What is Bubble ransomware? And how does it work?

Bubble ransomware is a file-encrypting Trojan ransomware that was first reported in the last week of June 2017. After it infiltrates your computer, it begins to scan your computer the listed file types below:

.3gp, .ac3, .accdb, .accdt, .avi, .bmp, .cdr, .csv, .DivX, .doc, .docm, .docx, .dwg, .jpeg, .jpg, .mid, .mov, .mp3, .mp4, .mpeg, .mpg, .odb, .odf, .odg, .odp, .ods, .odt, .ogg, .ogv, .otg, .otp, .ott, .pdf, .png, .rar, .tiff, .txt, .wav, .xls, .xlsm, .xlsx, .zip

It appends its file extension .bubble on the files listed above during the encryption process. After the encryption it quickly releases a ransom note as stated below:

Hello, I am Bob, do you remember the game? Unfortunately, the world has
changed and I have changed too: once spit bubbles, today i encode your file!
Well, if you want to recover your files, please contact us at
[email protected]’ and we will find a solution and will promptly send
you the unlock key to retrieve all your files… Good Lucky”

This ransom note should not frighten you for there is already a decryptor available online. So there is no need for you to worry and consider paying the ransom. All you have to do is to look for alternative ways to get rid of Bubble ransomware and recover the encrypted files without paying a cent.

The ransomware mostly preys on computers running Windows operating system. So if you have no security software installed or even if you have one but it’s weak, then you be most likely be one of the victims of this virus.

How is Bubble ransomware distributed?

Bubble ransomware is delivered to its victims through bogus invoices that appear as a PDF file with a double extension. It hides the .exe extension under the .pdf in the pdf file for example, invoice.pdf.exe. These bogus pdf files are sent out through phishing email attacks that mostly targets small and medium businesses and take advantage of the typical email traffic managed by these businesses.
