Odin ransomware removal instructions
What is Odin?
Odin is a new version of Locky ransomware. Cyber criminals proliferate Odin via malicious script files attached to spam emails. Once the script is executed, a malicious encrypted file is downloaded, decrypted, and executed using a Windows program (Rundll32.exe). This malicious file then encrypts and renames various files (for example, .doc, .ppt, .php, .html, etc.) stored on the computer. Odin has identical behavior to its previous version (Locky), however, rather than adding a ".locky" or ".zepto" extension, this version appends ".odin". The files are renamed using the "[Victim ID]-[4 symbols]-[12 symbols].odin" pattern (e.g., "sample.jpg" might be renamed to "D56F3331-E80D-9E17-8D2A-1A11D40A6BD3.odin"). Following successful encryption, Odin creates three files ("_5_HOWDO_text.html", "_HOWDO_text.bmp" [set as the desktop wallpaper], and "_HOWDO_text.html") and places them on the desktop.
Locky ransomware removal instructions
What is Locky?
Locky is ransomware distributed via malicious .doc files attached to spam email messages. Each word document contains scrambled text, which appear to be macros. When users enable macro settings in the Word program, an executable file (the ransomware) is downloaded. Various files are then encrypted. Note that Locky changes all file names to a unique 16-letter and digit combination with a .locky, .zepto or .odin file extension. Thus, it becomes virtually impossible to identify the original files. All are encrypted using the RSA-2048 and AES-1024 algorithms and, therefore, a private key (stored on remote servers controlled by cyber criminals) is required for decryption. To decrypt the files, victims must pay a ransom.
Usr0 ransomware removal instructions
What is Usr0?
Usr0 is a ransomware-type virus that infiltrates the system and encrypts a number of file types (e.g., .jpg, .doc, .ppt, etc.) stored on the infected system. This ransomware adds the ".usr0" extension to the name of each encrypted file (e.g., "sample.jpg" is renamed to "sample.jpg.usr0"). Once files are encrypted, Usr0 creates a text file ("Важная информация.txt"), placing it on the desktop.
help_dcfile ransomware removal instructions
What is help_dcfile?
Help_dcfile is a ransomware designed to encrypt files using asymmetric cryptography. During encryption, help_dcfile modifies the names of encrypted files using the "10_random_characters.xxx" pattern. For example, "sample.jpg" might be renamed to "Kf4lAyhpGm.xxx". Once the files are encrypted, help_dcfile opens a window and creates a text file ("help_dcfile.txt", placed on the desktop), both containing a ransom-demand message.
Unblockupc ransomware removal instructions
What is Unblockupc?
Unblockupc is ransomware-type malware that stealthily infiltrates the system and encrypts files using AES-128 cryptography. Unlike other ransomware, Unblockupc does not change the names of encrypted files or add any type of extension. Following successful encryption, Unblockpc generates a ransom-demand message containing a text file ("Files encrypted.txt", which is placed in each folder containing encrypted files) and changes the desktop wallpaper.
