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.

We visit websites on a daily basis, but how do we know how safe they are? No matter how genuine they look there’s every risk they’re a malicious website.

It’s estimated that up to 18.5 million websites are infected with malicious content. That’s around 1% of the total number of websites online. It may not sound a huge percentage, but it’s a percentage that could cause your business significant trouble.  And it’s a problem that most organizations aren’t entirely clear on. Malicious emails, for example, are well known due to the scare stories that flood our newsfeeds. But we’re less informed about malicious websites. And that’s what makes them dangerous.

However, if you’re able to understand the basics of a malicious website then you’re going to be in a much better position to avoid falling victim. So, what are malicious websites?

What is a Malicious Website?

A malicious website is like any other website on the internet: you connect to it with a browser. But if you dig a little deeper you’ll soon realize why it’s unlikely to become one of your favorite websites. The main objective of a malicious website is to install malware on to your PC. And, in most cases, it won’t even ask permission. The moment that you land on a malicious website is the moment that the malware starts downloading.

But why is a malicious website so misleading? Well, hackers are incredibly clever and they’re even more deceptive. That’s why they design malicious websites to look as genuine as possible. We, as humans, make quick decisions based on first impressions and, in this busy digital age, this is never truer than when online. Malicious websites take full advantage of this. And the false layer of trust that this engenders can soon lead to us clicking on links that we really shouldn’t.

How Do You Protect Yourself from Malicious Websites?

No one wants to fall victim to a malicious website. But, without a prior knowledge of how to protect yourself, this is difficult. Thankfully we’re here to make things easier. That’s why we’ve put together this amazing set of safety tips:

  • Always keep your software updated and install the latest patches as soon as possible. Malicious websites are often used to distribute malware that targets software vulnerabilities. With this updated protection in place you can minimize one of the main threats of malicious websites.
  • It’s vital that you never install any software you’re unfamiliar with. Malicious websites are sometimes courteous enough to ask permission before installing their malicious content. And it’s easy to click the Yes button just to clear the screen of yet another pop-up window. But it can spell disaster for your PC. Therefore, always read pop-up windows carefully and, if you don’t trust it, leave that website immediately.
  • If you’re sent a link to a website that’s unfamiliar then you shouldn’t click it. But you should do some research first. The best way to verify a mystery link is to type that link into the search box of a search engine. The results should soon highlight whether that web address is trustworthy or dangerous.
  • Install internet security software that can identify malicious websites before they’re loaded up. Knowledge of malicious websites can spread quickly and this has led to massive databases being created to help alert users to those that contain a threat.

What are the Basics of PC Exploits?

At the center of all unauthorized access to your computers or servers is a PC exploit. What are these exploits, though, and how do you protect against them?

Without the presence of an exploit, hackers find themselves in a position where gaining access to a victim’s PC is incredibly difficult. However, it suddenly becomes a lot easier if there’s an exploit available that they can take advantage of. It’s probably becoming clear, very quickly, that it’s crucial that you, as a PC user, also know about the existence of these exploits. Unfortunately, the level of knowledge that the average organization has regarding the nature of exploits is disturbingly low. And that’s why so many businesses fall victim to PC exploits.

If, however, your organization can begin to understand even the basics of PC exploits, then you stand to make your IT operations considerably more secure.

What is an Exploit?

The simplest way of looking at an exploit is by describing it as a hole in a security gate. Once hackers become aware of this hole then they can easily bypass your security by climbing through the hole impeded. If we’re talking slightly more technically, then this hole isn’t necessarily a hole but some form of weakness in your PC. These weaknesses can be found in operating systems, software code and any applications installed on your network. And the impact that exploits can have on these components can be devastating.

What Does an Exploit Do?

An exploit can work in a number of different ways; most commonly, a PC exploit is used to infect huge numbers of PCs. It only takes one PC to be infected to help kick-start a process whereby this infection spreads across networks within an organization and, eventually, across the world. This allows hackers to execute the following tasks:

  • Malicious software can be downloaded to PCs without the user’s knowledge
  • Vast amounts of sensitive data can easily be recorded and transmitted to remote locations
  • Ransomware can be used to encrypt data and extort payment in return for the un-encrypted data

How Do You Protect Yourself Against Exploits?

Exploits, of course, are the result of vulnerabilities that are already present on your PCs. Therefore, exploits are down to failures by developers and manufacturers in the design and testing phases of their products. As a result, once an exploit has been identified, any decent developer should work on remedying this exploit by producing a security patch. This patch can be installed on any vulnerable PC to effectively seal the hole in your security gate and keep any hackers out.

Final Thoughts

Exploits can cause major disruption to your organization very quickly due to the ease of access that they gift to hackers. Protecting your organization from these exploits, therefore, is vital to keep your PCs online and productive. Time and knowledge are important commodities when it comes to protecting against exploits, so make sure you remain up to date with not just the latest software patches, but also any breaking news on emerging exploits.

Hacking the Internet of Things For a Few Dollars

The Internet of Things (IoT) has many security concerns, but perhaps one of the most pressing worries is that IoT devices can be easily hacked for just a few dollars.

A group of elite hackers have recently demonstrated the ease with which a hardware hack can be unleashed to take control of IoT devices. All they require to carry out the hack is an SD card reader, the ability to solder and a length of wire – all in all, this should come to around $10. And once they’ve taken control of the device they can not only exploit any data on there, but also use it as a stepping stone to get further into the network it’s on.

With the number of IoT devices expected to hit the 20 billion mark by 2020, the risk of attacks on these devices is only going to get greater and greater. And, for a business, where nearly every employee will have access to an IoT device, perhaps it’s time to get acquainted with this low cost and easy to deploy attack.

Hacking on a Budget

The hack in question is a flash memory attack and, as such, targets IoT devices which have a flash memory – in particular a form of memory known as eMMC flash. It’s likely that you’ve never heard of eMMC flash, but it’s built into a wide range of devices such as smart TVs, cell phones, tablets and even refrigerators. Just think about how many of those devices are in your organization and connected to your network – that’s right, it’s pretty scary. What, though, is this $10 hack?

Well, the hackers – who go under the group name of exploitee.rs – have revealed that they can gain read/write access to devices by taking a flash memory card and soldering wires to five specific places:

  1. Data line
  2. Clock line
  3. Command line
  4. Power line
  5. Ground

This access allows the hackers to start stealing data and to issue commands to the device before taking complete control of it. Once the flash memory card in question is put into an SD card reader, it can then be connected to a PC to glean complete copies of that device’s data inventory. And it’s at this point that the hackers are able to identify zero-day vulnerabilities in the device, vulnerabilities which can be applied to that specific device and any other unit of the same product.

With this information to hand, the hackers are then empowered to launch remote attacks against said device and, potentially, use these infiltrated devices to gain access to the networks they’re connected to. And all of this is possible because hardware manufacturers fail to secure flash memory on their devices, they’re only concerned with creating a front line defense with nothing behind it.

Managing IoT Security Concerns

Hardware manufacturers are slightly off the pace as demonstrated by this budget hack, so for the consumer it’s particularly troubling. As ever, the best advice is to install patches and firmware upgrades as soon as possible. However, when a hardware vulnerability is found it means that it has the potential to leave huge numbers of the same devices – if not all of them – at the risk of being hacked. Therefore, identifying the form of flash memory present in devices may become a major buying point for consumers.

Computers for Classrooms Donation Program

Re-purposing old computers as a learning tool is a project close to our hearts here at Ophtek. Learn how the WCE project helps support the less privileged.

Our ethos of helping to repurpose computers for underprivileged schools and families through our Computers for Classrooms donation program has just gotten better.  We’ve recently donated 35 computers and 16 LCD monitors to the World Computer Exchange, a non-profit organisation with a newly opened chapter in Silicon Valley. There are many benefits to re-purposing old computers as you may have seen through our Computers 4 Classrooms donation program.  Here’s a recap of the benefits of reusing old computers:

Why donate old computers?

  • Greener for the environment– keeps computers out of landfills and reduces toxic waste emitted when they’re incinerated and crushed.
  • Considers worker’s well being– reduces the need for workers to be exposed to chemicals.
  • A valuable tool for the underprivileged– gives those without access to a computer the opportunity to use a computer. For instance families and schools who may lack funds to purchase computer equipment and for children in third world countries.

How does the World Computer Exchange Help Those in Need?

WCE will pre-load free open source educational software onto old computers.  They then ship the ready to be used computers and any new equipment to various underprivileged groups who sign up to partner with them. For instance, this can be schools, libraries, NGOs, orphanages, youth centers, government institutions, learning academies, universities and so forth.

 

Ophtek_Donation

The aim is to provide computer access in public settings to young adults, up to the age of 24, who are members of underprivileged groups in developing countries. This helps keep running costs low, such as Internet use in public educational establishments.

Donated Computer shipments are sent in containers which hold up 250 to 500 computers to help reduce shipment fees.  If less computers are required by a single organization in need, then containers are arranged to be shared when more than one partner within the same nation requests a shipment. The more partners who request a shared container to their country, the less number of computers available to each individual partner.

The donated computers are intended to be used in public facilities and aren’t to be resold.

So far, WCE has helped install 3,050 computer labs, shipped computers to 43 developing countries of which 3.8 million underprivileged youths have connected to in order to benefit and learn.

For organizations that do not have access to the internet, WCE sets up offline content so the computers can still be put to good educational use.
