Radamant Ransomware – How Did I Get It
Similar to the 4th version of Cryptowall Ransomware, the cyber-threat may spread via spam e-mails containing either malicious web links in them that may redirect and cause a drive-by download or malicious mail attachments. The email message may resemble an official email by PayPal, eBay or some other reputable service the user may have a registration in and this increases the likeliness of someone clicking on the link/file.
Radamant Ransomware – More about It
Once downloaded and started on the user PC, the ransomware is reported to create the following registry entries:
→HKCU\Software\Microsoft\Windows\CurrentVersion\Run\svchost C:\Windows\directx.exe
HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Run\svchost C:\Windows\directx.exe
Furthermore, it is believed to create these files that are associated with the registries:
→%Desktop%\YOUR_FILES.url
C:\Windows\directx.exe
What is specific about Radamant ransomware is that it does not encrypt data immediately. Instead after the system reboots, the cyber-threat begins to scan for new files and encrypt them with the .RDM file extension and a strong AES-256 bit encryption algorithm.
So ,we advise you NOT to restart your computer before removing this nasty threat or save any new files of the following file extensions in it:
