DNS security is an underrated risk. The technology is structured in a way that allows DNS packets to flow through the network without prior scrutiny. Moreover, DNS activity within networks is rarely monitored, creating a blind spot in cybersecurity. This oversight is significant, as 88% of companies suffer from DNS attacks every year, according to a 2023 report by EfficientIP. Despite the high risk, one-third of these attacks could be prevented at the DNS level, as highlighted by a 2023 study by Cisco.

What is inside DNS traffic

DNS traffic can carry a variety of parameters that play an important role in the exchange of information between clients and DNS servers. These parameters may include the type of request, the server’s response code, TTL (time to live of the record in the cache), transaction identifier, query options, etc. DNS queries are essential components of DNS traffic, involving requests made by clients to DNS servers to resolve domain names into IP addresses.

Moreover, DNS traffic can carry data about the IP addresses of DNS servers, information about network traffic, the location and configuration of domains, as well as much more that helps ensure the efficient operation of the Internet and its security. The DNS resolver plays a crucial role in processing these DNS queries, facilitating the exchange of information between clients and DNS servers. Here is a list of the main parameters:

Threats at the DNS level

Malware

Malicious software, or malware, includes various cyber threats such as viruses, trojans, spyware, adware, and techniques like DNS cache poisoning, where malware redirects users to malicious sites by exploiting DNS vulnerabilities. It can cause significant issues, from minor annoyances to major financial losses, by altering browser settings, using up computing resources, and collecting sensitive user data like passwords and credit card numbers.

DNS protection is crucial in combating malware by:

• Blocking access to malicious domains to prevent malware communication and data breaches.
• Monitoring for abnormal behavior to detect malware presence.
• Providing network activity logs to enhance incident response and mitigate security breaches quickly.

Ransomware

Ransomware is malicious software that encrypts a computer’s files, rendering them inaccessible, and may lead to data breaches. The malware demands ransom for decryption, impacting both individuals and business operations.

DNS protection aids against ransomware by:

• Blocking access to ransomware’s command and control servers to disrupt its communication.
• Preventing devices from connecting to malicious websites and email attachments that could initiate an attack.
• Enabling rapid, automated threat detection and alerts, facilitating a swift response to potential ransomware activity.

Phishing and Typosquatting

Phishing and Typosquatting are forms of cyber deception aimed at stealing sensitive information through fake websites and misspelled domain names. DNS spoofing is another method where attackers manipulate DNS records to redirect users to fraudulent sites, often for malicious purposes such as phishing, malware distribution, or denial-of-service attacks. These practices can compromise personal and corporate security, leading to financial losses and reputational damage.

DNS protection helps combat these threats by:

• Preventing access to fake websites designed to mimic legitimate ones, safeguarding user credentials.
• Utilizing algorithms to identify and block deceitful domains that resemble legitimate sites, protecting users from fraud.

Botnet, Cryptojacking, and C2C

Botnets, composed of internet-connected devices infected with malware, can perform various malicious activities, including DDoS attacks, data theft, and illegal cryptocurrency mining, leading to energy and productivity loss and potential financial and reputational damages. Botnets and C&C servers often utilize DNS requests to communicate and control compromised devices, highlighting the need for robust DNS protection strategies.

DNS protection helps by:

• Blocking access to known command and control (C&C) servers to disrupt botnet communications.
• Detecting and preventing connections to suspicious domains associated with botnets or C&C servers.
• Identifying unusual patterns that may indicate botnet presence to prevent system infections.

Parked Domains

These are domain registrations on DNS servers offering parking services, not actively used but may host illegitimate content at a remote server at any time. SafeDNS implements a verification pipeline using real-time data from various sources to monitor new domains and their content, identifying and filtering out illegitimate resources at an early stage. The system establishes domain-IP-autonomous system (AS) relationships, which helps in the early detection of malicious domains.

DGA and DNS Tunneling Attacks

DGAs create numerous domain lists to maintain botnet communication and evade security measures. They don’t directly harm networks but enable the infiltration of malicious software and impede its removal, potentially resulting in corporate network damage.

DNS protection contributes by:

• Detecting and blocking DGA-generated domains using machine learning and traffic analysis, ensuring queries are directed to the correct IP address by verifying information with the authoritative DNS server.
• Monitoring and obstructing abnormal DNS activity that could signify DNS tunneling.
• Maintaining a database of known DNS tunnels to block unauthorized connections and data transmission.

An authoritative DNS server plays a crucial role in this process by holding the official and up-to-date information about a domain name’s IP address, ensuring that DNS queries are resolved with the correct IP address, which is essential for preventing DNS tunneling and DGA threats.

Threats at the DNS level are a major concern because they can disrupt operations, compromise sensitive data, and damage reputations.

The Cybersecurity Puzzle

It is a sad fact that cybersecurity is no longer a buzzword but a stark reality, especially for the 73% of small businesses globally that recognize it as their most significant risk. According to a recent McAfee and Dell Technologies study, nearly half of these businesses have already been scorched by the fire of cyberattacks, leading to substantial financial losses, eroded customer trust, and hampered operating efficiency. What is more alarming?

The Email Gateway: Friend or Foe?

Email has become the battleground for cybersecurity, with phishing being the weapon of choice for many cybercriminals. But here is the million-dollar question: are spam filters enough to protect us from these threats? Let’s break it down.

There are three main types of spam filtering solutions or tools.

• Built-in Email Filters: Offered by giants like Google, these are the first line of defense against spam and phishing attempts.
• Gateway/Cloud-Based Filters: These work by filtering both inbound and outbound messages that look suspicious, adding an extra layer of protection to email service providers’ built-in filters.
• Desktop Spam Filters: Personalized and configured by the user, living right on your desktop.

While these filters do a commendable job of blocking phishing and spam emails, some sneaky phish still manage to slip through the net.

Why do some of the phishing emails bypass filters?

Phishing emails, despite the advancements in email security, spam detection and filter technology, often manage to slip through the cracks due to various ingenious tactics employed by cybercriminals. While email filters utilize several methods to detect suspicious emails, hackers continually evolve their techniques to bypass these defenses.

Here are some common methods used by email filters to detect phishing emails:

• Keyword Analysis: Filters scan emails for specific keywords commonly associated with phishing, such as “you won a prize,” to flag them as potential threats.
• Image-to-Text Ratio: Emails containing a high percentage of images and minimal text are flagged, as this tactic is often used to evade text-based filters.
• White Text Detection: Filters look for hidden text, such as white text on a white background, commonly used to hide malicious content from plain sight.
• IP Trust Level: The trustworthiness of the sender’s IP address is evaluated, with emails originating from suspicious or low-trust IPs being flagged for further scrutiny.
• From Field Analysis: Emails with randomized or nonsensical sender addresses, like “asdsdf@mail.com,” are often considered suspicious and subjected to closer inspection.

However, despite these measures, phishing emails can still bypass filters due to their primary tactic: enticing recipients to click on malicious links within unwanted emails. Unlike other content within the email, the link itself may not always be thoroughly scanned by filters. This loophole is precisely what phishing attackers exploit, knowing that the real danger lies in convincing recipients to interact with the malicious content beyond what the filters can detect.

Consider this scenario: You’re working in the accounting department and receive an email seemingly from a familiar colleague, containing a link to an invoice. Since you regularly receive such emails from this colleague, there’s no cause for concern. Moreover, the email spam filter may not detect anything inherently suspicious about it. However, unbeknownst to you, earlier that day, your colleague’s email account was compromised by a hacker who sent out the phishing email in their name. In this scenario, the email manages to bypass both your vigilance and the email filter, illustrating the cunning tactics employed by cybercriminals.

In essence, while email filters serve as a crucial line of defense against phishing attacks, their effectiveness is not absolute. Hackers constantly adapt and refine their methods to circumvent these filters, making it imperative for individuals to remain vigilant and cautious when interacting with emails, and spam messages even those that seem benign at first glance.

So, what is the solution? Enter Web Filtering

This is where web filtering steps into the spotlight, offering a robust shield against the phishing attempts that dodge email filters. Consider SafeDNS, a solution with over 6 million users around the world, which blocks a whopping 20% more phishing sites than its competitors. But why stop there? The benefits of web filtering extend well beyond just email protection:

• Blocks Newly Generated Phishing Links: SafeDNS does not just block emails and known threats; it quarantines new domains until they are verified, protecting you from the latest scams.
• Provides Secure Communication: It is not just about emails. You can catch a phish through messaging apps, corporate chat platforms, and similar communication tools.
• Enables Safe Surfing: A web filter prevents you from accidentally wandering into malicious territories while browsing the internet.
• Saves Internet Traffic: By filtering out unwanted content, web filtering helps conserve your internet bandwidth, making your online experience smoother and more efficient.
• Enhances Productivity: The installed web filter does not simply restrict access to certain types of resources. It helps employees remain productive, not letting them get distracted by social media or streaming platforms.

The Real-World Impact

Imagine this: you are running a small business, and cybersecurity is not exactly your forte. You have got spam filters up and running, but then comes the curveball—a phishing attack that slips through the cracks of spam protection, leading to compromised customer data, lost passwords, or worse. It is not just a hit on your finances; it is a blow to your reputation. Can you afford to take that risk?

Strengthening the Fortress

So, is it enough to rely solely on spam filters in this age of escalating cyber threats? The answer is a resounding no. With almost half of all ransomware attacks starting with phishing, and the most common catch being through emails, strengthening your defenses with web filtering is not just a good idea—it is essential.

Why Settle for Less?

When we talk about cybersecurity, why settle for a single layer of protection? With the advancements in web filtering technologies, such as those offered by SafeDNS, you are not just protecting your network; you are ensuring peace of mind for yourself, your employees, your partners, and your customers.

In the digital age, the question is not whether you can afford to implement web filtering; it is whether you can afford not to. With cyber threats evolving by the day, can you afford to leave your digital doors unlocked, or will you choose to strengthen your defenses and safeguard your online presence?

To sum up, the rise in phishing attacks is a clarion call for enhanced cybersecurity measures. While email spam filters serve as a necessary barrier against threats, they are not infallible. Web filtering, particularly solutions like SafeDNS that offer advanced protection against new and emerging threats, represents a critical component of a comprehensive cybersecurity strategy. It is not just about blocking malicious emails; it is about creating a safer, more secure digital environment for all users. In the fight against phishing and other cyber threats, web filtering is not just an option; it is a necessity.

The Domain Name System (DNS) guides us through the vast expanse of the internet. It is the unsung hero, translating human-readable domain names into the machine-readable IP addresses that our devices understand. But what happens when this essential process is not as private as we would like it to be? The implications for security, privacy, and even human rights can be profound.

The Risks of Plaintext DNS Queries

By default, DNS queries—the questions your computer asks to find the address of a website—are sent in plaintext. This means they are as open to prying eyes as a conversation in a crowded café. Whether it is a network administrator, an Internet Service Provider (ISP), or a more nefarious actor, anyone with the right tools can eavesdrop on these conversations. It is like announcing your destination aloud before stepping into a secret passage. The risks of doing this range from benign but targeted advertising to more sinister issues like government censorship or cybercriminals tracking your online habits.

DoT and DoH for DNS Privacy

Enter the superheroes of DNS privacy: DNS over TLS (DoT) and DNS over HTTPS (DoH). These protocols are the digital equivalent of putting our postcards in envelopes, shielding our queries from those who might want to sneak a peek.

DoT takes our DNS queries and wraps them in the security of TLS (Transport Layer Security), the same protocol that HTTPS websites use to keep your data safe. When a device initiates a DNS query, it establishes a secure connection with the DNS server through a TLS handshake, ensuring the confidentiality and integrity of the exchange. DoT prevents eavesdropping by encrypting the data, making it indecipherable to unauthorized parties.

It is like sending your DNS queries in an armored van, ensuring they reach their destination without interference. However, DoT operates on a dedicated port (853), any user with access to the network can see DoT traffic in and out, even if no one can see inside since if the requests and responses themselves are encrypted.

On the flip side, DoH sends these encrypted DNS queries over HTTP or HTTP/2. This means they travel on the same roads as regular internet traffic (port 443), blending in with the crowd. DoH allows users to bypass network restrictions and censorship, making it difficult for intermediaries to selectively inspect or manipulate DNS queries. To a network observer, DoH traffic is indistinguishable from any other secure website visit, making it a master of disguise.

Both DoT and DoH serve the same noble purpose: to protect the privacy and integrity of your DNS queries. They ensure that no one can tamper with or spy on your internet navigation. Yet, their distinct paths—DoT with its exclusive route and DoH camouflaged among the masses—offer different advantages depending on what level of privacy, security measures and compatibility you seek.

SafeDNS also provides the DoT feature, complementing the DoH (DNS over HTTPS) support that is typically enabled by default in most browsers. For guidance on activating DoT through the SafeDNS dashboard, please refer to our detailed instructions available here.

As we stand at this crossroads, the question is not just about which protocol to choose. It is about recognizing the importance of DNS privacy and taking steps to protect it. Whether you lean towards the visibility and security of DoT or the stealth and integration of DoH, the crucial thing is to be aware of your choices and their implications.

In the grand tapestry of the internet, where every click, search, and query weaves a thread, ensuring these threads are secure and private is vital. It is about more than just safeguarding data; it is about preserving the freedom and trust that lie at the heart of the digital age. As we continue to navigate this ever-changing landscape, let us do so with an eye towards not just where we are going, but how safely and privately we can get there.

The Internet has become something like the very air we breathe, ensuring its safety is paramount. Yet, lurking within this indispensable resource is a sophisticated threat known as Domain Generation Algorithms (DGA). But what exactly is a Domain Generation Algorithm (DGA), and why is it a topic of concern for cybersecurity teams and everyday internet users alike? Let’s embark on a journey to demystify DGA, its implications, its threat actors and the innovative measures being taken to combat it.

How DGAs Operate

Consider a machine infected with a botnet, like a sleeper agent awaiting orders. If this agent’s meeting point is compromised, they can no longer receive commands, rendering them ineffective. It resembles knowing exactly where a spy is going to drop their secrets. Once that location is discovered and watched, the spy’s effectiveness is nullified. Hence, the logic behind DGAs: never stick to one domain. By constantly changing domains based on a specific algorithm, these digital spies stay one step ahead, making it challenging for cybersecurity teams to catch them.

The Challenge of Detection: Separating Wheat from Chaff

Yet, the task of detecting malicious domains generated by these algorithms is not as daunting as one might think. The real challenge lies in distinguishing between DGA-generated domains and legitimate technical domains. It looks like trying to find a needle in a haystack, except some of the needles look remarkably similar to the hay. For example, Microsoft’s technical domains could easily be mistaken for those generated by DGAs, leading to a plethora of false positives. It’s a fine line to walk, requiring not just technical prowess but also a deep understanding of both legitimate domains and malicious digital behaviors.

The role of DGA in cybersecurity

The Domain Generation Algorithm (DGA) has been a big deal in malware for the past ten years. It’s crucial to understand how DGA attacks work to keep your network safe from malware. Security software can quickly block malware that depends on a fixed domain or static IP addresses. Essentially, cyber attackers use DGAs to constantly create malicious domains and IP addresses for their malware’s control servers. This makes it hard for defenders to catch them because they keep changing domains. Even though DGAs have been around for a while, security researchers say they’re still tough to deal with. But new technologies are being developed to tackle them better.

DGAs have been a headache for malware victims for over a decade. Big malware attacks like Conficker, Zeus, and Dyre have used DGAs to keep changing domains and their control servers’ addresses. Normal security software can’t keep up because the malware keeps switching domains. But now, new technologies that use big data and machine learning are being developed to predict and stop these attacks before they happen. They aim to make it harder for attackers to set up malicious sites in the same domain names in first place.

SafeDNS’s Strategies Against Domain Generation Algorithms

In response to this challenge, SafeDNS has pioneered an approach by creating a separate category for DGA domains. This initiative is not just about enhancing cybersecurity measures; it is about adapting to modern digital threats. DGA is not limited to shadowy corners of the internet; it is actively used by a wide array of platforms, including numerous gambling sites. Take 1xBet, for instance. This application leverages automatically generated domains to ensure its continuous operation, making it a tough nut to crack for those looking to block it. However, the domainexperts at SafeDNS are not easily outmaneuvered. Through meticulous analysis of application traffic and the intricate web of connections between servers, IP addresses, and generated domains, our experts manage to detect about 10 new domains daily for only this particular application, blocking them effectively and safeguarding users.

The Widespread Use of a Domain Generation Algorithm (DGA)

The use of DGA extends far beyond gambling platforms, playing a crucial role in the operation of botnets and corresponding cyberattacks. These automatically generated domains can be employed for a variety of purposes, ranging from benign technical needs to more nefarious activities. It underscores a fundamental truth about the digital age: the tools and technologies developed can serve both to advance and to undermine our collective security.

So, what does this all mean for the average internet user and for organizations striving to protect their networks? It highlights the need for constant vigilance, innovation, and adaptation. The creation of a separate category for DGA domains by SafeDNS is a testament to the proactive stance required to stay ahead of cybercriminals.

But let’s pause for a moment to ask ourselves a question: In the grand scheme of things, what can we, as individuals and as a community, do to contribute to the safety and security of our digital world? It begins with awareness of cyber attacks, understanding the nature of threats like DGA, and supporting the efforts of cybersecurity professionals. By staying informed about security solutions and adopting safe online practices, we play a part in this vast ecosystem, helping to safeguard not just our own digital footprint but also contributing to the broader effort to secure the internet for everyone.

The story of DGA is a fascinating glimpse into the ongoing struggle between cybercriminals and cybersecurity experts. It is a reminder that adaptation and resilience are key to overcoming challenges. SafeDNS’s innovative approach to tackling DGA-generated domains exemplifies the kind of forward-thinking strategy that will define the future of cybersecurity. As we continue to deal with the complexities of the internet, let’s do so with a commitment to safety, security, and the collective well-being of our networks.
