Clop Ransomware Description
The Clop Ransomware is an encryption ransomware Trojan that was designed to carry out encryption ransomware attacks by encrypting the victims' files to demand a ransom payment in exchange for restoring access to the compromised files. Malware researchers started noticing the Clop Ransomware on February 10, 2019, carrying out a typical ransomware campaign. It is advised that computer users take precautions against the Clop Ransomware and the many other encryption ransomware Trojans active currently.
How Computer Users can be Infected by the Clop Ransomware
The Clop Ransomware is typically delivered to the victims via corrupted spam email attachments, often in the form of Microsoft Word files with embedded macro scripts that download and install the Clop Ransomware onto the victim's computer. Once the Clop Ransomware is installed, this ransomware Trojan uses a strong encryption algorithm to make the victim's files inaccessible. The Clop Ransomware targets the user-generated files, which may include files with the following extensions:
.jpg, .jpeg, .raw, .tif, .gif, .png, .bmp, .3dm, .max, .accdb, .db, .dbf, .mdb, .pdb, .sql, .dwg, .dxf, .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, .dat, .csv, .efx, .sdf, .vcf, .xml, .ses, .qbw, .qbb, .qbm, .qbi, .qbr , .cnt, .des, .v30, .qbo, .ini, .lgb, .qwc, .qbp, .aif, .qba, .tlg, .qbx, .qby , .1pa, .qpd, .txt, .set, .iif, .nd, .rtp, .tlg, .wav, .qsm, .qss, .qst, .fx0, .fx1, .mx0, .fpx, .fxr, .fim, .ptb, .ai, .pfb, .cgn, .vsd, .cdr, .cmx, .cpt, .csl, .cur, .des, .dsf, .ds4, , .drw, .eps, .ps, .prn, .gif, .pcd, .pct, .pcx, .plt, .rif, .svg, .swf, .tga, .tiff, .psp, .ttf, .wpd, .wpg, .wi, .raw, .wmf, .txt, .cal, .cpx, .shw, .clk, .cdx, .cdt, .fpx, .fmv, .img, .gem, .xcf, .pic, .mac, .met, .pp4, .pp5, .ppf, .nap, .pat, .ps, .prn, .sct, .vsd, .wk3, .wk4, .xpm, .zip, .rar.
The Clop Ransomware attack makes the encrypted files very easy to be spotted because they will be marked with the file extension '.Clop' added to the end of each affected file's name. The Clop Ransomware will then deliver a ransom note to the victim's machine. This ransom demand takes the form of a text note named 'ClopReadMe.txt,' which contains the following text message for the victim of the attack:
'Your network has been penetrated.
All files on each host in the network have been encrypted with a strong algorithm.
Backups were either encrypted or deleted or backup disks were formatted.
Shadow copies also removed, so F8 or any other methods may damage encrypted data but not recover.
We exclusively have decryption software for your situation
No decryption software is available in the public.
DO NOT RESET OR SHUTDOWN – files may be damaged.
DO NOT RENAME OR MOVE the encrypted and readme files.
DO NOT DELETE readme files.
This may lead to the impossibility of recovery of the certain files.
Photorec, RannohDecryptor etc. repair tools are useless and can destroy your files irreversibly.
If you want to restore your files write to emails (contacts are at the bottom of the sheet) and attach 2-3 encrypted files
(Less than 5 Mb each, non-archived and your files should not contain valuable information
(Databases, backups, large excel sheets, etc.)).
You will receive decrypted samples and our conditions how to get the decoder.
Your warranty - decrypted samples.
Do not rename encrypted files.
Do not try to decrypt your data using third party software.
We don`t need your files and your information.
But after 2 weeks all your files and keys will be deleted automatically.
The final price depends on how fast you write to us.
Dealing with the Clop Ransomware
It is a good decision if the computer users choose to ignore the contents of the Clop Ransomware ransom note. The best way to protect your data from the Clop Ransomware is to have backup copies of your files. However, if the computer user has an updated and effective security program, the Clop Ransomware can be prevented.
