Executioner (Cellat) Ransomware Distribution
The Executioner ransomware also known as Cellat ransomware is most likely spread via spam emails containing malicious email attachments, pdf attachments and Word documents prompting the user to enable Macros, etc. Most recent ransomware cases rely on this method of distribution because of its high success rates. Most users tend to be careless with suspicious emails which often lead to ransomware and malware infections. A perfect example here is the way of distribution used by the .sVn variant of the well-known Jaff ransomware.
However, there are other probable methods of infections that could be used by the creators of the Executioner crypto virus. A payload dropper which triggers its malicious script could be spread online. The ransomware may also be spreading the payload file on social media websites and file-sharing services. Another popular method of ransomware and malware distribution is via freeware packages where a program may be bundled with malicious programs.
To avoid infections of that kind, be extremely cautious when dealing with files downloaded from the Web as well as with emails sent by unknown or suspicious entities. More useful tips on avoiding ransomware are published in our forum https://sensorstechforum.com/forums/pc-tips-tricks/tips-about-ransomware/ . We advise you to read them carefully and drop a question in case you have any.
