Ransomware is a type of malware software where the attacker encrypts the victim’s data, and demands payment for the decryption key. If you are not protected from the effect of ransomware, you may need to pay a ransom for the decryption key from the attacker. Here is more information about ransomware, and some steps you can take to protect yourself from ransomware.
Your best defense is to block the malware before it can infect your PCs or servers. Install an anti-virus program and keep it running whenever your PCs or servers are on. Also, keep the anti-virus program and threat-pattern files up-to-date. The best anti-virus programs periodically and often download a database of newly found virus and malware threats. And, they continually run, monitor and protect the devices on which they are installed
Ransomware, like many malware programs, makes use of vulnerabilities in your operating system and other software to infect your systems. You must regularly ensure that you download and apply updates. Additionally, don’t forget firmware updates to your network infrastructure and IoT devices, which can also help prevent attacks.
Filter .EXE Attachments in Your Email
If your email service provider has the ability to filter attached files by extension, you may wish to deny receipt of emails sent with “.EXE” (executable) files. When you do need to exchange “.EXE” files, and if are denying emails with attached “.EXE” files, you can exchange those as ZIP files, via SFTP or via a cloud service.
Use System Restore
If you have System Restore enabled on your Windows machine, you might be able to take your system back to a last known clean state. However, some newer versions of ransomware have the ability to delete files from System Restore, which means those files will not be there when you try to replace your malware-damaged versions.
The Bottom Line
The best cure for ransomware is prevention. Once you are infected, your options may be limited, expensive and unpleasant. If you find yourself encrypted and without a viable backup, you may be forced to pay the ransom. Doing so depends on the value of your affected data and systems. If your data and systems are sufficiently valuable, paying the ransom may be your only course of action.
