IT security can be a complex series of procedures and this can be intimidating to many people. Luckily, there are some easy ways to secure your PC.

Installing and configuring a firewall isn’t something that your average PC user will feel comfortable with. After all, how do you know exactly which services you should be allowing/denying access to? Security tasks such as this should be left to the professionals. But there are lots of quick and easy tips you can put in to place to protect your PC. All you need to do is know how to get started securing your PC. And today we’re going to share 5 quick ways to secure your PC.

How to Secure Your PC

If you want to secure your PC with the minimum amount of fuss, then make sure you:

  • Verify All Downloads: It’s very easy to fall victim to a malicious email or website. These threats appear to be genuine methods of communication in order to encourage you clicking on their malicious payload. These payloads can take the form of malicious downloads disguised as links or ‘helpful’ apps. A quick way to avoid falling victim in these scenarios is to verify the true destination of links by hovering your mouse cursor over them. You can also perform a Google search to verify the legitimacy of any website.
  • Do Not Write Your Passwords Down: The single biggest mistake that a PC user can make is to write their passwords down. Sure, it’s difficult to remember every single password, but there are options to overcome this such as using Google’s Password Checkup. These password managers are far superior to writing your password credentials on a Post-It note and keeping it on your desk. Revealing your login credentials publicly should be avoided at all costs.
  • Only Use USB Devices That You Own: It’s not worth the risk of damaging your PC, so avoid connecting USB devices you aren’t familiar with. In fact, in a workplace, it’s recommended to disable USB access to individual workstations. If USB access is required then this should only be granted to IT professionals.

The Dangers of SIM Hijacking

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

What Do You Need in Good Antivirus Software?

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.

Database of 26 Million Stolen Passwords Discovered

Passwords are one of the most common security measures, but they’re still considered a risk. And 26 million stolen passwords have just been found.

We all use passwords on a regular basis throughout our working day. Logging on to remote servers and online platforms all require a set of login credentials. And, on the whole, they provide an adequate level of security. But security which is considered only adequate will always remain a tempting prospect to hackers. Login credentials will typically consist of only two pieces of information: username and password. Naturally, with only two data values required – which can be entered from any keyboard – login credentials represent some major security concerns.

That’s why the discovery of this database, containing 26 million sources of information, is considered a major alert.

What’s in the Database?

Coming in at a huge 1.2TB, the database – which was discovered by NordLocker – contains the following:

  • 26 million login credentials
  • 2 billion browser cookies
  • 1.1 million email addresses
  • 6.6 million various files including Word, PDF and image files

These numbers are, of course, huge. And it’s a safe bet that some serious data has been compromised along the way. It has also been revealed that the malware made a point of creating an image file by taking a screenshot via active webcams on infected devices. This, again, is troubling as it underlines the danger contained within the malware for compromising personal data.

The actual malware behind these data harvests is currently unknown. It is believed, however, that its method of attack is fairly standard. Upon infection, the malware will connect to a remote server where it can transmit any stolen data. The compromised data, as NordLocker found, was being hosted on a cloud-based hosting service and has now been taken down. But it’s likely that this database has already been traded and is out in the digital wild.

How Do You Protect Yourself?

Attacks such as this are sadly commonplace in the modern age, but there is a lot that you can do to protect your organization’s data:

  • Use Two-Factor Authentication: The combination of a username and password may seem strong, but it can be made even stronger by two-factor authentication. This additional layer of security requires the use of a unique piece of data transmitted to a device separate from your IT network.
  • Install All Updates: The attack in question could easily have been caused by a vulnerability put in place by outdated technology. Both software and hardware require regular updates to patch any issues that may be discovered post-launch. And it’s your responsibility to install these as soon as possible to close any potential back door attacks.
  • Regularly Monitor Network Activity: If significant amounts of data are being stolen and transmitted to a remote server, this activity will be associated with a rise in outgoing network activity. Therefore, it pays to keep a close eye on any spikes in traffic to minimize the impact of any breach.

We’re all used to dealing with insurance for both our personal and business needs, but did you know it was possible to arrange cyber security insurance?

2020 saw financial losses caused by cyber crime topping $1 trillion. Yes, you read that right, $1 trillion. This is a phenomenal figure and one which underlines the damage that cyber breaches can cause. Ransomware, as you would expect, is a major contributor to this figure of $1 trillion and confirms just how important cyber security is. However, no set of defenses are 100% perfect. Accordingly, it’s possible for any organization to suffer financial losses. And this is where cyber security insurance comes in.

To help you understand the benefits of cyber security insurance and how it works, we’re going to take a quick look at the subject.

What is Cyber Security Insurance?

The impact of a data breach can be catastrophic for a business. Not only is there the damage to your reputation, but there are also the financial effects. Ransomware, of course, can pose an immediate financial risk. And many organizations feel pressured into paying the ransom fees demanded by hackers. There’s also the major risk of hackers causing direct damage to your hardware which, in turn, may need replacing. Compounding the impact even further is the threat of legal action from customers who feel as though their data has not been protected effectively.

Clearly, a cyber attack can quickly become very costly for your business. And it won’t be covered by your general liability insurance. This is why cyber security insurance has been developed. It serves to protect your business by covering your organization’s liability for any cyber attacks. This insurance is available from a wide range of vendors and is similar to almost all other forms of insurance. Each policy, which can be tailored to your specific needs, is costed accordingly and then registered against your business.

The Benefits of Cyber Security

But what exactly are the benefits of cyber security? Let’s take a look:

  • Recover Ransomware Losses: The funds demanded by ransomware can be costly and, if paid, can put a serious dent in your finances. Thankfully, with cyber security insurance in place, you can recoup any ransom funds through your insurance vendor.
  • Help Notifying Customers: By law, an organization needs to contact all affected parties when a data breach occurs. The time and energy required to carry out such a communication can be expensive. But the cost behind this exercise can be negated when you have taken out cyber security insurance.
