Whoopsie is a ransomware which compromises data on the computer and asks to pay €50 as a ransom.

Whoopsie is a ransomware-type cyber threat which is designed to encrypt data using AES cryptography[1]. At this point, the user is no longer able to use the encoded information with .whoopsie extension, unless it is decrypted with a unique key. Criminals demand to pay €50 in Bitcoins for the decryption software. According to the experts, this infection is created by an attacker located in Germany.

Name Whoopsie
Type Ransomware
Danger level High
Cryptography Advanced Encryption Standard (AES)
File extension .whoopsie
Amount of the ransom €50 in BTC
Decryptable No. But you can find alternative ways how to recover data at the end of this article.
Removal The safest way to uninstall Whoopsie ransomware is with Reimage

Once Whoopsie ransomware infects the system, it starts encrypting the most widely used files on the system by employing AES algorithms. Afterward, the encoded files are appended with .whoopsie extension and become unusable. The victim merely receives a pop-up window named as Whoopsie which serves as the ransom note.

People are informed about Whoopsie virus infection and the following information:

Do NOT close this Window! (otherwise your Files are gone for even and cant be recovered!)

Your files has been encrypted with Advanced Encryption Standard (AES) and can't be decrypted without a specific key (in this case a ransom generated String)

How to get the key?
Its easier than it seams! Just pay a small fee of 50€ in BTC to {paymentadress} and you will get your decryption key

Unfortunately, there are no guarantees that you will receive Whoopsie ransomware decryptor after paying the so-called small fee. In fact, despite how insignificant the amount of the ransom might seem, attackers can force you to spend more and more after you contact them[2]

Instead of agreeing to the rules of the criminals, we advise you remove Whoopsie ransomware after the infection. You should get help from a professional security tool such as Reimage. Keep in mind that you shouldn't try to eliminate this dangerous cyber threat on your own or you might damage your PC even more.

After Whoopsie virus removal, you will be able to try alternative ways to get back the access to your data. All of them are presented at the end of this article. Although, they are effective only once the ransomware is uninstalled from the infected system.

Distribution: spam emails, peer-to-peer (P2P) networks, and malvertising

Since ransomware-type infections are almost the most dangerous ones, criminals are highly interested in distributing them worldwide. For that, they employ not one, but multiple spread techniques to increase the infection rates of Whoopsie ransomware and similar threats. According to the experts from UK[3], today the most popular distribution method is malicious email attachments.

This method is often recognized as malspam campaigns which are designed to distribute legitimate-looking emails with an infected attachment inside. Once the user clicks on the file, it drops the payload of the ransomware and infects the system. Thus, people should NEVER open letters from suspicious users or companies.

Furthermore, Whoopsie ransomware can enter the system from the shady peer-to-peer (P2P) file-sharing site or malicious ads on websites. Our experts recommend you to download programs only from verified authors and distributors. Additionally, monitor your online activity and refrain from clicking on commercial content to avoid Whoopsie ransomware.
