.LR Virus File – How Did It Infect My PC and What Happened?
The .LR virus is a new release of the MedusaLocker ransomware which is a new threat designed to leverage file encrypting processes against target users data. This particular sample has been sent by an unknown hacking group by taking the original virus files and modifying them to make this new sample.
It is likely being spread by the criminals using the most common techniques. One of them is the use of phishing contents that will impersonate legitimate and authentic senders such as companies or web services. The criminals will fake images and text, they may host similar sounding domain names and even utilize self-signed certificates to appear as authentic. Alternatively, they can integrate the virus code in email messages that are prepared in a bulk-like manner.
The malicious code can be placed in file carriers that will initiate the virus delivery when run. They can be macro-infected documents which when run will present a prompt asking the users to enable the built-in scripts. This will lead to the virus installation. The other popular option is the use of infected application installers of common programs which are usually downloaded by the users from the Internet.
Common places from where you can download such files includes file-sharing networks like BitTorrent where Internet users commonly download files from, both legitimate and pirate ones.
The hackers can utilize fake or stolen credentials and post links or attachments in online communities like social networks, forums, chat rooms and etc. The files may be sent in public posts, in discussions or in private messages.
The .lr ransomware will start an extensive execution sequence once the infection has been deployed on a given host. Based on the detected samples, one of the first actions is the security bypass feature. The virus engine will scan for the presence of any installed security programs and disable them. The list includes anti-virus programs, firewalls, intrusion detection software and etc.
As this is placed in the beginning of the execution sequence it will be followed by data gathering actions. They will scan the contents of the hard drive and installed programs and hijack sensitive personal information. It can be used by the victms to carry out other crimes. The main virus engine will then continue with further dangerous system changes including the following:
- Operating System Security Bypass — Alongside the applications the malicious code will also change important operating system values and disable the Windows User Account Control. This will allow the virus to gain administrative privileges and conduct various other actions.
- Files Removal — The ransomware may remove malware data such as backups and shadow volume copies. This will make it very difficult to achieve data recovery.
- Persistent Installation — The virus will modify the boot options and run itself automatically when the computer is powered on. It may also disable access to the recovery boot options thereby making it very hard to use manual user recovery techniques.
- Trojan Horse Infections — They will initiate a local malware client that establishes a secure and persistent connection to a hacker-controlled server. This allows the criminals to overtake control of the machines and steal users files.
If any other modules are embedded they will be run in the given order by the hackers. When every one of them has finished running the actual encryption phase will start. The target data will be encrypted with a strong cipher and that will affect the files which are described in a built-in list. The strong cipher will make them inacessible and renamed with a given extension. Example data includes the following: multimedia files, archives, backups, documents and etc. All of the processed data will receive the .lr extension.
.LR Virus files infections will be accompanied by a ransom note, lockscreen, wallpaper changes or other actions that are associated with the virus deployment. The victims will be extorted to pay a decryption fee in cryptocurrency assets. As soon as an infection is detected it should be removed immediately to prevent additional damage.
