What is Session Ransomware Virus?
Session ransomware program has appeared in active attack campaigns against users worldwide. The ransomware harasses online users by requesting hefty ransom for the decryption of valuable data. By locking files, the virus prevents victims from reviewing their content.
One of the goals of this malicious software is to damage the settings of essential system components like active security measures. In case of success, it evades detection and runs a complex attack that leaves the infected system extremely vulnerable to future malware attacks.
One of the last things Session ransomware does is the creation of a text file named +README-WARNING+.txt which stores a ransom message with more details about the ransom payment process. All files encrypted by Session ransomware receive three extensions that follow the pattern .[ID number]..session. Unfortunately, the removal of these three specific extensions cannot restore locked files. They need to be decrypted by a special key and a tool.
If you are one of Session’s virus victims then keep reading this article to learn more about its specifics and the specifics of its complete removal.
|Malicious Extension||victim’s ID number + square brackets + .session|
|Short Description||A data locker ransomware that utilizes strong cihper algorithm to encrypt personal files stored on the infected computer. It demands a ransom for a decryption solution.|
|Symptoms||Important files are locked and renamed with a long sequence of extensions which ends with the .session extension. Corrupted files remain unusable until their code is reverted back to original state.|
|Distribution Method||Spam Emails, Email Attachments, Corrupted Websites, Software Installers|

How Does Session Ransomware Spread?
The most popular method used for the distribution of malicious software by malware authors is malspam or spam emails with malicious attachments. Various commonly used types of files may be infected and set to tun malicious commands once they are opened on a computer system.
Links to hacked sites may be promoted by spam email messages too. In the cases when the malicious payload of this threat is hosted by corrupted sites, it runs on computer systems with the help of malicious scripts that perform actions in the background of all other running processes. Such links may be shared on social media and forum topics.
What Does Session Ransomware Do?
Session ransomware has been identified as a strain of a bigger ransomware family called Makop. Why is it useful to know this? Because security researchers who are investigating this ransomware could find a weakness in the code that lets them create a free decryption tool for all victims. Hopefully, this will happen soon and you will be able to restore .session files by the use of one such free tool.
Regarding the infection Session ransomware conducts, it consists of a few stages that disrupt computer security and leave the system extremely vulnerable to infections with additional malware. At first, the threat is likely to establish a bunch of malicious files on the system. These files may be added to the following major system folders:
A load of all malicious files leads to the realization of a few attack stages, each of which corrupts the computer system in a different way. The main goal of Session ransomware is to activate its built-in encryption module that is set to scan the system for target types of personal files. The module is unlikely to corrupt system files because the infected system should stay intact in order that victims can review the ransom message and follow hackers’ guidance.
Hackers try to force victims to pay a ransom fee for the decryption of their .session files. Their ransomware drops the file +README-WARNING+.txt to inform victims about its presence and impact. The following message could be read in this file:
Your data is encrypted!
Unfortunately for you, a major IT security weakness left you open to attack, your files have been encrypted

No, you should not pay ransomware extortionists. Paying them only encourages criminals and does not guarantee that the files or data will be restored. The better approach is to have a secure backup of important data and be vigilant about security in the first place.
What Happens If I Don't Pay Ransom?
If you don't pay the ransom, the hackers may still have access to your computer, data, or files and may continue to threaten to expose or delete them, or even to use them to commit cybercrimes. In some cases, they may even continue to demand additional ransom payments.
Why Is the Ransom Paid in Crypto?
Cryptocurrency is a secure and untraceable form of payment, making it the ideal choice for ransom payments. It is difficult to trace, and the transactions are almost instantaneous. This means it is nearly impossible for authorities to track the payment and recover the money.
Can Ransomware Be Detected?
Yes, ransomware can be detected. Anti-malware software and other advanced security tools can detect ransomware and alert the user when it is present on a machine. It is important to stay up-to-date on the latest security measures and to keep security software updated to ensure ransomware can be detected and prevented.
Do Ransomware Criminals Get Caught?
Yes, ransomware criminals do get caught. Law enforcement agencies, such as the FBI, have been successful in tracking down and prosecuting ransomware criminals in the US and other countries. As ransomware threats continue to increase, so does the enforcement activity.
What is a File Virus and How Do You Remove it?
A "file virus" (ransomware) is a type of malicious software that infects a computer system and encrypts its files and data, preventing the user from accessing them unless they pay a ransom.
