Ransomware, named VenusLocker, using AES-256 and RSA-2048 ciphers to encrypt files of infected computers has appeared in the wild, leaving the encoded objects with a .Venusf extension added to them. To purchase back their files, the users are given instructions and a deadline to pay the hefty sum of 0.15 BitCoins. The ransomware also uses a lock-screen mechanism to block the user from using the computer. Users who have become victims of this cyber-threat are advised not to pay the ransom money, remove VenusLocker from their computers and try alternative methods like the ones in this article to restore their files.

VenusLocker Ransomware – How Does It Spread
To replicate successfully and infect user PCs, the creators of VenusLocker may have undertaken a massive e-mail spam campaign. The messages of the e-mails sent to users may contain false names of people or companies that may be familiar to the user, such as the following examples of topics:
- “Your PayPal Receipt.”
- “Your account confirmation.”
- “Your bank account details.”
- “Your account has been discontinued.”
The e-mails may contain malicious attachments which are obfuscated and disguised as if they are legitimate documents. Another form of infection via those mails is to use malicious URL web links.
VenusLocker Ransomware – More Information
Once entered the computer, VenusLocker may situate its malicious files under different names in the following Windows locations:
After this, it modifies heavily the Windows Registry Editor. VenusLocker may attack and compromise the following registry keys:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization
HKEY_CURRENT_USER\Control Panel\Desktop\ScreenSaveTimeOut
HKEY_CURRENT_USER\Control Panel\
To encrypt files, VenusLocker uses an AES-256 encryption algorithm – one of the strongest in the world, which is military grade and also used by the NSA. After encryption it generates a unique AES unlock key which is also encrypted with another military grade cipher – RSA-2048 bit. VenusLocker ransomware may attack the following types of files:
After encryption, VenusLocker locks the screen and drops a ReadMe.txt file, displaying the following ransom instructions on how to contact the cyber-criminals and pay the ransom money:
