The .Bukyak virus is a ransomware that is currently set against target end users on a global scale. There is no information available about the hacking group behind it. It is believed to be a new version of Aurora ransomware. This is one of the reasons why we believe that the hackers are experienced.
Once the .Bukyak virus has started it will execute its built-in sequence of dangerous commands. Depending on local conditions or the specific hacker instructions various actions will take place. The file encryption will begin after them — the encrypting component will use a built-in list of target file type extensions. In the end the victim files will be renamed with the .Bukyak extension.

.Bukyak Virus Overview
A new Aurora ransomware sample called the .Bukyak virus has been found to infect users live on the Internet. As there are a very few samples found we anticipate that the threat is still in an early testing or development phase. There are several popular infection techniques which are popular with hackers sending out ransomware. This can include phishing strategies that make use of both email messages and specially created sites. They are designed to imitate notification messages, alerts or updates that come from famous web services or companies. When the users interact with them the .Bukyak virus infection will be triggered. They ca be hosted on domain names that sound similar to the services or companies which are mentioned.
The .Bukyak virus can be spread through infection code which can be made part of various file carriers. An example would be the inclusion of malware infecting macros in documents. They can be of the popular file formats: presentations, databases, spreadsheets or plain text documents. When they are opened by the users a prompt will be shown asking for the code to be run. If this is done the ransomware will be installed. The virus can infect victims by being uploaded to file-sharing networks, commonly the hackers will use BitTorrent. This is the most popular network which is widely used to distribute pirate content.
Many of the Aurora ransomware strains which ar identified as the .Bukyak virus are spread via a phishing attack involving Microsoft. A fake Windows landing page is created which aims to fool users into thinking that they have installed a patch onto their operating system. This will present the virus after the users click on the interactive buttons.
The main engine when started will start the built-in sequence of malicious actions. It may be different depending on the local machine metrics or the overall hacking configuration as defined by the hackers. The .Bukyak virus may include a lot of modules, they can be built into the ransomware package or downloaded on demand from the Internet.
Previous Aurora ransomware and other famous malware families will most likely run typical malware actions. This includes an information gathering component. It is frequently programmed to hijack personal user details, the collected data can be use to direct various crimes. They can be identity related or financial abuse. Machine information that can be hijacked include operating system values, the installed hardware parts or the current date and time.
What’s particularly dangerous about the .Bukyak virus is that it can lead to many different types of system changes. This can include the modification of system configuration files, boot options and the Windows Registry. This can lead to a persistent infection, this means that the virus will automatically start when the computer is powered on. Modifications to the Windows Registry may cause the operating system services and user-installed applications to stop working properly. Other consequences that can be expected can be data loss or unexpected errors. Some of the Aurora ransomware samples like .Bukyak can delete data such as backups or shadow volume copies. This will make file recovery very difficult. All kinds of other extensions can be added if the hackers choose to do so. An alternative approach would be to use the .Bukyak virus as a payload carrier. This means that it can prepare the environment for much larger malware threats: Trojans or cryptocurrecy miners.
.masked Virus File (Aurora Ransomware) – How to Remove
When the first stage of the virus has completed the file encryption will follow. This will use a strong cipher to encrypt target files, usually this is done by reading the ile type extensions from a built-in list. They will be locked and renamed with the .Bukyak extension. A ransom note will be created in a file that ill be saved in folders where there are processed files. The file names can differ based on the local conditions, they can be of the following:
- (“@_FILES_WERE_ENCRYPTED_@.TXT
- @_HOW_TO_PAY_THE_RANSOM_@.TXT
- “@_HOW_TO_DECRYPT_FILES_@.TXT
The users will be blackmailed into paying a decryption fee to gain back access to their files.
