Crypren Ransomware Description

The Crypren Ransomware is a data encryptor that attacks various file formats, including media and documents, by sending them through an encryption algorithm. The Crypren Ransomware follows this attack by depositing a message on your PC asking for money within a week before deleting your files. Besides availing yourself of free decryptors, malware analysts can suggest using backup restoration techniques, although you always should remove the Crypren Ransomware beforehand with whatever anti-malware tools are available.

The Dangers of the Even Smallest of a Trojan's Ransom

One of the ongoing, evolving aspects of the black market for threatening file encryption is the wild fluctuation in ransom values. Con artists who are extremely confident in their programming skills or are using social engineering techniques might ask for very high sums of over a thousand dollars. Others, like the Crypren Ransomware, strive for numbers of payments over quality, asking for nothing more than one-tenth of a Bitcoin (under forty USD).

The Crypren Ransomware's 2016 campaign uses still-unconfirmed distribution methods. Currently, malware researchers found no indications of the Trojan being capable of installing itself without assistance from additional threats. E-mail is the most popularly-used infection vector for threatening file encryptors, but other techniques, such as website-based exploits, sometimes are put to use.

Once proceeded past the original installation process, the Crypren Ransomware scans your PC, searching for documents (TXT, DOC), images (JPG), Web pages (HTML), music (MP3, MP4), spreadsheets (XLS), and other, 'personal content' formats. The Crypren Ransomware then sends these files through what malware researchers estimate of being an AES CBC 256-bit encryption algorithm, and adds the '.encrypted' tag to each one.

The Crypren Ransomware then loads a Web page ransom message informing the victim of the situation and asking for a comparatively small Bitcoin fee. The Crypren Ransomware also warns of a one-week time limit before the Crypren Ransomware deletes your content automatically.

No Need to Cry Over a Crypren Ransomware Payment

The Crypren Ransomware poses the same risks and shows the same shortcomings as most other Trojans with a data-encrypting payload. Although the Crypren Ransomware may delete your files once its timer expires, appropriate security strategies can remove the Crypren Ransomware before this occurs, leaving the victim with several options for data recovery. Keeping redundant backups in secure locations is, as usual, malware experts' top-recommended strategy for bypassing the need to reverse a file-encrypting attack.

Other PC security researchers have provided free decryption options for Linux machines. Research is ongoing into providing Windows ports of this tool. While still in progress, these software developments show that threats like the Crypren Ransomware rely more on bluster than technological prowess, and cannot block your data from being retrieved in perpetuity necessarily.

Disinfecting your PC and removing the Crypren Ransomware will provide your system with a sterile and safe environment for recovering your content later. Delete the Crypren Ransomware with any preferred anti-malware products, being sure to scan your PC for other threats, as well, such as Trojan downloaders that could reinstall this threat. While many file encryptors delete themselves after executing their payloads, this behavior never should be assumed of a new threat.

The Crypren Ransomware is, perhaps, humble in its ransoms for a good reason: its authors know that there are already numerous solutions to its attacks, available to any PC owner who can search the Web.
