KRider Ransomware Description and Removal Instructions:
Malware Category: Ransomware
KRider Ransomware is another version of the Crypto-Ransomware viruses released in March, 2017. KRider Ransomware targets PCs running Windows OS. Every file that has been encrypted will have its extension changed to: .kr3. Unfortunately, still, there is no way of decrypting the files encrypted by KRider Ransomware.
The distribution of KRider Ransomware is related to installing different third-party toolbars, all kinds of free software, files from P2P networks and torrents, random clicking on ads, pop-up windows, banners, or even downloading attached files from your personal e-mail inbox or other file sharing applications, bogus flash player and fake video software for viewing online content.
When running, KRider Ransomware will start encrypting certain types of files stored on local or mounted network drives using a RSA-2048 bit public-key cryptography, with the private key stored only on a control server. The virus will encrypt files with the following extensions:
.3GP, .7Z, .APK, .AVI, .BMP, .CDR, .CER, .CHM, .CONF, .CSS, .CSV, .DAT, .DB, .DBF, .DJVU, .DBX, .DOCM, ,DOC, .EPUB, .DOCX .FB2, .FLV, .GIF, .GZ, .ISO .IBOOKS,.JPEG, .JPG, .KEY, .MDB .MD2, .MDF, .MHT, .MOBI .MHTM, .MKV, .MOV, .MP3, .MP4, .MPG .MPEG, .PICT, .PDF, .PPS, .PKG, .PNG, .PPT .PPTX, .PPSX, .PSD, .RAR, .RTF, .SCR, .SWF, .SAV, .TIFF, .TIF, .TBL, .TORRENT, .TXT, .VSD,.WMV, .XLS, .XLSX, .XPS, .XML, .CKP, .ZIP, .JAVA, .PY, .ASM, .C, .CPP, .CS, .JS, .PHP, .DACPAC, .RBW, .RB, .MRG, .DCX, .DB3, .SQL, .SQLITE3, .SQLITE, .SQLITEDB, .PSD, .PSP, .PDB, .DXF, .DWG, .DRW, .CASB, .CCP, .CAL, .CMX, .CR2.
KRider Ransomware will create help_your_files.html and put a shortcut to it in every folder where a file was encrypted. Those files contain instructions explaining how to pay the ransom. For the victims to pay the ransom, the virus sends them to a webpage where they can enter their personal code and access the payment page. This page can be accessed either through TOR client:
or through a normal browser:
The payment is in Bitcoins, which is untraceable.
When KRider Ransomware is initiated on the computer, it will inject deep into the system infecting Explorer.exe and svchost.exe, modify the registry to start with Windows, and disable the Automatic Repair feature. Once active, it will start the process of encrypting files. These types of ransomware are very hard to detect. Nevertheless, the virus will show its presence after the encryption finishes.
KRider Ransomware will not just encrypt files and block your computer, it will also collect valuable information that will be sent to the control servers. Such software could lead to more malware coming into your computer and even cause a loss of data. Such threats are not to be underestimated!
