Bkpx ransomware removal instructions

What is Bkpx?

Bkpx is is a ransomware-type virus that belongs to the Dharma family and was discovered by Jakub Kroustek. The main purpose of Bkpx is to encrypt data stored on an infected system and keep it locked until a decryption tool is purchased and ransom is paid. The virus renames all encrypted files by adding the ".bkpx" extension plus an ID number and email address. For example, "sample.jpg" becomes "sample.jpg.id-1E857D00.[Admin@decryption.biz].bkpx", and so on. Bkpx also generates a ransom note presented in the "FILES ENCRYPTED.txt" file and opens a pop-up window.

"FILES ENCRYPTED.txt" contains email addresses (admin@decryption.biz and bigbro1@cock.li) to contact cyber criminals. According to the ransom message presented in the pop-up window, all Bkpx virus files are encrypted and, to retrieve their files, users of infected computers must contact cyber criminals via the email address provided with their assigned ID numbers. According to Bkpx developers, the ransom size depends on how quickly victims make contact. In any case, the ransom must be paid in Bitcoins. Once payment is received, victims promise to send a decryption tool that will unlock the files. Bkpx developers offer free decryption of one file as 'proof' that they are capable of restoring files and can be trusted. They also urge users not to attempt to decrypt files using methods other than their decryption tool - they state that these actions might increase the cost of decryption or cause permanent data loss. Note that cyber criminals cannot be trusted, since they usually ignore victims and do not provide decryption tools/keys, even if ransom demands are met. Unfortunately, cyber criminals often use cryptographies that generate unique keys. These are stored on remote servers accessible only by the ransomware developers. Therefore, they can use this situation to blackmail victims for release of decryption keys/tools. Furthermore, there are currently no free tools able to crack Bkpx encryption. The best way to retrieve encrypted files is to use a backup if you have previously created one.

There are many ransomware-type viruses, most of which are very similar. Typically, they encrypt files and keep them locked until decryption keys/tools are purchased from cyber criminals. In most cases the only differences between these infections are the cost of decryption and a cryptography algorithm (symmetric or asymmetric) used for encryption. Unfortunately, most of these viruses are uncrackable. File retrieval is possible only if the ransomware is in development or contains bugs, flaws. To avoid these problems in future, create regular backups and store them on remote servers or unplugged storage devices. Examples of other similar ransomware-type viruses are Dablio, FilesLocker v2. 0, and GandCrab 5.0.9

How did ransomware infect my computer? 

It is not known exactly how Bkpx developers proliferate this infection, however, most cyber criminals proliferate ransomware (and other computer infections) through spam email campaigns, trojans, unofficial software download sources, or fake software updating tools/fake updaters. Spam campaigns are used to proliferate viruses by sending emails that contain malicious attachments (Microsoft Office documents, PDF, archive, executable files, and so on). They trick people into opening attachments that download and install viruses (such as Bkpx or others). Trojans are used to cause chain infections. If installed, they proliferate other viruses by opening "backdoors". Untrustworthy software download sources (freeware download, free file hosting websites, peer-to-peer networks, etc.) present malicious/infected software as legitimate. Using these sources, cyber criminals often trick people into unintentional installation of viruses. Fake software update tools cause infections by downloading malware or other infections rather than the promised updates, or by exploiting outdated software bugs/flaws.

How to protect yourself from ransomware infections?

To keep computers safe and prevent infection by ransomware or other viruses, download, install, update software, and browse the internet carefully. Do not use third party software downloaders or installers. Download all software using official and trustworthy websites/sources. Update installed software (or operating systems) using implemented functions or tools provided by official software developers. Avoid downloading and opening attachments that are presented in emails received from unknown/suspicious addresses. If you suspect that an email is irrelevant/not concerning you, simply ignore it. Have reputable anti-spyware/anti-virus software installed and keep it enabled at all times. These programs can prevent virus attacks. If your computer is already infected with Bkpx, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.
