What is Whoopsie ransomware? And how does it implement its attack?

Whoopsie ransomware is a new file-encrypting virus that was spotted as of late. According to security experts, it is created by some cyber crooks from Germany. It spreads over the web via a malicious executable file named “Tree.exe”. Once this malicious file finds its way into a targeted computer, it will install Whoopsie ransomware. From there, Whoopsie ransomware will start to implement its attack by first connecting to its remote server controlled by its developers. It then downloads more malicious files that are dropped into system folders. These malicious files are supposedly used to keep the crypto-virus undetected. It also modifies some registry keys in the Windows Registry so that the malware can run on every system boot.
Once these changes are applied, Whoopsie ransomware begins its search for files with specific file types like:
.3dm, .3g2, .3gp, .7zip, .aaf, .accdb, .aep, .aepx, .aet, .ai, .aif, .as, .as3, .asf, .asp, .asx, .avi, .bmp, .c, .class, .cpp, .cs, .csv, .dat, .db, .dbf, .doc, .docb, .docm, .docx, .dot, .dotm, .dotx, .dwg, .dxf, .efx, .eps, .fla, .flv, .gif, .h, .idml, .iff, .indb, .indd, .indl, .indt, .inx, .jar, .java, .jpeg, .jpg, .js, .m3u, .m3u8, .m4u, .max, .mdb, .mid, .mkv, .mov, .mp3, .mp4, .mpa, .mpeg, .mpg, .msg, .pdb, .pdf, .php, .plb, .pmd, .png, .pot, .potm, .potx, .ppam, .ppj, .pps, .ppsm, .ppsx, .ppt, .pptm, .pptx, .prel, .prproj, .ps, .psd, .py, .ra, .rar, .raw, .rb, .rtf, .sdf, .sdf, .ses, .sldm, .sldx, .sql, .svg, .swf, .tif, .txt, .vcf, .vob, .wav, .wma, .wmv, .wpd, .wps, .xla, .xlam, .xll, .xlm, .xls, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .xml, .xqx, .xqx, .zip
Whoopsie ransomware uses the AES encryption algorithm in locking its files. After the files became inaccessible, it adds the .whoopsie extension to each one of the affected files. After that a pop-up window labeled “Whoopsie” will appear on the screen. This program window contains the ransom note which states:
“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?
It’s easier than it seems! Just pay a small fee of 50€ in BTC to {paymentadress} and you will get your decryption key”
How does Whoopsie ransomware spread online?
Whoopsie ransomware may spread online via malicious spam emails. This is one of the most popular methods commonly used by cyber crooks in spreading cyber threats like Whoopsie ransomware. The malicious executable file named “Tree.exe” is attached into these malicious emails and when opened, will automatically launch Whoopsie ransomware into the system.
You can eliminate Whoopsie ransomware successfully by following the given removal guide below.

Try to recover your encrypted files using the Shadow Volume copies
Restoring your encrypted files using Windows’ Previous Versions feature will only be effective if Whoopsie ransomware hasn’t deleted the shadow copies of your files. But still, this is one of the best and free methods there is, so it’s definitely worth a shot.
To restore the encrypted file, right-click on it and select Properties, a new window will pop-up, then proceed to Previous Versions. It will load the file’s previous version before it was modified. After it loads, select any of the previous versions displayed on the list like the one in the illustration below. And then click the Restore button.
