It’s vital, if you want your PC to remain safe and secure, to install all software updates and patches. The alternative is, of course, that you get hacked.

Now, no one wants their PC to get hacked. The fallout from such a scenario can only spell disaster for a business. We’re talking stolen data, disrupted IT operations, financial damage and a major drop in productivity. And no one wants that. Certainly not a business and certainly not their customers. But hacking is a major threat in today’s digital workplace. In the first half of 2019 alone, a total of 4.1 billion records were compromised. It’s a figure which is clearly huge, but it’s also one that could be significantly reduced if organizations updated their software regularly.

So, to help you keep your software updated, we’re going to run through the basics of updating and securing your software.

What are Software Updates?

It’s difficult to create a flawless piece of software. The complexity of coding means that, even when developers feel their application is finished, it’s likely that minor problems will remain. And, in most cases, the only impact of these errors will be felt in the application’s functionality. However, on occasion, these minor flaws can represent major security issues. Hackers, if they are to be commended on anything, are highly persistent. And, if they can find a vulnerability in a piece of software, you can rest assured that they will exploit it.

This is why software updates and patches are crucial. The most common update that most PC users will encounter is an operating system update. These are regularly released by developers in order to counter security issues which have been discovered. These updates, in their simplest terms, patch the software. Following the patch process, your operating system will be considered more secure and functional. Unfortunately, many organizations are either too busy to worry about updates or they fail to understand their importance. And that’s why you need to know the best ways to keep your software updated.

How Do You Update Your Software?

Updating software on a PC is straightforward and simple, but only if you know how. Therefore, it’s important that you practice the following:

  • Allow Automatic Updates: The sheer number of updates that are required for multiple applications is mind-boggling. And the time taken to action these updates is significant. But, with this in mind, most pieces of software allow you to select an automatic update option. This takes the pain out of authorizing and conducting every new update and patch. The setting is most commonly found in the updates section of an application’s control panel. 
  • Visit Developer’s Websites: It’s good practice to regularly visit the websites of developers to make sure you’re working with the latest updates. Adobe Flash Player and JavaPress, for example, can both be verified by visiting their respective websites. The relevant software is quickly analyzed to determine which version it is. And, if any updates are outstanding, the user will be prompted to install these or upgrade to a new version.

How to Keep Your Remote Workers Secure

Advances in technology have created an environment where clocking in at the office is no longer required. But remote working is not without security risks.

Remote working is on the rise with many organizations offering this option to their employees. The benefits of remote working are numerous and apply to both employers and employees. But, away from the relative security of the office, remote working poses a number of security risks. Therefore, it’s crucial that your business finds a healthy balance. You need to develop a remote working environment which not only provides flexibility, but is also secure.

Achieving this combination is relatively easy. You just need to know how. And, thankfully, we’re going to show you how.

Keeping Remote Workers Safe

Remote workers are, to a certain degree, a law unto themselves. After all, working from a remote location means that immediate monitoring is next to impossible. So, you need to invest a certain level of trust. But we’re living in an age where cyber-attacks are reaching record highs. And this is why you need to help protect your employees in the following ways:

  • Security Training: Your employees are your main defense against security attacks, so they need the correct training to remain safe. And this applies to remote workers more than any other employee. Regular training on security protocols and updates on contemporary threats need to be put in place. 
  • Use Two-Factor Authentication: One of the surest ways to secure your remote workers is by putting two-factor authentication in place. This is a security procedure by which users have to provide additional information alongside a username and password. This can take the form of a PIN number sent to a mobile device or a secret question. It only takes seconds to pass two-factor authentication, but the enhanced security it provides is priceless. 
  • Monitor Devices Closely: It’s important to keep a regular eye on any company issued devices that are used remotely. For one thing, you need to make sure that your employees are working as they should be. But, when it comes to security, you should make sure you are analyzing their usage e.g. visiting malicious websites and connecting external devices such as USB drives. 
  • Implement a VPN: A virtual private network (VPN) is essential for remote workers. It’s difficult to guarantee that remote connections are fully secure, but a VPN solves this problem. Using multiple layers of encryption, a VPN protects any data being transmitted or received by remote workers. Therefore, data such as financial records and customer details will be secured from any external forces. 
  • Use Strong Passwords: This may sound simple, but a weak password is easier to crack than a complex one. However, this advice is ignored more often than you would think. So, you need to remind your employees of the importance of password security. And you need to prompt them to regularly change their passwords. Thankfully, creating strong and unique passwords is easy once you learn the basics.

The coronavirus is the latest health scare to be spreading across the globe. Hackers, as clever as ever, are using this fear to spread malware.

Hackers are innovative criminals and are constantly on the lookout for exploits. Sometimes these are software vulnerabilities that leave back door opens. But these exploits can also take the form of social engineering. And this is how hackers are taking advantage of the panic caused by the coronavirus.

It’s always important to safeguard your defenses with the best security software, but this isn’t enough. Threats such as social engineering require a concerted effort to be made by individuals. So that’s why we’re going to take a look at the threat posed by the coronavirus malware.

What is the Coronavirus Malware?

The entire planet is preparing and educating themselves for the fight against the coronavirus. Naturally, this means that millions of people are heading online to learn more about the disease. Now, although the internet poses no threat to your physical health, the same cannot be said for your digital security. And this is because cyber criminals are disguising malware as educational documents on the coronavirus.

These documents, which have been detected as docx, pdf and mp4 variants, promise to be helpful. But, rather than containing useful information on the coronavirus, these documents actually contain a wide range of malware threats. So far, Kaspersky, have identified 10 file variants that include various Trojans and worms. However, given the on-going threat of the coronavirus, it’s likely that the number of malware threats will increase.

The most common method to spread this malware is through phishing emails. And, as with all social engineering, the bait is very convincing. The emails claim to be distributed by the Centers for Disease Control and Prevention, but this is a false claim. If you look a little closer you will discover that the domain these are sent from is incorrect. The official domain for the CDC is cdc.gov but these malicious emails actually originate from cdc-gov.org. These emails contain a link which, rather than taking you to an advice page, takes you to a fake web page that aims to steal your credentials.

How to Protect Yourself Against the Coronavirus Malware

Hackers are using a variety of methods to exploit the coronavirus to cause digital chaos. Infected documents threaten the security of your PC systems and phishing emails have the potential to steal personal information. Therefore, you need to protect yourself by following these best practices:

  • Only Open Trusted Files: The only files that you should ever open on a PC are ones that come from a trusted source. If there’s even the smallest doubt over the legitimacy of a file you shouldn’t download it. Always check with an IT professional before going any further. 
  • Always Hover Over Links: Emails, and websites, can easily display a web link which disguises its true destination. A link that, for example, claims it will send you to an official government website can easily send you somewhere else. However, if you hover your mouse cursor over a link, this will prompt a popup which displays exactly where it will take you. 
  • Install Security Software: A sure fire way to avoid the wrath of malicious websites is by working with security software. These applications are regularly updated with details of malicious websites and will put an instant block on visiting them.

We’ve all had to boot into safe mode on our PCs at some point and you would assume it’s a safe environment. But the Snatch malware is proving otherwise.

Safe mode is a configuration mode that you can request your PC to boot into at startup. In safe mode, your PC will only execute essential applications. The functions of your PC will be limited, but it’s the perfect environment for fixing problems and removing various forms of malware. But it appears that Snatch is a brand of malware which can thrive in safe mode.

Snatch is a multi-factor threat which can cause real damage to your business, so it’s a slice of malware that you need to be protecting yourself against. To give you a head start, we’ve put together a quick lowdown on Snatch.

What is Snatch?

Snatch is a newly discovered malware variant which contains two key threats: a ransomware function and the ability to log and steal user data. It’s not the first piece of malware to come loaded with these threats, but its infection strategies are unique. Using brute force attacks, Snatch is targeting the PCs of various organizations. So far, this sounds far from unusual as brute force attacks are a fairly conventional form of hacking. But Snatch has a unique strategy.

Following the initial infection, Snatch forces the PC to reboot. And it’s at this point that Snatch informs the PC to boot into safe mode. It’s believed that this unusual, yet clever, step is initiated in order to avoid anti-virus software which is often disabled in safe mode. From here it can execute its malicious payload. Snatch will then begin encrypting files and demanding ransoms that have been as high as $35,000. There is also evidence that surveillance threats are present in Snatch, so data harvesting is likely to start once the infection is unleashed.

Protecting Yourself from Snatch

The Snatch malware has the capability to cause extensive damage to your organization in terms of both finances and credibility. It’s also disturbingly efficient as it deletes any volume shadow copies of the files it encrypts. By deleting these volume shadow copies, Snatch is ensuring that it’s impossible to restore the encrypted files. Therefore, it’s crucial that you protect your PCs from Snatch by:

  • Practice Good IT Security: The backbone of any secure network is based upon the actions of those using it. And this is why it’s important that all your users understand the basics of IT security. By embracing these practices it’s possible to keep your PCs protected from the majority of majority of malware.

Dec 2019

Google’s Chrome browser is a popular browser and one that it is relatively secure. But it can be made even safer with the correct plugins.

It’s estimated that over half of all web traffic goes through Chrome browsers and this popularity is down to its innovation and simple interface. However, the success of Chrome has made it a target of hackers. And this has been highlighted by the recent WizardOpium vulnerability which required a swift patch from Google. There’s added danger for Chrome users from more generalized online threats such as malicious websites and data security concerns. Thankfully, help is at hand for web users in the form of security plugins.

And, to help you enhance your Chrome experience, we’re going to examine the best plugins for browsing safely in Chrome.

What is a Plugin?

You may not be familiar with plugins, so it’s probably a good idea that we start by explaining them. A plugin is a piece of software which, as the name suggests, ‘plugs in’ in to your browser. Acting as an additional software component, a plugin adds extra features to your browser. The types of plugin availability aren’t just limited to security features either. Adobe’s Flash player, for example, is probably one of the most well-known browser plugins.

Chromes Best Security Plugins

It’s now time to take a look at the best plugins for browsing safely in Chrome:

  • Ghostery: A privacy ad blocker, Ghostery grants Chrome the opportunity to block adverts and stop data trackers from harvesting your data. The plugin allows you to customize which ads and trackers remain active whilst blocking the more suspicious ones. And, best of all, by blocking ads and data trackers you will speed up the load time of webpages.
  • Web of Trust: It’s estimated that there are up to 18.5 million malicious websites online, so you need to be careful where you browse. With a plugin such as Web of Trust you can maximize your safety. Not only does Web of Trust advise you when you land on an unsafe website, but it also displays ‘reputation’ icons next to the results generated by search engines.
  • Blur: Passwords are a crucial element of safe web browsing, but they need to be kept secure. If your passwords are compromised then you’re at risk of having your personal data stolen. Blur helps you to avoid this. It’s a powerful plugin which can generate strong passwords while also encrypting and saving them. This ensures that there’s no need to memorize or write down you passwords; you can just click and go. 
  • HTTPS Everywhere: The best websites are those with a URL which starts with https rather than just http. The additional S of https indicates that it’s a secure website. However, if you have installed the HTTPS Everywhere plugin then, in most cases, it will be able to automatically switch a http site to a more secure https version.
