Ransomware

HARDBIT is a ransomware virus that targets Windows users to encrypt system-stored data and blackmail victims into paying a fee for decryption and non-disclosure of exfiltrated data. While rendering files inaccessible, the file-encryptor assigns some visual changes to highlight the blocked data. For instance, a file originally named 1.pdf will change to something like 1.pdf.[id-GSD557NO60].[boos@keemail.me].hardbit at the end of encryption. This newly-assigned string of symbols consists of the victim's ID, cybercriminals' e-mail address, and .hardbit extension. Immediately after the encryption process approaches its end, HARDBIT changes the desktop wallpapers and drops two files explaining decryption instructions - Help_me_for_Decrypt.hta and How To Restore Your Files.txt.

FBI Ransomware is a file encryptor that restricts access to data and blackmails victims into paying $250 for the recovery. While running encryption, the virus renames all affected files by adding the .fbi extension. For instance, a file like 1.pdf will be renamed to 1.pdf.fbi and reset its original icon as a result of this change. After this, the malicious program creates three totally empty notes (readme.txt, LOCKEDBYFBI.hta, and decryptfiles.html), which contain no information at all. The actual message is displayed in the intractable full-screen window, which opens automatically after the encryption is finished.

JiangLocker is a recent ransomware infection. Alike other malware of this type, it is designed to restrict access to potentially important pieces of data by running secure encryption. During this process, the virus assigns all blocked data with the .jiang extension. To illustrate, a file previously named 1.pdf will change to 1.pdf.jiang and reset its original icon. Following this, JiangLocker changes the desktop wallpapers, displays a pop-up window, and creates a text note called read.ini. The text note duplicates information given inside the pop-up window.

Cyberone is quite a recent ransomware infection that runs encryption of data and asks victims to pay 1 Bitcoin for its decryption. While blocking access to system-stored data, the virus assigns its own .cyberone extension, making all file icons blank. For instance, a file originally named 1.pdf will change to 1.pdf.cyberone and become no longer accessible. Note that most Cyberone versions we have observed can be decrypted for free with the help of a decryption tool released by Avast. You can find more information about it in the article below. After completing encryption, the last piece of the last to start blackmailing victims is the creation of ___RECOVER__FILES__.cyberone.txt and the display of a pop-up window containing decryption guidelines written by cybercriminals.

Diamond Ransomware is a malicious infection designed to encrypt system-stored data and blackmail victims into paying the ransom for its return. While running encryption, the virus renames all targeted files with the .diamond extension. This is simply a visual change meant to highlight the fact that users' system has been infected. Following this, ransomware developers create HOW TO RECOVER ENCRYPTED FILES.TXT - a text file containing decryption instructions.

Wizard is a ransomware virus that encrypts data with the help of AES-256 algorithms to blackmail users into paying the ransom. While restricting access to data, all affected files get renamed with the .wizard extension. For instance, a file previously titled 1.pdf will change to 1.pdf.wizard and reset its original icon. Following this, it was observed that the virus creates a text called decrypt_instructions.txt onto the desktop. This note contains information about what victims should do in order to return their encrypted files.

DataBankasi is the name of a ransomware program designed to extort money from victims off of data encryption. After the encryption occurs, all affected files get changed with the .databankasi extension becoming no longer accessible. To illustrate it with an example - a file previously named 1.pdf will change to 1.pdf.databankasi and lose its original icon as well. Following successful blockage of data, the virus creates a text file containing decryption guidelines (---BILGILENDIRME----NOTU---.txt). The text of decryption instructions is presented in the Turkish language.

TeamDarkAnon is a ransomware infection that encrypts system-stored data and extorts money from victims for its decryption. After successfully penetrating the system, TeamDarkAnon renames all encrypted files with the .anon extension. For instance, a previously working file called 1.pdf will change to 1.pdf.anon and reset its original icon. After the encryption of data is complete, the virus changes desktop wallpapers and creates a text file named HOW TO RECOVER ENCRYPTED FILES.TXT to illustrate decryption guidelines.
