Over on security blog Bleeping Computer, there is a post about a new type of ransomware that presents a triple threat. Known as RAA, what makes this one different is that instead of using an .exe attached to an email which would pop up an alert when a user tried to run it, this one is written entirely in JavaScript, a language often used to encode and provide functionality for web pages, and if a user runs something written in JS it likely would not pop up any alerts, and the damage would be done before you knew it.

New, dangerous ransomware appears in the wild

In class we talked briefly about ‘Ransomware,’ software that compresses / encrypts / locks up your files, then demands payment for the password or key or whatever to get your files back. We also discussed that the amounts of money demanded are never too much to prevent someone from actually paying – if they asked for a million dollars no one would pay it, and the encryption was normally breakable if you knew what you were doing.

Now, in an event that involves many of the topics we discussed in our last class, a scary new ransomware attack is changing all that. Known as OphionLocker (this article shows it may not be as sophisticated as everyone is saying, possibly breakable through a C++ IDE ), it uses what is known as elliptic curve cryptography, a practically unbreakable form of encoding, to hold files hostage, and it is delivered through malicious ads displayed on web pages.
