A crypto-virus known as ECLR ransomware has reported using a strong encryption cipher to encode the files of infected computers, demanding the insane sum of 100 BitCoins for their decryption. In USD this sum equals to around 44700$ and infected users have just about two days time to pay this money if they want to see their files working again. This is the most “expensive” ransomware seen so far, and its creators do not fool around, threatening the user in the ransom note which they leave after infection. Malware researchers have not yet discovered a decryption possibility for .eclr encrypted files, but they strongly advise against paying any ransom to the cyber-crooks, for several obvious reasons. We recommend removing ECLR ransomware from your computer and attempting file restoration using methods, such as the ones presented in this article.
|Short Description||The ransomware encrypts files with a strong encryption algorithm and asks a ransom for decryption.|
|Symptoms||Files are encrypted with a .eclr file extension added to them and become inaccessible. A ransom note with instructions for paying the ransom shows as a README_IMPORTANT.txt file.|
|Distribution Method||Spam Emails, Email Attachments, File Sharing Networks, Targeted attacks.|

ECLR Ransomware – How Does It Infect
The cyber-criminals behind the ransomware may use more than one method to infect users. The primary method of infection is most likely via exploit kits. Such may deliver the malicious executable of the ransomware, reported by infected users to have the name result00.exe. So far it is a mystery on how the malicious file is dropped on the %Windows% folder, but researchers believe that a Trojan.Dropper may have been used. What is more, this ransomware is not like any other virus – it targets companies directly. This may significantly change the methods of infection since a more targeted approach may have been conducted:
Targeted attacks are very cunning and clever, and they may come when least expected. What is more, their infection rate is more successful because they are tailor made to infect the specific victim or a group of victims. They may vary:
“The lost USB Flash Drive” – this type of attack is already a cliché, but it is also very effective. The cyber-criminals may leave a flash drive somewhere on the parking lot or anywhere, containing a Trojan, worm or other malware and leaving the average user to figure out the rest. Usually, most users are curious and want to see what is in the drive, and this is what this method of infection relies on.
“The phishing e-mail” – this type of attack requires an inside person or at least access to the internal network of the organization. If the organization is small and does not have an internal infrastructure, the attack becomes significantly easier. This is because what the attacker needs to conduct a successful infection is information about the e-mail address(es) of the victim as well as other information. For example, if an attacker knows the name of the CEO of a company as well as his e-mail address, he may send a phishing mail, which looks like the CEO’s e-mail with a malicious attachment in it, saying the attachment is urgent and must be opened. This may be very effective.
“Simple spam” – this is the oldest technique of spreading the virus, via spam e-mail messages. Similar to the phishing e-mail they may contain claims that the user should click on a web link or open an attachment. However, spam messages are not as effective, because they may not be targeted, like the phishing e-mails. But they assume the same strategy, only target a wider “audience”.
“The hands-on approach” – this approach is very unlikely, but very characteristic when the attacker is within the organization. There can always be someone who can be motivated by one reason or another to be an inside person for the cyber-criminals and infect the computers of the organization with malware.
Of course, there are also other methods of infection(limited only to the cyber-criminals’ imagination) like online spam messages posted on different websites, fake installers, fake game cracks and keygens downloaded from suspicious sites and others. Infection by such randomly posted malicious files or URLs online may be the result of carelessness of the user opening them. This is also a very likely scenario.
Either way, users are strongly advised to follow several protection tips to prevent such attacks from happening in the future:
ECLR Ransomware – What Does It Do
Once it has made a computer its victim, ECLR ransomware may create the following malicious file:
The file has been detected as a WS.Malware.1 by Symantec security software and it is most likely the encryption module of the malware or the file that encrypts your data, leaving the .eclr file extension after the encrypted files, for example:
- Microsoft Excel Document.xlsx.eclr
The encrypted files are unable to be opened and their type may vary, for example:
→ “PNG .PSD .PSPIMAGE .TGA .THM .TIF .TIFF .YUV .AI .EPS .PS .SVG .INDD .PCT .PDF .XLR .XLS .XLSX .ACCDB .DB .DBF .MDB .PDB .SQL .APK .APP .BAT .CGI .COM .EXE .GADGET .JAR .PIF .WSF .DEM .GAM .NES .ROM .SAV CAD Files .DWG .DXF GIS Files .GPX .KML .KMZ .ASP .ASPX .CER .CFM .CSR .CSS .HTM .HTML .JS .JSP .PHP .RSS .XHTML. DOC .DOCX .LOG .MSG .ODT .PAGES .RTF .TEX .TXT .WPD .WPS .CSV .DAT .GED .KEY .KEYCHAIN .PPS .PPT .PPTX ..INI .PRF Encoded Files .HQX .MIM .UUE .7Z .CBR .DEB .GZ .PKG .RAR .RPM .SITX .TAR.GZ .ZIP .ZIPX .BIN .CUE .DMG .ISO .MDF .TOAST .VCD SDF .TAR .TAX2014 .TAX2015 .VCF .XML Audio Files .AIF .IFF .M3U .M4A .MID .MP3 .MPA .WAV .WMA Video Files .3G2 .3GP .ASF .AVI .FLV .M4V .MOV .MP4 .MPG .RM .SRT .SWF .VOB .WMV 3D .3DM .3DS .MAX .OBJ R.BMP .DDS .GIF .JPG ..CRX .PLUGIN .FNT .FON .OTF .TTF .CAB .CPL .CUR .DESKTHEMEPACK .DLL .DMP .DRV .ICNS .ICO .LNK .SYS .CFG”Source:fileinfo.com
Those files may be encrypted even on removable drives such as External SSD, HDD, memory cards, memory sticks and others. After the encryption process is completed, ECLR Ransomware is reported to leave two files:
- A secret.key file, which most likely contains the public key.
- A README_IMPORTANT.txt file, which contains the following text message:
→ YOUR FILES ARE FULLY ENCRYPTED

ECLR Ransomware – Conclusion, Removal and Restoration Options
As a bottom line, we have to admit that this is a ransomware that is one of a kind. For the first time we see the ransom price of 100 BitCoins which is around 44700 dollars to be requested, suggesting the ransomware means business. The cyber-criminals behind it are mainly focused on extorting organizations, which means that it may not be as widespread to the public and this may be the good news.
If you want to remove ECLR Ransomware, we suggest you follow either the manual or automatic removal instructions below. They are methodologically arranged to help you isolate and delete its malicious files. However, since this ransomware may conduct targeted attacks it may create different files for every infection and locate them in different folders. This is why malware researchers always advise using an advanced anti-malware tool focused on removing ransomware to scan for and remove the threat.
If you want to try and decrypt your files, you may want to attempt using the decryption and file restoration alternatives in step “3. Restore files encrypted by ECLR” in the manual below. In the meantime, we will continue to look for a decrypter and suggest that you follow this article or our forum for any updates. We will post one as soon as it is available.
