The LOPTR ransomware virus is the the latest iteration of the Locky malware family that has just been identified in an ongoing attack. The virus encrypts user data and adds the .loptr file extension to the affected files. The hackers extort the victims to pay a fee to restore their files. Victims can remove LOPTR virus in 2 ways:

Loptr Ransomware Virus Description
The LOPTR ransomware virus has been identified by malware researchers. As it stems from an advanced malware family it may cause other issues, including performance problems and dangerous system modifications. The LOPTR ransomware virus follows the behavior patterns of the last major version of Locky – the .Aesir Locky ransomware virus.
The aim of the LOPTR ransomware virus is to modify the system thereby achieving a persistent state of execution. This means that the malicious core engine is able to monitor the victims actions and guard itself against manual removal. Most of the viruses associated with this family are customized copies of the same core. This means that the LOPTR is also able to cause additional damage to the victim computers upon infection.
A popular tactic is the inclusion of stealth protection features. This means that the LOPTR virus is able to check if the infected host is running in a virtual machine, sandbox environment or a debugging testing machine.Every infected machine is assigned a unique victim during the initial infection. It uses harvested system information to calculate the value.
It may also search for any installed or running security software that are disabled and potentially removed. Depending on the configuration of the individual malware samples the engine might perform additional checks and actions. After the initial vectors are complete the LOPTR ransomware virus begins to encrypt a predefined list of files. The encryption module uses a built-in list of target file type extensions that are marked with the .loptr file extension. Previous versions of the Locky malware family have targeted a large list of file type extensions that are due to be processed:

As usual the victims are extorted to pay a ransomware fee in the Bitcoins digital currency. The exact sum is displayed in the crafted payment gateway that is hosted on the anonymous TOR network. The hidden service may present a varying fee depending on the size and nature of the affected user data.
The computer users are instructed to visit the LOPTR ransomware virus site where other tricks may be imposed – a time limit, trial decryption options and etc.
Loptr Ransomware Virus Distribution
The LOPTR ransomware virus is usually delivered via email spam campaigns or exploit kits. Examples include the Rig Exploit Kit and hacker intrusion attempts such as OPM breach.
Other LOPTR ransomware virus spreda tactics include direct intrusion attempts using automated software vulnerability testing frameworks. Computer users can protect themselves from any incoming attacks by using a quality anti-spyware solution as well as ensuring that they have updated all installed software to the latest available versions.
The LOPTR virus can also be found in modified software installers. Hackers take legitimate software packages and bundle the malicious code on them. The executables are then posted on various download sites and portals that pose as official sources. In a similar manner the criminals create infected Office documents that download the LOPTR ransomware virus when the victims interact with the built-in scripts (macros).
According to the research performed by the security specialists often P2P networks like BitTorrent also serve a large part of the virus samples.
