What is Pain Locker ransomware? And how does it implement its attack?
Pain Locker ransomware is a file-encrypting malware and is the latest version of Everbe ransomware that first emerged at the end of May 2018. This new variant of Everbe uses the [[email protected]].pain extension in marking the files it encrypts. Once it infiltrates a computer, it implements a series of activities where it first launches its connection to a remote Command and Control server and sends data about the infected computer. After that, it downloads additional files which help it stay undetected from any antivirus software. Moreover, it also makes alterations in the Windows Registry in order to run on every system boot.
It then begins its process of scanning the entire drive of the computer to look for files with specific formats such as:
.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
The moment it finds these files, it encrypts them right away using a strong encryption algorithm. After encryption, Pain Locker ransomware appends the extension, [[email protected]].pain on each one of the locked files. Moreover, it also creates a text file named “!=How_recovery_files.txt” that states:
“PAIN LOCKER
Hello, dear friend!
All your files have been ENCRYPTED
Do you really want to restore your files?
Write to our email – [email protected] or [email protected] and tell us your unique ID – ID-”
If you happen to be one of the victims of this file-encrypting malware, remember that paying the ransom won’t really fix your problem as crooks can’t really be trusted. The best thing you can do is to use other alternative ways in recovering your files rather than succumbing to the crooks’ demands.
