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

YOLO ransomware is a new crypto-virus that was discovered on the last week of January 2019 and happens to be the latest variant of the infamous Jigsaw ransomware. Its creators call themselves the “Red Team” and use the .YOLO extension to mark the affected files. According to security experts, this new Jigsaw variant still implements its attack in the same pattern as other Jigsaw variants.

The instant it drops its malicious payload named “lsass.exe” in the system, it starts to implement its attack by establishing a connection to a remote server controlled by the Red Team. This is where the other components of YOLO ransomware will be downloaded. After that, it places these components on several system folders. This allows the crypto-virus to launch or repress system processes. And as it continues its attack, it employs a data harvesting module used to obtain information from the infected machine. The data obtained is then used for the stealth protection module which allows YOLO ransomware to bypass any security programs installed in the computer. After that it alters some registry keys and sub-keys in the Windows Registry in order to automatically execute its attack on every system boot. It then scans the system for files with the following extensions:

.jpg .jpeg .raw .tif .gif .png .bmp.3dm .max.accdb .db .dbf .mdb .pdb .sql.dwg .dxf.c .cpp .cs .h .php .asp .rb .java .jar .class .py .js.aaf .aep .aepx .plb .prel .prproj .aet .ppj .psd .indd .indl .indt .indb .inx .idml .pmd .xqx .xqx .ai .eps .ps .svg .swf .fla .as3 .as.txt .doc .dot .docx .docm .dotx .dotm .docb .rtf .wpd .wps .msg .pdf .xls .xlt .xlm .xlsx .xlsm .xltx .xltm .xlsb .xla .xlam .xll .xlw .ppt .pot .pps .pptx .pptm .potx .potm .ppam .ppsx .ppsm .sldx .sldm.wav .mp3 .aif .iff .m3u .m4u .mid .mpa .wma .ra .avi .mov .mp4 .3gp .mpeg .3g2 .asf .asx .flv .mpg .wmv .vob .m3u8 .mkv.dat .csv .efx .sdf .vcf .xml .ses.rar .zip .7zip

After it finds its targeted files, YOLO ransomware will encrypt them using the AES cipher. Once it completes the encryption, it opens a program window which contains its ransom note stating:

Greeting and salutations, Blue Team.

Your personal files are deleting. Your company intellectual property is belonging to us now…

But, Red Team is not being so hearless. It will only happen if you don’t pay ransom.

However we has encrypting so as not you can access them.
