What Are Tailgating Attacks and How to Protect Yourself From Them

By McAfee

Whether you’re spending time on the web or working in the office, you want peace of mind knowing that you are in a safe environment. While most of us know to take precautions when online — protecting ourselves from things like phishing attacks and other cyber threats — we should also attend to our physical security. 

One concern is tailgating — a social engineering attack where someone gets physical access to a business to take confidential information or do other harm. 

Here are some ways to protect yourself from tailgating attacks, such as an unauthorized person following you into a restricted area while on the job. 

What is a tailgating attack?

Tailgating is a type of social engineering attack where an unauthorized person gains physical access to an off-limits location — perhaps a password-protected area — where they might steal sensitive information, damage property, compromise user credentials or even install malware on computers. 

Piggybacking” is closely related to tailgating, but it involves consent from the duped employee. So, while a worker might be unaware that someone has tailgated them into a restricted area with piggybacking, the hacker might convince a worker to provide access because they are posing as, say, a delivery driver. 

Who’s at risk of tailgating attacks?

Companies, particularly at risk of being targeted by tailgating scams, include those: 

  • With many employees, often moving inside and out of the premises 
  • With multiple entrance points into a building 
  • That receive deliveries of food, packages, documents, and other things regularly 
  • That have many subcontractors working for them 
  • Where employees aren’t thoroughly trained in physical and cybersecurity protocols 

Generally speaking, companies with robust security systems in place — including using biometrics, badges, or other identity and information security measures — are better protected from tailgating and piggybacking attacks.  

But that’s not to say that some smooth-talking fraudster can’t talk someone into letting them in or finding some way around those protections. 

What are common tailgating methods?

Common types of tailgating attacks that you should be aware of on the job include:  

  • Someone walking behind you into a secure area, depending on your common courtesy to keep the door open for them 
  • A courier or delivery driver who aren’t what they seem 
  • Someone with their hands full of items to trick you into opening the door for them 
  • A person who claims they’ve lost their work ID or forgotten it at home, so that you grant them admittance 

How to protect yourself from tailgating attacks 

Protecting yourself from tailgating attacks is partly a matter of learning about the issue, raising your level of awareness on the job, and depending on your employer, putting in place more effective security systems.  

Some solutions include: 

Increased security training

Many companies know how to train employees to recognize, avoid, and cope with online security issues but may forget to provide the same diligence to physical security. How to spot and deal with threats should be part of this training, plus cultivating an awareness of surroundings and people who might be out of place.   

Management should offer a clearly stated security policy taught to everyone, which might insist that no one be allowed into a secure area without the proper pass or identification. As the security policy is updated, all employees should be aware of changes and additions. 

These security measures should be part of an overall protection program, like McAfee+, which includes antivirus software, a firewall, identity monitoring, password management, web protection, and more. 

Smart badges and cards

If you have a large business spread over several floors, it can be hard for employees to know who works there and who doesn’t, leaving them susceptible to tailgating and piggybacking attacks. Requiring smart badges and cards to access restricted areas can help cut back on unauthorized intrusions and provide better access control. 

Building fully staffed reception areas with dedicated security personnel could also be part of a larger security system. 

Biometric scanners

Biometric scanners are an even more advanced way to provide proper authentication for a worker’s identity. They scan a unique physical or audible feature of a person and compare it to a database for approved personnel.  

Examples of biometric security include: 

  • Voice recognition 
  • Iris recognition 
  • Fingerprint scans 
  • Facial recognition 
  • Heart-rate sensors 

Understanding social engineering

One reason people are vulnerable to physical and cyberattacks is that they lack education on social engineering and the kinds of threats it poses.  

Workers need to understand the full range of social engineering techniques and know-how to protect themselves, whether in their social media accounts or physical work environment.  

For their part, companies can use simulated phishing emails and tailgating attacks to raise awareness and underline how to follow protocols in dealing with them. 

Video surveillance

If there are many ways to enter a business, it may make sense to put video surveillance on all entrances. Advanced video surveillance systems can use artificial intelligence (AI) and video analytics to scan the faces of people entering and compare them to a database of employee features. 

Discover how McAfee can help keep devices secure from hacking

Whether at work or at home, people want to be secure from attacks by cybercriminals who seek to take personal information. 

To add a layer of security to all their connected devices — including computers, smartphones, and tablets — an increasing number of people are turning to the comprehensive coverage of McAfee+ 

Features range from advanced monitoring of possible threats to your identity, automatic implementation of virtual private networks (VPNs) to deal with unsafe networks, and personal data clean-up, removing your information from high-risk data broker sites.

Cybercrime’s Most Wanted: Four Mobile Threats that Might Surprise You

By McAfee

It’s hard to imagine a world without cellphones. Whether it be a smartphone or a flip phone, these devices have truly shaped the late 20th century and will continue to do so for the foreseeable future. But while users have become accustomed to having almost everything they could ever want at fingertips length, cybercriminals were busy setting up shop. To trick unsuspecting users, cybercriminals have set up crafty mobile threats – some that users may not even be fully aware of. These sneaky cyberthreats include SMSishing, fake networks, malicious apps, and grayware, which have all grown in sophistication over time. This means users need to be equipped with the know-how to navigate the choppy waters that come with these smartphone-related cyberthreats. Let’s get started.

Watch out for SMSishing Hooks

If you use email, then you are probably familiar with what phishing is. And while phishing is commonly executed through email and malicious links, there is a form of phishing that specifically targets mobile devices called SMSishing. This growing threat allows cybercriminals to utilize messaging apps to send unsuspecting users a SMSishing message. These messages serve one purpose – to obtain personal information, such as logins and financial information. With that information, cybercriminals could impersonate the user to access banking records or steal their identity.

While this threat was once a rarity, it’s rise in popularity is two-fold. The first aspect being that users have been educated to distrust email messages and the second being the rise in mobile phone usage throughout the world. Although this threat shows no sign of slowing down, there are ways to avoid a cybercriminal’s SMSishing hooks. Get started with these tips:

  1. Always double-check the message’s source. If you receive a text from your bank or credit card company, call the organization directly to ensure the message is legit.
  2. Delete potential SMSishing Do not reply to or click on any links within a suspected malicious text, as that could lead to more SMSishing attempts bombarding your phone.
  3. Invest in comprehensive mobile security. Adding an extra level of security can not only help protect your device but can also notify you when a threat arises.

Public Wi-Fi Woes  

Public and free Wi-Fi is practically everywhere nowadays, with some destinations even having city-wide Wi-Fi set up. But that Wi-Fi users are connecting their mobile device to may not be the most secure, given cybercriminals can exploit weaknesses in these networks to intercept messages, login credentials, or other personal information. Beyond exploiting weaknesses, some cybercriminals take it a step further and create fake networks with generic names that trick unsuspecting users into connecting their devices. These networks are called “evil-twin” networks. For help in spotting these imposters, there are few tricks the savvy user can deploy to prevent an evil twin network from wreaking havoc on their mobile device:

  1. Look for password-protected networks. As strange as it sounds, if you purposely enter the incorrect password but are still allowed access, the network is most likely a fraud.
  2. Pay attention to page load times. If the network you are using is very slow, it is more likely a cybercriminal is using an unreliable mobile hotspot to connect your mobile device to the web.
  3. Use a virtual private network or VPN. While you’re on-the-go and using public Wi-Fi, add an extra layer of security in the event you accidentally connect to a malicious network. VPNs can encrypt your online activity and keep it away from prying eyes. 

Malicious Apps: Fake It till They Make It

Fake apps have become a rampant problem for Android and iPhone users alike. This is mainly in part due to malicious apps hiding in plain sight on legitimate sources, such as the Google Play Store and Apple’s App Store. After users download a faulty app, cybercriminals deploy malware that operates in the background of mobile devices which makes it difficult for users to realize anything is wrong. And while users think they’ve just downloaded another run-of-the-mill app, the malware is hard at work obtaining personal data.

In order to keep sensitive information out of the hands of cybercriminals, here are a few things users can look for when they need to determine whether an app is fact or fiction:

  1. Check for typos and poor grammar. Always check the app developer name, product title, and description for typos and grammatical errors. Often, malicious developers will spoof real developer IDs, even just by a single letter or number, to seem legitimate.
  2. Examine the download statistics. If you’re attempting to download a popular app, but it has a surprisingly low number of downloads, that is a good indicator that an app is most likely fake.
  3. Read the reviews. With malicious apps, user reviews are your friend. By reading a few, you can receive vital information that can help you determine whether the app is fake or not.

The Sly Operation of Grayware

With so many types of malware out in the world, it’s hard to keep track of them all. But there is one in particular that mobile device users need to be keenly aware of called grayware. As a coverall term for software or code that sits between normal and malicious, grayware comes in many forms, such as adware, spyware or madware. While adware and spyware can sometimes operate simultaneously on infected computers, madware — or adware on mobile devices — infiltrates smartphones by hiding within rogue apps. Once a mobile device is infected with madware from a malicious app, ads can infiltrate almost every aspect on a user’s phone. Madware isn’t just annoying; it also is a security and privacy risk, as some threats will try to obtain users’ data. To avoid the annoyance, as well as the cybersecurity risks of grayware, users can prepare their devices with these cautionary steps:

  1. Be sure to update your device. Grayware looks for vulnerabilities that can be exploited, so be sure to always keep your device’s software up-to-date.
  2. Beware of rogue apps. As mentioned in the previous section, fake apps are now a part of owning a smartphone. Use the tips in the above section to ensure you keep malicious apps off of your device that may contain grayware.
  3. Consider a comprehensive mobile security system. By adding an extra level of security, you can help protect your devices from threats, both old and new.

Cybersecurity Considerations in the Work-From-Home Era

By Yong Kim
Cyberthreat keywords

Note: This article originally appeared in Verisign’s Q3 2020 Domain Name Industry Brief.

Verisign is deeply committed to protecting our critical internet infrastructure from potential cybersecurity threats, and to keeping up to date on the changing cyber landscape. 

Over the years, cybercriminals have grown more sophisticated, adapting to changing business practices and diversifying their approaches in non-traditional ways. We have seen security threats continue to evolve in 2020, as many businesses have shifted to a work from home posture due to the COVID-19 pandemic. For example, the phenomenon of “Zoom-bombing” video meetings and online learning sessions had not been a widespread issue until, suddenly, it became one. 

As more people began accessing company applications and files over their home networks, IT departments implemented new tools and set new policies to find the right balance between protecting company assets and sensitive information, and enabling employees to be just as productive at home as they would be in the office. Even the exponential jump in the use of home-networked printers that might or might not be properly secured represented a new security consideration for some corporate IT teams. 

An increase in phishing scams accompanied this shift in working patterns. About a month after much of the global workforce began working from home in greater numbers, the Federal Bureau of Investigation (FBI) reported about a 300 percent to 400 percent spike in cybersecurity complaints received by its Internet Crime Complaint Center (IC3) each day. According to the International Criminal Police Organization (Interpol), “[o]f global cyber-scams, 59% are coming in the form of spear phishing.” These phishing campaigns targeted an array of sectors, such as healthcare and government agencies, by imitating health experts or COVID-related charities.

Proactive steps can help businesses improve their cybersecurity hygiene and guard against phishing scams. One of these steps is for companies to focus part of their efforts on educating employees on how to detect and avoid malicious websites in phishing emails. Companies can start by building employee understanding of how to identify the destination domain of a URL (Uniform Resource Locator – commonly referring to as “links”) embedded in an email that may be malicious. URLs can be complex and confusing and cybercriminals, who are well aware of that complexity, often use deceptive tactics within the URLs to mask the malicious destination domain. Companies can take proactive steps to inform their employees of these deceptive tactics and help them avoid malicious websites. Some of the most common tactics are described in Table 1 below.

Tactic What is it?
Combosquatting Adding words such as “secure,” “login” or “account” to a familiar domain name to trick users into thinking it is affiliated with the known domain name.
Typosquatting Using domain names that resemble a familiar name but incorporate common typographical mistakes, such as reversing letters or leaving out or adding a character.
Levelsquatting Using familiar names/domain names as part of a subdomain within a URL, making it difficult to discover the real destination domain.
Homograph attacks Using homograph, or lookalike, domain names, such as substituting the uppercase “I” or number “1” where a lowercase “L” should have been used, or using “é” instead of an “e.”
Misplaced domain Planting familiar domain names within the URL as a way of adding a familiar domain name into a complex-looking URL. The familiar domain name could be found in a path (after a “/”), as part of the additional parameters (after a “?”), as an anchor/fragment identifier (after a “#”) or in the HTTP credentials (before “@”).
URL-encoded characters Placing URL-encoded characters (%[code]), which are sometimes used in URL parameters, into the domain name itself.
Table 1. Common tactics used by cybercriminals to mask the destination domain.

Teaching users to find and understand the domain portion of the URL can have lasting and positive effects on an organization’s ability to avoid phishing links. By providing employees (and their families) with this basic information, companies can better protect themselves against cybersecurity issues such as compromised networks, financial losses and data breaches.

1H 2020 Cyber Security Defined by Covid-19 Pandemic

By Jon Clay (Global Threat Communications)

When we published our 2020 Predictions report in December, we didn’t realize there was a global pandemic brewing that would give cybercriminals an almost daily news cycle to take advantage of in their attacks against people and organizations around the world. Malicious actors have always taken advantage of big news to use as lures for socially engineered threats, but these events tend to be fairly short news cycles.

When Covid-19 started making headlines in early 2020, we started seeing new threats using this in the attacks. As you see below, April was the peak month for email-based Covid-19 related threats.

The same was true for phishing URLs related to Covid-19, but for files using Covid-19 in their naming convention, the peak month in the first half was June.

Impact on Cybercrime

The constant 24×7 news around cases, cures and vaccines makes this pandemic unique for cybercriminals. Also, the shift to remote working and the challenges posed to supply chains all gave cybercriminals new content they could use as lures to entice victims into infecting themselves.

As we’ve seen for many years now, email-based threats were the most used threat vector by malicious actors, which makes sense as the number one infection vector to penetrate an organization’s network is to use a socially engineered email against an employee.

We even saw malicious mobile apps being developed using Covid-19 as a lure, as you see below.

In this case it was supporting potential cures for the virus, which many people would have wanted.

Other Highlights in 1H 2020

While Covid-19 dominated the threat landscape in the 1H 2020, it wasn’t the only thing that defined it. Ransomware actors continued their attacks against organizations, but as we’ve been seeing over the past year, they’ve become much more selective in their victims. The spray and pray model using spam has been shifted to a more targeted approach, similar to how nation-state actors and APT groups perform their attacks. Two things showcase this trend:

  1. The number of ransomware detections has dropped significantly from 1H 2019 to 1H 2020, showing that ransomware actors are not looking for broad infection numbers.
  2. The ransom amounts have increased significantly over the years, showing ransomware actors are selecting their victims around how much they feel they can extort them for and whether they are more likely to pay a ransom.

Home network attacks are another interesting aspect of the threat landscape in the first half of this year. We have millions of home routers around the world that give us threat data on events coming into and out of home networks.

Threat actors are taking advantage of more remote workers by launching more attacks against these home networks. As you see below, the first half of 2020 saw a marked increase in attacks.

Many of these attacks are brute force login attempts as actors try to obtain login credentials for routers and devices within the home network, which can allow them to do further damage.

The above are only a small number of security events and trends we saw in just six months of 2020. Our full roundup of the security landscape so far this year is detailed out in our security roundup report – Securing the Pandemic-Disrupted Workplace. You can read about all we found to help prepare for many of the threats we will continue to see for the rest of the year.
