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.

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:
