What is Ransomware?
Ransomware is a type of malware that encrypts the hard drive or an individual's sensitive information and then demands a ransom from the victim. In most cases, this ransom is paid in Bitcoin so as to not be traced by law enforcement.
How Does Ransomware Spread?
Ransomware spreads mainly through the use of phishing emails. These emails try and trick people into downloading and opening a malicious attachment, which usually appears as an email from a trusted source such as your bank. It may seem like an innocent email asking that you verify or change your account information, but it's actually the first step that ransomware takes to get what it wants: your sensitive information.
A common example of how ransomware spreads is through clicking on links in spam emails. This can lead you to websites that have not been updated with security updates, which means they'll be vulnerable to exploits from ransomware-type programs. Once on these websites, malware can infect your computer without any warning from you.
Another way that ransomware spreads is through malicious downloads. Many people have fallen victim to these. Not only are they easily accessible, but they're also free. When downloading files from the Internet, especially if they are not from a reputable source, it's best to be careful about what you install on your computer. It may seem enticing to download a free photo editor or media player, but it could be installing ransomware on your computer without you even knowing!
How Does Mrdc Ransomware Work?
It works by first locking the operating system with a strong encryption. Then, it creates a secondary boot sector that steals important data from the victim's computer and encrypts them. The Mrdc Ransomware then adds a new file that contains all of the encrypted information named according to its own ID. This ID is created from random numbers and letters. It also makes sure that the ransom note contains an indicator of whether you have been infected or not, so it can be sent to your email address should you not comply with its demands.
How to Remove Mrdc Ransomware
1. Restart your system.
2. Boot it in Safe Mode with Networking; this will disable the ransomware temporarily and allow you to get some of your data back since it's not encrypted - however, you need to know what files you want to recover first before doing this
3. Run a malware scanner (e.g., Malwarebytes Anti-Malware) and remove any infections that are detected
4. Restore your files from a backup
5. If you're unable to restore your files, try booting the computer in Safe Mode with Command Prompt or Recovery Mode so that you can delete or rename the encrypted file, but only if you are confident enough with using the Command Prompt
6. Once done, run another malware scanner to ensure no traces of it are left.
How to Protect My Computer From Ransomware
A few things that you can do to protect your computer from ransomware:
1. Using a good, up-to-date antivirus and anti-malware software and keep it updated to date with regular scans
2. Back up all of your important files so they are not so easily attainable by ransomware
3. Have a recovery plan in place - this is an excellent option if you download something off the web and it ends up being ransomware
4. Use caution when clicking links or opening attachments in emails and be wary of the sites you visit online
