KRider Ransomware

The KRider Ransomware is an encryption ransomware Trojan that is used to force computer users to pay large amounts of money. To accomplish this, the KRider Ransomware encrypts the victims' files, demanding the payment of a large ransom to get the decryption key, needed to recover the affected files. The KRider Ransomware represents a significant threat to computer users and their data so that appropriate precautions should be taken to minimize the damage from the KRider Ransomware attack.

The KRider Ransomware – A Ride to a Nightmare

The KRider Ransomware was first observed on March 3rd, 2017, when it was submitted to an online anti-virus platform (a common way of testing threats to see if it can pass undetected). Malware researchers believe that the KRider Ransomware does not belong to any of the major families of threats, but it is a standalone threat. The KRider Ransomware carries out a typical ransomware attack, scanning the infected computer for certain file types. The KRider Ransomware will then encrypt these files using a strong encryption algorithm. Because of the file types targeted and some details in the KRider Ransomware version analyzed by PC security analysts, it is likely that the KRider Ransomware is being used to target individual computer users. The KRider Ransomware infection is designed to encrypt the following file types:

.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.

What Happens During a KRider Ransomware Attack

Once the victim's files have been encrypted, they become inaccessible. The files encrypted by the KRider Ransomware are recognizable easily because the KRider Ransomware will add the file extension '.kr3' to the end of the files' names. The files encrypted by the KRider Ransomware will not be readable by Windows and may not be recoverable if computer users do not have the decryption key (which the con artists hold in their possession). The KRider Ransomware uses a combination of the AES-256 and RSA-2048 to encrypt victims' files. Since all communications between the KRider Ransomware and its Command and Control server are encrypted, it becomes impossible for PC security analysts to recover the data once it has become encrypted. Because of this, preventive measures are essential in limiting the extent of the attack. Once the victim's files have been compromised, the KRider Ransomware will display a ransom note demanding that the victim pays a large amount to recover the affected files. PC security researchers strongly advise computer users against paying this amount.

Recovering from a KRider Ransomware Infection

Unfortunately, once the KRider Ransomware has compromised the files, it becomes impossible to restore them. Because of this, backups are the best protection against the KRider Ransomware and similar ransomware Trojans. In fact, computer users that have backups of their files will note that this makes them completely invulnerable to attacks like the KRider Ransomware. If computer users can respond to a KRider Ransomware attack by simply deleting the KRider Ransomware with the help of a reliable security application that is fully up-to-date and then restore the affected files from backup copies on the cloud or an external memory device, then the KRider Ransomware attack becomes completely nullified. The con artists lose any leverage over the victim that allows them to demand the ransom payment. Now, more than ever, with the rise in popularity of these attacks, it has become necessary for all computer users to ensure that their data is properly backed up.
