CryptoLocker Ransomware
The CryptoLocker ransomware was first seen in the wild in September 2013. It is a variant of the previous ransomware known as CryptorBit. The biggest difference between these two types of malware is that with CryptoLocker, the attackers use a public/private key pair to encrypt the victim’s files. This means that even if the encryption key is obtained, it cannot be used to decrypt the files without also having the private key, which is only known by the attacker.
Once a system is infected with CryptoLocker, it will scan all drives for certain file types and encrypt them using AES-128 encryption. The ransom note will then be displayed, instructing the user on how to pay the ransom to obtain the private key and decrypt their files. Payment is usually demanded in Bitcoin, although other methods such as MoneyPak have been used as well.
CryptoLocker has been quite successful, netting its creators millions of dollars in ransom payments.
However, there are some ways to protect yourself from this type of malware.
- First and foremost, always have good backups! This way if your system does get infected, you can simply restore your files from backup instead of paying the ransom.
- Secondly, be very careful about what emails you open and what attachments you click on. If you’re not expecting an email with an attachment from someone, don’t open it! Attackers often use phishing emails as a way to spread malware like this.
- Finally, make sure you have good antivirus software installed and keep it up to date.
What was the effect of CryptoLocker?
When CryptoLocker was first unleashed in 2013, it quickly became one of the most feared forms of malware. This CryptoLocker ransomware not only encrypted a victim’s files but also demanded a ransom be paid to decrypt them. Many people succumbed to the demands, as they had no other choice if they wanted to regain access to their important files. However, even after paying the ransom, there were no guarantees that the files would be successfully decrypted.
The effects of CryptoLocker were far-reaching and caused a lot of damage. Not only did individuals lose access to their files, but businesses suffered as well. Productivity came to a halt as employees’ work was inaccessible and company data was lost. The cost of dealing with this malware was estimated to be around $3 billion.

This had a serious impact on productivity, as businesses were forced to deal with employees’ inaccessibility and data loss. The total cost of CryptoLocker was estimated to be around $3 billion.
Thankfully, law enforcement was able to take down the network that distributed CryptoLocker and create a tool that could decrypt files for free. However, by then the damage had already been done and many people were left feeling frustrated and angry at the loss of their valuable data.

How does CryptoLocker infect your computer?
CryptoLocker is a type of malware that encrypts your files and holds them for ransom. It can spread through email attachments, drive-by downloads, and USB devices. Once it’s on your computer, it will start encrypting your files, making them inaccessible. To get your files back, you’ll have to pay a ransom fee. CryptoLocker is a serious threat to your data and should be avoided at all costs.
There are a few ways that CryptoLocker can make its way onto your computer.
- One way is through email attachments. Cybercriminals will send out mass emails with an infected attachment. When the attachment is opened, it will launch the malware on your computer.
- Cybercriminals will often send out phishing emails that look like they’re from a legitimate source. The email will contain an infected attachment or link. When you click on the attachment or link, it will download and launch the CryptoLocker malware onto your computer.
- Another way that CryptoLocker can infect your computer is through drive-by downloads. This happens when you visit an infected website and the malware is automatically downloaded and installed onto your computer. The website may not look suspicious, but it’s been hacked and contains malicious code that will download the CryptoLocker malware onto your computer.
- Cybercriminals will sometimes use USB devices to spread the CryptoLocker malware. They may infect a USB drive with the malware and then leave it in a public place for someone to find. When the USB drive is plugged into a computer, the malware will automatically launch and start encrypting files.
- And, CryptoLocker can be spread through USB devices. If you insert an infected USB drive into your computer, the malware will launch and start encrypting your files.
