What Our Clients Say

  • Saved my WEDDING!
    Residential Client

    This past year I have been planning my wedding, and I have a ton of spreadsheets and documents on my computer pertaining to the “big day”.  I saved everything on an external hard drive just in case. One day I went to get one of the documents off of the hard drive and of course there were no documents in the file. My computer is very old so I have worried about it crashing. I have no clue where to take it to find out what went wrong. I was telling my cousin Steve Turner about it and he suggested Decatur Computers. I took it in, I was only there for about 10 minutes, they had great customer service, said that they would call me in a few days to let me know what they were able to do. I got a call that week, they not only retrieved everything on the hard drive but they also increased the speed of my computer so we were able to wait a bit longer to buy a new one. I would definitely recommend anyone to Decatur computers.

  • These guys do a great job!
    Residential Client

    "These guys do a great job! I took my computer in to be updated and they not only did that but they got rid of all the bugs and viruses and it runs much faster. Then when I got home with the upgrade my printer wouldn’t connect. I called them up and they connected to my computer from their location and within half hour they had me back in service!  It was also kind of funny watching them move the mouse and different things going on the screen while I was sitting here not moving a thing. :)"

There Isn’t Much that Is More Devastating than Ransomware

Today’s blog will help you implement measures to keep your business safe from the threat of ransomware. You will gain the foundational knowledge to help you understand this threat, how it spreads, and what you can do to stop it.

What is Ransomware?

Ransomware is a malware that encrypts the files on a computer or device, locking them down so they are essentially useless for the user. Hackers demand a payment in exchange for the safe return of the files. Recent ransomware attacks have demanded massive payments that are impossible to budget for, and these payments are requested in the form of Bitcoin or other cryptocurrencies. Once payment is received, hackers claim that they will hand over the decryption key, giving organizations the ability to decrypt their data.

Businesses should not rely on the goodwill of hackers to get their data back following a ransomware attack, though. It is recommended that you do not pay the ransom for a couple of reasons. For one, who can guarantee that the hacker will return your data to you? What’s stopping them from just taking your money and your dignity along with it? The other issue is that paying up in the face of a ransomware attack is funding further attacks, and it also shows the world that ransomware works, fueling even more attacks in the future.

While we never recommend paying the ransom, it might seem like the only viable choice to get back in action following such an incident. This is especially true in more recent ransomware cases where hackers are also threatening to release encrypted data if the victim refuses to pay the ransom. This puts businesses in a difficult situation; do they risk the security of their data as well as the fines that come from the failure to properly protect it, or do they pay the ransom? It’s a lose-lose situation and one that is entirely preventable with enough precautions.

How Can You Stop It?

Ransomware spreads from system to system in much the same way that normal malware does: through downloading infected files or attachments, clicking on the wrong link while going about your business, or through phishing or social engineering attacks designed to trick users. Hackers can also leverage weaknesses in your network security to install ransomware on devices. Ransomware is certainly a bit different from your typical malware, but at the end of the day, the same tactics used against other threats should work against ransomware. Proactive maintenance, data backups and disaster recovery, security solutions, and proper training for your users can all compound and work to protect your network security from threats of all kinds.

Let Us Help!

It’s not possible to guarantee that your organization will never suffer from a network security disaster, but if you take the appropriate actions now, you will find that the peace of mind that comes from knowing you have done all you can to protect your business might be enough. Decatur Computers Inc. can help your organization secure its network and protect its assets. To learn more, reach out to us at 217-475-0226.

New Report Finds that A Third of Employees Will Fall for Phishing Scams

A study performed by KnowBe4 found that one in three untrained employees were likely to fall for some type of phishing attack or social engineering tactic. The report analyzed businesses to assign what they call a “phish-prone percentage,” or PPP. The average number they found for employees likely to fall for phishing attacks, 31.4%, is actually a bit on the lower end of the spectrum, with some large organizations exceeding the 50% marker.

We suppose this makes sense—the more employees an organization hires, the more points of entry for anyone attempting phishing schemes. Still, this represents a massive threat to all companies. After all, it only takes one or two instances of security breaches to create considerable challenges for your business moving forward.

The key to keep in mind here is the word “untrained,” as in those who have not been trained on how to properly address cybersecurity issues. In those who have gone through a rigorous training process, the likelihood of them falling victim to phishing attacks fell dramatically. KnowBe4 conducted a 90-day training session for the same organizations and found that the number had reduced significantly with just this short amount of training to 16.4%. After one full year of training, the results were even more promising at 4.3%, with the highest rates being for organizations with more than 1,000 employees at 5.9%.

Compared to the previous numbers, we’ll take these results any day. It just goes to show that proper training can make a world of difference for employees, especially as it pertains to cybersecurity. After all, cybersecurity is a multifaceted field, and one needs knowledge of various best practices and a solid understanding of specific threats in order to avoid them. All that said, it is difficult to say that you can help your employees avoid becoming the target of phishing scams. More likely than not, they will encounter a phishing attack of some sort during their employment with your business. How they respond to it is going to be the determining factor for whether or not it becomes a problem for them and for your organization.

We recommend that all businesses take a two-pronged approach to cybersecurity. The first is to implement powerful cybersecurity measures that can keep threats from exposing themselves to your employees. Even the best solutions will not prevent all cybersecurity threats from making themselves known, but they will eliminate the vast majority of threats, reducing the opportunities for your employees to make mistakes with their response.

The second approach, as you may have already guessed, is to provide comprehensive security training for your employees. This is not a one-and-done thing that only happens when they are hired; rather, your security training should be a regular occurrence and one that builds an understanding of cybersecurity best practices and the consequences for not sticking to them. And above all else, it is crucial that you tell your employees that security issues must be brought to your attention immediately. They should not be sweeping issues under the rug and forgetting about them. This is how minor issues become larger problems, and in cybersecurity, these problems matter more than anything else.
