What is email@example.com ransomware
Black.firstname.lastname@example.org (aleta) ransomware is a variant of crypto viruses (malware that encrypt personal files and demand a ransom). It affects all current versions of Microsoft Windows operating systems such as Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10. This ransomware virus uses long key to eliminate the possibility of brute force a key which will allow to decrypt encrypted files.
When the ransomware infection infects a machine, it uses system directories to store own files. To run automatically whenever you turn on your PC, aleta ransomware virus creates a registry entry in Windows: sections HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ Run, HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ RunOnce, HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ Run, HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ RunOnce.
Immediately after the launch, the ransomware infection scans all available drives, including network and cloud storage, to determine which files will be encrypted. The ransomware uses the file name extension, as a way to define a group of files that will be subjected to encrypting. Encrypted almost all types of files, including common as:
