Session virus Removal Guide

What is Session ransomware?

Session ransomware is a dangerous data-locking virus that asks for Bitcoin payments

Session ransomwareSession ransomware is a type of malware that encrypts personal files and threatens to disclose sensitive information to interested parties

Session ransomware is a malicious program designed for money extortion purposes. It was first spotted in the middle of April 2022 – it belongs to a relatively broad family Makop with hundreds of variants under its belt. While cybercriminals behind it mainly target businesses and small companies, regular computer users might also be affected by it in some cases.

Once installed, the malware immediately drops thousands of malicious files on the Windows system to perform its main goal – encrypt all vulnerable files. With the help of a powerful encryption algorithm, all non-system data gets encrypted. All the affected files are appended .[ID].[].session extension and stripped of their regular icons during this process, making data inaccessible.

The ransom note +README-WARNING+.txt, which is dropped on victims' desktops, explains the situation to users and urges them to contact cybercriminals to restore all files back to normal. Of course, the decryption service is not free – crooks demand Bitcoin in return for a decryptor.

Ransom note

All cybercriminals whose main goal is to extort money from their victims make sure that their malware would drop a ransom note upon infiltration. It serves as the main communication method and provides identification IDs to each of the victims, as decryption keys are all unique, and crooks would otherwise not be able to distinguish which key belongs to which victim.

Malware delivers a ransom note in a TXT format to make sure that all victims would be able to open it via Notepad or any similar text reader. Hackers' demands are as follows:

Malware authors use a now established double-extortion technique, where they promise to disclose the company's secrets to competitors or sell them on the dark web. Most businesses use reliable backup systems, so data recovery drastically diminishes the impact of a ransomware attack.

To counter this, a new trend among criminals was established back in 2019, when malicious actors started threatening their victims by disclosing sensitive information to interested parties. This forces some of the victims to pay the ransom; this practice has also made ransomware attacks be treated as data breaches.[1]

Session ransomware virusSession ransomware stems from an established malware family known as Makop

However, there is no guarantee that cybercriminals would keep these promises, even if the ransom is paid on time. It is ultimately a decision each of the victims has to make; we do not recommend paying or even communicating with the attackers, as it would only prove that the malware scheme works. Instead, start from Session ransomware removal.

Malware removal explained

To start the remediation process, it is important to proceed with the correct steps, or the whole process might be jeopardized. Disconnecting the affected from the network and only then removing the infection, for example, is really important. Only then should you proceed with data recovery.

Disconnect from the network

Malware can be controlled by hackers if the internet connection is established – it can be sent commands via Command & Control servers, resulting in additional payload delivery or improved functions of already installed ransomware. Therefore, before you proceed with Session ransomware removal, you should disconnect all the affected Windows machines from the network as follows:

  • Type in Control Panel in Windows search and press Enter
  • Go to Network and InternetNetwork and internet
  • Click Network and Sharing CenterNetwork and internet 2
  • On the left, pick Change adapter settingsNetwork and internet 3
  • Right-click on your connection (for example, Ethernet), and select DisableNetwork and internet 4
  • Confirm with Yes.

Perform a full system scan

Once you are sure that the system is not connected to the network, you should use powerful anti-malware software and perform a full system scan with it. Security software, such as SpyHunter 5Combo Cleaner or Malwarebytes, can find and remove all the malicious components from the system at once, along with any secondary payloads that might be present on the system.

File recovery and system fix

Data encryption is a relatively complex process that ensures that victims would not be able to decipher it using simple methods. This is why each of the decryption keys is unique and uses a long string of alphanumeric characters. The longer the string, the more difficult it is to decipher, and once it reaches certain requirements, it becomes impossible to do. With the help of this scheme, crooks can sell decryption keys for large sums of money to victims.

If you choose not to pay the ransom (which we highly recommend), there are a few alternative methods that might help you restore your files. Currently, there is no working decryptor available for the newest Makop variants, which makes the data recovery rather difficult. Nonetheless, you check the suggestions below.

Attempt file recovery

Try using third-party recovery software to attempt restoring at least some of your lost files:

Make sure you make backups of locked files before you proceed, or you might corrupt them beyond repair

  • Download Data Recovery Pro.
  • Double-click the installer to launch it.
    Session ransomware
  • Follow on-screen instructions to install the software.
  • As soon as you press Finish, you can use the app.
  • Select Everything or pick individual folders where you want the files to be recovered from.Select what to recover
  • Press Next.
  • At the bottom, enable Deep scan and pick which Disks you want to be scanned.Select Deep scan
  • Press Scan and wait till it is complete.Scan
  • You can now pick which folders/files to recover – don't forget you also have the option to search by the file name!
  • Press Recover to retrieve your files.

Decryption tools might also be created for certain ransomware strains thanks to the efforts of security researchers. In some cases, law authorities seize the servers of malicious actors,[2] which allows the keys to be released by the public – reputable security vendors usually do this.

Fix damaged system files

Malware can cause tremendous damage to Windows systems to the point where a full reinstallation could be required. For example, an infection can alter the Windows registry[3] database, damage bootup, and other sections, delete or corrupt DLL files, etc. Antivirus software can't repair damaged files, and a specialized app should be used instead.

  • Download ReimageIntego
  • Click on the ReimageRepair.exe
    Reimage download
  • If User Account Control (UAC) shows up, select Yes
  • Press Install and wait till the program finishes the installation processReimage installation
  • The analysis of your machine will begin immediatelyReimage scan
  • Once complete, check the results – they will be listed in the Summary
  • You can now click on each of the issues and fix them manually

How to prevent from getting ransomware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.

 

Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
