We live in a high speed age which allows us to be more productive than ever, but if anything can throw a wrench in the works it’s a slow PC.

The experience of a slow and sluggish PC is one that everyone is familiar with. And dealing with this frustration never gets easier. In fact, a PC which regularly slows down can have a serious impact on your job productivity. The complexities of the inner workings of a PC mean that identifying the exact cause is difficult. But this doesn’t mean you need to continue struggling.
It’s possible, with relative ease, to employ a number of methods and practices that will help restore your PCs speed.

5 Steps Towards a Faster PC

If you want to start ramping your productivity back up then make sure you look at the following:

  1. Defragment Your Hard Drive: A PC is, essentially, a data storage device. But the data stored on a PC needs to be retrieved every time it’s required. And the more data you store on your PC the more uneven this data distribution is. The end result is fragmented data that becomes increasingly harder to piece together. Naturally, this means that processes take longer to complete. Performing a disk defragmentation will help to reorganize your data and can easily be achieved with the Microsoft Drive Optimizer app.
  2. Browser Add-Ons: Installing add-ons to your web browser can help to maximize your online productivity, but too many can start to slow down your browsing experience. It’s common, however, to install add-ons that soon fall into disuse and no longer serve any purpose. Therefore, if your speed issues are only apparent when you’re using your browser, it may be worth evaluating your active add-ons and disabling any you don’t need.
  3. Start-up Programs: When a PC loads up it will automatically load up a long list of programs that are listed in your System Configuration. The more programs that are listed in System Configuration then the longer your PC will take to load up. Many of these programs, though, are not necessary during the start-up process e.g. a messaging app that you don’t use regularly. To avoid a bloated start-up experience just head into MSConfig and check what’s included in your start-up.
  4. Hard Drive Space: Your hard drive may, for example, have a capacity of 500GB but it’s not recommended to fill it to breaking point. The operating system on your PC needs a certain amount of hard drive space to carry out essential tasks such as creating temporary files. And if this space isn’t available then your PC will struggle to operate correctly. Regularly evaluating what is on your PC and what can be removed is crucial to avoid this.
  5. Malware: Hackers are keen to take control of PCs through the use of resource-heavy malware. Depending on the nature of the malware, such as a DDoS attack, your PCs memory can soon become overloaded and grind to a halt. Accordingly, you need to maintain good security practices to prevent the impact of malware.

How to Protect Yourself against Social Engineering

Hackers thrive upon deception and the result of this endeavor is social engineering. It’s a powerful tactic and one you need to protect yourself from.

Social engineering has been used to deploy attacks such as the Coronavirus malware and the recent attack on high profile Twitter accounts. The method is intriguing due to its sophistication and its human element. Rather than relying on complex coding techniques to outwit computer systems, social engineering takes advantage of human naivety. More importantly, however, is the sheer destruction that it can cause.

The world is a perilous place at the best times, but now more than ever we need to make sure we protect ourselves and our businesses. One of the best ways to get started is by reinforcing the barricades against social engineering.

What is Social Engineering?

Manipulation is, in a word, exactly what social engineering is. But you’re going to need a little more information than that, so let’s take a closer look.
Social engineering is a process in which one party seeks to deceive individuals into revealing sensitive information. When it comes to the world of IT this sensitive data tends to relate to login credentials, but can also involve transferring sensitive documents such as employee records. These attacks are commonly executed through the use of phishing emails, but this is not the only technique. It’s possible for hackers to carry out social engineering attacks over the telephone and even face to face.

The Best Ways to Protect Yourself

Protecting yourself against social engineering takes a concerted effort. You can’t rely on software alone to protect you. Luckily, you can strengthen your personal defenses by practicing the following:

• Take Your Time: Social engineering relies on a lack of caution on the victim’s part. Therefore, it’s crucial that you always take your time when it comes to any form of communication. A social engineer will do their best to force you into making a quick decision e.g. clicking a link or disclosing your password. To counter this, evaluate all requests and press for answers if you feel even slightly suspicious.

• Use Email Filters: There have been great advances made in email filters over the course of the last 20 years. Where these junk filters once had relatively little use they are now highly intelligent. Enabling your email filters will enhance your security and prevent the majority of phishing emails making their way into your inbox. This reduces your risk and stops you from engaging with a social engineer.

• Too Good to Be True: As with all areas of life, if something sounds too good to be true then it makes sense to be suspicious. After all, it’s unlikely that a representative for an African prince wants to deposit millions of dollars into your bank account. And, if they did, why would they require your social security number? And your workplace login credentials? As a rule of thumb, if it sounds like a scam then it probably is and should be deleted.

• Is the Source Genuine: If an email says that it’s from your bank then this doesn’t mean it’s from your bank. Likewise, a phone call from your HR team isn’t necessarily genuine. Hackers specialize in trickery and deception, so they won’t shy away from such blatant and direct approaches. Always check every request for details such genuine URL details (by hovering over a link) and only transmitting sensitive data to internal email addresses.

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.

Passwords are the single most important safety tool at your disposal. But passwords need to be strong. And creating strong passwords is far from easy.

Thankfully, Google has solved this problem for us. All you need to do is get on board with their new service: Password Checkup. Not sure what Password Checkup is? Well, as luck would have it, we’ve put together a quick guide for you.

The Problems with Passwords

There are certain passwords which are used time and time again. And not just by individuals. We’re talking millions of people all over the world using similar passwords. These includes all the old favorites such as Password123, abc123 and Passw0rd. Sure, these are easy to remember. But their ubiquity means that they represent a major security risk.

Modern security techniques, of course, have negated the impact of weak passwords, but only marginally. Two-factor authentication, for example, puts an extra barrier behind passwords. But this is not there to be treated as a security option to fall back on. That’s why you need to start with a strong password and work from there.

But the sheer number of sites and applications we log in to in the 21st century is mind-boggling. Memorizing all of these passwords requires some serious memory skills. The quickest solution to this problem is to write them all down. But, that’s right, you’ve guessed it. Writing down passwords is yet another security threat.

Password Checkup is the Solution

Google, the great innovator of technology, has decided to simplify and improve the password process. And the result is Password Checkup.

Google Chrome and individual Google accounts have long had a built in password manager. This has allowed users to not only generate passwords, but also store them securely. Users, therefore, have been able to browse online securely and access all their services with ease. But this isn’t enough for Google. They want to push the concept a little further.

And this is where the Password Checkup extension comes in. Available from the Chrome web store, all it takes is a simple install process to activate Password Checkup for Chrome. But what does it do? Well, its main objectives are:

  • Identifying whether your username/password combination has been exposed. Breaches of third-party databases are rife. But, thanks to the data at its disposal, Password Checkup can advise you of this and prompt a change of password.
  • To analyze your existing passwords and recommend strengthening them if required. Your passwords may be securely stored in Chrome, but this doesn’t mean they can’t benefit from strengthening further.

The Password Checkup extension isn’t the only method in which you can use the service. You can also log on at passwords.google.com to manage and analyze your stored passwords.

Stay Safe with Password Checkup

All it takes is for one password to be breached to cause untold damage. But Password Checkup helps to nullify this threat. Thanks to its clever technology, Password Checkup keeps you on top of weak and exposed passwords. This knowledge allows you to act quickly and effectively to secure your passwords. And, with Password Checkup soon to be an integral feature of Chrome, the future looks bright and secure.

WordPress Sites are Quietly Downloading Malware

WordPress is a popular platform for building websites, but this popularity has made it a target for hackers. And it’s now being used to launch hacks.

It’s estimated that around 75 million websites use WordPress as the backbone for their content. But not even the largest and most profitable tech companies are immune from hacking. Vulnerabilities are present in almost every piece of software ever designed. And when these vulnerabilities are discovered they will be exploited almost instantly by hackers. WordPress has fallen foul of this all too common scenario and, as a result, 100,000 web users have felt the attentions of these hackers.

Due to the ubiquity of WordPress websites it’s likely that your organization engages with them on a daily basis. It may even be that your organization’s website is hosted through WordPress. Either way, the threat presented is one you want to avoid, so let’s take a look at it.

How were the WordPress Sites Compromised?

Security experts Zscaler were the first people to identify that WordPress sites had been compromised. The nature of the hack is sophisticated, but relatively simple to pull off. After discovering a vulnerability in the ‘theme’ plugin, which is included in WordPress sites, the hackers were able to infect the sites with malicious scripts. These scripts were a form of code which redirected visitors to a Flash Player update alert. However, this urgent update was fake and all that would be downloaded was a malicious file.

The file in question was a Remote Access Trojan (RAT) which allowed remote access to the infected PC. And, with unrestrained access, the hackers were granted the opportunity to download and distribute malware as well as the chance to compromise data. But this isn’t the only way in which the malware infects PCs. Those using the Chrome browser faced an additional threat. Upon visiting the infected WordPress sites, Chrome users were prompted to download an update for the ‘PT Sans’ font. Again, this is a deceptive request and downloads the RAT.

Protecting Against the WordPress Hack

If you own a website which is built on the foundations of WordPress then it’s crucial that you update the associated content management system. This will instantly prevent your website from cultivating the hack and protect your visitors.

Unfortunately, it’s not always possible to tell when a website is using the WordPress system, so you should make sure you practice the following:

  • Scrutinize all Popups: The sheer range of dangerous popups means that they should always be scrutinized. Fake updates tend to stress an extreme urgency which is designed to tempt users into clicking them without checking. Instead, users need to take a second and consult with an IT professional to verify the update is genuine. 
  • Install Anti-Virus Software: It’s vital that your organization uses anti-virus software. Not only can it identify threats such as the WordPress hack, but they are regularly updated. This ensures that your organization is protected from all the latest threats.
