Ransomware has now become a big problem for many people and businesses. It can lock up your files and make you pay money to get them back. This article will show how businesses can protect themselves from ransomware, minimise ransomware damage and what to do in case of an attack.
What is Ransomware?
Ransomware is a type of bad software that penetrates your computer, locks up your files, and then asks you to pay money to unlock them. This can be very intimidating and costly.
How does ransomware work?
Ransomware usually arrives through email or bad websites and spreads through networks. Once it’s in, it starts locking up your files with strong codes. Then, you will 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. A key is somewhat 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 to 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 100% sure they’re safe.
Back up your files
Copy your most important files and store them in a different location other than your primary computer. That way, if ransomware locks your files, you’ll still have copies.
What do you do if you get ransomware?
So you think you have ransomware? Don’t panic. Here’s what to do:
Disconnect from the network
Immediately disconnect your computer from the internet. This may 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 and report it to your country’s cybersecurity centre. They can help use the info to stop future attacks and minimise ransomware damage.
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. Provide access only to those needed to perform the job. This may limit how far ransomware can spread.
Have a plan ready
Have a strategy in place in case you become a target of ransomware. Exercise it. Preparation will make you swift, and thereby contain the damage.
How is ransomware evolving?
Ransomware is getting newer tricks all the time. Watch for this:
Attacks on phones and tablets
Now, ransomware could 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 bad guys then threaten to share your private information if you don’t pay, making the attack even worse.
Attacks on cloud services
Many people are migrating to the cloud to store data, and ransomware targets those services, too. Ensure your cloud accounts are secure with MFA.
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 stay ready.
