What is L1LL ransomware? And how does it implement its attack?

L1LL ransomware is a new crypto-malware discovered on March 18 this year. There is not much information about this new threat but according to security experts, it could be possible that this threat is a test release and is still under development although that does not mean that it can’t encrypt files in an infected computer.

Based on the analysis of the samples collected from this crypto-malware, once it implements its attack, it drops its payload file in the system which establishes a connection to a remote server. It collects information from the system using a data gathering module and sends them to the remote server. It then places its malicious components that are downloaded from the server and places them to different system folders. It also makes use of a stealth protection module which allows it to bypass all the security programs installed in the system to prevent them from interfering with the attack.

In addition, L1LL ransomware creates and modifies entries in the Registry which allows it to achieve persistence as well as launch or repress system processes. It then scans the computer in search for files which has the extensions listed below:

.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 finding its targeted files, L1LL ransomware starts encrypting them using a sophisticated encryption algorithm and appends the .L1LL extension to every affected file. Following data encryption, it opens a file named “help.txt” which contains the following content:

“Hello. Your files have been encrypted.

For help, write to this e-mail: jilyjily@torbox3uiot6wchz.onion
