A recent security breach of the T-Mobile network has resulted in two issues: the loss of confidential data and the risk of SIM hijacking.

Data breaches are commonplace in the world of hacking, but SIM hijacking is less familiar outside of the telecoms industry. SIM cards, of course, are used in mobile phones to identify users to networks and allow them to make calls. These SIM cards are highly secure given the amount of data they contain and the finances associated with them e.g. contracts. And mobile phones are now a crucial part of any modern business for communications to run smoothly. Accordingly, protecting SIM cards for organizations should be a major concern.

But what is SIM hijacking? And what can you do to protect your SIM cards?

The T-Mobile Breach

In what is the fourth such attack in 18 months, around 48 million customers – many of them former customers – have been affected by the latest T-Mobile breach. Quickly Check If You’re Email Was BreachedThe cause of this breach has not, as of yet, been identified, but the data in question has. Stolen data includes:

  • Names
  • Social security numbers
  • Birthdates
  • Driver’s license details

Around 850,000 customers who hold pre-paid accounts have also had their names, phone numbers and account PINs stolen. All of this data is currently being sold online and represents a major security threat to those involved. And, for those whose number has been exposed, there is also the very real risk of falling victim to SIM hijacking.

What is SIM Hijacking?

SIM hijacking is a process where a hacker attempts to obtain control over a mobile phone account by moving the associated number to a new device. This is achieved by contacting a service provider – such as T-Mobile – and adopting a false identity. You may wonder why people want to steal a mobile number. After all, having access to a set of phone numbers isn’t overly exciting for a hacker. But we live in a world where mobile phones are regularly used for two-factor authorization. Therefore, having access to a phone number can open all manner of opportunities to a hacker.

How Do You Prevent SIM Hijacking?

Once a hacker has your phone number there is little you can do to stop them attempting to hijack your SIM. Naturally, the simplest option is to limit the number of times you give out your mobile number. But this is difficult when we live in an age when so many companies request your number for contact purposes. Nonetheless, it is possible to limit the damage by carrying out the following:

  • Certain service providers such as T-Mobile and Verizon offer security features which block SIM swaps by either requesting a security PIN or using the existing device to authorize the swap

The Dangerous Power of the Prometheus Malware

Malware-as-a-service (MaaS) provides a powerful malware solution for hackers. And Prometheus is the perfect example of such an infrastructure.

There’s money in everything and hacking is no different. But rather than extorting funds through ransomware, hackers can also design MaaS to generate some quick cash. MaaS takes the pain out of designing your own malware by offering a ready-made solution. And all you need to do is a pay a fee to use it. Typically, MaaS will give the user access to software which can distribute malware through malicious campaigns; this is exactly what Prometheus does.

As Prometheus, and all forms of MaaS, is so powerful, it’s important that you understand what it is and how to tackle it.

How Does Prometheus Work?

Prometheus has been available to purchase for a year now, with a subscription costing $250 per month. It uses two main attack strategies:

  • Distributing MS Word and Excel documents which are infected with malware
  • Using malicious links to divert victims to phishing websites

Subscribers to the Prometheus MaaS are given a central control panel from where they can launch their campaigns. From here they are able to configure various parameters to tailor their attacks e.g. targeting specific email addresses with a malicious call-to-action. Prometheus can also be used to assess potential victims. Using infected websites, Prometheus can collect data on visitors – such as IP address and user details – to assess which method of attack is best to launch. It’s a sophisticated form of hacking and one that requires high levels of awareness to combat.

It’s estimated that over 3,000 email addresses have been targeted by Prometheus as of this writing. These targets have included individuals in Europe and a number of government agencies and businesses in the US. While 3,000 potential victims may sound relatively small, it’s clearly best for every one of them to avoid it. And it is possible.

How to Combat Prometheus

Prometheus uses traditional methods to infect PCs with its malicious payloads, so it’s easy to avoid becoming a victim. All you need to do is practice the following:

  • Check All Emails: Malicious emails are very good at hiding the fact that they are malicious. Therefore, it always pays to quickly verify every email. Is the email address correct or is it a strange variation e.g. security@micros0ft.com? Is there an unusual and urgent call-to-action in the email such as a “click here before you lose access to your account” link? Anything suspicious should be queried with your IT team immediately.
  • Verify Links: It’s very easy to insert a malicious link into an email or website, so these need to be verified before clicking. For example, a link could be displayed as www.bankofamerica.com but hovering your cursor over this link will reveal the genuine destination. And this could be redirecting you towards a malicious website, so always verify your links.

5 Best Tips to Make Remote Working on a PC a Success

Remote working is becoming an increasingly popular way for organizations and their staff to operate. But it’s crucial that you know how to do it properly.

The popularity of remote working has been growing for several years, but this growth has been accelerated by the Covid-19 pandemic. Working from remote locations, however, doesn’t come without challenges. A home, for example, wasn’t built to be used as a workplace. And it’s unlikely that a home will come pre-loaded with powerful communication options. But challenges such as these can easily be tackled.

All you have to do is take a look at our 5 best tips to make remote working on a PC a success.

Enhancing the Remote Working Experience

Simplicity is an essential part of any infrastructure and remote working is no different. Therefore, make sure you integrate these simple tips into your remote working setup:

  1. Comfort is Key: It’s important that you create a suitable working space for setting up your PC. A quiet location with minimal distractions is vital, so it’s a good idea to set up in a location away from TVs and any other noise sources. The most pressing element, however, is a good chair. You’re going to be sitting in the same seat for several hours a day, so you need to get one which is both comfortable and suitable.
  2. Collaboration Tools: Communicating while remote working is very different to communicating when all employees are based in a central location. Naturally, this can lead to an increase in the time taken to answer queries, but it’s easy to work around this. Software such as Microsoft Teams, Discord and Slack allows employees to communicate and collaborate with ease.
  3. Invest in Your Equipment: Whether you’re using your own PC or a work issued one, it pays to invest in your technology. It may be as simple as upgrading your internet connection to increase connection speeds and reliability. Alternatively, you may wish to invest in replacement peripherals which are more ergonomic such as mice, keyboards and headphones.
  4. Use Calendar Apps: Without a team around you, it’s difficult for you to keep on top of things. After all, an office full of employees can quickly remind you that you have a meeting coming up. But a remote worker doesn’t have this luxury. Therefore, using calendar apps such as Google Calendar and Microsoft Calendar can prove invaluable. Take time each week to set up important reminders in these to ensure you remain on top of your schedule.
  5. Don’t Ignore Technical Issues: One of the drawbacks of remote working is that a technical issue can quickly disrupt your day. The luxury of jumping on a spare workstation isn’t an issue when you’re away from the office. And this is why it’s crucial that you report all technical issues to your IT team as soon as possible. An early investigation could easily prevent a major technical fault and allow you to stay productive.

What Do You Need in Good Antivirus Software?

Jul 2021

Antivirus software is a sure-fire way to keep your PC protected against malware. But you need to make sure it has the right features for your organization.

No two pieces of antivirus software are the same. And there are a lot of different antivirus tools available. In fact, if you google the term “antivirus software” you will be faced with 175 million search results. Not surprisingly, the sheer range of options available can make choosing one a daunting task. But it doesn’t need to be this difficult. All you need to do is understand what the most important features are in antivirus software.

The Essential Antivirus Software Features

As I advised earlier, there are many different antivirus tools trying to get your attention. And they all contain a collection of different features. The most essential ones that you should be looking for are:

  • Firewall Availability: Many antivirus software packages will include a firewall and this feature can prove invaluable. It’s a tool which is employed to monitor all incoming and outgoing connections to your network. Essentially a barrier between your organization and the internet, a firewall allows you to restrict access to any unidentified connections while recognized and permitted connections can operate freely.
  • Email Scans: One of the best ways for a hacker to gain access to your organization’s network is via email. It’s a venture which typically succeeds when an infected email attachment or malicious link is activated by the recipient. And these infections can be very powerful. Ransomware is easily spread through malicious emails and phishing scams, of course, are particularly prevalent. Thankfully, many pieces of antivirus software can scan all incoming emails to evaluate the danger contained within.
  • Download Protection: Most files that you download from the internet will be fine e.g. software installation packages or even plain old spreadsheets. But there’s always a chance that you may download some malicious software. And, in many cases, it’s easy to find yourself fooled by authentic looking websites. A good antivirus suite, however, should be able to scan all downloaded files in real time to verify if they are safe. Often, if the file is hosted on a malicious website, antivirus software will not even allow you access to the site in the first place.

Final Thoughts

Basic antivirus software is available for free and, despite some limitations in its functionality, can provide you with powerful protection. However, when you start paying for antivirus software you can expect to gain even more features and some much-needed technical support. Regardless of which option you go for, though, antivirus software should be an essential part of any organization’s fight against cyber-crime.
