What is PAUSA ransomware? And how does it execute its attack?

PAUSA ransomware is a file-encrypting malware created to encrypt files in a targeted PC to make them inaccessible to users. It will begin to execute its attack the moment its malicious payload is dropped into the system. According to security experts, this new ransomware threat is a variant of the STOP ransomware and SUSPENDED file extension ransomware. Just like its predecessors, PAUSA ransomware makes modifications in the Registry and create new ones to achieve persistence on the infected computer. After that, it will look for the following file types and encrypt them using both AES and RSA ciphers. Once the encryption is completed, each one of the encrypted files are marked with the “.PAUSA” extension.

.3gp, .7z, .apk, .avi, .bmp, .cdr, .cer, .chm, .conf, .css, .csv, .dat, .db, .dbf, .djvu, .dbx, .docm, ,doc, .epub, .docx .fb2, .flv, .gif, .gz, .iso .ibooks,.jpeg, .jpg, .key, .mdb .md2, .mdf, .mht, .mobi .mhtm, .mkv, .mov, .mp3, .mp4, .mpg .mpeg, .pict, .pdf, .pps, .pkg, .png, .ppt .pptx, .ppsx, .psd, .rar, .rtf, .scr, .swf, .sav, .tiff, .tif, .tbl, .torrent, .txt, .vsd, .wmv, .xls, .xlsx, .xps, .xml, .ckp, .zip, .java, .py, .asm, .c, .cpp, .cs, .js, .php, .dacpac, .rbw, .rb, .mrg, .dcx, .db3, .sql, .sqlite3, .sqlite, .sqlitedb, .psd, .psp, .pdb, .dxf, .dwg, .drw, .casb, .ccp, .cal, .cmx, .cr2

Following data encryption, PAUSA ransomware places its ransom note named “!!!RESTORE!!!.txt” on the infected computer. It contains the following message:

“All your important files were encrypted on this PC.

All files with .PAUSA extension is encrypted.

Encryption was produced using unique private key RSA-1024 generated for this computer.

According to its ransom note, victims are required to pay $600 within 3 days. If victims fail to pay the ransom in the given time, the price will increase. However, no matter how threatening the ransom note may be, paying the ransom is not the right thing to do – not only you’ll waste your money and time but you could also end up exposing your sensitive information to the crooks behind PAUSA ransomware.

How is the malicious payload of PAUSA ransomware distributed?

The malicious payload of PAUSA ransomware might be distributed using the most common way of spreading ransomware threats – spam emails. Crooks attached the malicious payload in spam emails where they pretend to be some well-known company or group and make some attention-grabbing subject to the emails to trick users into opening the email and downloading the attachment. So if you see any suspicious-looking emails in your inbox you have to delete it right away.
