This post will tell you what ransomware is and how to Protect Yourself From Ransomware . During the past year, you may have heard the word “ransomware” a lot. A new report says that 21% of all cyberattacks are caused by ransomware. This is a good reason for this. Hackers with business sense use this method all the time because it works and organisations are willing to pay.
But what does that mean for you and your ability to live your life online with confidence? People can avoid ransomware by doing a number of different things. First, though, let’s go over the basics. Ransomware is a type of malware that encrypts the information of a victim and holds it for ransom.
The hacker uses it to encrypt important information about a user or organization so that they can’t get to files, databases, or applications. Then, a ransom is asked for to let people in. It is a growing threat that pays cybercriminals billions of dollars and costs businesses and government agencies a lot of money to fix and fix the damage it causes.
Ways to Protect Yourself From Ransomware
Set up and perform regular backups
A backup is a digital copy of your most important information, like photos, customer information, or financial records, that is saved on an external storage device or in the cloud.
The best way to get your files back after ransomware hits is to use a backup that wasn’t affected. Back up your files on a regular basis to an external device or the cloud. Having peace of mind comes from making backups and making sure they work.
You can back up your devices in a number of ways. For more information, see our tips for backups.
Use anti-virus software
Antivirus software can help stop ransomware from getting on your device, find it, and get rid of it. Make sure your anti-virus software is turned on and that you keep it up to date. The ACSC has put out information about how to choose antivirus software. You might also have an anti-virus programme on your device already. Windows Security is a built-in anti-virus tool that comes with Windows 10 and Windows 11.
No matter what anti-virus programme you choose, you should learn what real warnings look like. Some websites will give you a fake warning to get you to click on a link that could be harmful. If you know how your anti-virus warnings look, you can avoid links that could hurt you.
Turn on multi-factor authentication
Multi-factor authentication (MFA) makes it harder for cybercriminals to get initial access to your device, account, and information by making them go through more security hoops and more authentication layers. This means that the cybercriminal will have to spend more time, effort, and money to get into your device before any ransomware attacks can start.
Before letting someone into an account, MFA usually needs two or more of the following types of authentication:
- something a user knows (PIN, password/passphrase),
- something a user has (smartcard, physical token), or
- something a user is (fingerprint, iris scan).
Regularly update your devices
Cybercriminals can get into your devices by taking advantage of known flaws. Updates improve security so that known flaws can’t be used to break into your system. When asked, you should always update your system and apps. You can also set some devices and apps to update automatically, so you don’t have to do anything.
Read our advice on updates to find out how to update your Windows, iPhone, and Android devices, among other things. Make sure to update your network’s server and any Network Attached Storage (NAS) devices as well. If you don’t know how to update your NAS, look at the manufacturer’s instructions or talk to an IT expert.
FAQ
Can you protect against ransomware?
Before you use a backup to restore files, check it for malware. Ransomware may have gotten into your network over time and copied itself to backups before you found out. Patch backup products regularly so that attackers can’t take advantage of any known flaws they might have.
What is ransomware and how do you protect against it?
Ransomware is a type of malware that is very common and very dangerous. It works by making your files inaccessible by locking or encrypting them. To get access to the files back or to stop data and intellectual property from being leaked or sold online, a ransom is usually asked for.
Can antivirus remove ransomware?
All of your devices, including your PC, Mac, Android, and iPhone, will be free of ransomware if you use a reputable antivirus tool. In fact, the best and easiest way to get rid of ransomware is with strong antivirus software, though this won’t decrypt any files that have already been encrypted.
Is there a way around ransomware?
You can use the antivirus software to delete malicious files by hand or automatically. Malware should only be removed manually by people who are good with computers. If ransomware gets on your computer and encrypts your files, you will need a decryption tool to get back into them.
