Black Friday Cyber Monday – Stop … Look … Think! 0 2290

Phishing email

Customers are not the only ones feeling opportunistic with the great deals offered over the Black Friday/Cyber Monday period, cyber criminals are too. The large scale of SALE communications sent to users prompting customers to “Click Here” and receive the deal of lifetime (for example) has created limitless ways for cybercriminals to cash in on unsuspecting victims. These communications come in the form of emails, SMS’s and social media posts, all of which can be easily replicated by cyber criminals.

We consulted our tech expert Dennis Koome on how to stay safe when shopping online.

So what do you, the customer, need to do to stay safe?

Stop, Look and Think

How’s your internet security mindset?

– Have you ever looked at yourself up online to see what information is out there about you?

– Have you clicked in any links in emails or on websites offering discounts?

– When shopping online, do you check the security status of the website?

– Have you paid attention to or customized your twitter, Facebook, skype, email security settings?

– At home, do you have an external backup source for your computer?

 

Some Terminologies:

  1. Spam: Unsolicited bulk commercial email messages.
  2. Phishing: Refers to tricking individuals into disclosing sensitive personal information or taking a potentially dangerous action, such as opening an infected attachment or visiting a compromised web link using deception via email.
  3. Spear Phishing: Refers to a form of phishing where the attack specifically targets an individual or a group. Since the attacker has researched the target and crafted their attack accordingly, spear phishing attacks are more likely to succeed.
  4. Spoofing: Refers to tricking or deceiving you or your system. This is done by hiding the sender’s identity or faking the identity of another user. This may involve sending messages from a bogus email address of another user.

 

DO’s and DON’TS

DON’TS:

  1. Open any email attachments that end with: .exe, .scr, .bat, .com, or other executable files you do not recognize
  2. “unsubscribe” – it is easier to delete the e-mail than to deal with the security risks.
  3. Respond or reply to spam in any way. Use the delete button
  4. Ever click embedded links in messages without hovering your mouse over them first to check the URL.

Always:

  1. Check the email ‘From’ field to validate the sender. This ‘From’ address may be spoofed.
  2. Note that www.eset.com and www.support.eset.software.com are two different domains
  3. Check for so-called ‘double-extended’ scam attachments. A text file named ‘safe.txt’ is safe, but a file called ‘safe.txt.exe’ is not.

Tips for Password Security

  1. Keep your passwords private – never share a password with anyone else.
  2. Do not write down your passwords.
  3. Use passwords of at least eight (8) characters or more (longer is better).
  4. Use a combination of uppercase letters, lowercase letters, numbers, and special characters (for example: !, @, &, %, +) in all passwords.
  5. Avoid using people’s or pet’s names, or words found in the dictionary; it’s also best to avoid using key dates (birthdays, anniversaries, etc.). Substituting look-alike characters for letters or numbers is no longer sufficient (for example, Password” and “P@ssw0rd”).
  6. A strong password should look like a series of random characters.
  7. On the web, if you think your password may have been compromised, change it at once and then check your website accounts for misuse. At work, change your password at once, and then call your company’s IT Security help desk.

Be on Alert for any email that asks:

  1. Replying (including sending an “unsubscribe” answer)
  2. Clicking any hyperlinks in the message (and that includes “unsubscribe” link)
  3. Opening an attachment.
  4. Forwarding the email message to others.
  5. Offers to gain something of value.
  6. Requires urgent, immediate action to avoid a negative consequence or to mitigate a threat.
  7. Asks you to resolve an urgent problem.

Recommended

When online shopping, it is recommended to do so on your personal internet connection rather than on a public WiFi connection, especially when required to enter passwords, banking details and personal information.

It is also recommended to secure all of your devices with internet security, many of us forget about our phones or tablets when we think about security however these devices are still avenues of attack!

Secure Videoconferencing: The Basics 0 1027

With COVID-19 concerns canceling face-to-face meetings, be aware of the security risks of videoconferencing and how to easily overcome them

As a way of controlling the spread of the COVID-19 pandemic, several countries have been forced to impose a lockdown on its citizens bringing normal operations to a near stand-still. Consequently, a considerable percentage of the working population has turned to remote working, a chunk of it for the first time.

This has spiked up the demand for video conferencing services, chat systems, and online collaboration tools to serve the increasing number of students, employees, and teachers, among other experts working from home.

By 11th March 2020, Kentik―a San Francisco network operator— had achieved a 200% increase in video traffic within the provided working hours in Asia and North America. Even before the start of the official lockdown in California.

In the same vein, the UK Prime Minister chaired a cabinet meeting via zoom, which communicated the government’s appeal for social distancing through the use of video conferencing. His actions, however, brought about several questions regarding the security of the communication.

But with a quick rejoinder, the UK’s National Cyber Security Centre pointed out that such communications shouldn’t cause any worries if they are below particular classifications. Accordingly, companies have developed confidence in the technology; therefore, are utilizing it to communicate with their remote workers.

Nevertheless, as an employee (or typical user), you need to understand the technology’s built-in security options, as well as control features before using it. Here we provide you with some primary considerations. Let’s dig in!

Your immediate surroundings

For you to realize a smooth and quality video conferencing experience, it is essential to cordon off your working space to prevent in kind of interruptions that might occur while in session; for instance, from your kids, better half, or even pets.

Besides, ensure that your working area is devoid of any sensitive or confidential information/material that can be captured by the camera.

Limit access

As you may be aware, a lot of video conferencing platforms allow the creation of multiple user groups to enable the providence of internet domain according to specific criteria; for instance, the use of company email address to join a video call.

Or offer access to a limited number of people whose email addresses have been invited or scheduled for a call.

As such, when creating a meeting, you can enable the set a meeting password option that creates a randomly generated code for your invitees to input before joining a conversation. Similarly, you can authenticate those using phones by the use of a numerical password. However, avoid embedding the password in the meeting link.

As an organizer, you can hold your participants in a “waiting room,” as you approve them one by one, which gives you full control over whom to allow or deny access. In case you have a large conference, you can delegate such duties to your trusted attendees.

File transfers and communication over the net

As a rule of thumb, always ensure that your end-to-end communication is encrypted. Do not assume that this option is the default for video calls since a few services may require you to request encryption.

If the third-party endpoint client software is permitted, ensure it abides by the requirements of the end-to-end encryption.

What’s more, consider limiting the types of documents you can send across the net; for instance, avoid transferring executable files.

Manage the attendees, as well as the engagement process

Often, your attendees will be distracted by notifications, pop-ups, and emails, among other things, when attending your conference calls. Therefore, as a host, you can request notification from your service provider if your conferencing client isn’t the primary or active window (depending on your platform). For instance, if you are a tutor, you can use this feature to get the attention of all your students.

You can also monitor those who joined the call by downloading the attendee list at the end of the call. Or request attendees to register before being connected.

Limit screen sharing capabilities

As the host, the sole responsibility of controlling screen sharing remains only yours, unless you delegate it to someone else that you trust. This eliminates any chances of an individual sharing content by mistake.

Importantly, only share the required application rather than the whole desktop when screen sharing. This is informed by the fact; even the name of a file or Icon can divulge sensitive company information.

Final thoughts

To ensure the security of your company communications, take time to consider all the available options security settings on your video conferencing system (or one you intend to use) settings. Importantly, take a look at the privacy policy of the service you intend to use to prevent the selling, sharing, collection, or re-use of your data.

Coronavirus con artists continue to thrive 0 965

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.
