Threat Behavior of Truke Ransomware
Truke Ransomware is the recent menacing member of the giant Malware Family. It
is a variant of the devious STOP (DJVU) Ransomware & has been detected to
spread its infection at an alarming rate.
Truke Cryptovirus encrypts & locks the user & system data found on the impacted
Hard-drive & even on the network-shared location. In order to make it arduous for
the users to recover their files, Truke uses strong cryptographies such as AES &
RAS. These highly-complex Encryption Algorithms require a complicated private
key to decrypt the files.
The original files names are renamed by appending .truke extension to the
For example– The
The files targeted by the Truke Ransomware may include files with the extensions
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)
The primary purpose behind encrypting the files is to extort money by making the
victims pay Ransom for the encrypted files.
Following the encryption, Truke Virus generates a ransom note in text format
named as “_readme.txt”. A Copy of this ransom note is dropped in every existing
The Ransom Note & Amount for Truke Ransomware
Truke Ransomware delivers a ransom-demanding note on the infected system
which is in the text format & named as “_readme.txt”.
The note appears in the form of a program window & holds the title – “Attention”.
The Ransom Note for the Truke Ransomware states that the all the files are
encrypted with a complex encryption method & a private key.
To purchase the decryption key, victims are required to pay a ransom amount of
$980. In case, the victim contacts the hackers within 72 hours of encryption, they
will receive 50% discount on the ransom amount, which is $490.
In addition to that, users are asked to contact the hackers on the e-mail address –
[email protected] or [email protected]
The ransom note further prompts the users to send one encrypted file to the
Truke’s developers, which will be restored for free & sent back to the victim as a
guarantee that files can be actually decrypted.
Despite of such claims, victims are advised not to make any payment to the
hackers. Research analysis has shown that the hackers usually avoid the victims
once the ransom amount has been received.
It is evident that paying Ransom Amount yields no positive result; hence all the
encouragements to pay ransom & contact the hackers should be ignored.
Users must ensure to regular back their data, be vigilant while visiting torrent
websites & avoid clicking on the spam e-mail attachments.
