When Cycbot malware is executed, it drops several malicious files in the Appdata folder of the victim machines, and then it tries to contact a malicious […]
In my previous article, I told the story of the very first worms and viruses. Interestingly, a groundbreaking mathemetician, John von Neumann, and a science fiction novelist, John Brunner, conceptualized them before anyone ever coded them.
We often see this sort of thing in the world of science and technology. […]
The Dirty decrypter is a crypto ransomware; its intention is to encrypt the compromised user’s pictures, documents, videos etc making them unusable. The malware coerces you to pay large sums of money to decrypt any of these files. Failure to pay this sum will cause the malware to destroy […]
