Ransomware has become a big problem for many people and businesses. Ransomware is malware that cyber criminals use to lock up your files and make you pay money to get them back. Fortunately, the PCS team is here to show you how to protect yourself from ransomware and what to do in case of an attack.
What is Ransomware?
As we briefly touched on above, ransomware is malicious software designed to penetrate your computer, lock up your files, and block your access to your information until you pay money to unlock it. A ransomware attack can be both scary and costly.
How does ransomware work?
Ransomware usually comes through email or harmful websites but can also spread through networks. Once it’s in, it locks up your files with strong codes. Shortly after, you see a message asking for money.
How does Encryption Work?
Encryption uses algorithms and keys. An algorithm is a set of rules for solving problems, and a key is like a password that unlocks the secret message.
How can you prevent ransomware attacks?
There are many ways to stop ransomware before it hurts you. Here are some key steps:
Keep your software up to date.
Always keep your computer and programs up to date. Updates often fix problems that ransomware uses to get in.
Use good antivirus software.
Get strong antivirus software. Keep it turned on and updated, as it can detect many kinds of ransomware.
Be careful with emails.
Don’t open emails from people you don’t know. Don’t click links or download files unless you are sure they’re safe.
Back up your files.
Copy your most important files and store them on something other than your primary computer. Even if ransomware locks your files, you’ll still have copies.
What do you do if you get ransomware?
So, do you think you have ransomware? Don’t panic. Here’s what to do:
Disconnect from the network.
Immediately disconnect your computer from the internet, as this can prevent the ransomware from spreading or worsening.
Don’t pay the ransom.
Experts say you shouldn’t pay. There’s no guarantee you’ll get your files back. Plus, paying encourages more attacks.
Report the attack.
Tell the police about the attack. Also, report it to your country’s cyber security center. They can help and use the info to stop future attacks.
Use your backups.
If you have backups, you can restore your files from them. After all, that is what backups are for.
How can businesses protect themselves?
Businesses will want to take a few additional steps to remain safe. Here are some suggestions:
Train your employees.
Train your employees about ransomware. Give them examples of what to watch out for and what to do if they encounter something suspicious.
Limit access to key files.
Not everyone needs access to every file. By limiting access to those required to perform the job, ransomware becomes more likely to be contained.
Have a plan ready.
Have a strategy in place if you become a target of ransomware. Exercise it. Preparation will allow you to act swiftly and mitigate and contain the damages.
How is ransomware evolving?
Ransomware is getting newer tricks all the time. Watch for this:
Attacks on phones and tablets.
Now, ransomware can attack not only computers but also phones and tablets. Be wary of all your devices.
Double extortion.
Some ransomware now steals your data before locking it. The cybercriminals then threaten to share your private information if you don’t pay, which makes the attack even worse.
Attacks on cloud services.
Many people are migrating to the cloud to store data. Ransomware has started targeting those services, too. Ensure your cloud accounts are secure.
Stay Safe and Prepared.
Ransomware is a serious threat, but you can protect yourself by keeping your software updated, being careful online, and always having backups. If you run a business, train your team and have a solid plan. Stay alert and ready.
Do not try to face ransomware on your own. Don’t hesitate to contact the experts at PCS if you need any help with ransomware or have additional questions.
