More Information About the LockDown Ransomware Virus

LockDown virus is a dangerous ransomware designed to encrypt user’s data and extort the victims for a ransomware payment. This particular version does not appear to share code with any previously known samples, for this reason, we suspect that it is an original creation. At this time it is not known which is hacking group behind it. The low number of captured samples is indicative that not a lot of users have been infected with it.

This particular threat, like other similar viruses, can be spread using common tactics. Most of them will rely on the sending out of infected files that contain the LockDown ransomware code. Common examples are macro-infected documents across all popular file formats: presentations, text documents, databases and text documents. When they are opened by the users a prompt will ask them to enable the built-in code. If this is done the virus infection will begin automatically in the background. Another example is the creation of application installers — by taking the legitimate setup files of widely used software and adding in the code, they can be sent to the targets or uploaded to various hacker-controlled sites.

Often computer criminals will use manipulative tactics to coerce the intended targets to get infected. They can send out email messages sent in bulk that make use of templates. They will fake commonly used services and companies and link or directly attach the virus files. A similar technique is the creation of hacker-controlled sites — they are often hosted on similar-sounding domain names. Infected virus files can be distributed over file-sharing networks as well — a common example is BitTorrent. Using fake or stolen credentials the virus data may be shared on online communities: chat rooms, forums, and social networks.

The LockDown ransomware will start the integrated components and modules when the infection happens. Most of the viruses of this category include a data gathering process which is used to hijack personal files and information. The collected information can be used for blackmail purposes or to create a unique ID for every contaminated host. What usually follows is data manipulation — the LockDown virus can locate or delete backups, shadow volume copies and etc. This makes it much more difficult to restore the systems.

After these modules have finished running, many file-encrypting viruses choose to commit system changes. Most of them will edit the boot options and install the virus as a persistent threat. It will get started every time the computer is powered on. It can also block access to recovery options. The malware can edit Windows Registry values so that existing software may become non-working, performance issues can be experienced, as well as data loss.

In the end the files encryption process will be launched. It uses a strong cipher to process target files according to a built-in list of extensions. Usually the most popular files will be affected: backups, multimedia files, databases, documents and etc. All of the processed files will receive the relevant .LockDown extension.

To coerce the victims to pay a decryption fee to the criminals a text note will be created in a file called HELP_DECRYPT YOUR FILES.
