What is Cryptolocker Ransomware?
Cryptolocker ransomware is a harmful malware infection that encrypts the files of the infected user and renders it inaccessible. Cybercriminals create it to take advantage of flaws in a victims ’ computers and request ransom money in exchange for the recovery and decryption of the data they encrypt.
Since so many people have essential documents and files on their devices, those infected with Cryptolocker ransomware are compelled to pay the ransom requested by the cyber criminals in exchange for their data.
The majority of the new forms of this file locker malware are impossible to decrypt on your own, and even professionals are having trouble recovering these encrypted files, which is why most individuals are choosing to pay the attackers for their files.
Being infected with a severe virus like the Cryptolocker ransomware can be extremely damaging to a computer system and its networked devices. It can also migrate from one computer to another via the internet. If a device is infected and linked to a network, the virus can spread to other devices on the same network.
When a computer gets hacked, it’s best to disconnect it from the network as quickly as possible, or at the very least boot it into safe mode with networking.
The Purpose of Cryptolocker Ransomware
A ransomware virus encrypts files on affected systems and demands a ransom payment to unlock them. The ransom is usually paid in Bitcoin or other cryptocurrencies, and the ransomware operators typically claim that the files will not be released until the ransom is paid.
By encrypting vast numbers of files and demanding large ransom payments, the Cryptolocker ransomware perpetrators can make a lot of money. Because the files that are encrypted can be highly valuable in some situations, a hefty ransom can be asked.
After paying the ransom as suggested by the attackers, the victim is given a decryption key that can be used to restore their files.
The decryption key is a one-of-a-kind digital code that decrypts files encrypted by the ransomware virus.
However, in the case of a ransomware infection, a successful ransom transaction and decryption is not always the case. It’s not just right to put your trust in the people who encrypted the data in the first place. Because doing so may have the reverse effect and cause extra damage to your computer, as well as the data being destroyed entirely.
How does Cryptolocker Ransomware spread?
Almost every other sort of computer virus enters a device in the same way. They do not work at first, but after the file is executed, they begin to do their destructive operations.
A person cannot normally receive a malicious file if they are cautious about what they are accessing, whether it is a website or an email.
It is the most extensively utilized and popular method. The intended recipient is tricked into downloading malicious software attached to the attackers’ email. In the attachments, the files are either grouped together or disguised as papers, movies, and voicemails.
Another method is through drive-by downloads, which occur when a user visits an infected website that has been infected with a malicious script that causes a random piece of malware to be downloaded. Once these weaknesses have been exploited, hackers can utilize them to gain unauthorized access to targets’ systems.
Torrent files are also one of the most common ways to receive this infection, as they are utilized by millions of pirates around the world to download pirated movies and music, as well as cracked versions of premium software. Since then, cyber criminals have spread their malicious software through the torrent community.
Torrent files, especially.exe files, are usually contaminated. If you’re downloading from a torrent site, double-check the file extension because it’s common to find that a pirated movie or music in the .exe format is infected with a virus.

Before returning to normal Windows mode, make sure the computing device is safe and malware-free. You don’t want another ransomware attack to occur once you reboot.
Cybercriminals utilize a variety of methods to obtain access to their victims’ devices; individuals who have recently been hacked should ensure that their device’s security is tight to prevent hackers from gaining access again.
Here are a few things to do to keep the computer safe against another ransomware attack or any other dangerous threats.
Use the Controlled Folder Access Feature
Controlled folder access should be used if you’re running Windows 10 or 11. It helps safeguard sensitive data from malicious threats, such as the Cryptolocker ransomware.
Turning it on will limit access to the specified folders to just those applications that have been given permission to open them. Please follow the procedures below to enable controlled folder access unless you already have it enabled.
1 Open the Windows Start Menu and search Windows Security then click the application.
2 Once the Windows Security application shows up, click on Virus & threat protection from one of the options shown.
3 Scroll down and find the Ransomware protection section, then click the Manage ransomware protection as shown.
4 Turn on the Controlled folder access by toggling it On.
5 From the Protected folders button, you can add the folders you want protected and only apps with permission are only allowed to access it.
Although not every file on the computer can be safeguarded, but all valuable files should be retained and placed in a protected folder. Malware like Cryptolocker ransomware won’t be able to infect and encrypt files within a protected folder thanks to the Controlled folder access functionality.
It’s a very helpful feature to have, but you should be cautious about which apps you provide access to protected folders. There may be viruses disguised as genuine programs that could try and take advantage of this, therefore be cautious when giving permission to programs and double-check that they are valid.
Setup OneDrive for File Recovery
One of the most important precautions, according to many computer experts, is to periodically backup your files so that you have a copy in case of a ransomware attack.

Some Internet Safety Tips
- Websites with distinctive domain extensions should be avoided. Domain extensions other than .com, .org, .net, and .edu should be avoided because most infected websites have very distinct TLDs, always check the last section of a domain to make sure you’re on a safe site, unless it’s been reputable for a long time.
- Never download software or programs from unknown sources. This is one of the most popular ways for adware and other malware to infiltrate your computer. Download only from recognized and legal sources. To be secure, avoid torrent downloads and cracked software download sites, as the files will almost always contain viruses.
- One of the most reliable ways to be safe online is to use a firewall. It protects users from potentially hazardous websites by acting as a first line of protection. It keeps intruders out of the user’s network and device. In today’s world, a firewall will protect a user from the risks that lurk on the huge internet.
- Anti-virus software must be kept up to date. These programs should always be updated on a computer since hundreds of new malware threats are produced every day that aim to infect the machine’s weaknesses. Antivirus updates contain the most recent files needed to combat new threats and protect your computer.
- Visit only websites with a secure connection. Since HTTP connections do not encrypt the data they receive, they are not considered secure. Entering personal information like email addresses, phone numbers, and passwords on a website that uses an HTTP connection is hazardous since your information could be stolen. Websites that use HTTPS connections, on the other hand, are more secure because data is encrypted and attackers are less likely to obtain access to information shared within the site.
