What Celas Trojan Ransomware is?


In short, it is what you just read above. In depth, my answer is: “who knows?” How would you find what the Trojan is? By the word “Celas” placed at the top or by the look of the image placed in the window asking you to pay for unknown crime? Any other Trojan or even script might easily use just the same scam and the same look, while the main purpose of the Trojan hidden under the mask might be very different and the way of removal also. Other smart Trojan might exploit Celas Trojan look, install dummy files with similar names, make the same entries in registry, and do other things just to convince you that you face and need to remove Celar Trojan. When you successfully remove this mask, Trojan is left intact and free to do what it was really designed for. Spyware program might use such a design to hide itself, and other malicious programs might do that for some reason also. Celas Trojan is just a name that became known and wide spread. Such a name might be exploited by hackers and cyber criminals.

What is known as Celas Trojan is a ransomware scam that uses social engineering and exploits people trust to messages coming from the government agency and the fear of getting in more trouble with this agency if the fine 50 EURO is not paid. Legitimacy of activities performed over the internet is not always clear, and some criminal activity might be done under user’s name by hackers. Even if all suspicious web sites and unbelievably attractive offers made over the internet are avoided by decent user, no one can be 100% sure about legitimate side. Who can say for sure that some law wasn’t violated by simple clicking made on the link? This uncertainty is used by ransomware attackers, and Celar Trojan is just a one of a kind that exploits this internet related problem.

Trojans are sneaky creatures that can pass through the wall made by antivirus software. After infiltration, they set themselves to run at the Windows startup. This design let them block starting other programs and run processes that monitor changes made by the user. Celar Trojan also monitors processes, and this makes any improper attempt of the manual removal useless. It just restores itself.
