whether the IP address is valid with a reverse DNS lookup. You can find out who owns the IP address, allowing you to see if the person behind the IP address is sending emails. An online reverse DNS lookup service lets you do this quickly and easily.
Domain-base Messaging Authentication, Reporting & Conformance (DMARC) allows emails to be authenticated by their domain name. It also lets recipients know whether they receive messages from a legitimate sender.
A part of the DMARC process includes the sender policy framework (SPF), which authenticates messages by checking if they come from an authorized source. If the email passes both SPF and SPF alignment tests, it will give the DMARC test and be accepted.
Spoofed emails can be forged using different methods of varying complexity. These vary depending on which parts of an email they’re trying to forge.
There are different variations you might encounter when browsing the internet.
Display name spoofing occurs when someone registers a new Gmail account with your contact’s display name. When they send emails to you, the from field will show the fake email address instead of yours. You may also receive emails from people who haven’t sent them any messages.
This kind of email will also bypass any anti-spam filters. It won’t get filtered out as spam because it’s a legitimate email address. Display name spoofing is very easy to do, so often, these emails are marked as spam. Most modern email clients don’t show metadata. So, display name spoofing works quite well. Because of the prevalence of smartphones, most email clients only allow for a display name. So, display name impersonation is quite common.
Suppose the attacker is trying to make his attack look legitimate. He might try to trick users into thinking that the message came from someone they know. For example, if the attacker wants to impersonate an employee of your company, he could pretend to be a customer support specialist.
This attack does not require access to the target’s internal network, nor does it need to compromise the target’s email accounts. Instead, it relies on compromised mail servers that do not require authentication and allow manual specification of the to and from addresses.
Suppose a domain is secured, and domain spoofing is impossible. In that case, attackers will most likely set up a lookalike domain, e.g., “@d0main” instead of “@domain”. This change could be minimal so that no one notices it. It works because when did you ever bother to check the headers of an email?
Using a very similar hostname, which also bypasses anti-spam filters due to being a valid mail server, the attacker creates a false sense of security. It might be just sufficient to persuade its victim to reveal their username, transfer money, or upload some files. In all these cases, email metadata investigation remains the only way to verify whether the message is genuine or not. However, it‘s often impossible to do on the go, especially with smaller smartphone displays.
The reasons for email spoofing are quite straightforward. Usually, the criminal has something malicious in mind, like stealing a company’s private data. Here are the most common reasons behind this malicious activity
The reasons for email phishing are quite straightforward. Usually, the criminal has something malicious (like stealing your private information) in mind, so they’ll try to trick you into giving them access to your account.
Here are the most popular reasons why people fall victim to these scams:
Hiding Identity: It’s one of the main benefits of email spoofing for attackers to stay anonymous.
Avoiding a Spam Blacklist: Many email service providers allow users to create a spam filtering blacklist. Adding a spamming user’s name or email address to a filter is a way to prevent them. When spoofing emails, spammers may use addresses that are unlikely to be on the blacklist. As a result, these messages pass through the filters without being detected.
Tarnishing the Image of the Assumed Sender: A spoofed email message may contain malicious links, incorrect information, outright lies, and/or subtle untruths intended to make the sender look bad. Spoofing emails can also be used to make an organization or individual appear insecure or compromised by viruses or hackers. These messages can damage the reputation of the purported sender, harming their business or social prospects, and they may cause organizations to lose money or suffer reputational harm.
Intending to do Personal Damage: Sometimes, the intent might be malicious. When an email is spoofing, the actual senders may gain access to the targets’ computers, businesses, social media profiles, and more. This could cause the target to look bad, harm their reputation, or damage the target’s devices. To avoid these problems, email spoofing should not be used to introduce any type of malware. Malicious emails often contain links to sites where users can download ransomware, so if your email contains such a link, you should delete it immediately.
Cybercriminals often use spoofing as a part of a phishing scam. A phishing scam is a type of social engineering fraud where someone tries to trick another person into giving out personal information (such as passwords) or clicking on malicious links. Spoofing is one technique cyber criminals use to imitate legitimate emails. They may also send fake messages through instant messaging systems. For example, they might pretend to be your boss, asking you to do something illegal. Or they might pretend to be friends who want to meet up with you. In either case, if you respond, they can access your computer and steal any sensitive information.
Spoofing is often associated with domain impersonation, where an email address similar to another email address (such as amazon.com) is used. A spoofed message might claim to be sent from a customer service department but comes from someone else entirely.
In conclusion, the most common way attackers can get your personal information is through phishing attacks. Phishing is when you receive an email asking for sensitive information like passwords, usernames, and other private data. If you click on any suspicious links in emails, you could end up giving away all kinds of valuable information.
