Google’s Chrome is the most widely used browser on the internet, but this dominance also makes it a major target for hackers.

The popularity of Chrome means that it’s a vital asset for PC users and this applies to both domestic and business settings. One of the major advantages of Chrome is that it’s supported by a vast database of add-ons. These add-ons, which are coded by official developers or third-party coders, can be installed within seconds and provide an enhanced browsing experience. But the ease with which these add-ons can be released makes them a security risk.

This risk has been brought into sharp focus by a security lapse which has led to 32 million downloads of malicious spyware. And this startling figure is why we’re going to take a closer look at the situation.

What is a Chrome Add-on?

You may be wondering what a Chrome add-on is and it’s a good question which we will quickly cover. Add-ons, also known as extensions, allow users to modify Chrome in a way which adds extra features and accessibility e.g.  Save to Google Drive. The add-ons are built using web technologies such as JavaScript and are embedded into the user’s browser where they can be turned on and off.

How Has Spyware Infiltrated Chrome Add-ons?

Security researchers have discovered that a number of Chrome add-ons have not been delivering the benefits they promise. These particular extensions, available for free, advertise themselves as providing services which include converting files to different formats and warning about malicious websites. However, these add-ons contain a nasty surprise in the form of spyware. And this spyware has been used to record browsing data and login credentials. Around 70 suspicious add-ons, all uploaded with fake contact details, have been identified and since removed by Google.

How Can You Protect Yourself Against Malicious Add-ons?

The busy digital age we live in means it’s easy to lose focus with what’s happening on our screens. But vigilance is crucial when it comes to threats such as malicious add-ons. Therefore, it’s important that you practice the following when working with extensions:

  • Check Permissions: Whenever you install an add-on it will detail the permissions that it requires to run. These could range from asking for permission to access your hard drive through to analyzing your browsing data. An add-on which asks for a large number of permissions should immediately ring alarm bells. Most important, however, is the nature of these permissions. Anything which feels too invasive should be declined and an alternative sought. 
  • Audit Your Add-ons: It’s always a good idea to monitor the add-ons you have installed in your browser. Any that you deem as no longer necessary should be removed; auditing your add-ons should be carried out every month. This will ensure that your browser does not become bloated with add-ons and minimizes the risk of rogue extensions being present. 
  • Ask a Professional: If in doubt, always reach out to an IT professional before installing an add-on. Their experience of identifying malicious software will allow them to quickly determine whether it is safe or not. And, don’t forget, only ever consider an add-on which provides an invaluable benefit. Otherwise it is recommended to continue without it.

The Best Ways to Keep Your PC Organized

The workplace can be a very stressful environment, so it’s vital that you keep organized. Key to this organization is a PC which doesn’t cause you stress.

It’s likely that your PC is your most important tool at work. After all, they can do almost anything from creative tasks through to data handling and communicating. But this is only possible if your PC remains organized. A badly organized PC will not only hinder your productivity, but it can have a negative impact on the health of your system.

The best workplaces avoid these shortcomings by making sure that employees follow simple, yet effective methods for organizing their PCs. And, as luck would have it, we’re going to share these with you today.

Keeping Your PC Organized

You don’t need a degree in computer science to keep your PC organized. You just need to follow these best practices:

  • Tidy Up Your Desktop: A cluttered desktop quickly becomes difficult to navigate, so it’s crucial that you keep it tidy. Ideally, your desktop should only ever contain shortcuts to the apps you use the most. Saving random files to your desktop may seem quick in the short term, but, in the long term, it makes finding everything on your desktop more difficult. 
  • Audit Your Files: No two files are the same and, accordingly, they will all have different lifespans in terms of usefulness. A spreadsheet on outgoing costs, for example, is likely to be something you regularly use. But a spreadsheet detailing a one off order is going to experience less usage. Therefore, it’s a good idea to regularly go through your files and see which can be archived and which should be kept on your system. This will free up storage on your PC and allow you to find useful files more quickly. 
  • Use a Structured Folder System: Structure is the backbone of all organization and, as a result, it should be integrated into your folder system. And this should be more extensive that just moving everything into My Documents. Everyone, of course, will need and want a different system as our brains all work differently. But what’s crucial is that you breakdown all your files into their simplest terms e.g. specific client names and then into increasingly specific folders such as customer orders, correspondence and contact details. 

Final Thoughts

A well- organized PC allows an employee to work to their full potential. It’s essential that all your employees are in this position as it will provide a massive boost to your productivity. Best of all, the most effective solutions are also some of the easiest to implement. However, consistency is crucial when it comes to organization, so make sure these best practices are regularly followed.

Beware of Fake Resumes Packed with Malware

Hackers are keeping busier than ever and evolving their strategies almost daily; their latest method for attack is to target the humble resume.

Ask any HR professional to tell you how many resumes they receive in a week and they will be able to show you a mountain of them. Even in a business landscape which has changed dramatically over the last 20 years, a resume remains a crucial calling card for employment. And this is why hackers are keen to exploit them. It’s not just that a resume can easily be loaded with malware, it’s more that organizations are so familiar with them they are unlikely to suspect them.

Hackers, of course, thrive on complacency, so it’s time to take a look at what could be lurking inside that next resume.

Malware Laced Resumes

Resume themed scams are on the rise in the US and this latest installment centers around the use of the ZLoader malware. As with many strains of malware, ZLoader is designed to steal credentials. These credentials can include stored passwords and browsing histories, but also banking credentials. And what’s most concerning is that many of these infected resumes are being sent to financial institutions.

But what exactly do these compromised resumes look like? And how are they activated? Well, this is what happens:

  1. Recipient receives an email with a title along the lines of “Job Application” or “Advertised Job”.
  1. Upon opening the email, the recipient is encouraged to open an attached Excel document which claims to be a resume.
  1. If the Excel document is opened, the recipient is then prompted to activate a macro to enable the content.
  1. Unfortunately, activating the macro will only enable a download of the ZLoader malware to the recipient’s PC.
  1. One of ZLoader’s main attack strategies is to infect systems with a malicious app called Zeus which can record keystrokes and steal banking information.

How to Tackle Suspicious Resumes

ZLoader is a form of malware which has been around for several years now. And, thankfully, this means that many anti-malware tools are effective at identifying it and eliminating it. However, if ZLoader is only active for a few minutes it can steal valuable and damaging information. Therefore, it’s always advisable to practice the following:

  • Be Wary of Attachments: Even the most trusted source can be compromised and at the mercy of digital attacks. Say, for example, you receive a resume from a friend – does this mean you should open it without a second thought? The answer is no and this is because your friend’s email address could easily have been hacked. All email attachments should, as a result, be scanned with anti-virus software or checked by an IT professional. 
  • Never Enable Macros: A macro can be very useful for automating certain processes and features in an Office document. But this also makes them perfect for launching malware attacks. If you are ever prompted to enable a macro within an Office document you should verify that it is safe to run. And, again, this should be verified by an IT professional who will have more experience with malicious macros.

Millions of workers are now self-isolating and that means working from home for many people. But how do you make sure that your PC at home is healthy?

The luxury of working from an office is that the equipment there is regularly maintained and fairly new. However, when you have to work from home you will soon realize that your own equipment isn’t in the same shape. We’re all guilty of being a little lazy when we get home and IT maintenance certainly isn’t at the top of most people’s lists. But a little effort goes a long way when it comes to maintaining a PC.

And, best of all, you don’t need to be a fully trained IT technician to carry out a home checkup. In fact, it’s quick and easy as we’re about to show you.

 

How to Maintain Your PC with a Home Checkup

Working from home on your own PC is convenient, but it also puts you and your organization at risk. Therefore, make sure you maximize your productivity and safety by carrying out the following:

  • Install all Updates: We have a habit of ignoring PC updates at home as they get in the way of loading up Netflix. However, it’s important that complacency doesn’t creep into your IT activities at home. You need to make sure that all your software is up to date with the latest patches and firmware. Not only will this ensure that your software is secure, but it will enhance the functionality of your software. Most software will have an auto-update feature, so it’s crucial that this is activated. 
  • Check Your Router: The internet is vital when it comes to remote working. Without an internet connection you won’t be able to connect to your organization’s network. And this will leave you without any of the resources you need. So, it’s essential that your router is working and secure. A good connection is paramount, so you may need to adjust your router position to maximize the signal. And, to safeguard the security of your router, remove any default passwords and create something unique. 
  • Use Security Software: If you haven’t already got security software in place then this needs to be made a priority. It will protect your PC and, if you’re working remotely, strengthen the security of any connections to your business. There are a wide range of options when it comes to security software, so it can be daunting choosing one. It’s recommended that you stick to the industry leaders, so make a beeline to software developed by Kaspersky, McAfee and AVG. And you can rest assured that they provide plenty of free software.

Final Thoughts

The challenges of working from home are likely to be new for many employees. Thankfully, advances in technology mean that this is easier than ever. But you need to make sure that your PC at home is in excellent shape. It is, after all, your most valuable tool when it comes to working remotely. So, to guarantee a PC that is firing on all cylinders, you need to take note of the tips above.
