Hackers use cryptojacking to mine cryptocurrencies, and this process can cause PCs to run below optimal speeds.  If you have a relatively new computer but are experiencing performance problems after clicking a link or visiting a website, you might be a victim of cryptojacking. Here’s what to do. Hijacked hardware Instead of paying for computing power themselves, hackers opt to secretly use thousands of compromised computers to generate cryptocurrency. They gain control of a victim’s PC by using phishing emails to lure them into clicking on a link, which then runs malicious cryptomining programs on the computer. Any cryptocurrency produced then gets delivered to the hackers’ private server. But wait, there’s a more insidious tactic hackers use: infecting websites with ads and plugins that run cryptojacking code. By doing so, any visitor who loads the web page instantly gets infected with the malware, which sends their computer’s processor into overdrive as it tries to generate cryptocurrency. If there’s a silver lining here, it’s that cryptojacking software won’t compromise your data unlike most malware do. However, it will hijack your hardware’s processing power, so you’ll experience decreased PC performance while your electricity bills increase. Surge in cryptojacking The biggest reason why cryptojacking is becoming so popular is that it’s a low-risk, high-reward scheme. Instead of extorting money directly from the victim, hackers can secretly generate digital currencies without the victim knowing. And even if it’s detected, it’s almost impossible to track down who initiated the attack. Moreover, since nothing was actually “stolen” (other than a portion of computing power), victims have little incentive to apprehend the culprit. Cryptojacking is also a cheap investment. For as little as $30, anyone can purchase a cryptojacking kit from the dark web to force other computers to generate Bitcoin or Monero for them. And while it’s difficult to tell how much exactly are hackers earning by cryptojacking, we can only surmise that it’s more than the initial $30. Because of these reasons, there’s a good chance that this type of attack will be as popular as ransomware was in 2017. According to several reports, even sites like The Pirate Bay, Openload, and OnlineVideoConverter are allegedly using cryptojacking exploits to diversify their revenue streams. Prevention and response Prevention is always better than cure, so include cryptojacking in your monthly security training sessions. If employees practice extra caution in dealing with unsolicited emails and suspicious links, then hackers will have no way into your systems. Using ad-blocker or anti-cryptomining extensions on web browsers is also a great way to stay protected. Beyond prevention, network monitoring solutions should also be used to detect any unusual computer behavior. For example, if you notice a significant number of PCs running slower than usual, assume that cryptojacking is taking place. And once it’s confirmed, advise your staff to close browser tabs and update browser extensions as soon as possible. Because cryptojacking doesn’t steal data, it may seem less threatening than some malware, but in reality, its effects are just as severe — it can incur real power, cooling, and performance costs to your business when several systems are compromised.

Office 365, the cloud-based version of Office, is one of the most popular software suites used by small- to medium-sized businesses (SMBs) today. With an ever-increasing number of companies migrating to this solution, it’s not surprising that many others are considering making the move. However, there’s always a chance of migration failure. Learn how to avoid this by knowing the five most common ways that Office 365 migration can fail. 1. Slow internet connection speeds To avoid this, ask an Office 365 provider like Multi IT & Telephony Solutions to test your existing network connections to ensure that your internet connection can handle the migration and day-to-day operation of Office 365. If not, they should be able to offer you a more efficient solution. Because Office 365 is primarily cloud-based, you are going to need a connection with a solid bandwidth. When migrating your files and system over to Office 365, you will likely need to consume a large quantity of bandwidth. This demand will often be enough to tax most small business lines, resulting in slower internet speeds all around during the process. Employees might struggle to do their jobs properly if they’re reliant on the internet, so it is recommended to do migrations during off hours. Beyond this, Office 365 is most often delivered over an internet connection, rather than in-house servers. This means that the day-to-day demand for bandwidth will increase. If you are already noticing slow speeds and service interruptions before implementing Office 365, you will likely see these issues compounded after implementation. 2. Mailboxes and files are too big While the business versions of Office 365 come with 100 GB of email storage and over 1 TB of file storage per user, getting your emails and files online could take a while, especially if you have users whose inboxes are approaching the storage limit. As a general rule of thumb, larger files will cause the migration of files to take longer. If you don’t prepare for this, then you could see migration affecting work or even causing recurring issues of unavailable data when it’s needed. To avoid this, encourage your staff to archive their email inboxes and either delete or remove emails with large attachments that aren’t necessary. 3. Uninformed users The average Office 365 migration takes around one to three days, depending on the size of the business and the amount of data being carried over. If you start migration without informing users that some files and emails won’t be accessible during this period, or that some systems may not be working, you could end up with employees unable to do their jobs and creating resentment for the new platform. Instead, inform your employees about how the migration will run and what they can expect during the process. Beyond this, you should run training sessions on how to use the new systems to ensure that everyone is briefed before they start to use them. This will increase the overall chance that the platform migration and subsequent use will be successful. Older, less compatible software installed on systems While many versions of Office 365 do come with subscriptions to the latest version of Microsoft Office, there’s built-in support for systems that are running slightly older versions of Office. If your business is using a version older than Office 2010 (e.g., Office 2003), you won’t be able to properly use Office 365. Beyond this, you’ll also need to use the latest version of your internet browser. If you use Chrome or Firefox, this won’t be a problem. However, if you use Internet Explorer, you may run into issues, as Microsoft has already discontinued the program in favour of Microsoft Edge. The good news about Office 365 is that actual systems requirements are low, so almost every business will be able to integrate it. We recommend that in order to be able to use all of Office 365's features, ask your provider to ensure that your software and systems are compatible with it. 5. DIY migrations On paper, migrating to Office 365 is a fairly simple and straightforward process. What many companies find when they do the migration themselves is that the process is much more difficult than expected. They come across unexpected issues that require an IT expert to solve. In order to ensure a smooth migration, it’s a good idea to work with an IT provider like us at Multi IT & Telephony Solutions. We can ensure that your systems are ready and the migration is smooth with minimal disruption. Contact us today to learn more.

With the rise of eCommerce and online banking, cyber-crime has evolved. Like criminals who pull smash-and-grab jobs, they go where the money is. However, unlike bank robbers, cyber criminals do their best to avoid detection by letting malware do the work for them. Viruses and ransomware sneak into PCs to quietly steal passwords, financial credentials, and other personal information to be sold on the black market for profit. Not all malware is stealthy though. Here are some telltale signs. Slow computer Are your operating systems and programs taking a while to start up? Is your data bandwidth suspiciously slow? If so, your computer may potentially have a virus. However, just because your PC is running slower than usual doesn’t necessarily mean that it’s infected, as there could be other causes to your computer slowing down. First, check if you’re running out of RAM. For Windows, open task manager (press Ctrl + Shift + Esc) and go to the Performance tab and check how many gigabytes of RAM are used up under the Memory section. For Mac OS users, you can open the Activity Monitor app and, under System Memory, you should be able to find out your RAM usage. Other causes could include lack of space on your hard drive or even damaged hardware. Once you’ve ruled out other possible causes, then malware may have infected your device. Blue screen of death (BSOD) If your PC crashes regularly, it’s usually either a technical problem with your system or a malware infection. You might not have installed the latest drivers for your device or the programs you’re running could possibly be incompatible with your hardware. If none of these problems are apparent in your PC, then a virus could be clashing with other programs and causing your crashes.To check what caused your last BSOD, go to Control Panel > System and Security > Administrative Tools > Event Viewer and select Windows Logs. Those marked with “error” are your recorded crashes. For troubleshooting solutions, consult forums or your IT department to figure out what to do next. Lack of storage space There are several types of malware that can manipulate and corrupt the files saved on your computer. Most tend to fill up your hard drive with suspicious files. Ransomware, for example, is a notorious type of malware that denies you access to your data until you pay a so-called ransom. There are more aggressive forms of ransomware, like NotPetya, known for exploiting security holes to infect computers without needing to trick users. If you find any unknown programs that you have never installed before, notify IT personnel in person immediately (do not email them) and have them handle the situation for you. Your device might not be the only one in your network that is infected with suspicious programs. Suspicious modem and hard drive activity Combined with the other warning signs, if your hard disk is working excessively while no programs are currently running or if you notice that your external modem is always lit, then you should scan your computer for viruses. Pop-ups, websites, toolbars, and other unwanted programs Pop-ups come from clicking on suspicious pages, such as those where users are asked to answer survey questions to access a website’s service or install free applications. While they’re inherently harmless, they could be downright annoying. Refrain from clicking pop-up pages and just close them instead. Run malware scans and update your browsers. You might think that downloading free applications is harmless, but the installation process can inject malware into your device. When you’re installing a program from the internet or even app stores, it’s easy to just skim over the terms and conditions page and repeatedly press next. This is where they get you. In the process of skipping over certain installation steps, you might have agreed to accepting a new default browser and opening unwanted websites and other programs filled with viruses. Be cautious when downloading something for free. You’re sending out spam If your friends are telling you that you’ve been sending them suspicious messages and links over social media or email, you might be a victim of spyware. Warn your friends not to open anything that appears to be spam and make sure to reset your passwords across all your devices and enable multi-factor authentication. Knowing how malicious software affects your computer can help you take the necessary precautions and steps to rectify the situation as soon as possible. Regardless of whether or not your system has experienced these symptoms, it’s always smart to perform regular malware scans to ensure your business is safe.
