Anything that can increase your productivity is a godsend. If it’s a simple process it’s even better. And that’s exactly what you can do with a PC shortcut.

Working with a mouse and a keyboard at the same time can become a fiddly task. But, thankfully, much of this complexity can be removed by using PC shortcuts. When we say PC shortcut we’re not referring to the icons on your desktop that launch applications. We’re talking about quick tricks that you can execute in seconds to save you time. These mostly involve either the keyboard or the mouse and you should be able to start implementing them immediately.

Increasing Your Productivity

The best PC shortcuts you should know are:

  • Switching Apps: When you have numerous applications open it can be difficult to navigate your way between them with a mouse. However, if you hold down the ALT key and then tap the TAB key you can quickly switch between each application. A mini preview window will open in the center of the screen to make things as simple as possible.
  • Select a Paragraph: If you want to select an entire paragraph of text to move, copy or delete then you have two options. The first is to manually click and drag your mouse cursor over the entire text. The second, and much quicker, option is to do a triple click of the left mouse button anywhere on the paragraph.
  • Select Everything: If you want to select everything in, for example, a Word document, a text box in any application or even MS Paint, all you have to do is press and hold the CTRL key and then the A key. This will highlight everything instantly and allows you action further processes immediately.
  • Close Your Current Window: The most common way to close a window on your PC is by clicking the X icon in the top right corner. But sometimes this may not be visible or your mouse may not be working correctly. In these cases you can still close the window quickly by pressing and holding the ALT key and then the F4 key.
  • Rescue Your Closed Browser Tab: We’ve all closed a tab on our internet browser by mistake and not been able to remember the address. Rather than digging through your internet history, though, there’s a quick way to re-open that tab. In most internet browsers, if you click and hold the SHIFT key and then the CTRL key and finally the T key, your last closed tab will be re-opened.
  • Zoom In: There’s always a need to zoom in on documents and images, but finding the zoom function in an app isn’t always easy.  There is, however, a quick solution. If you hold down the control key and then move the scroll wheel of a mouse up and down then you should zoom in and out. This works in a wide range of applications such as MS Office, Chrome, Firefox and most graphic design software.

Windows Defender Needs Defending

You would like to think that your security software keeps you secure and, on the whole, it will. But there is the chance it could be turned against you.

One of the most trusted anti-malware tools is Microsoft’s Windows Defender app. Originally launched in 2005 – as Microsoft AntiSpyware – Windows Defender is a free tool which offers real-time protection against infected files and websites. It’s a highly effective piece of software and one that all Windows users should ensure is running. But, in an ironic twist, Windows Defender has fallen victim to a vulnerability. And, as you would expect, hackers have been keen to capitalize on it.

The Windows Defender Vulnerability

The basic process of Windows Defender is that it scans files and activity on a PC for any malicious potential. If these files are considered suspicious then they will be quarantined by Windows Defender; the user then has the option to either restore or delete the file. However, a problem has been discovered in Windows Defender in the form of CVE-2021-1647. This code, allocated by Microsoft, indicates that it’s a vulnerability in Windows Defender which allows remote access to the app.

By allowing remote access to Windows Defender, this vulnerability grants hackers the chance to turn the app against its user. Instead of scanning malicious files and quarantining them, remote users will program Windows Defender to execute these files. Therefore, a hacker could send infected files to a user safe in the knowledge that Windows Defender will do the hard work for them. It’s a serious threat and one which could cause major problems for your network in a matter of seconds. The exploit has been recorded as active in the digital wild, so this demonstrates that hackers have been aware of it for some time.

Defending Windows Defender

It may sound a tall order to defend a piece of software there to defend you, but this is the world we live in. Thankfully, putting safety measures in place is relatively simple. The vulnerability in question has been fixed thanks to a patch swiftly released by Microsoft. This will be installed automatically and requires no work on the user’s part. Naturally, this does not mean that Windows Defender is 100% secure, the threat of further exploits being discovered remains a possibility. But, by ensuring that automatic updates are in place, your system will be safer than before.

Final Thoughts

Vulnerabilities in PCs are all too common and even Microsoft are not immune from these flaws in their products. The Windows Defender vulnerability – and others such as Zerologon – underline the importance of installing updates. The simplest way to secure your PC is by making sure it has the best chance to defend itself. Accordingly, updates need to be installed as soon as possible. When it comes to Microsoft updates, these can be set to install automatically. This gives you the best chance of staying ahead of exploits and any hackers using them.

Online COVID-19 Scams to Be Aware of

COVID-19 has changed the way we live our lives and, not surprisingly, hackers are trying to take advantage of the fear factor behind the virus.

No aspect of life is off-limits to a hacker; if they can turn a situation to their advantage then they will. And this means that all sense of morals and ethics go out of the window. COVID-19, of course, has caused great fear and panic since it emerged, so it’s a subject people take very seriously. And it’s this investment in fear that hackers are looking to exploit. As with most online scams, if it sounds too good to be true then it usually is. But some people are willing to take a risk when COVID-19 is mentioned.

COVID-19 Scams to Look Out For

You should be aware of the usual online threats to look out for, but here are the specific COVID-19 scams you should be aware of at the moment:

  • COVID-19 Vaccine on the Dark Web: Now that vaccines have been approved in the fight against COVID-19, hackers have decided to exploit this demand. And that’s why it’s now possible to find listings for the vaccine on the dark web. Naturally, you should never buy medicine online unless this has been approved by your healthcare professional and the site is genuine. Very little on the Dark Web – an encrypted form of the internet – is genuine, so any marketplace listings that promise a COVID-19 vaccine should be dismissed. 
  • Fake COVID-19 Mapper: Everyone has been intrigued as to the behavior of COVID-19 and its spread, so the opportunity to monitor its spread is appealing. However, hackers have used this curiosity to help spread their malware. Researchers have discovered a PHP malware dropper which disguises itself as a piece of COVID-19 mapping software. Using a compromised website, hackers encourage visitors to download and install the mapping software. But all that is installed is software which downloads further malware. 

How to Combat COVID-19 Scams

The urge to click on sensational news and promises regarding COVID-19 is strong, but it’s crucial that you think long and hard before clicking. There are numerous COVID-19 scams in the digital wild and they are only going to get more sophisticated. As with all online scams and malware, make sure you practice the following:

  • Install all Updates: Malware often takes advantage of outdated software, so make sure that all your software is up to date. All you need to do is install all updates and upgrades as soon as they become available – your PC should automatically prompt you to install these when available.

Beware of Online Tax Scams

Many of us will have started preparing our tax returns and hackers are well aware of this. Therefore, it pays to be aware of the numerous online tax scams.

Nobody likes completing tax returns due to the vast amount of data involved. However, they’re essential for organizations to remain operating. And that’s why we spend hours and hours collecting receipts and details for transactions; this is where all the data builds up. Hackers, of course, like nothing more than getting their hands on huge amounts of data. This data can be used for both financial gain and damaging an organization. Accordingly, tax season is their hunting season.

Tax Scams to Look Out For

Countless tax scams are currently circulating in the digital wild, but these are the most common ones you will encounter:

  • Automatic Tax Payment Deduction: A number of emails have been discovered which claim to originate from the Income Tax Department. These emails falsely claim, in order to generate anxiety, that a tax payment has automatically been deducted from their bank account. An attachment is included which masquerades as a receipt for this transaction. Hackers hope that the recipient’s anxiety and confusion will cause them to open this receipt. Unfortunately, contained within this ‘receipt’ is a slice of malware named W32.Golroted. 
  • Fake Government Websites: A popular method for scamming victims out of money is by designing Government websites which look authentic, but are fake. Using information which has usually been stolen through malicious files or social engineering, these fake websites inform victims that they have received a tax fine. The only way to pay this fine is by wiring payment or purchasing general purchase reloadable cards. However, there is no fine to pay and all the victim will be doing is bankrolling the hackers. 
  • IRS Tax Return is Locked: The last few years have seen the emergence of a phishing email which claims that access to the recipient’s tax return has been restricted. The email is designed to look as though it has been sent by the IRS or, sometimes, the manufactures of the popular TurboTax software. The truth is that the email is fake and has been sent by hackers. The email will urge recipients to click on a link which will take them to a malicious website where their personal information will be stolen.

Staying Safe During the Tax Season

Despite the number of online tax scams it’s easy to stay safe during the tax season. All you have to do is follow these best practices:

  • Remember that the IRS will never contact you by email to discuss the nature of your tax return or your personal details.
  • Verify the true identity of any suspicious links by hovering your mouse cursor over the link. A popup will then display where the link will send you.
  • Never send personal documents to unsolicited email requests as it is likely that a hacker is trying to harvest your details
  • Emails that claim to be from official organizations, but do not use your name are to be treated as highly suspicious and should be deleted.

Five Signs That You’ve Been Hacked

Dec 2020

Having your organization’s network breached is a major cyber disaster, so identifying a breach quickly is crucial. But how do you know you’ve been hacked?

Protecting your organizations networks and data is essential, but with the huge number of hacks taking place it’s not easy. And if a breach occurs this can cause multiple problems for your business such as data theft, ransomware demands and damaged networks. When it comes to these attacks then there’s one factor which is essential: speed. The sooner you realize you have been hacked, the sooner you can set about cleansing your system. Hackers may be evolving their methods to become even stealthier, but there are still certain tell-tale signs that you’ve been hacked.

You may not be aware of these indicators, so we’re going to share five signs that you’ve been hacked.

What Are the Signs of Being Hacked?

The most obvious indicators of your PC being hacked are the following:

  1. Password Not Working: One of the simplest signs of falling victim to a hack is when your password isn’t working. Sure, there’s a chance that you’ve mistyped it or simply forgotten it, but alarm bells should start ringing if you’re convinced you’ve got it right. And, if you have activated two-factor authentication and this is also not working, it’s likely your login credentials have been breached. 
  1. Your Browser Keeps Redirecting: If you discover that your internet browser is behaving strangely then this is a sign you have been hacked. Your browser should, for example, open up with either your company home page or Google, but a hacked browser is likely to take you straight to a malicious website. Such a website will prompt you to download files in an attempt to infect your PC with malware. If this happens then you need to close the browser as soon as possible and advise an IT professional. 
  1. Your Anti-malware is Disabled: It’s unlikely that you will ever need to disable your anti-malware software, so any indication of this being disabled could signal a hack. After all, hackers want to make their life as easy as possible. Therefore, if they take control of your PC, the simplest way to download malware undetected is to disable your defenses. Make a point of regularly checking the status of your anti-malware software to stay safe. 
  1. A Mouse Cursor With a Mind of Its Own: Your mouse cursor should, if you’re not moving the mouse, stay still. You may occasionally get a small amount of movement from hardware issues, but any significant movement indicates a hack. If your PCs defenses have been breached then hackers can easily take control of your PC. And this can be evident from unauthorized activity taking place on the screen. So, if you find that applications are being launched without your permission, power off your PC and immediately get it investigated. 
  1. Your PC is Slowing Down: A PC can slow down when it’s processing multiple tasks at once, but one which is slowing down for no particular reason is one to be suspicious of. It could be, for example, that your PC has fallen victim to a botnet and your PCs processing power is being harnessed for attacks elsewhere. If, after restarting your PC, it continues to lag then it’s critical that you take the necessary measures to isolate that PC before looking deeper.
