Ransomware: What are some examples of these attacks?
As we know [ransomware] is a type of malware that encrypts files on your computer and then demands payment to decrypt them. This usually happens when you open an infected email attachment, click on a link or visit a malicious website. The ransomware will lock up your files, preventing you from accessing them until you pay the ransom. It’s important to note that this attack does not affect all computers at once; it only affects one computer at a time. Once the ransomware has encrypted your files, it may also delete any backups you have made of those files.
Here are some popular examples of ransomware attacks
CryptoLocker – This is one of the most popular types of ransomware viruses. They usually lock users out of their computers unless they pay a ransom fee. CryptoLocker was first discovered in September 2013 and since then it has become very widespread.
Sofacy – Sofacy is another type of ransomware virus that locks users out of their PCs. However, unlike CryptoLocker, Sofacy only demands $300 per machine instead of $500.
Locky – Locky is yet another type of ransomware virus. It locks users out of their computers, forces them to watch videos, and displays messages demanding payment. Locky has been around since 2014 and it has spread rapidly across the globe.
Petya/NotPetya – Petya/Notpetya is a variant of the WannaCry ransomware virus. Unlike WannaCry, however, Petya/NotPetya doesn’t affect Windows XP machines. Instead, it targets Windows 7 and 8 systems.
Wannacry – Wannacry is a ransomware virus that affects Microsoft Windows operating systems. It spreads via malicious attachments sent through email. Once it infects a user’s computer, it starts encrypting data and displaying messages demanding a ransom fee.
Wiper – Wiper is a ransomware virus that deletes all the files on a user’s hard drive. It is extremely dangerous because once it gets into a user’s system, it may delete everything including important documents, photos, and even personal information.
NotPetya – NotPetya is a variant form of the WannaCry virus. It differs from WannaCry in that it only affects older versions of Microsoft Windows (Windows XP).
Cryptowall – Cryptowall is a new type of ransomware virus that encrypts files on a user‘s computer. It is different from other types of ransomware viruses because it doesn’t display any messages asking for a ransom. Instead, it just locks users out of their systems.
Bad Rabbit – Bad Rabbit is an advanced version of the Locky ransomware virus. It can steal sensitive information such as credit card numbers, social security numbers, and passwords.
Have you ever received an email from someone claiming to be from FedEx or UPS? If yes, then you might want to check out this article. This type of scam has become very common lately.
The CryptoLocker virus was created by the notorious cybercriminal group called ‘Shadow Brokers’. They released a huge trove of data stolen from the NSA. The hackers claimed that they had obtained the information from the U.S. government.
This ransomware was designed to encrypt files on infected computers. Once encrypted, the user would receive a ransom note demanding payment to decrypt their files.
History of CryptoLocker Ransomware
CryptoLocker started spreading back in September 2013. Since then it has become very popular. It has affected more than 500,000 computers worldwide.
In April 2015, the FBI issued a warning about the threat posed by CryptoLocker. It said that the virus could lock up your entire PC and demand a ransom.
In June 2016, the FBI arrested three men who were responsible for creating the CryptoLocker virus. One of the suspects was named Dmitry Tarabukin. He was accused of selling access to the source code of the virus.
In August 2017, the Shadow Brokers published a massive collection of data stolen from the National Security Agency. Amongst the leaked data was the source code of the CryptoLocker virus which they used to create the ransomware.
How do we get infected with the CryptoLocker virus?
CryptoLocker virus is one of the most dangerous viruses which attacks users’ computers. There are various ways through which you can get infected with this virus. Some of them are mentioned below.
Downloading Malicious Software
Some websites offer software downloads without verifying whether the downloaded file contains harmful components. As soon as you click on such links, you could be infected with malware.
Opening Email Attachments
Some emails contain malicious attachments. These attachments usually come disguised as images or videos. When opened, these attachments automatically execute the code contained within them.
Phishing scams are also another way through which people fall prey to this infection. In phishing scams, criminals send fake messages to trick users into revealing personal details like credit card numbers, bank account details, etc.
How Does CryptoLocker Work?
When people open emails containing links to malicious websites, they are often tricked into downloading malware onto their computers. When the victim opens the attachment, the file will automatically start running on their computer.
Once the virus is installed, it will begin searching for certain files on the user’s computer. These include:
– Other files
When it finds these files, it encrypts them using a special algorithm. Then, it displays a message saying that the files have been locked due to copyright infringement.
It also creates a folder with the same name as the original file. Inside this folder, there will be another file labeled “Decryptor”.
The decryption key is stored inside this second file. However, if the user tries to run the program, it will crash.
