This is an article that provides specific details on JobCrypter ransomware infection as well as a step-by-step removal followed by alternative data recovery approaches.
JobCrypter is a ransomware that plagues computer systems in order to encode predefined types of files stored on them. So once it gains access to and starts its malicious files it utilizes strong cipher algorithm to modify the code of files that store valuable data. Upon encryption corrupted files could not be opened nor restored without the help of an efficient recovery solution. They could be all recognized by the distinctive extension .css that stands at the end of their original names. In addition, a ransom message written in French urges victims to pay a ransom of 1000 EURO in exchange for a decryption solution possessed by hackers.

JobCrypter Ransomware – Distribution
One of the most preferred ways for the distribution of ransomware like JobCrypter is via email spam messages. This method allows bad actors to spoof the email address and sender hoping that you will follow the instructions provided by the text message. So beware even if you see emails that are seemingly sent by the names of representatives of legitimate services like your favorite website or your internet provider, any logistics company, your bank or even any governmental institution as they may carry the ransomware payload. As of their text messages they usually attempt to provoke a sense of urgency that makes you more prone to interact with the corrupted elements immediately. Corrupted elements could be either attached files of various types (Microsoft Office files, PDFs, images, etc.) or clickable in-text links. A single interaction with any of the provided compromised elements results in the automatic download of the ransomware to your system.
For the sake of your security, before you open a dubious file on your PC you could use a free online file extractor to check the security level of the file. Tools of this kind scan the code of each uploaded file for specific malicious traits. After, the scan you could see whether the uploaded file contains malicious elements or not. The information could help you to refrain from opening corrupted files on your PC.
JobCrypter Ransomware – Overview
At first JobCrypter ransomware needs to establish and execute all malicious files that support the infection process. Files and objects associated with this threat could have names different than JobCrypter and here are some of the possible folders that may be used for their storage:
When files are executed various modifications that affect essential system settings enable the threat to evade detection and attain persistent presence. One of the ways for JobCrypter ransomware to triggers its infection files on each system start is by manipulating the functionalities of specific registry keys stored in the Windows Registry Editor. So in case of infection with this threat, the keys Run and RunOnce may store some malicious values. The reason why these keys are often targets of ransomware is their main function to execute all files and objects needed for the regular system performance.
Following encryption, which is reviewed in detail in the next paragraph, this crypto virus drops a ransom note file to inform victims about its presence and impact. The note displays a message in French that looks like the following:
Its main purpose is to blackmail you into paying hackers the demanded ransom which at this point is not clearly defined. No matter what they promise in this message it is wiser not to contact them at the provided email – email@example.com nor to pay them the ransom. Keep reading to learn what could help you to restore .css files.
Update! Recent submissions of JobCrypt samples analyzed by security experts reveal that hackers demand each victim to transfer them a ransom of € 1000 in order to recieve the specific decryption key. Additional changes are noticed in the ransom note text where the contact emails are changed to:
JobCrypter Ransomware – Encryption Process
As a primary purpose of JobCrypter ransomware could be pointed out the encryption of predefined types of files stored on the compromised host. Only after the completion of this infection stage hackers are able to blackmail victims into paying ransom for a decryption solution that is supposedly able to restore corrupted data.
For data encryption, JobCrypter utilizes a strong cipher algorithm that modifies major parts of files’ code and generates a unique key that could revert back the original code. The process aims to restrict the access to valuable information stored by corrupted files. As of the files that may be infected by JobCrypter ransomware they are likely to be all of the following:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
Upon encryption, the ransomware marks all corrupted files with the distinctive extension .css as an indicator that the access to them is blocked. Even though, hackers claim that the unique decryption key generated during the encryption stage is working and able to restore .css files their promises should not be taken for granted. There is real chance that the key they possess is broken due to bugs in their ransomware code. Furthermore, they may not contact you at all even after a successful payment of the ransom.
The good news is that there are alternative data recovery approaches that are tested to help in the restoration of corrupted files. Some of them are listed in the guide that follows. In addition, according to the security researcher Michael Gillespie, the code of the threat is crackable and he could provide help for data decryption.
