The concept of file encrypting ransomware was invented and implemented by Young and Yung at Columbia University and was presented at the 1996 IEEE Security & Privacy conference.It is called cryptoviral extortion and it was inspired by the fictional facehugger in the movie Alien.
While some simple ransomware may lock the system in a way which is not difficult for a knowledgeable person to reverse, more advanced malware uses a technique called cryptoviral extortion, in which it encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them.
The Crypto Locker technique was widely copied in the months following, including Crypto Locker 2.0 (though not to be related to Crypto Locker), Crypto Defense (which initially contained a major design flaw that stored the private key on the infected system in a user-retrievable location, due to its use of Windows' built-in encryption APIs), These LNK shortcut files install Locky ransomware by automating infection operations rather than relying on traditional user downloads of WSF files—all of which is made possible by the universal Power Shell Windows application.
Unfortunately, cyber criminals have been able to leverage Power Shell for their attacks for years.
An online activation option was offered (like the actual Windows activation process), but was unavailable, requiring the user to call one of six international numbers to input a 6-digit code.
While the malware claimed that this call would be free, it was routed through a rogue operator in a country with high international phone rates, who placed the call on hold, causing the user to incur large international long distance charges.
