Threat Scorecard
EnigmaSoft Threat Scorecard
EnigmaSoft Threat Scorecards are assessment reports for different malware threats which have been collected and analyzed by our research team. EnigmaSoft Threat Scorecards evaluate and rank threats using several metrics including real-world and potential risk factors, trends, frequency, prevalence, and persistence. EnigmaSoft Threat Scorecards are updated regularly based on our research data and metrics and are useful for a wide range of computer users, from end users seeking solutions to remove malware from their systems to security experts analyzing threats.
EnigmaSoft Threat Scorecards display a variety of useful information, including:
Popularity Rank: The ranking of a particular threat in EnigmaSoft’s Threat Database.
Severity Level: The determined severity level of an object, represented numerically, based on our risk modeling process and research, as explained in our Threat Assessment Criteria.
Infected Computers: The number of confirmed and suspected cases of a particular threat detected on infected computers as reported by SpyHunter.

The Roblocker X Ransomware is a Trojan that is used to stunt computer users. The Roblocker X Ransomware is being distributed as a bogus updated for Roblox, a game created by the Roblox Corporation. The Roblocker X Ransomware uses a lock screen to prevent the victim from accessing the infected computer. The Roblocker X Ransomware will display a full-screen message that blocks all access. The main purpose of the Roblocker X Ransomware's lock screen is to force victims to pay a ransom needed to obtain the unlock code, which would then be used to unlock the affected computer. The Roblocker X Ransomware takes the victim's computer hostage until a ransom is paid.

How the Roblocker X Ransomware and Other Ransomware Trojans may Attack a Computer
Today, there are various ways in which ransomware Trojans may take the victims' computers hostage. The most harmful of them involves encrypting the contents of the victims' hard drives in some way, such as by putting them into a password protected archive or using a strong encryption algorithm to corrupt the victim's files. These ransomware Trojans are quite effective and nearly impossible to recover from. Fortunately, the Roblocker X Ransomware does not belong to this category. The Roblocker X Ransomware does not encrypt its victim's files, although it would like you to think that it has certainly. This is a typical tactic used by lock screen Trojans, which will merely block access to the infected computer with a lock screen and claim that they have encrypted the victim's files using a strong encryption algorithm. However, these are just empty threats meant to trick computer users into paying a large ransom under the pretense that their files have been encrypted and are not recoverable (as is the case with most real encryption ransomware Trojans).
How the Roblocker X Ransomware may Profit at the Expense of Its Victims
The Roblocker X Ransomware will try to convince the victim that the files associated with the Roblox computer game will have been encrypted by the Roblocker X Ransomware attack. To do this, the Roblocker X Ransomware will deliver the following message on its lock screen:
'OH NO, YOUR ROBLOX FILES ARE ENCRYPTED!
YEs, All ROBLOX game files has been encrypted on your system.
How to get it back?
Simply send me a message asking for the "code"
Then enter it here and i will decrypt your files. 🙂
Don't close this windows or your files are lost forever. ?
COE [TEXT BOX] Validate'
However, the Roblocker X Ransomware does not have encryption capabilities, although there is the possibility that the people responsible for the Roblocker X Ransomware attack may release a new or updated version of the Roblocker X Ransomware capable of carrying out an encryption attack and following up on its threat, a possibility that has been observed in some other lock screen Trojans.
Dealing with a Roblocker X Ransomware Infection
The Roblocker X Ransomware makes it difficult to bypass the Roblocker X Ransomware lock screen. The Roblocker X Ransomware will disable the Command Line, the Task Manager, and other features that could be used to bypass this lock screen. Fortunately, the Roblocker X Ransomware lock screen is simple to remove. Simply use the password 'PooPoo' to remove the Roblocker X Ransomware lock screen and regain access to your computer. If a new version of the Roblocker X Ransomware has infected your computer with a different unlock code, the Roblocker X Ransomware lock screen can still be bypassed through the use of an alternate start-up method, such as through the use of Safe Mode or other alternate start-up methods. A reliable security program, once access has been restored to the affected computer, can be used to remove the Roblocker X Ransomware infection itself.

Similar Families
Similar Families
This section lists other families that share similarities with this family, based on EnigmaSoft’s analysis. Many malware families are created from the same malware toolkits and use the same packing and encryption techniques but uniquely extend functionality. Similar families may also share source code, attributes, icons, subcomponents, compromised and/or invalid digital signatures, and network characteristics. Researchers leverage these similarities to rapidly and effectively triage file samples and extend malware detection rules.- Casbaneiro.A
