How to remove Keq4p Ransomware and decrypt .keq4p files

What is Keq4p Ransomware

Keq4p is a ransomware infection that encrypts personal data using cryptographic algorithms. These algorithms ensure strong data protection from attempts to decrypt it. Files attacked by ransomware are usually photos, videos, music, documents, and other types of data that could entail some value. Most file-encryptors change all the affected files by assigning their own extension. Keq4p does exactly the same, but also attaches a random string of symbols. For instance, a file like 1.pdf will change to something like 1.pdfT112tM5obZYOoP4QFkev4kSFA1OPjfHsqNza12hxEMj_uCNVPRWni8s0.keq4p or similar. The assigned string is totally random and has no real purpose. Along with visual changes, Keq4p closes its encryption process with the creation of zB6F_HOW_TO_DECRYPT.txt, a text file containing ransom instructions. You can take a closer look at what it contains in the following screenshot.

At first, this ransom note notifies victims about data encryption. To decrypt blocked files and prevent them from getting disclosed on dark web resources, victims are requested to buy decryption software. This can be done after contacting extortionists via .onion link, which can be accessed only in Tor browser. In addition to that, cybercriminals advise against editing files and contacting authorities as it will make your data undecryptable. It is also said no third-party tools are capable of unlocking Keq4p files. The only way to recover your data without cybercriminals in case you are not afraid of data disclosure is to use backup copies. Backup copies that were saved and stored on external devices prior to the infection, can be used to restore data quite easily. In case no such option is available and you do not want to collaborate with cybercriminals, there are world-trusted decryptors and recovery tools that can attempt to restore your data. They are less likely to help, but still worth trying in case no other method is left. Before doing any of the recovery methods, make sure to delete Keq4p Ransomware from your computer to prevent it from running encryption again. We will help you do this below.

How Keq4p Ransomware infected your computer

Here is the list of distribution methods often abused by cybercriminals to deliver ransomware and other infections:

Malicious spam letters, trojans, backdoors, keyloggers, unreliable downloads of pirated or cracked software from unofficial and file-hosting websites like Peer-to-Peer sharing networks (Torrent clients, Gnutella, eMule, etc.), fake updates, by hacking vulnerable RDP configuration, etc.

Statistically, it is quite common to see swindlers promote their software via e-mail spam letters. They send a range of identical letters marked as “legitimate”, “urgent”, or something similar. Thanks to this minor, yet effective visual trick, many users get curious and open the received letters. In case such letters are malicious indeed, potential victims will spot either some attached files or links leading to download pages. As a rule, many malware developers use popular file formats like .DOCX, .PDF, .EXE, .RAR, .ZIP, or .JS which therefore get reconfigured for executing the installation of malware. Once one of these files is opened, victims will be unable to stop malware from penetrating a system. We recommend you to stay as far as possible from files received in such a shady way. To protect yourself against spam threats and other dangerous channels that promote malicious infections, read our guide below.
