A new variety of Ransomware has been discovered by Trojan7Malware researchers. Dubbed as OphionLocker, this Ransomware is very unique in the sense that it uses elliptic curve cryptography for file encryption, and Tor for communication. Another unique signature of OphionLocker is that it uses malvertising campaigns to propagate itself rather then traditional spear phishing methods.. Elliptic Curve Cryptography Elliptic curve cryptography (ECC) is a public-key cryptography based on the algebraic structure of elliptic curves over finite fields. One of the main benefits ECC cryptography is that it provides same level of encryption with smaller size of keys. The link for this article located at TechWorm is no longer available. .

Elliptic Curve Cryptography (ECC) is a public key cryptography. In public key cryptography each user or the device taking part in the communication generally have a pair of keys, a public key and a private key, and a set of operations associated with the keys to do the cryptographic operations. Only the particular user knows the private key whereas the public key is distributed to all users taking part in the communication. Some public key algorithm may require a set of predefined constants to be known by all the devices taking part in the communication. ?eDomain parameters?f in ECC is an example of such constants. Public key cryptography, unlike private key cryptography, does not require any shared secret between the communicating parties but it is much slower than the private key cryptography. . The mathematical operations of ECC is defined over the elliptic curve y2 = x3 + ax + b, where 4a3 + 27b2 ? The link for this article located at Info Sec Writers is no longer available. .

Sun's "elliptic curve" technology is involved in the process of using keys to encrypt and decrypt information for electronic transactions. Such encryption lets people buy products online, for example, while shielding their credit card number from prying eyes. The Santa Clara, Calif.-based server seller donated the technology to the OpenSSL project, a programming group that makes an open-source version of the Secure Sockets Layer (SSL) encryption system. Elliptic curve cryptography will enable secure communications with devices that don't have as much calculating power as most desktop computers, said Whitfield Diffie, Sun's chief security officer and a pioneer of the Diffie-Hellman "public key" cryptography method used today in SSL and other encryption systems. Diffie spoke Thursday during a news conference at the SunNetwork conference here. The link for this article located at cnet.com is no longer available. .
