Crown Ransomware Virus

Your PC has been infected with Dharma ransomware. The name of the threat – Crown ransomware comes from the associated extension. As a typical data locker ransomware, it interferes with essential computer system settings in order to encrypt personal files and extort a ransom fee from its victims. The threat is lurking across the web in active spread campaigns. Its malicious payload file may appear in the form of a software update, software package, email attachment, advertisement, or link on social media posts.
When started on a target computer operating system, Crown ransomware initiates a complex attack that seriously damages system security. One of the main goals of the ransomware is to reach personal files so that it can encrypt them. By doing this Crown limits users’ access to their valuable data.

Crown Ransomware – Distribution and Impact
The Crown ransomware is a newly discovered cryptovirus based on the code of Dharma ransomware. Similar to its predecessors, the threat has been released in the wild with the help of shady techniques like malspam, malvertising, freeware installers, fake software update notifications, and corrupted web pages. The most preferred spread method is malspam. It is realized via massive email spam campaigns that attempt to deliver malicious code on targeted PCs.
You should look for specific traits that will help you catch a malicious spam email before it gets too late. Trait number one – attachment. Trait number two – URL address, in-text link or another clickable form that will open a tab in your browser. Trait number three – strange email address accompanied by the name of a representative of a well-known company. If any of the email elements seem unusual or suspicious, you should refrain from any interactions. A quick security check of the attached files and presented links in online services like VirusTotal can help you prevent your PC from being infected with nasty malware like Crown.
What happens when the activation file of Crown virus starts on the computer operating system is a long sequence of malicious processes. The completion of these processes enable the ransomware to evade detection, misuse main system functionalities and eventually encode valuable personal files.
As a part of Dharma ransomware family, Crown virus encrypts target files by utilizing the strong cipher algorithm AES. The encryption process is done via a built-in cipher module that scans all drives for certain types of target files.
Due to the complexity of applied changes, encrypted files remain inaccessible until their code is reverted back to its original state. Unfortunately, you may not be able to view the information stored by the following files of yours:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
Each encrypted file receives the extension .crown appended to its original name. Additionally, you could see the email address firstname.lastname@example.org as an extension. This email address is associated with cybercriminals who stand behind Crown ransomware attacks. It could be also noticed in the ransom message that appears at the end of the infection process:
