What is Spoofing In Cybersecurity? Types & Examples

Learn how spoofing negatively impacts organizations and what you can do to protect from these attacks. We also discuss the different types of spoofing attacks and how to take protective actions.

Spoofing is one of the most common tactics used by cybercriminals, which includes brand impersonation and forged credentials aimed at obtaining user’s information. A recent study shows that 61% of phishing attacks employed fake Microsoft login pages to capture enterprise credentials. It is crucial for organizations to understand what is spoofing in order to ensure that its vital information is safe and users’ confidence is maintained. To prevent unauthorized access, monetary loss, and reputational damage, it is essential to identify potential entry points and develop proper policies.

In this guide, we define spoofing in cyber security and identify its roots, categories, and implications. Furthermore, we will discuss the history of spoofing, the most common weaknesses, and the differences between spoofing and other types of attacks, such as phishing. You will also receive recommendations on spoofing detection and spoofing prevention strategies, including examples of how criminals implement these scams. Last but not least, we will demonstrate how SentinelOne’s sophisticated solution can protect users and infrastructure from stealthy attacks.

What Is Spoofing?

Spoofing definition involves a deliberate act where an attacker pretends to be another user, device, or service with the aim of gaining unauthorized access or acquiring sensitive information. Some of the illusions used by attackers include fake email headers, fake websites, and fake IP packets, which are used to make the target trust the attacker. To put it simply, “What is spoofing attack?” can be best explained as the act of impersonation where the offenders change identifiers to cover their real identity.

While some people may have a general idea of spoofing meaning as a type of identity theft, experts define spoofing as a specific type of attack that involves gaining unauthorized access to the targeted information. Given the nature of today’s networks and applications, spoofing attacks can occur through email phishing, DNS spoofing, or ARP spoofing, which is why it is essential to identify anomalous activity before it brings an organization’s security to its knees.

The main goal of spooning is to con users into giving away or leaking their sensitive credentials.

History of Spoofing

While the contemporary techniques of infiltration may involve the use of technical tools, spoofing in cyber security has its origin in social engineering. As time passed, new and more sophisticated protocols appeared that allowed the attacker to forge the IP addresses, Caller ID, or SSL certificates. In the following section, we provide a timeline of the major events in the history of spoofing to show how this type of activity has progressed from simple phone call pranking to computer hacking.

1. Early IP & Email Masquerades: During the early 1990s, the usage of the internet was already rising, but the security measures were not as developed. Some of the basic tools used in crafting IP packets help the attacker test spoofing on simple networks by faking source addresses to evade security measures put in place. It was also during this time that email became a tool for social engineering, even though spam filters were not yet well developed. Such initial advances paved the way for more complex espionage tactics, changing the definition of spoofing in the subsequent years.
2. Emergence of Caller ID & ARP Spoofing: When dial-up modems were popular in the period 1996–2000, scammers realized that when they used fake caller IDs, they could deceive the recipient about the identity of the caller. At the same time, local networks were exposed to ARP-based spoofing infections, which allowed the attackers to intercept the LAN traffic under the guise of gateways. This trend of office-based computing made the staff ill-prepared to deal with identity manipulation, thus presenting criminals with many opportunities for getting in.
3. Website Spoofing & Phishing Surge: Due to the increase of e-commerce and online banking in the period (2001–2010), criminals shifted their focus to website clones and SSL certificates. They took advantage of brand familiarity where they created domain names or used email templates that resembled those of legitimate companies. This period marked the beginning of the most advanced social engineering techniques that combined deception with newly discovered exploits. The threat of infiltration increased even more when businesses shifted to digital commerce, and financial transactions became targets for criminals.
4. Advanced DNS & BGP Spoofing: The next decade (2011–2020) witnessed the advancement of more complicated infiltration angles. Cybercriminals use Domain Name System (DNS) poisoning or Border Gateway Protocol (BGP) route hijacking to redirect the traffic to the wrong destinations. Similarly, large-scale data breaches involving large corporations demonstrated that various types of spoofing could attack internal routers or wide-area networks. Enterprises started to implement zero-trust architectures and temporary environments to minimize the time of exposure, but were still unable to manage multi-vector deception well.
5. AI-Driven Spoofing & Deepfake Tools: In recent years, criminals have been using AI to create quite realistic messages or even voice calls impersonating staff or brand personalities. This infiltration wave combines traditional identity theft with the modern trick of creating illusions, allowing criminals to progress to the next level of trust manipulation. The spoofing meaning has expanded and encompasses voice, video, or real-time collaboration platforms that need threat intelligence to identify abnormalities. Moving forward, scanning and policies must be further developed to counter the criminals’ evolving spoofing tools.

Difference Between Spoofing vs Phishing

While spoofing and phishing are similar, they are two different types of infiltration strategies. Phishing is more about deceiving people into providing certain information, such as usernames, passwords, credit card numbers, or personal information through links. On the other hand, spoofing focuses on identity or channel deception, where the email headers, IPs, or domain names are forged to make the recipients or endpoints believe the received messages are legitimate. In other words, phishing is the broader infiltration attempt, while the answer to the question ‘What is a spoofing attack?’ is more specific and refers to the forging of credentials, domains, or user identities for the purpose of infiltration. These two techniques are often combined, where the attacker creates a fake brand to trick people into providing personal details.

In certain infiltration scenarios, malicious actors may exclusively aim to deceive by falsifying IP addresses or DNS records to misdirect traffic or capture data, even if they are not actively stealing login credentials through conventional phishing techniques. However, some phishing attempts could be less dependent on the technical details being forged, but rather rely on social engineering or fear to manipulate the users. In a practical context, spoofing can be the “engine” that drives phishing since it guarantees that the infiltration message is authoritative. Both infiltration types thrive when there are no strong countermeasures, such as DMARC for email or DNSSEC for domain name resolution. Altogether, these infiltration threats must be fought jointly because criminals can switch from identity theft to large-scale theft of data or sabotage in a short time.

Types of Spoofing

In the context of cyber security, spoofing uses various techniques to forge the identity of a user and gain access to a system, deceive the recipient, or steal data. Since there are different types of spoofing, organizations can combat infiltration through email, IP, ARP, and more. In this article, we examine seven common types, all of which present different problems of infiltration and call for specific countermeasures.

1. IP Spoofing: Attackers modify the IP packet headers in order to make the traffic appear to be coming from trusted hosts or IP addresses. This invasion strategy bypasses network-based security measures such as filters or load balancers and allows criminals to gain access. Some of the advanced infiltration techniques also include partial IP fragmentation to bypass intrusion detection systems. These spoofs can be prevented by enforcing stateful inspection, using ephemeral tokens, or performing advanced routing checks.
2. Email Spoofing: Criminals can use fake email addresses or server data and put the “from” addresses that resemble familiar senders. This kind of infiltration usually serves as the foundation of phishing attacks, where the recipients are lured into trusting the attachments or links. A good DMARC, SPF, and DKIM implementation is effective in preventing infiltration by authenticating the domain. However, staff training is still important: if employees are careful, the probability of infiltration is low.
3. Caller ID Spoofing: Telephonic penetration involves disguising the caller ID to make it appear as though the call is coming from a familiar number or even a local number. Hackers use confidence — employees recognize the name of the boss or the local number on the phone, and then they follow instructions. This type of infiltration angle relies on real-time pressure; voice calls or callback policies can prevent it. Implementing staff awareness and using sophisticated phone systems minimizes the rate of infiltration success.
4. Website Spoofing: Phishing is when the attacker imitates the look and feel of a genuine website or registers domains that are very similar to the original site with slight spelling differences or an alternative domain extension. Users arrive at these pages, recognize brand logos, and input their credentials, thus being compromised. SSL certificates can also be forged or obtained for a low price, which also strengthens the fake sense of credibility. These attacks can be prevented by monitoring the domain continuously, using sophisticated browsing filters, or training the users.
5. GPS Spoofing: Besides network infiltration, criminals can change satellite signals or local broadcasts to change location information. This angle of infiltration can affect navigation-based services, shipping routes, or geofencing-based security triggers. GPS-dependent systems must check signals for accuracy or use anti-spoofing devices to enhance position authenticity. As IoT develops, the issue of infiltration through GPS spoofing is even more critical for supply chains and UAVs.
6. ARP Spoofing: In local networks, ARP is used to map IP addresses to MAC addresses and if the attackers put fake entries in the ARP cache, then they can redirect the data flow. This infiltration approach is normally used in shared LANs, which can allow criminals to intercept or alter the traffic. Applying dynamic ARP inspection, strict VLAN isolation, or temporary device utilization can be an obstacle to infiltration. It is noteworthy that cyber attackers use ARP forging as a part of other attack vectors to provide deeper data exfiltration.
7. DNS Spoofing: DNS spoofing is achieved by altering the DNS resolver records or poisoning the caches to redirect domain queries to the attacker’s IP address. In this case, victims get to see the genuine domain names, but end up on the infiltration sites and get to provide their credentials or other information. DNSSEC adoption, the use of DNS for temporary content, and improved detection affect the success of infiltration at the domain resolution layer. This remains a powerful attack vector if organizations do not use additional checks to ensure that they are performing legitimate DNS queries.

How Does Spoofing Work?

Although each type of spoofing has its own strategies, ranging from forging IP packets to mimicking domain names, the essence of infiltration is the same: criminals deceive systems or users by imitating identity indications. Below, we break down four key facets that tie these infiltration attempts together, explaining how they bypass conventional security measures.

1. Crafting False Identities: Bogus information is collected by the attackers on the brands, staff, or domain records, and then fake addresses, phone numbers, or URLs are created. Some infiltration attempts also incorporate stolen SSL certificates or compromised user tokens. If the recipients or devices accept these false signals, criminals can proceed with their attacks, even getting past filters or authentication gates. Sustaining the domain or identity verification procedures assists in preventing these illusions.
2. Exploiting Trusted Protocols & Gaps: Some of the older protocols, such as ARP or SMTP, do not have strong authentication mechanisms incorporated into them. Malicious actors insert forged headers or requests into these channels, thus allowing infiltration to go unnoticed unless additional measures are implemented. Likewise, the use of fake DNS or certificates also exploits reliance on automated systems. In successive expansions, organizations employ transient tokens and advanced encryption to frustrate incursion from these structural vulnerabilities.
3. Leveraging Social Engineering & Urgency: Even optimally configured computers might be compromised if an employee accepts a request from a “CEO” or “vendor.” Spoofing illusions are used alongside psychological tricks such as urgent wire requests and dramatic warnings to compel action. This infiltration tactic works where users are not careful or pressed for time, thus ignoring methodical policy checks. By frequent training of staff and having sound policies and controls, the chances of infiltration can be greatly minimized.
4. Pivoting Once Inside: Once cybercriminals gain initial access to a network or a specific user account, they are likely to elevate their privileges or establish a backdoor to allow them to easily penetrate the network again. This infiltration cycle may involve creating new credentials or subdomain DNS entries in order to extend control. By synchronizing infiltration illusions with deeper code manipulations, attackers camouflage malicious traffic or exfiltrate data covertly. These ongoing infiltration patterns are easily detected through the monitoring of logs, usage of ephemeral data, and correlation at an advanced level.

Stages of a Spoofing Attack

Spoofing, as a common type of infiltration, also follows a cycle of stages, ranging from reconnaissance to exploitation. By understanding each stage, defenders can identify infiltration signs and localize malicious behavior before it proliferates. In the following sections, we identify five key stages that are normally implemented by criminals in spoofing attacks.

1. Reconnaissance & Data Gathering: Cybercriminals gather information on what they want to steal, for example, domain data, staff’s LinkedIn accounts, or brand logos. This might also include a probe against any open ports or, in any case, potentially compromised credentials. When enough data has been gathered, the criminals decide in which area of spoofing is best suited for infiltration, whether it is in the email, IP, or domain forging. Preventing recon attempts or limiting the data available to the public helps reduce the success rates of stage one infiltration.
2. Spoofing Techniques & Delivery Channel: Using brand knowledge, attackers then create their messages in the form of an email, a DNS record, or a phone call. They may even create domain names that look like genuine ones or mimic the same staff signatures. This infiltration step involves choosing a distribution vector, which can be any of the following: mass e-mailing, infected SMS gates, or DNS spoofing. Here, at the crafting stage, organizations can delay infiltration by confirming domain ownership and searching for domain clones.
3. Launching the Attack: Criminals send fake messages, e-mails, phone calls, or DNS tampering, intending that the target company’s personnel or systems will take the messages at face value. Some of them also deliver payloads or demand an immediate transfer of money as soon as the victim is infiltrated. The infiltration effect is magnified if many of the recipients reply or fail to check the authenticity of the messages. Using real-time filters for e-mail or advanced checks for caller identification can significantly decrease the chances of infiltration at this stage.
4. Exploitation & Data Extraction: After gaining unauthorized access to the system, through methods such as stealing user credentials or exploiting network trust, attackers can elevate privileges, intercept communications, or exfiltrate data. They could also leave behind malware that provides backdoor access for continuous penetration or switch to other machines. The presence of internal logs can stay unnoticed for months or staff can be untrained, and infiltration will last for a long time. The quick detection and account lockouts help prevent the infiltration from aggravating or extending to other allied networks.
5. Covering Tracks & Repeat Attacks: Lastly, criminals may attempt to delete logs, restore DNS settings to a previous state, or transfer stolen information to other channels in order to not be easily tracked. Some infiltration cycles may also depend on the compromised environment to conduct further impersonations. If organizations do not have ephemeral usage or advanced correlation, infiltration can be partly concealed and continuous sabotage occurs. Prevention of such exposures requires a good logging system, forensic analysis, and staff awareness to ensure that the vulnerabilities are closed for good.

Spoofing Attack Examples

Here are classic examples of spoofing attacks and what happened recently:

• In February 2024, fraudsters spoofed Pepco Group's internal emails and walked away with €15.5 million. They impersonated real employees, sent invoices and payment requests that looked legitimate, and the finance team approved transfers without question. The attackers had studied the company's payment processes—they knew the timing, the amounts, who typically sends these requests. By the time anyone caught on, the money was gone.
• Change Healthcare learned a brutal lesson the same month. Attackers sent phishing emails with spoofed sender information to employees. That single entry point led to a ransomware breach affecting over 100 million Americans and crippling healthcare payment systems nationwide. One spoofed email. Millions of lives disrupted.
• Voice spoofing is getting scarier. Banks report over 10% experienced deepfake vishing attacks in 2024, where criminals used AI to clone executives' voices and call finance teams demanding urgent transfers. Average loss per incident: $600,000. The technology costs attackers as little as $50 per campaign.
• In August 2024, a United Airlines flight from New Delhi to New York received fake GPS signals the entire flight—originating from the Black Sea region. By mid-2024, over 1,100 flights daily faced GPS interference. Ships report the same problem. Attackers  are now sending false navigation data that makes pilots and captains distrust their instruments.

Spoofing Detection & Removal

How to get rid of spoofing? Well, it might not be a simple process but you can. Whether an attacker spoofs a domain name, an IP packet header, or the phone caller ID, timely detection of spoofing is vital. When infiltration is detected, it is critical to act quickly, check for ransomware or other actions, and clean it up so that those who seek to take advantage of the situation cannot use the same tricks over and over again. In the following section, we outline four key steps that link infiltration detection to sustainable remediation.

1. Advanced Email & Domain Security: Ensure that SPF, DKIM, and DMARC are implemented to ensure that only authorized domain addresses are accepted to prevent impersonation attempts. It makes sure that newly registered domains similar to the brand also get detected in real-time. For sensitive transactions, staff also use ephemeral usage or pinned domain references. This synergy quickly shuts down the invasion at the email gateways, preventing forged messages from passing through.
2. Behavioral Analytics & SIEM Integration: Gather audit data from mail servers, DNS queries, or user logins and feed them into an SIEM or correlation engine. If there are such infiltration anomalies, for example, multiple invalid login attempts from suspicious IP ranges, then the alert is flagged and gets staff attention. Through cross-referencing patterns, the attempts at infiltrating that do not go through the normal scanning cannot sustain stealth. Across multiple iterations, staff integrate infiltration detection with advanced correlation for immovable fortification.
3. Root Cause Forensics & Patch Deployment: In the event that infiltration is achieved, detailed spoofing analysis is essential to determine the manner in which the illusions breached the current security measures. It might have been that some criminals took advantage of outdated software or personnel who lacked adequate training. By applying patches or policies that target specific infiltration vectors, an organization mitigates continuous sabotage. Staff also use ephemeral usage for dev or test systems to limit the angles of exposure from less protected environments.
4. Staff Training & Incident Debriefs: Last but not least, any infiltration event or near-miss indicates that either the users are not aware of the risks or the system is not designed well enough. In daily operations, staff training on how to verify the senders of emails or how to block suspicious calls also helps in preventing infiltration. Incident debriefs identify any illusions that the criminals used during the process, modifying the future scan or the user check. This approach combines the concepts of infiltration detection and continuous improvement to make it almost impossible for an illusion to be used more than once.

Key Risks and Impact of Spoofing

The key risks and impacts of spoofing are as follows:

Network Disruptions

Technical spoofing attacks like IP spoofing and ARP spoofing can launch distributed denial of service attacks. It can overwhelm networks with a lot of traffic and cause operational downtimes and even service outages.

Safety Hazards with GPS Spoofing

If you are working in critical sectors like maritime, transportation, and aviation, GPS spoofing can send false location information. It can lead to navigation errors, potential collisions, and other safety risks.

Financial Fraud and Losses

Spoofing can lead to large sums of money being transported without authorizations. Attackers can use fraudulent accounts and steal credit card information from consumers.

Distributing Malware

Spoofed communications can trick users into downloading malware and spreading it. It can also automatically happen in the background once they execute the malware code. There's also a high risk of data and identity theft. You can lose your login credentials, personal data, financial details, and other information.

Unauthorized Access

The person who's spoofing can impersonate you and gain unauthorized access to your networks, accounts, data, and systems. Anything can happen once they log in and gain entry. They can even escalate their attacks and move laterally across your networks if you're not careful, and even escalate privileges.

How to Protect Yourself From Spoofing Scams?

There is no foolproof way of protecting yourself 100% from spoofing scams because anything can happen from anywhere. That's the first thing you should be aware of. 

Now, you can follow some best spoofing attack prevention practices to stay safe and be vigilant:

• If you receive any emails or messages from suspicious sources, don't engage with them. Ignore them or if you have some doubts, you can just look up the official phone numbers and website addresses independently. Contact the person who's sending you the message directly to verify their request. So verifying the source is very important. 
• Second, never share sensitive information just like that, no matter how urgent it is. We know it can be tempting to act emotionally or at impulse, but that's exactly what this pooper wants from you. Think before you click or download anything. Remember that they are timing their attacks based on the different moods in your business.
• Don't carry out any sensitive activities on public Wi-Fi zones or unsecured networks. These can be vulnerable to man-in-the-middle attacks. You should also use a virtual private network to encrypt your internet connection for added security. Now, when it comes to examining emails, messages or any website links that are sent to you,
• Hover over the URL and check, but don't click on it. See if the website address starts with the https:// prefix and if it has a padlock icon in the address bar. This will tell you if the connection is secure. Next, check the sender's email address for any misspellings or variations. Some hackers managed to steal Microsoft users' Gmail credentials. They had spelled the M as an R and an N, to make the “RN” look like an M. People who looked at the emails at first glance and didn't pay attention to detail, they fell for it and ended up getting juked.
• So not only can attackers take advantage of spelling errors and mistakes, but they can also modify spellings in such a way that they look identical to the original address. So zoom in, take a clear look at it and don't react to any high pressure or urgent language. When it comes to your security software, you want to install and enable antivirus and anti-phishing solutions. This will keep your operating systems and software all up to date. 
• Don't answer unknown calls and if you receive any offers that are too good to be true, then they certainly are. So avoid them. You can also file a complaint with the FCC's Consumer Complaint Center in the US and report to your local law enforcement authorities in case you have gotten involved yourself in an incident or if you've lost money.

How to prevent spoofing attacks?

Here is how you can prevent spoofing attacks:

1. Implement Anti-Spam Measures (SPF, DKIM, DMARC): These frameworks authenticate the sender to alert the system administrators of the fake or unverified domain that the criminals imitate. This significantly reduces the infiltration attempts when enabled across all the mail domains. Regular log reviews avoid any misconfiguration of domains that would allow infiltration to occur.
2. Apply Zero-Trust & Strong IAM: Limit the use of privileged actions to only those that are protected by multi-factor authentication or temporary credentials. That way, even when attackers have fake user IDs, they cannot get to the escalation stage if each session is authenticated. Certain factors, which include well-documented role assignments and ephemeral tokens, restrain infiltration pivoting.
3. Adopt DNS & Network Hardening: DNSSEC, dynamic ARP inspection, and advanced route validations prevent infiltration from DNS or ARP forging. When it comes to domain records and MAC addresses, there are real-time checks to counteract the actions of the attackers. This approach takes infiltration prevention beyond the client endpoints all the way to internal networks.
4. Educate Staff on Spoofing Tactics: The final defense against cyber threats may fall to employees, such as finance workers authorizing wire transfers or developers noticing new domains within applications. Thus, phishing drills and using scenarios in training lower the probability of infiltration greatly. Encourage the personnel to challenge any phone call, letter, or SMS that may urge them to take immediate action.
5. Real-time Threat Feeds & Alerts Monitoring: Spoofing infiltration can be quick, especially if the criminals take advantage of newly discovered holes or domain illusions. Through the integration of SIEM solutions and advanced watchers, the staff is able to identify abnormal patterns of mail traffic or domain queries. This means that quick response time prevents infiltration from growing into large-scale sabotage.

FAQs on Spoofing

Is Spoofing Illegal?

Yes, spoofing is illegal in the majority of jurisdictions, especially when it is carried out to commit fraud or modify data. There are prohibitions against fraudulent acts aimed at misleading victims and acquiring unauthorized access to systems. If you wish to find out whether spoofing is legal or illegal where you are, you can consult a cybersecurity specialist or attorney.

How Spoofing is Used in Cyber Attacks?

Attackers use spoofing to trick victims by forging email headers, IP addresses, or caller IDs. They want to appear trustworthy while delivering malicious links or payloads. In many cases, they combine spoofing with phishing campaigns, so victims will click or download harmful files. You can see it happen in trojanized downloads or social engineering schemes. If you fail you to confirm the sender’s authenticity, you risk falling for these threats.

How to stop spoofing email?

First, implement email authentication mechanisms such as SPF, DKIM, and DMARC. In this way, you are sure that emails are coming from genuine servers. Second, use secure email gateways and spam filters to identify malicious traffic. Update your systems and scan emails before opening attachments. If you have to handle sensitive information, you need to authenticate the sender’s identity and never open suspicious files or links.

What is a spoofing scam?

A spoofing scam is an illegal scheme that uses false data to impersonate a legitimate source. Senders may impersonate other addresses, numbers, or sites to obtain login credentials or financial information. Once they have deceived victims, they may hack into systems or steal funds. You can detect such scams by strange messages or unwanted requests. If you do not check for authenticity, you can risk exposing your personal information to strangers.

How do I defend against spoofing?

You can protect yourself by being vigilant and probing suspicious communications. Employ security software that blocks or flags suspicious messages, such as secure email gateways and current antivirus software. Patch your computers, and scan your network for unusual patterns. If you must exchange sensitive information, ensure you verify the source. Educate your employees on phishing techniques and social engineering attempts.

What is Text Message Spoofing?

Text message spoofing is when attackers fake the sender's phone number to make it look like the text came from someone you trust. The attacker will send you a message that appears to come from your bank, a delivery service, or someone you know. They're trying to trick you into clicking a link or responding with personal information. 

The spoofed text might ask you to update payment details or verify your account. You might see a message that looks urgent, like a package delivery notification or a security alert. These messages often contain malicious links that install malware or lead to phishing sites.

What is email spoofing?

Email spoofing is where the hackers impersonate email headers or sender details to make the messages look real. They do it to trick the recipients into opening malicious links, downloading malicious files, or revealing sensitive information. It is a favorite tactic for phishing campaigns and tends to deceive spam filters if not handled correctly. If you need to share confidential information, check the authenticity of the sender first. It will safeguard your information from the attackers.

What is ARP spoofing?

ARP spoofing is a technique where attackers send false ARP (Address Resolution Protocol) messages across a local network. They do this to link their MAC address with a legitimate IP address, so data intended for that IP goes to them instead. This allows them to intercept or modify sensitive information passing over the network. If you fail you to secure your internal environment, you risk losing data to these attackers.

What is DNS spoofing?

DNS spoofing happens when attackers redirect you to a fake website by changing DNS records or intercepting DNS queries. When you type a website address, DNS translates it to an IP address. The attacker will intercept this and send you to a malicious site instead of the real one. You might not notice because the fake site looks exactly like the real one. 

They will then harvest your login credentials or install malware on your device. DNS spoofing can affect many users if the attacker compromises a DNS server. You can protect yourself by using DNSSEC, which verifies DNS records are legitimate and haven't been modified.
