Files are encrypted with .vasud extension &

Threat Behavior of Vusad Ransomware The attack of Vusad Ransomware begins with encrypting user & system files on
the infected system. These files may include audio files, video files, image files &
documents containing sensitive information of the user.
The files are encrypted with high-complex cryptographies such as RAS (Rivest–
Shamir–Adleman) & AES (Advanced Encryption Standard). These encryption
algorithms are used to generate a unique private key for every infected system. The
private keys are stored on the hacker’s server.
Files once encrypted are appended with a malicious .Vusad extension. This
extension makes the files unreadable & inaccessible to the victim.
A file named “presentation.ppt” might be renamed as “presentation.ppt.vusad”
after encryption.
Certain file extensions that .Vusad file virus is capable of encrypting are mentioned
below▪ Document files (.docx, .doc, .odt, .rtf, .text, .pdf, .htm, .ppt)
▪ Audio Files (.mp3, .aif, .iff, .m3u, .m4u, .mid, .mpa, .wma, .ra, .avi,
.mov, .mp4)
▪ Video Files (.3gp, .mpeg, .3g2, .asf, .asx, .flv, .mpg, .wmv, .vob)
▪ Images (.jpg, .jpeg, .raw, .tif, .gif, .png)
▪ Backup Files (.bck, .bckp, .tmp, .gho)
Details of the Ransom Note & Amount for Vusad Crypto Virus
After the successful encryption of the targeted files, Vusad Ransomware drops a
ransom-demanding note in every folder that contains .Vusad files. This note is in a
text format & named “_readme.txt”.
The ransom-note appears every time a victim tries to access the encrypted files.
It explains the victims about the current situation of the system & instructions for
the victims to get their data restored.
It states that paying ransom is the only way to restore the encrypted data. The
decryption requires Vusad decryption tool & a private key, which is stored on the
hacker’s server.
In order to obtain that, victims are required to pay a hefty ransom amount of $980
in Bitcoins to the hackers. The victims may write to the hackers on their e-mail [email protected] & [email protected]
The ransom-message further promises 50% discount on the ransom amount (i.e.,
$480 in bitcoins) to every victim that contacts hackers within 72 hours of the
Vusad Encryption.
Fake Claims of Decryption by the Hackers
In order to take the victims into thinking that decryption is possible, the hackers
offer to decrypt one .Vusad file free of cost. The victims are required to send any
one file to the hackers on their e-mail id. The file sent for decryption must not
contain any sensitive/important information.
After decryption, the file will be sent back to the victim as a guarantee of
decryption.
Impacted users often tend to contact the hackers as they fear losing the data.
However, contacting the hackers & paying the ransom doesn’t always yield
positive results.
The analysis shows that victims often stop receiving response from the hackers
after the payment has been made.
Therefore, the impacted users must act smart & do not let hackers extort their hardearned money.
