The latest trend used by criminals to demand ransom does not involve demanding money for a kidnapped loved one or so. These criminals are increasingly unleashing rash attacks on PCs and the data contained therein using Ransomware.
It is intensely irritating your PC becomes sluggish because a virus installed itself in your hard drive. But what about if the virus installed some embarrassing provocative content on your desktop, or your data gets encrypted so it can’t be read? Perhaps you might want to know more about Ransomware.
What is Ransomware?
Just as explained above, Ransomware is a highly sophisticated malware that encrypts files on a victim’s computer so they can’t be accessed. Currently there are two major types of Ransomware circulating on the web. An encrypting and a locker Ransomware.
The former incorporates complex encryption algorithms in computers to block files from access and demand payment of ransom so as to provide a decryption key. Examples of these include AutoLocky, CryptoWall, CryptoLocker and many others.
Locker Ransomware on the other hand locks out the victim from the operating system, which makes it very difficult to access desktop and the apps as well as files. In this case, files are not encrypted, but the attacker still demands ransom for the computer to be unlocked.
Why is a Ransomware dangerous?
There’s definitely more danger that can be caused by a Ransomware. There is nothing as dangerous in technology as a criminal who has access and control over your network. When a computer is attacked by a Ransomware, it can elevate easily from potential source of data loss to a potential identity theft. It can even go further to become a data breach in form of extortion.
So apart from just being denied access to your computer, you stand a chance of losing your identity and confidential data about your business or company going public. Nobody wants that. That’s why Decrypters are made available to overpower the Ransomware attacks and protect your computer or set free already infected files.
What are Decrypters?
Decrypters are an advanced software that has the power to decrypt the encryption algorithms used by Ransomware to set your files free. They are more of antivirus software, but rather use decryption algorithms to set free any unauthorised encryptions done on your computer and its files.
As already mentioned, there are many types of Ransomware and as such, several types of Decrypters as well to specifically deal with each type of attack. The following are the types of Decrypters for the different Ransomware.
Decrypter for Stampado
Stampado is programmed in Autolt and made available through different hacking communities. This Ransomware uses AES-256 type of encryption to encrypt files and give them a file name with a *.locked extension. The several known types of this Ransomware requests victims to make contact through firstname.lastname@example.org or email@example.com to facilitate the ransom payment.
For Decrypter for Stampado to function, you must have the attacker’s email that you are requested to make contact with as well as your ID. Bear in mind that both the email and your ID are case sensitive. Please enter each of these information in their appropriate fields in options tab.
ApocalypseVM encrypts files and gives them a name with a *.locked or *.encrypted extension. A ransom note is also included with the name *.HOW_TO_Decrypt.txt, *.How_To_Decrypt_Your_Files.txt, *.README.txt or even *.How_To_Get_Back.txt. Each encrypted file has its own ransom note included. In the ransom note, you are asked to contact firstname.lastname@example.org or email@example.com.
For this Decrypter to function, the encrypted file should have a size of 4096 bytes or more. You will also need the unencrypted version of the file. To begin the decryption process, select both the unencrypted version and the encrypted file then drag and drop them onto the Decrypter executable.
Apocalypse encrypts files and renames them with a *. Encrypted, *.Encryptedfile, *.FuckYourData or *.SecureCrypted file extension. The ransom notes are named with a *.How_to_Recover_Data.txt, *.Where_my_files.txt, *.Contact_Here_To_Recover_Your_Files.txt or *.How_To_Decrypt.txt. The ransom note requests you to contact firstname.lastname@example.org, email@example.com, firstname.lastname@example.org or email@example.com.
While in normal mode and Apocalypse displays its lock screen, you should reboot your PC into the Safe Mode via Networking. In Safe Mode, you can stop the Ransomware from running by executing MisConfig program then unchecking the Windows Update Svc. Then you can download the Apocalypse Decrypter, and save it on the desktop and run it. You can add the encrypted files using the “Add file(s)” button. Click “Decrypt” to decrypt your files.
This Decrypter is used if files on your computer have been encrypted without being renamed. The ransomware will identify itself in both ransom note and red ransomware display as BadBlock. The ransom note is named as Help decrypt.html and is located on the desktop.
Xorist ransomware encrypts files and renames them with a *.EnCiphErEd, *.p5tkjw, *.0JELvV, *.5vypSa, *.UslJ6m, *.n1wLp0 or *.YNhlv1 file extension. The ransom note can be found on the desktop, named as HOW TO DECRYPT FILES.txt.
For this Decrypter to work, the file size of the encrypted file should be 144 bytes or more. An unencrypted version of the file will also be required. To begin decryption, select each of the encrypted and unencrypted version of the file, drag and drop them onto the Decrypter executable.
This Decrypter is used when files have been encrypted and renamed with a *.777 file name extension. For the Decrypter to function properly, you may need to choose the correct malware version via the options tab.
This Decrypter is for encrypted files with a file name extension *.locky, though the base name of the file is unchanged. The ransom note is named info.html or info.txt on the desktop.
Nemucod ransomware encrypts files and gives them a *.encrypted file name extension and a ransom note with a DECRYPT.txt file name on the desktop.
For this Decrypter to work, the encrypted file must have a size of at least 510 bytes and the unencrypted version of the file must also be available. To begin decryption, select each of the encrypted and unencrypted files, drag and drop them onto the Decrypter executable.
DMALocker2 encrypts files but does not rename them. The ransomware is named DMA Locker with its ID as DMALOCK 43:41:90:35:25:13:61:92.
HydraCrypt encrypts files and gives them a *.umbrecrypt or *.hydracypt file name extension.
For the Decrypter to work, you will require both the encrypted file and its unencrypted version. That is, if your file has a .png extension, find another .png file. Select both the encrypted file and the unencrypted version, drag and drop them at a go onto Decrypter executable.
This ransomware behaves in a rather similar manner as DMALocker2; it does not rename the encrypted files. The malware is named DMA Locker with its ID as DMALOCK 41:55:16:13:51:76:67:99. This malware encrypts virtually all types of files except executable and system files. Encryption is done using the AES encryption algorithm.
To start decryption with this Decrypter, run its executable, click the “Add file(s) button to browse and select the encrypted files then click “Decrypt”. Once decryption is complete a decryption status message will be displayed.
CrypBoss encrypts files and renames them with either *.R16M01D05 or *.crypt file extension. Additionally, the ransom note found on the desktop will request you to contact firstname.lastname@example.org.
To decrypt your file, you will need an unencrypted version of your file. It should be as small as possible. Select both the encrypted and the unencrypted version on your file, drag and drop them on the Decrypter executable at the same time. The Decrypter will determine the type of encryption key based on the two files. Once a decryption key has been found, a message will be displayed. Click OK button and decryption will begin.
Gomasom encrypts files and gives them a *email@example.com_.crypt file name extension. As you can see, the file name contains the email address of the attacker for which you are expected to contact for details on how to pay the ransom. There is no ransom note created by this malware.
To decrypt, select an unencrypted version of your file and the encrypted file, drag and drop them at the same time onto the Decrypter executable. Once a decryption key has been found, it can be used to decrypt all other remaining files that have been encrypted by Gomasom.
Files are encrypted and renamed with a *.LeChiffre file name extension by the malware. The ransom not most found on the desktop will request that you contact firstname.lastname@example.org. This malware encrypts files using the Blowfish encryption algorithm.
For the Decrypter to work, it must be ran on the same system where the infection happen as decryption depends on several factors such as username, computer name and system location.
KeyBTC ransomware encrypts files and leaves a ransom note named DECRYPT_YOUR_FILES.txt. The ransom note asks the victim to reach the attacker via email@example.com to get ransom payment instructions.
The Decrypter has no way of determining whether your system was attacked by this particular malware, so you should use it only when you’re completely certain that the malware is KeyBTC. It will create a backup for all your files, but you can uncheck the backup option if you do not have sufficient space.
Radamant ransomware encrypts files and renames them to a *.rdm or a *.rrk file name extension. This Decrypter will however work for the *.rdm extension only. Even though it will work for many different types of file extensions, .txt files won’t be decrypted.
To decrypt a file, launch the Decrypter executable by double clicking and going through the steps as directed. Then on the decryption screen, click the “Add folder” button and click on “Decrypt” button. Once decryption is complete, a decryption status will be displayed on a results screen.
Files are encrypted and renamed with a *.CRINF file name extension by CryptInfinite ransomware. The malware is spread via email attachments which masquerade as job application resumes. Once infected, a victim cannot access any document. All folders that have an encrypted file will also have a ransom note with the name ReadDecryptFilesHere.txt.
The ransom note tells the victim that they only have 24 hours to send voucher code of PayPal MyCash to an email address. Some of the emails associated to this malware are firstname.lastname@example.org, email@example.com and firstname.lastname@example.org.
To begin decryption, simply select both the encrypted file and then unencrypted version of your file to the Decrypter executable at the same time. When a decryption key is found, it will be displayed on a message screen. The decryption key can then be used for all other files infected with the malware.
PClock encrypts files without changing their file name extension. The malware uses CryptoLocker as its identity name and a ransom note named enc_files.txt can be found in the directory of your user profile. There is also an upgrade of the malware called PClock2 which uses RC4 algorithm, but rather similar to its predecessor.
The decryption process is fairly simple as demonstrated with the other ransomware. Simply download the Decrypter, launch the executable and then follow the steps as directed. When the decryption screen appears, click the “add file(s)” button to add the encrypted files and click “Decrypt” button.
CryptoDefense leaves behind ransom notes called How_Decrypt.html and How_Decrypt.txt in every folder containing the encrypted file. These ransom notes contain instructions on how to make the ransom payments via a website. The malware uses the RSA-2048 encryption algorithm which eliminates the brute force decryption method.
To decrypt a file that’s been affected by this malware, run the Decrypter executable by double clicking. When the decryption screen launches, click the “Add folder” button and then click “Decrypt” button. If a decryption key is found, message that reads “Loaded private key from current user’s key storage!” will be displayed. The decryption of the files will then begin automatically.
This Decrypter is used when the ransomware encrypts your file and gives them a *.html extension and ransom note claims to be from US Department of Justice or Spamhaus.
Before decryption begins, you are required to start your computer into Safe Mode using Networking. This process is advanced and can best be done by advanced users. Ask for help if unsure.
Download the Decrypter and save it on your desktop. Double click it to launch the executable. To begin decryption once the decryption screen is displayed simply click the “Decrypt” button and the Decrypter will scan your PC for traces of files infected by Harasom. If encrypted files are detected, they will be decrypted and saved in their previous location.
