LooCipher-Virus

LooCipher ransomware is file encryption software which restricts the access of files. The cryptography algorithm used is not yet revealed however, the algorithm used creates a unique key for every encrypted file. This key is generated on the remote server. With this decryption key, the hackers blackmail the victim with the motive to extort money. Cyber criminals demand large amount of ransom, which is equal to $330 in the form of bitcoins in exchange of the decryption key. The victim is forced to pay the ransom within 5 days after the LooCipher attack. If the victim fails to make the payment in bitcoins, the decryption key will be destroyed. As a result, you can never restore your files ever again.

Hence, the victim with the fear of losing their important data/files, get ready to pay the asked ransom. However, by paying the ransom, you support the spread of evil.

Distribution Techniques

The most preferred gateway for LooCipher virus is the spam e-mails with malicious attachments. These e-mails can appear legitimate however, the danger is buried deep in the text or the attached file. In most of the cases, these e-mails are spent with the names of well-known shipping companies. It tells us about an undelivered packet, even if you haven’t ordered anything. Sometimes they notify you about the confirmation of a shipment made by you. Either way, out of curiosity, when you open the attached file, your system is exposed to the risk of malicious LooCipher. Hence, we advise you to never open the suspicious e-mails.

In addition, another technique used by the developers to proliferate the malicious software is via software updating tool. Originally, they were designed to exploit the bugs and flaws of outdated software. However, developers are using these tools to distribute computer ransomware or viruses.

You must have heard of Trojans! It is a malicious program which makes the backdoor entry in your system. Once it is successfully installed, it will open gateways for other malicious programs.

 

Threat Behavior of LooCipher Virus

Typically, LooCipher ransomware is a malicious program that blocks the access to your files. As mentioned earlier, it gains the access of your system through the malicious file attachments in spam e-mails. Once, it infiltrates the system, it appends ‘.lcphr’ extension to the encrypted filenames. The encryption algorithm used by this malicious program is strong and generates a unique decryption key for every locked file. This key is stored on the server of LooCipher developers. After successful file encryption, you can no longer open/read your files. In order to restore your corrupted files, you are bound to purchase the decryption key by developers. Simultaneously, this devastating software creates a ransom note ‘@Please_Read_Me.txt’. Every time you try to open your virus encrypted files, the created ransom note will be displayed on your screen. The ransom note provides a link which enables you to download the decryption tool.

Ransom Note (@Please_Read_Me.txt):

Due to the powerful cryptography algorithm, the LooCipher Virus file recovery is not an easy task. It is next to impossible to restore your data without the private key. Furthermore, these cyber crooks sometimes, do not share the decryption key even after receiving the demanded ransom amount. In other words, the users are trapped in the hacker’s scam & suffered a loss of finance as well as data.

If you want to safeguard yourself from such scams, backup your data on regular basis. In addition, if you find yourself being the victim, scan you system with a good anti-virus to delete LooCipher ransomware virus. If the malicious file is found in your system, make sure to remove it immediately.
