How CRYPTER v2.40 ransomware behaves

From our report of May 2022 · not reviewed since

CRYPTER v2.40 ransomware can permanently damage users' personal files including photos, and documents

CRYPTER v2.40 ransomware is a dangerous program that can cause irreparable damage to victims, their files, and the machine.

When it infiltrates the system, it starts using complicated encryption algorithms to lock users' personal files. This includes photos, videos, documents, etc.

When the encryption process is done, the affected files are appended with the .crypter extension. For example, if a file was previously named picture.jpg, now it would look like this - picture.jpg.crypter. The icons also turn to white pages so thumbnails are no more available.

Users may also notice that they cannot open their files or use them in any way. That is where the ransom note comes in. A pop-up window appears on the screen informing users about what has happened to their files and what needs to be done to get them back. Cybercriminals ask to be paid in return for a decryption key.

The ransom note

The full pop-up ransom note from CRYPTER v2.40 ransomware creators reads as follows:

The threat actors explain to victims that their files have been encrypted because they were probably not careful enough on the Internet. They also ask for 0.08134 BTC (which is about $2580 at the time of writing) in return for a decryption key. Cybercriminals use scare tactics to make victims act as quickly as possible without thinking clearly.

Cryptocurrencies are chosen as a form of payment because they are anonymous. It is also impossible to get a refund. Once you send a cryptocurrency transaction to someone, it is irreversible. We strongly advise against paying the ransomware developers because they cannot be trusted.

Many previous ransomware victims have come forward and reported that they never heard back from them after they sent the money. Even though there is almost no other way to get your files back, you might also get scammed if you take the risk. In this guide, you will find a third-party recovery solution that can help in some cases.

Distribution methods

Although it is unknown how specifically CRYPTER v2.40 ransomware is spread, there are some general tactics that cybercriminals use.

Most often, people get infected with ransomware when installing "cracked" software from torrent sites, and peer-to-peer file-sharing platforms. These websites are unregulated, so they are the perfect breeding ground for all kinds of malware.

It is best to use only official web stores and developer sites whenever you want to install software. Apps that get listed on digital marketplaces have to go through an extensive review process. You should also always do your research - read the reviews, look at the ratings, and the number of users.

Another possibility is that the malicious file appeared in your system through email. Crooks can disguise the emails using social engineering methods and include infected attachments. That is why it is best not to open any email attachments that you are not sure of. Even if the attachment came from someone you know, it is best to double-check with them through another platform.

You might also not realize how important it is to keep your operating system and software updated. Hackers can use software vulnerabilities to deliver their malicious programs. Software developers regularly release security patches which should be installed as soon as possible if you want to keep your system safe.

Text of the ransom note

CRYPTER v2.40

CRYPTER

YOUR FILES HAVE BEEN ENCRYPTED!

Ooooop!! If you are seeing this message, it means you weren't careful about what you clicked on! Tisk, Tisk!!

If you are sure that you have been careful - well, thats even worse - that means someone else wasn't, and that this virus has now started to spread from computer to computer on your local network!!

I hope you see this and mitigate the spread before its too late.....

Well, anyway....

Each computer affected has a different key, meaning you'll need to pay for them all seperatly.

Thanks now, Have a nice day.

How to remove CRYPTER v2.40 ransomware

Tools you'll need

All of these are free except where noted. Download them on a clean device if the infected PC is offline.

  • A USB stick: to keep the ransom note, two or three encrypted files and screenshots off the infected PC.
  • Microsoft Defender Offline: built into Windows 11 and Windows 10; scans before Windows starts, so running malware cannot hide.
  • Microsoft Safety Scanner: a second, portable scanner with current signatures; each download works for 10 days.
  • ID Ransomware: identifies the family from the note and one encrypted file and says whether a decryptor exists.
  • No More Ransom: the free decryptors from police and security companies; check it again every few months.
  • Fortect (optional): scans Windows for malware and repairs the system files and settings it damaged. The free scan is in the box above.

How to remove CRYPTER v2.40 and get your files back

Work in this order.

Disconnecting comes first, removal comes before any restore, and nothing here asks you to contact the attackers.

  1. Step 1: Disconnect the PC and unplug backup drives

    CRYPTER v2.40 encrypts everything it can reach, including drives and shares you connect later. Cut the network first: cable out, or Wi-Fi off from the taskbar.

    Then unplug every USB stick and backup disk and pause cloud sync, so the encrypted versions do not replace your online copies. Do not reconnect any of them until the ransomware is removed from the Windows 11 or Windows 10 PC.

    Windows 11: turn off Wi-Fi to take the PC offline.

  2. Step 2: Save the ransom note and confirm the family

    Copy the ransom note and one or two files ending in .crypter to a USB stick, and leave the originals where they are.

    From another device, upload the note and a sample file to ID Ransomware or No More Ransom's Crypto Sheriff, which name the family from the note, the extension and the file structure.

    Write down the contact address and your personal ID from the note, because a decryptor or the police may ask for them.

    Warning: Never contact the attackers from the infected Windows 11 or Windows 10 PC.

  3. Step 3: Check for a free decryptor

    For CRYPTER v2.40, no free decryptor is known (checked 7 October 2026). Search the family name in the No More Ransom decryption tools list and in the free decryptors of Emsisoft, Avast and Kaspersky, because new tools appear years after an attack.

    Important: Keep the encrypted files even if nothing works today, and do not pay before every free option is ruled out: payment does not guarantee a working key.

    Decryptors run on Windows 11 and Windows 10, but only after the ransomware itself is removed.

  4. Step 4: Remove the ransomware before you restore or decrypt

    Restoring or decrypting files while CRYPTER v2.40 still runs lets it encrypt them again. Run a Full scan in Windows Security > Virus & threat protection > Scan options, then the Microsoft Defender Antivirus (offline scan).

    If the ransomware blocks Windows Security, start Safe Mode with Networking and scan from there. Some families install a password stealer as well, so let both scans finish on Windows 11 or Windows 10.

    Windows 11: Windows Security > Virus & threat protection > Scan options.

    Full procedure with screenshots: Run a Microsoft Defender Offline scan

  5. Step 5: Look for shadow copies of the files

    Open Command Prompt as administrator and run vssadmin list shadows. If it lists copies dated before the attack, right-click a folder with encrypted files in File Explorer, choose Properties > Previous Versions, and open or restore a version from before that date.

    ShadowExplorer, a free tool, shows the same copies when the tab is empty or hidden. Most current families delete shadow copies, so an empty list is normal, but the check takes two minutes on Windows 11 or Windows 10.

    Command Prompt running vssadmin list shadows
    Windows 11: vssadmin list shadows shows whether shadow copies exist.

  6. Step 6: Restore the files from a backup or recover deleted originals

    Restore from an external backup, File History or OneDrive's version history, choosing a date before the attack. Connect the backup drive only after the scans are clean, or the ransomware encrypts it too.

    If there is no backup, file recovery software can sometimes find the deleted originals, because some ransomware writes an encrypted copy and deletes the original file.

    Stop writing to the drive and try recovery on Windows 11 or Windows 10 before new files overwrite the space.

Find a working decryptor for your files

File encryption is a process that is similar to applying a password to a particular file or folder. However, from a technical point of view, encryption is fundamentally different due to its complexity. By using encryption, threat actors use a unique set of alphanumeric characters as a password that can not easily be deciphered if the process is performed correctly.

There are several algorithms that can be used to lock data (whether for good or bad reasons); for example, AES uses the symmetric method of encryption, meaning that the key used to lock and unlock files is the same. Unfortunately, it is only accessible to the attackers who hold it on a remote server - they ask for a payment in exchange for it. This simple principle is what allows ransomware authors to prosper in this illegal business.

While many high-profile ransomware strains such as Djvu or Dharma use immaculate encryption methods, there are plenty of failures that can be observed within the code of some novice malware developers. For example, the keys could be stored locally, which would allow users to regain access to their files without paying. In some cases, ransomware does not even encrypt files due to bugs, although victims might believe the opposite due to the ransom note that shows up right after the infection and data encryption is completed.

Therefore, regardless of which crypto-malware affects your files, you should try to find the relevant decryptor if such exists. Security researchers are in a constant battle against cybercriminals. In some cases, they manage to create a working decryption tool that would allow victims to recover files for free.

Once you have identified which ransomware you are affected by, you should check the following links for a decryptor:

  • No More Ransom Project
  • Free Ransomware Decryptors by Kaspersky
  • Free Ransomware Decryption Tools from Emsisoft
  • Avast decryptors

No More Ransom Project

If you can't find a decryptor that works for you, you should try the alternative methods we list below. Additionally, it is worth mentioning that it sometimes takes years for a working decryption tool to be developed, so there are always hopes for the future.

Create data backups to avoid file loss in the future
Report the incident to your local authorities

Ransomware is a lucrative, highly illegal business, and authorities are actively targeting ransomware operators. The level of investigation and follow-up depends on the country, the scale of the incident, and whether the attack is linked to known ransomware groups. To increase the likelihood of identifying the culprits, the agencies need information. In many cases, reports are used primarily for intelligence gathering, trend analysis, and victim support rather than immediate identification of attackers.

Therefore, by reporting the crime, you could help stop the cybercriminal activities and catch the threat actors. Reporting does not guarantee investigation or recovery of data, but it contributes to broader efforts to track ransomware campaigns. Make sure you include all the possible details, including how did you notice the attack, when it happened, etc. Relevant details may also include affected systems, ransom demands, cryptocurrency wallet addresses, and any communication with the attackers. Additionally, providing documents such as ransom notes, encrypted files, or malware executables would be beneficial.

Law enforcement agencies typically deal with online fraud and cybercrime, although it depends on where you live. Here is the list of local authority groups that handle incidents like ransomware attacks, sorted by country:

  • USA - Internet Crime Complaint Center IC3
  • United Kingdom - ActionFraud
  • Canada - Canadian Anti-Fraud Centre
  • Australia - ScamWatch
  • New Zealand - ConsumerProtection
  • Germany - Polizei
  • France - Ministère de l'Intérieur

Internet Crime Complaint Center IC3

If your country is not listed above, you should contact the local police department or communications center.

Isolate the infected computer

Some ransomware strains aim to infect not only one computer but hijack the entire network. As soon as one of the machines is infected, malware can spread via the network and encrypt files everywhere else, including Network Attached Storage (NAS) devices. NAS devices are commonly compromised via reused administrator credentials and remote access services, and attackers may also delete existing snapshots. If your computer is connected to a network, it is important to isolate it to prevent re-infection after ransomware removal is complete.

In modern environments, ransomware often spreads using stolen credentials, remote management tools, VPN connections, and cloud synchronization services, not only through shared network drives.

The easiest way to disconnect a PC from everything is simply to plug out the ethernet cable. This does not disconnect wireless networks, VPN connections, or cloud services, which must also be disabled separately. However, in the corporate environment, this might be extremely difficult to do (also would take a long time). In many organizations, devices are centrally managed, and network isolation is typically performed by IT or security teams using endpoint security or device management tools. The method below will disconnect from all the networks, including local and the internet, isolating each of the machines involved.

On modern Windows systems, network connections can also be disabled through the Settings app or automatically isolated using endpoint detection and response (EDR) tools.

  • 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.

If you are using some type of cloud storage you are connected to, you should disconnect from it immediately. It is also advisable to disconnect all the external devices, such as USB flash sticks, external HDDs, etc. Once the malware elimination process is finished, you can connect your computers to the network and internet, as explained above, but by pressing Enable instead. Before reconnecting, credentials should be reset, persistence mechanisms checked, and backups verified to ensure reinfection does not occur.

Remove the intruder from your machine

The first thing you have to do is remove the malicious files that are executing the tasks.

If you try to recover the files without eliminating the cause, it can encrypt your files again and result in more damage. Removing the virus yourself should not be an option unless you have experience in this and know what you are doing.

This security software should find all the related files and entries and remove them automatically for you. Automatic removal is the best option because there is less risk of leaving some of the files on our system.

Another thing to note is the malicious program could be preventing you from using the antivirus software, so check that first. If you are unable to do it, proceed with accessing Safe Mode on Windows:

Windows 7 / Vista / XP

Windows 10 / Windows 8

  • Click Start > Shutdown > Restart > OK.
  • When your computer becomes active, start pressing F8 button (if that does not work, try F2, F12, Del, etc. - it all depends on your motherboard model) multiple times until you see the Advanced Boot Options window.
  • Select Safe Mode with Networking from the list.
  • Right-click on Start button and select Settings.
  • On the left side of the window, pick Recovery.
  • Click Restart now.
  • Select Troubleshoot.
  • Go to Advanced options.
  • Select Startup Settings.
  • Click Restart.
  • Press 5 or click 5) Enable Safe Mode with Networking.

Data recovery options

Only hackers hold the decryption key, which can unlock your files, so if you did not back them up previously, you possibly lost your files forever.

You can try using data recovery software, but third-party programs cannot always decrypt the files. We suggest at least trying it because it cannot hurt.

Important - only do this if you have already removed CRYPTER v2.40 ransomware

Before proceeding, you must copy the corrupted files and place them in a USB flash drive or another external storage. In case something happens, you will at least still have the encrypted files.

  • Download .
  • Double-click the installer to launch it.
  • 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.
  • Press Next.
  • At the bottom, enable Deep scan and pick which Disks you want to be scanned.
  • Press Scan and wait till it is complete.
  • 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.

Report it and recover your files

Report it

Report the attack even if you do not expect the files back: insurers and banks ask for the report number, and police use the contacts in the note to link cases.

United States
FBI IC3 · FTC ReportFraud

Give the victim ID, the note and the date the files were encrypted. A business that holds personal data may also have to notify its data protection authority, in the EU within 72 hours.

Protect the files you restore

Restore only after the scans are clean and the PC no longer shows files that end in .crypter and no longer open; otherwise the restored copies can be damaged again.

Then build a backup that survives the next infection:

  • one copy in the cloud with version history
  • one on an external drive that is disconnected between backups
  • the working copy on the PC

Version history matters because a backup that syncs damaged files overwrites the good ones.

How to do this with the tools built into Windows: the 3-2-1 backup rule on Windows.

Protect your privacy - employ a VPN

There are several ways how to make your online time more private - you can access an incognito tab.

However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise.

Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and VPN will let you browse the Internet without a feeling of being spied or targeted by criminals.

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers - human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence.

In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. is one of the leading file recovery solutions you can find on the market - it is likely to restore even lost emails or data located on an external device.

Questions about CRYPTER v2.40 ransomware

Is there a decryptor for .crypter files?

That depends on the family behind the .crypter extension, which this guide cannot confirm yet from the reports alone. Check No More Ransom and ID Ransomware with your ransom note and one encrypted file; they list families with free tools.

If none exists today, keep the encrypted files and a copy of the note on a separate drive, because decryptors are sometimes published months later after flaws are found or servers are seized. Never buy a decryptor from a website that is not the security company that made it.

Should I pay the ransom in the ransom note?

Not before you have tried everything else. Identify the family from the ransom note and one encrypted file, check No More Ransom for a free decryptor, and look for clean copies in OneDrive, backups and Previous Versions.

Paying funds further attacks, may be illegal if the group is sanctioned, and is no promise of a working key: many victims get partial or broken decryption. If you consider paying for business-critical data, involve the police and a professional incident responder first, and never pay through intermediaries who promise their own decryption.

How do I open .crypter files?

You cannot open them by renaming or by choosing another program. The .crypter ending shows that CRYPTER v2.40 encrypted the content, and only the matching key can reverse it. Renaming a file back to .docx or .jpg changes nothing except the icon, and it can confuse a future decryptor, so leave the names as they are.

To get the content back, use a backup, an unencrypted copy elsewhere, or a decryptor listed on No More Ransom if one exists for CRYPTER v2.40. Store the encrypted files on an external disk until then.

Can a data-recovery company decrypt my files for a fee?

Only if a decryptor already exists or the company pays the attackers for you. Some "ransomware recovery" services advertise that they can decrypt families with no known flaw; in practice they negotiate with the attackers and add their own fee. Others use the same free tools listed on No More Ransom.

Before you hire anyone, ask in writing how they will recover the files, whether they will contact the attackers and what happens if they fail. A legitimate service answers clearly. If a free decryptor exists for your family, you can run it yourself.

How did CRYPTER v2.40 get on my computer?

The way CRYPTER v2.40 spreads has not been documented yet, so look at your own recent activity. On home PCs, ransomware most often comes with cracked programs, game cheats, key generators and fake updates, or with an e-mail attachment that was opened. On business networks, attackers usually log in through Remote Desktop with a stolen or guessed password.

Think back to what was downloaded or installed in the days before files that end in .crypter and no longer open, and check the Downloads folder and Installed apps sorted by date. Keep anything suspicious for your report, but do not run it again.

Did CRYPTER v2.40 steal my files or passwords?

We do not know yet. Nothing published so far shows data theft by CRYPTER v2.40, but the only confirmed sign is files that end in .crypter and no longer open, which says nothing about what happened before. Many current ransomware attacks copy files or run a password stealer first, so it is wise to act as if they did.

From a clean device, change the passwords that were saved in the browsers on this PC, starting with e-mail and banking, sign out of all sessions and turn on two-step verification. Watch bank statements and account activity for the next few weeks.

Is CRYPTER v2.40 the same as other ransomware with a similar name?

Not necessarily. Ransomware names come from the file extension, the note or a word in the code, so unrelated families often end up with similar names, and one family can appear under several names. The difference matters: a decryptor or advice for one family does not fit another and can damage files.

Compare the ending added to your files and the exact name of the note with the summary table at the top of this guide, then upload the note and one encrypted file to ID Ransomware from a clean device. If the result names another family, follow the guide for that family instead.

Can I delete the ransom note?

Yes, the note itself is harmless text and deleting it does not affect your files. Keep at least one copy first, outside the infected PC. the ransom note contains your personal ID and the attackers' contact details, which identification services use to tell which family encrypted your files, and which a decryptor may need later.

Police reports also ask for it. Once you have saved a copy, you can remove the notes from every folder after the ransomware program has been removed and your files are restored or backed up.

Will .crypter spread to my other drives?

It can. Ransomware encrypts every drive and network share it can reach while it runs, so external disks, USB sticks and shared folders connected during the attack may also have files ending in .crypter. Disconnect everything now, then check each device from a clean computer.

Do not plug a backup drive into the infected PC until the ransomware has been removed with an offline scan. Cloud folders such as OneDrive sync the encrypted versions, but they keep earlier versions you can usually restore.

Will Fortect remove CRYPTER v2.40?

Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.

For CRYPTER v2.40, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.

Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
