What is Ransomware?

In this typical cyberattack, basically hackers send their victims an email that includes a link to what appears to be for an innocuous web address or email attachment. And in this case hackers appear to have sent their victims encrypted. Zip file attachments intended to make it more difficult to detect their nefarious purpose. And when victims who click on that attachment soon find their computers infected.

Who is behind the attack

And senior director at Crypsis Group Mr. Jason Rebholz, said that victims cold try to search the web for a decryption service, but chances are that in a sophisticated attack like this one, cybercriminals had already taken steps to immunize their encryption from such services.

If anyone was harmed
