In our last blog, we explained what ransomware is, and why it can be an especially troublesome virus. Today, let’s look at what you can do to avoid falling victim.
Prevention is the best cure. Follow standard “data hygiene” principles that you probably hear about all of the time. Update your OS, software, and apps whenever a new release or patch is released. Do this ASAP. Some patches may be released solely as a result of the discovery of a vulnerability. Watch out for phishing scams. If anything looks “off” about an email, don’t open it. And never open links you aren’t totally sure of. If unsure, email back to the sender to verify they actually sent you a link. Unfortunately, human error is one of the biggest problems for data security. Employees unwittingly open links received via email or download information from insecure websites.
Beyond prevention, the most important thing you can do to make sure your data cannot be held ransom is strictly adhering to a regimen of backups. Routinely backup your data. However, with ransomware, even backups may not be foolproof. If your data has been infected and you are unaware of it, or the backup is not segregated from your network, your backups may also be corrupted. Given the severe consequences of a ransomware attack, consider having a security evaluation done by a managed service provider who will have the security expertise to advise on the best backup protocols for your situation. Ransomware presents some unique challenges that require more sophisticated data protection protocols. Contact a managed service provider for a complete security evaluation.
The daily reports of cybercrime are important reminders about the need to protect your business from malicious behavior that could threaten the success of your business. There are so many different things that can attack your computer, steal your data, and wreck your day. One of the most troublesome has been the development of ransomware. (FYI. Ransomware isn’t actually all that new– some version has been around for decades) Ransomware is a type of computer virus that takes your data hostage and like any kidnapping scheme, demands money for the release of your data.
Why is ransomware so nasty? Because it steals the most important thing your business possesses. Data. Worse, once infected there isn’t generally a way out. No one can “disinfect” your machine. You aren’t going to be able to call in IT support to solve the problem. Basically, you have three options.
Pay the ransom. This payment is usually via credit card or bitcoin (a digital currency). Some ransomware viruses even provide help lines if you’re having trouble. Of course there are no guarantees your will get access to your data–these are thieves you’re dealing with.
Don’t pay and lose your data – This has its obvious downsides, unless…
You have a safe, clean backup. In that case, you are stuck with the nuisance of restoring your data with the backup, but you aren’t out any money. However, this comes with a caveat: your backups have to be clean. The problem with ransomware viruses is that just making backups may not be sufficient to protect your data, as the backups can be infected also. In the next blog, we will address your need to add an additional layer of protection to handle ransomware attacks.
This cyberattack scheme hasn’t garnered nearly as much attention as the usual “break-in-and-steal-data-to-sell-on-the-Internet version,” but it can be even more debilitating. Ransomware attacks have begun appearing in the last few years and its practitioners are so polished that in few cases they even have minicall centers to handle your payments and questions.
So what is ransomware? Ransomware stops you from using your PC, files or programs. The business model is as old as the earliest kidnapping. They hold your data, software, or entire PC hostage until you pay them a ransom to get it back. What happens is that you suddenly have no access to a program or file and a screen appears announcing your files are encrypted and that you need to pay (usually in bitcoins) to regain access. There may even be a Doomsday-style clock counting down the time you have to pay or lose everything.
Interestingly, one of the more common “market segments” being targeted in the US has been public safety. Police department data is held hostage, and in many cases, they have given up and paid the ransom. They had little choice. They aren’t the only ones. A hospital in Southern california also fell prey, as did one in Texas.
Ransomware can be especially insidious because backups may not offer complete protection against these criminals. Such new schemes illustrate why you need to have a professional security service that can keep you up to date on the latest criminal activities in the cyber world.
