What is Pennywise ransomware? And how does it carry out its attack?

Pennywise ransomware is a new and modified version of Jigsaw ransomware even when its ransom note says otherwise. It has similarities with the other Jigsaw variant, also called Pennywise, which uses the .beep extension. This time, this new variant uses .pennywise extension.

Pennywise Ransomware

Like other Jigsaw variants, Pennywise ransomware still features the same behavior when it comes to its attack. It starts by dropping its malicious payload in the system which is the one that establishes a connection to a remote server. This remote server is controlled by the crooks behind Pennywise ransomware. It is where the other components of the crypto-virus are downloaded.
Following its infiltration, Pennywise ransomware will employ a data harvesting module.

This module scans the local drive for any information that could be useful for the attackers which mostly includes machine identification metrics used to create a unique ID. It also employs another module called stealth protection which scans the computer for any presence of applications like antivirus, a sandbox environment, and other security programs that might interfere with the attack.

In addition, this Jigsaw variant also messes with the Windows Registry in order to automatically execute its attack each time the infected computer is turned on. Once these modifications are completed, it scans the computer for files with the following extensions:

.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

After it finds its targeted files, Pennywise ransomware locks the infected computer with an image of Pennywise the clown, along with the following message:

“Your personal files are being deleted. Your photos, videos, documents, etc…
But, don’t worry! It will only happen if you don’t comply.
However I’ve already encrypted your personal files, so you cannot access them.
Every hour I select some of them to delete permanently, therefore I won’t be able to access them, either.
If you turn off your computer or try to close me when I start next time you will get 1000 files deleted as of punishment.
Yes, you will want me to start next time since I am the only one that is capable to decrypt your personal data for you.
And remember my dear researchers…. I’M NOT A JIGSAW VARIANT!!!!!!!!!
Meanwhile….. Do you want a balloon? Hahahahaha_”
