How to protect endpoints from phishing emails with lookalike domains

Kaspersky experts have found that the service and e-commerce industry has become the most targeted by phishing attacks with domains that look legitimate. In Q3 2020, the sector accounted for 35% of all attacks that use this technique. This may be a result of the pandemic, as there has been a massive transition in the number of consumers relying on online services and shopping. Half (50%) of fake domains are only used once and 73% are active for just one day, which makes them very hard to detect. Automated multi-layered analysis is able to detect such attacks without compiling domain lists manually.

The lookalike technique means phishing emails are sent from a domain that looks like a legitimate web address, but in fact may have a minor spelling error (such as a missing letter). In many cases, a recipient is unlikely to notice the mistake, for example fraudsters will change @netflix.com to @netffix.com or use @kapersky.com instead of @kaspersky.com. The messages with lookalike domains pass authentication without any problems, have a cryptographic signature and do not arouse the suspicion of anti-spam systems.

Kaspersky’s research reveals which industries most often suffer from attacks with lookalike domains. In Q3 2020, services and e-commerce were hit the most, with IT & Telecom in second place.

The traditional method of detecting lookalikes is the manual insertion of all possible variants of fake domains into an anti-phishing solution, which is time consuming and not always effective, as some options may still be missed from the list. It is as if the police created an identikit of a criminal but were not sure about some of the facial features, so they had to make a hundred identikits with a wide range of options for the nose or eyes.

The technology which is more effective against phishing with lookalike domains includes several stages of analysis, helping to identify the fake by comparing a suspicious domain to legitimate ones, rather than a list of false ones.
When a letter from an unknown sender is delivered to an email inbox, it goes through all of the standard anti-spam filters. If nothing malicious is revealed, the domain analysis begins. During the first stage, the system compares the domain with all known lookalikes. If there are no matches, in the second stage, the system reviews information about the domain, such as registration details or certificates. If something looks suspicious, the investigation continues. In the third stage, the domain is compared with the list of known legitimate web addresses. This list is also composed automatically. If the system finds any similarity between the suspicious domain and a legitimate one, then the verdict will deem it as a ‘lookalike’.

This approach allows an anti-phishing solution to block attacks which use lookalike domains in real time when they first appear. It doesn’t require any manual actions, such as compiling a list of legitimate or possible lookalikes from the customer. All calculations are performed in the cloud and do not require additional computing resources from the client.

This approach is implemented in Kaspersky’s solutions with mail server protection and Kaspersky Security for Microsoft Office 365. To learn more about lookalike domains and the technology that can protect businesses from them

Protect and Secure Your Data

Cyber security is the practice of defending computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks. It’s also known as information technology security or electronic information security. The term applies in a variety of contexts, from business to mobile computing, and can be divided into a few common categories.

  • Network security is the practice of securing a computer network from intruders, whether targeted attackers or opportunistic malware.
  • Application security focuses on keeping software and devices free of threats. A compromised application could provide access to the data its designed to protect. Successful security begins in the design stage, well before a program or device is deployed.
  • Information security protects the integrity and privacy of data, both in storage and in transit.
  • Operational security includes the processes and decisions for handling and protecting data assets. The permissions users have when accessing a network and the procedures that determine how and where data may be stored or shared all fall under this umbrella.
  • Disaster recovery and business continuity define how an organization responds to a cyber-security incident or any other event that causes the loss of operations or data. Disaster recovery policies dictate how the organization restores its operations and information to return to the same operating capacity as before the event. Business continuity is the plan the organization falls back on while trying to operate without certain resources.
  • End-user education addresses the most unpredictable cyber-security factor: people. Anyone can accidentally introduce a virus to an otherwise secure system by failing to follow good security practices. Teaching users to delete suspicious email attachments, not plug in unidentified USB drives, and various other important lessons is vital for the security of any organization.

The scale of the cyber threat

The global cyber threat continues to evolve at a rapid pace, with a rising number of data breaches each year. A report by RiskBased Security revealed that a shocking 7.9 billion records have been exposed by data breaches in the first nine months of 2019 alone. This figure is more than double (112%) the number of records exposed in the same period in 2018.

Medical services, retailers and public entities experienced the most breaches, with malicious criminals responsible for most incidents. Some of these sectors are more appealing to cybercriminals because they collect financial and medical data, but all businesses that use networks can be targeted for customer data, corporate espionage, or customer attacks.

With the scale of the cyber threat set to continue to rise, the International Data Corporation predicts that worldwide spending on cyber-security solutions will reach a massive $133.7 billion by 2022. Governments across the globe have responded to the rising cyber threat with guidance to help organizations implement effective cyber-security practices.

In the U.S., the National Institute of Standards and Technology (NIST) has created a cyber-security framework. To combat the proliferation of malicious code and aid in early detection, the framework recommends continuous, real-time monitoring of all electronic resources.

The importance of system monitoring is echoed in the “10 steps to cyber security”, guidance provided by the U.K. government’s National Cyber Security Centre. In Australia, The Australian Cyber Security Centre (ACSC) regularly publishes guidance on how organizations can counter the latest cyber-security threats.

Types of cyber threats

Cyber threats - Cybercrime, Cyber-attack, Cyberterrorism

Cyber threats – Cybercrime, Cyber-attack, Cyberterrorism

The threats countered by cyber-security are three-fold:

  1. Cybercrime includes single actors or groups targeting systems for financial gain or to cause disruption.
  2. Cyber-attack often involves politically motivated information gathering.
  3. Cyberterrorism is intended to undermine electronic systems to cause panic or fear.

So, how do malicious actors gain control of computer systems? Here are some common methods used to threaten cyber-security:

Malware

Malware means malicious software. One of the most common cyber threats, malware is software that a cyber criminal or hacker has created to disrupt or damage a legitimate user’s computer. Often spread via an unsolicited email attachment or legitimate-looking download, malware may be used by cybercriminals to make money or in politically motivated cyber-attacks.

There are a number of different types of malware, including:

  • Virus: A self-replicating program that attaches itself to clean file and spreads throughout a computer system, infecting files with malicious code.
  •       TrojansA type of malware that is disguised as legitimate software. Cybercriminals trick users into uploading Trojans onto their computer where they cause damage or collect data.
  • Spyware: A program that secretly records what a user does, so that cybercriminals can make use of this information. For example, spyware could capture credit card details.
  • Ransomware: Malware which locks down a user’s files and data, with the threat of erasing it unless a ransom is paid.
  • Adware: Advertising software which can be used to spread malware.
  • Botnets: Networks of malware infected computers which cybercriminals use to perform tasks online without the user’s permission.

SQL injection

An SQL (structured language query) injection is a type of cyber-attack used to take control of and steal data from a database. Cybercriminals exploit vulnerabilities in data-driven applications to insert malicious code into a databased via a malicious SQL statement. This gives them access to the sensitive information contained in the database.

Phishing

Phishing is when cybercriminals target victims with emails that appear to be from a legitimate company asking for sensitive information. Phishing attacks are often used to dupe people into handing over credit card data and other personal information.

Man-in-the-middle attack

A man-in-the-middle attack is a type of cyber threat where a cybercriminal intercepts communication between two individuals in order to steal data. For example, on an unsecure WiFi network, an attacker could intercept data being passed from the victim’s device and the network.

Denial-of-service attack

A denial-of-service attack is where cybercriminals prevent a computer system from fulfilling legitimate requests by overwhelming the networks and servers with traffic. This renders the system unusable, preventing an organization from carrying out vital functions.

Latest cyber threats

What are the latest cyber threats that individuals and organizations need to guard against? Here are some of the most recent cyber threats that the U.K., U.S., and Australian governments have reported on.

Dridex malware

In December 2019, the U.S. Department of Justice (DoJ) charged the leader of an organized cyber-criminal group for their part in a global Dridex malware attack. This malicious campaign affected the public, government, infrastructure and business worldwide.

Dridex is a financial trojan with a range of capabilities. Affecting victims since 2014, it infects computers though phishing emails or existing malware. Capable of stealing passwords, banking details and personal data which can be used in fraudulent transactions, it has caused massive financial losses amounting to hundreds of millions.

In response to the Dridex attacks, the U.K.’s National Cyber Security Centre advises the public to “ensure devices are patched, anti-virus is turned on and up to date and files are backed up”.

Romance scams

In February 2020, the FBI warned U.S. citizens to be aware of confidence fraud that cybercriminals commit using dating sites, chat rooms and apps. Perpetrators take advantage of people seeking new partners, duping victims into giving away personal data.

The FBI reports that romance cyber threats affected 114 victims in New Mexico in 2019, with financial losses amounting to $1.6 million.

Emotet malware

In late 2019, The Australian Cyber Security Centre warned national organizations about a widespread global cyber threat from Emotet malware.

Emotet is a sophisticated trojan that can steal data and also load other malware. Emotet thrives on unsophisticated password: a reminder of the importance of creating a secure password to guard against cyber threats.

End-user protection

End-user protection or endpoint security is a crucial aspect of cyber security. After all, it is often an individual (the end-user) who accidentally uploads malware or another form of cyber threat to their desktop, laptop or mobile device.

So, how do cyber-security measures protect end users and systems? First, cyber-security relies on cryptographic protocols to encrypt emails, files, and other critical data. This not only protects information in transit, but also guards against loss or theft.

In addition, end-user security software scans computers for pieces of malicious code, quarantines this code, and then removes it from the machine. Security programs can even detect and remove malicious code hidden in Master Boot Record (MBR) and are designed to encrypt or wipe data from computer’s hard drive.

Electronic security protocols also focus on real-time malware detection. Many use heuristic and behavioral analysis to monitor the behavior of a program and its code to defend against viruses or Trojans that change their shape with each execution (polymorphic and metamorphic malware). Security programs can confine potentially malicious programs to a virtual bubble separate from a user’s network to analyze their behavior and learn how to better detect new infections.

Security programs continue to evolve new defenses as cyber-security professionals identify new threats and new ways to combat them. To make the most of end-user security software, employees need to be educated about how to use it. Crucially, keeping it running and updating it frequently ensures that it can protect users against the latest cyber threats.

Cyber safety tips – protect yourself against cyber attacks

How can businesses and individuals guard against cyber threats? Here are our top cyber safety tips:

  1. Update your software and operating system: This means you benefit from the latest security patches.
  2. Use anti-virus software: Security solutions will detect and removes threats. Keep your software updated for the best level of protection.
  3. Use strong passwords: Ensure your passwords are not easily guessable.
  4. Do not open email attachments from unknown senders: These could be infected with malware.
  5. Do not click on links in emails from unknown senders or unfamiliar websites:This is a common way that malware is spread.
  6. Avoid using unsecure WiFi networks in public places: Unsecure networks leave you vulnerable to man-in-the-middle attacks.

What is Firewall? A Firewall is a network security device that monitors and filters incoming and outgoing network traffic based on an organization's previously established security policies. At its most basic, a firewall is essentially the barrier that sits between a private internal network and the public Internet.

 

Secure your network at the gateway against threats such as intrusions, Viruses, Spyware, Worms, Trojans, Adware, Keyloggers, Malicious Mobile Code (MMC), and other dangerous applications for total protection in a convenient, affordable subscription-based service. Modern threats like web-based malware attacks, targeted attacks, application-layer attacks, and more have had a significantly negative effect on the threat landscape. In fact, more than 80% of all new malware and intrusion attempts are exploiting weaknesses in applications, as opposed to weaknesses in networking components and services. Stateful firewalls with simple packet filtering capabilities were efficient blocking unwanted applications as most applications met the port-protocol expectations. Administrators could promptly prevent an unsafe application from being accessed by users by blocking the associated ports and protocols.
