Mahasaraswati Ransomware – Delivery

Mahasaraswati ransomware is delivered in a few ways. As other modern ransomware viruses, this one also uses spam emails as the main delivery method. The emails have files as attachments that have the malware code inside them. In some rare cases, the body of the email itself might activate malicious code.

Getting infected with the ransomware is also possible through social media websites or via file-sharing services. These mediums might also spread malware code disguised as an executable or a file of a useful app. The best prevention tactic against any ransomware is to avoid any and all suspicious files. Do not click, open or download files that seem fishy.

Mahasaraswati Ransomware – Information

Mahasaraswati is the name of a ransomware crypto-virus. The ransomware is presented as a program for making your computer secure as if IT professionals are offering you help. The creators of the ransomware try to push the whole thing as a service. They offer not only to unlock your files but also put a good anti-malware on your PC.

The truth is that the virus just encrypts your files and asks a ransom, although the ransom note is written in a clever way. For every day, you do not pay the money to revert the changes, the sum increases with 2 Bitcoins.

A picture and a text file with the same name are created after the encryption process is complete. Both files are named How to decrypt your files.

Both the .txt and .jpeg files contain instructions for the ransom payment and can be found in every directory with encrypted files. The .txt can be previewed in the picture below:

The ransom note cleverly written and tries to trick you that the ransomware creators are IT professionals trying to help you. Like something else has locked your files, and for them to unlock them, you need to pay 3 Bitcoins within one day. 3 Bitcoins equals to 1350 US dollars estimated from the time of this article being written. According to the instructions, the price for decryption will increase with 2 Bitcoins with each day that passes.

Do NOT pay the ransom or even think of paying. Doing this will give funds to the owner of the ransomware, which will probably be used to create a stronger virus or support other criminal activities. No way is there to know if you will get your files decrypted or if you will be contacted back in the first place.

The Mahasaraswati ransomware encrypts files of different types. It is certain that documents and pictures are going to be encrypted. Those are still one of the most precious files to users as they have valuable information on them or family photos. The encryption process of the ransomware encrypts the following file extensions:

→.html, .jpg, .jpg2, .pdf, .png, .ppt, .pptm, .pptx, .bmp, .doc, .docm, .docx, .docxml, .docz, .gif, .rtf, .tar, .targz, .targz2, .txt, .xlmv, .xls, .xlsm, .xlsx, .xml, .tarlzma, .tarxz

The list of file extensions shown above is probably incomplete, but these are the main file that will be encrypted. After the encryption process is done, all files will have the same extension – .id-[The ID of the infected user]. [email protected].

Mahasaraswati ransomware might delete Shadow Volume Copies from the Windows Operating System. You should still check this as there could be different versions of the ransomware in the wild.
