As work from home is the new norm in the COVID-19 era, you’re probably looking to enable remote desktop connections for your off-site staff. Here’s how to do it securely.

Undoubtedly, having remote access to your workstations’ or servers can enable better management, right? However, with the current upsurge of hackers, such can be a pipeline dream. A small security breach, such as the access of your administrator’s login to your domain controller, can lead to massive losses of resources.

For instance, the loss of your company’s intellectual property, the encryption of your files for ransom purposes, or loss of huge amounts of money through dubious corporate emails send to your accounting department and books.

In this post, we look at the different ways you can restrict your RDP to defend it against (all remote access software such as PC Anywhere, VNC and Teamviewer, among others, as well as Microsoft’s RDP) attacks. Here we go!

Limit access to your resources

By allowing access only from internal addresses coming from your company’s VPN server helps in preventing the exposure of your RDP connection ports to the public internet. By doing so, you will reduce the chances of your RDP being attacked.

Nevertheless, if exposing your ports is the only way out, you can serve your RDP on a non-standard port number to protect it against simplistic worms that can attack your network through its ports. 

On the flip side, this method can’t protect your RDP from sophisticated attackers as a majority of network scanners check all ports for RDP activity.

Consequently, you will be forced to stay on constant alert regarding any login activities or network access in your RDP server logs, since an attacker can strike at any time.

Utilize Multi-Factor Authentication (MFA)

Another way to secure your RDP is to ensure that your remote workers are utilizing another authentication layer (MFA), as we have discussed in this post.

Whitelist allowed IP addresses

To create a list of allowable addresses that will have access to your workstations, you can instruct your employees to look up for their IP addresses and surrender them to your IT personnel. With this list, you can have control over your resources, for instance, who can access them or not.

Alternatively, you can build a whitelist of allowable IP’s by enabling their subnet, since dynamic home IP addresses would typically fall within a subnet after a router reboot or other network maintenance on the client end.

Final thoughts

Off late, there is an increasing trend regarding RDP attacks; therefore, it is essential to ensure that yours is patched to the current security level to avoid issues.

The scam machine shows no signs of slowing down, as fraudsters continue to dispense bogus health advice, peddle fake testing kits and issue malware-laced purchase orders

As the Coronavirus pandemic continues to escalate, more companies are now shifting to remote work as a way of containing the spread of the disease. Similarly, lockdowns and travel bans, among other stringent measures, have become the order of the day across several nations. And to worsen the situation, there is a massive shortage of the required medical kits.

Such a crisis provides fraudsters undue advantage over a vulnerable lot that is financially destabilized, as well as emotionally drained as a result of the pandemic. 

In this case, you would likely receive fake updates regarding the pandemic, as well as non-existent offers for personal protective equipment, among others. Likewise, if you’re a business, you would certainly receive faux purchase orders and payment information.

Fortunately, as a follow up to our previous article about the ways scammers are exploiting coronavirus fears, we provide you with a few examples of the new campaigns aimed at stealing your money or personal information. To enable you to keep your guard up. Shall we?

Fake news/information

As the virus continues to escalate, more people are currently searching for practical information on how they can protect themselves. As a result, scammers have conveniently positioned themselves as the true COVID-19 information “crusaders” by impersonating well-known health organizations, such as the World health organization.

Don’t act surprised if you receive an email (containing an attachment) supposedly coming from a reputable health organization offering you “vital information” on how you can protect yourself from the disease.

For instance, our research team identified one such file containing a Trojan designed to steal personal credentials.

Apart from the WHO, fraudsters are also impersonating the US Centers for Disease Control and Prevention (CDC). Accordingly, the FBI has given a warning about scummy emails mainly riddled with malware-infested attachments and links purporting to originate from the CDC.

 To reduce the number of people falling for such schemes, the WHO shares examples of its official email addresses and methods of communication on its website.

Urgent purchase orders and late payments

Owing to the increased pressure from governments to reduce the spread of the virus, Companies, as well as factories, have been forced to streamline their operations according to the current situation. As an example, companies to integrate work from home modules, while factories to either increase or reduce their production capacities depending on their products.

Such erratic changes have brought about a climate of uncertainty that offers fraudsters a thriving environment.

In this case, as a factory owner or executive, be on the lookout for “urgent purchase orders” from “company representatives.” Since this fake orders come from scammers who want to make a kill out of your desperation of making some revenue before things go south.

Sadly, if you download such “urgent orders” (usually in attachments), your PC will be installed with malicious code designed to steal your details.

Below is an excellent example of such an “urgent order”:

Similarly, you would receive a “proof of payment” for you to take care of the order. However, like the last example above, instead of receiving a bank statement, the attached document contains a Trojan injector.

High demand products

A massive increase in demand compounded with an inadequate supply for essential protective items, such face masks has created another avenue for scams.

A typical example of such a scam involves a fraudulent site that is offering “OxyBreath Pro” face masks at a reduced price. These can lure you since there is a shortage of masks, and what is available is highly-priced.

However, if you click on the provided links, you’ll be at risk of exposing your sensitive personal information to the scammers.

Bogus testing gear

The unavailability or short supply of medical kits for testing folks for the virus has also attracted fraudsters in droves.

For instance, the existent low supply of masks, respirators, and hand sanitizers, among other necessities, has prompted scammers to impersonate medical officials.  So that, they can provide non-existent or fake COVID-19 test kits, as well as illegitimate “corona cures.”

As an illustration, more than 2000, links associated with fake coronavirus products have already been identified. Similarly, law enforcement bureaus alongside other relevant bodies have been able to seize US$ 13 million worth of potentially hazardous pharmaceuticals.

To contain these despicable actions, the U.S. Food and Drug Administration (FDA) has issued warnings that it hasn’t allowed the sale or purchase of coronavirus self-testing kits; therefore, it is currently bursting such sellers.

Final thoughts

In a wrap, what we have shared is a representative of the many current fraudulent campaigns doing rounds in our media spaces due to the prevailing situation.

Thus, it is critical to maintaining high alertness to avoid falling victim to both the COVID-19 pandemic, as well as the ensuing scam epidemic escalating through the internet. To keep yourself safe from the scams, you can practice the following basics:

  1. Avoid downloading files or clicking on links from unknown sources
  2. Never fall for unrealistic offers or order goods from unverified suppliers. You may also make a point of checking out the purported vendor’s reviews
  3. Invest in an excellent endpoint solution which can shield you from phishing attacks, as well as other forms of scams
  4. If an email suggests coming from a reputable organization, double-check with the firm’s website to confirm its authenticity

If you require consultation, as well as endpoint solutions for your cybersecurity needs, then ESET has been here for you for over 30 years. We want to assure you that we will be here to protect your online activities during these uncertain times, too.

How To Easily Set Up a VPN at Home 0 995

As the COVID-19 pandemic has many organizations switching employees to remote work, a virtual private network is essential for countering the increased security risks

Probably, you have been forced to work from home due to the COVID-19 outbreak (recommended to reduce the spread of the virus). However, you are wondering how you will set up your VPN to enable secure communication.

Well, don’t agonize too much; we shall first explain to you what a VPN entails. And then, provide you with a step by step procedure for setting a basic Virtual Private Network. Here we go!

First, what is a Virtual Private Network (VPN)?

Essentially, a VPN is a private channel within a wider (open) network that enables you to communicate with your peers (other nodes with similar settings) without leaking your information through the use of encryption.

Besides, you can utilize a VPN to initiate communication through any network without revealing your location. In any case, a significant number of vendors deal with clients needing such services to avoid being tracked or be able to bypass particular network filters. 

However, in our case, we shall consider a home office VPN that will create a communication tunnel for your practical and secure home office communication.

Is it necessary to set up a virtual private network?

For there to be any communication between two endpoints ─ your pc and the computer in the main office –, they must be configured.

In this case, you’ll require the services of your IT department (if you have one), who will guide you regarding the applications to install, as well as provide you with VPN credentials depending on your needs. Upon installing and configuring the said app, you can automatically establish communication through the provided link. Easy-peasy, right?

On the other hand, if you don’t have an IT department behind your back, then you may have to do it yourself. These shouldn’t; however, scare you at all; it’s not as tough as you might imagine.

But before we explore the nitty-gritty of setting up the VPN, we first need to identify the options we have. In our case, we shall examine two options:

  • Open VPN: standard in small office/home office and business-class routers
  • IP Sec: Is Built-in and commonly used by desktops, smartphones, and laptops

The Open Virtual Private Network

This type of VPN has been around for a long time and has proved itself secure and reliable. It is ideal for small office/ house offices, as well as business-class routers, thanks to its open-source nature.

Procedure for installation

  1. On a contemporary device, go to the router’s configuration screen and click the relevant buttons to access your office network
  2. Download the configuration file generated by the router
  3. Use this file to configure/setup the OpenVPN in your pc, smartphone, or desktop that you want to use to access the Network behind that particular router. In case you get stuck somewhere, you can download or follow an online tutorial for your specific router.
  4. Download the required apps that will enable you to access your new home office VPN from this website.
  5. Install the downloaded applications and then configure them using the files generated when setting up the Open VPN on your office router.

In the event you find the going tough, you can always consult with an online tutorial or IT personnel.

Internet Protocol Security

IPsec is also another technology that has been in use for an extended period to provide reasonable security. It utilizes the same working principles as the OpenVPN; however, it is mostly used on lower-cost routers. Besides, it is a built-in technology in most desktops, laptops, and smartphones; therefore, it eliminates the need for installing another application on your device.

The installation process is similar to that one of OpenVPN. However, implementing a particular router IPsec can sometimes be a little more complicated compared to installing an open VPN.

Fortunately, with the use of native tools on your remote endpoints, you can offset this by just typing in a few things, such as the required IP address and credentials.

Final thoughts

Conclusively, these are some of the simplest virtual net protection options you can install on your home system without requiring massive/no input from IT experts.

Importantly, you will need a beefier than standard broadband for quick communication over the VPN. Also, you may experience slower connections due to the much horsepower required to keep the connection encrypted and tunneled. Nevertheless, this is a small price to pay in exchange for a secure home office communication.

In case you required any advice regarding VPN options or installation services, then ESET has been here for you for over 30 years. We want to assure you that we will be here to protect your online activities during these uncertain times, too.
