Almost all cyber-attacks are due a common denominator: a mistake. We aren’t perfect, of course, but we can limit number of IT security mistakes we make.

Working on a PC is far from straightforward and, as a result, the sheer number of complex routines you must work through leaves plenty of room for mistakes. At the same time, all a hacker needs to take control of your system is a few milliseconds. Accordingly, even the smallest security mistake can leave your PC at the mercy of a hacker. However, by understanding what the most common, and usually simplest, IT security mistakes are, you can strengthen your IT defenses almost immediately.

Start Eliminating These Mistakes Today

If you want to make sure your IT infrastructure is safe from hackers, then you need to avoid these five IT security mistakes:

  1. Not locking your screen: you may trust your work colleagues, but the fact remains that numerous people will enter your organization’s premises throughout the day. Some may be familiar, some may not. And that’s why it’s crucial you lock your screen. All you have to do is hit the Windows button and the L key; your screen will be locked with a password and the contents of your PC immediately protected.
  • Underestimating your value as a target: threat actors are malicious and, although they are certainly interested in big targets, they’re equally likely to target smaller organizations too. Additionally, many cyber-attacks are automated and don’t discriminate against who they attack. Therefore, never assume that your small business is of no concern to hackers. Remain vigilant and practice good IT security.
  • Passwords on Post-it notes: we all know that remembering passwords is difficult, but the biggest mistake you can make is by writing your password on a Post-it note. And then sticking it to your monitor. Sure, it’s convenient for you, but it’s also highly convenient for anyone looking to compromise your PC. Instead, create passwords you can easily remember, but are difficult for anyone else to crack.
  • Assuming email attachments are safe: ever since email became a mainstay of modern communications, it has carried a huge risk of delivering malware through email attachments. Most concerning of all, these infected attachments may be sent by email contacts you consider safe, it could even be your colleague sitting next to you. Threat actors can easily take control of a victim’s email address book and email malware under the guise of the victim’s email address. And that’s why you should evaluate every email you receive.

As with all aspects of modern life, everything is a target for cybercriminals, even war. And this has been demonstrated with wiper malware attacking Ukraine.

Amidst its conflict with Russian, Ukraine has also had to contend with hundreds of its computers falling victim to a strain of data wiper malware. As the name suggests, wiper malware is used to wipe hard drives clean of any data. While this sounds like ransomware, and indeed wiper malware often promises the return of data for a fee, the chances of retrieving this data from the hackers is zero. It’s a powerful and destructive cyber-attack, one which has the potential to cause significant damage not just to security, but also IT infrastructures.

It’s an attack method which could strike anywhere at any time, you don’t have to be in Ukraine. Therefore, it’s crucial that we understand how wiper malware works. And, more importantly, how to protect your data.

The Cyber-Attack on Ukraine

The wiper malware in this opportunistic attack, which comes at a time of intense internal chaos, has been identified as HermeticWiper. It followed on from an earlier attack which had targeted Ukraine’s banks through a number of co-ordinated DDoS attacks. It came several hours before Russia launched its invasion campaign but, as yet, nobody has been identified as being behind the attack. What is known is that it’s a new strain of malware which, according to its date stamp, was created towards the end of 2021. Clearly, this attack had been in the works for some time.

Once downloaded onto a PC, HermeticWiper sets about wiping all the data from its hard drive. It achieves this objective by taking advantage of existing disc and storage management software. With this software compromised, HermeticWiper turns it against the PC to corrupt any data within its grasp and then reboots the PC. But it doesn’t stop there. HermeticWiper is also keen to attack any data recover software on the machine and also interferes with the hard drive’s rebooting system.

How Do You Stop Wiper Malware?

The government of Ukraine has a significant reach and has appealed to its native hackers to assist in protecting the country’s IT infrastructures. Unfortunately, almost all organizations will struggle to raise this level of support. But there’s still plenty you can do:

We process and evaluate a huge amount of data every day, so external hard drives are vital for our storage needs. But how do we get the best out of them?

Capable of holding up to 12TB (that’s 12,000GB) and easily connected via USB, external hard drives are an affordable solution to data storage. However, when a device is holding so much data it’s important that you know how to use it properly. An external hard drive which is used correctly and maintained will keep your data safe for years. But one which is mismanaged can soon lead to a data disaster. And no business needs that.

Luckily, we’ve put together a few pointers on the best ways to use an external hard drive.

Getting the Best Out of Your External Hard Drive

Making sure that your device remains operational and productive is simple as long as you follow these best practices:

  • Don’t Move Your Drive When Transferring Data: Beneath their solid exterior, external hard drives are delicate pieces of kit. This is particularly true for Hard Disk Drives which contain spinning and moving parts. Therefore, moving or jostling your external drive when it is transferring data has the potential to not only damage the device, but also create data errors. Make sure that your device is properly connected, on a flat surface and not in the way of your general PC activities e.g. using the mouse and keyboard. 
  • Format Your Drive as NTFS: There are many reasons for formatting your external hard drive, but it’s important that you format your drive as NTFS. Using this method, as opposed to FAT32, is perfect when your device is mostly used with Windows PCs. NTFS formatting provides faster results and has the added bonus of making your drive less susceptible to disk failure. 
  • Run CHKDSK: Better known as Check Disk, CHKDSK is a handy system tool which should regularly be used to check the status of your external drive. It has the capacity to identity any file system errors and repair them. This gives you the dual benefits of a stable folder structure on your device and less chance of it crashing. 
  • Better to Repair than Replace: It can be frustrating when an external hard drive fails, but it’s often simpler to replace a troublesome device rather than repairing it. The labor, and associated costs, to repair an external hard drive will usually be more expensive than a replacement. And, as our next point will show, this shouldn’t compromise your data too much. 

If you can follow the advice above then you should be guaranteed a hassle-free experience with your external drive. And you can rest assured that your data will be safe and available at all times.

Hardware can easily become compromised, stolen or damaged. And this can leave you without crucial data. But the 3-2-1 backup method is here to help.

Data disasters are most often caused by hardware failure, human error or cyber-attacks. Regardless of the cause, your organization needs a good backup strategy in place. You need to be able to retrieve your data in the event of an emergency. Without a backup strategy you will struggle to recover and this will have a major impact on your productivity. And that’s why the 3-2-1 backup method has proved to be so popular with businesses.

Data protection has never been more important that today, so we’re going to take a look at how the 3-2-1 backup method can protect your data.

What is the 3-2-1 Backup Method?

The principle behind the 3-2-1 backup method lies in its name:

Let’s take a closer look at each part of the method to help you understand the thinking behind it:

  • Keeping at Least 3 Copies of Your Data: To keep just one backup copy of your data is careless. Say, for example, your data is compromised by ransomware. An option would be to retrieve your backup data from an external hard drive. But what if you discover this device has been damaged in some way? You need an alternative solution. And this could be accessing a USB drive or connecting to a cloud storage solution. The minimum number of copies you should keep is three, but there’s no maximum. You can keep three, five or fifty. 
  • Keeping 2 of these Copies on Local Devices: Onsite backups are essential for keeping your productivity in place. Data disasters are unpredictable and can have an instant impact. Therefore, you need to make sure that you have your backup data close to hand. This approach will allow you to quickly implement any compromised data and establish normal working practices. Again, it’s important to have more than one local backup available to safeguard against any technical issues. 
  • Keeping at Least 1 Copy Offsite: If you want to reap the benefits of a complete backup strategy you need to keep one copy offsite. Advances in cloud computing mean that it’s easier than ever to store data offsite. And this can pay dividends in the case of a local disaster. If, for example, you are hit by a hurricane or a flood, all your local backups could be damaged. It doesn’t matter if you’ve got three or three hundred. But if you keep at least one copy in the cloud you are ensuring comprehensive data protection is in place. 

Final Thoughts 

A good backup strategy is vital in protecting your data in the event of a data disaster. And it pays to be comprehensive in the manner in which you protect your data. The 3-2-1 backup method is the perfect way in which to achieve this.

5 Quick Tips for Maintaining Your PC

Like any other electrical product, PCs are prone to failure due to the number of components involved. But a well maintained PC is likely to last longer.

Your organization’s PCs are likely to be crucial for your day-to-day operations, so you need to make sure they are in good working order. After all, you wouldn’t let your car fall into a state of disrepair. You would make sure your car is regularly serviced and maintained to make sure you could continue getting from A to B. And a PC is no different. But, thankfully, you don’t need to pull on your overalls or take your PC to a garage to maintain it. You can complete regular maintenance’s quickly and easily from your office.

How to Maintain Your PC

If you want to keep your PC working to its full potential and optimize its productivity then make sure you practice the following:

  1. Declutter Your Startup: When your PC starts booting up it also starts loading all the programs which are defaulted to load at startup. However, not all of these are necessary. And the more programs that need to load then the longer the startup time. Therefore, head to Task Manager on your PC and click on the Startup tab. From here you can remove any unnecessary programs and speed up your boot time. 
  1. Install all Updates: It’s important that all recommended updates are installed immediately. These updates aren’t just related to security issues. Sometimes they are released by developers in order to fix bugs in their software and enhance the product. Ultimately, an update is one of the quickest ways to optimize your PC and ensure that it’s well protected. 
  1. Always Shutdown Correctly: The shutdown process on a PC can be a frustrating affair due to the time taken, but it’s important that you follow this procedure to the letter. It may be quicker to turn the PC off at the mains, but this approach can lead to corrupted files. Instead, make sure you save all your files and close each application down before waiting for the PC to run through the shutdown procedure. 
  1. Carry out a Registry Clean: Your PCs registry is a giant database which logs everything that happens on your PC. If you install a program or change your password then this is logged in the registry. And, over time, the amount of data stored here starts building up. This may not be too much of a problem with newer PCs, but if you’re running an older PC this can create performance issues. However, you must proceed with caution and it’s recommended that you use a highly rated registry cleaner to perform the clean to avoid issues. 
  1. Delete Unwanted Programs: It’s natural that your PC will gradually accumulate more and more installed programs over time. But not all of these programs remain relevant. And if you are running programs that are no longer relevant then they are putting an unnecessary strain on your PCs memory. So, every couple of months, make sure that you evaluate the programs installed on your PC. This will give you a clear idea of what can be uninstalled and what can remain. The result will be improved performance for those that remain.
