This Report is not recent, but is very interesting under many aspects:
- Well designed Analysis Approach for a Generic CryptoTarget
- Concrete Cryptanalysis and successive Attack
- Evidence of Badly Designed Conceptual and Logical Crypto Architecture
In this report, we
point out a serious security flaw in Microsoft Word and Excel. The
stream cipher RC4 [9] with key length up to 128 bits is used in
Microsoft Word and Excel to protect the documents.

There are some places in the world where life is dangerous. Internet has some dark zones too and RBN is one of them. RBN stands for Russian Business Network and it’s a nebulous organisation which aims to fulfill cybercrime.
This study aims to provide some enlightenment on RBN activities and tries to give details how they work. Indeed RBN has many constituents and it’s hard to have an exact idea on the goal of some of them and the way they’re linked with other constituents. There are some countermeasures available but they don't make sense for home users or even companies.

Report on the publications from the 8th of October to the 4th of December.
A novel public key crypto system based on semi-modules over quotient semi-rings
(Reza Ebrahimi Atani, Shahabaddin Ebrahimi Atani, Sattar Mirzakuchaki)
Abstract.
In A generalization of the original Diffie-Hellman key exchange in (ℤ/pℤ)* found a new depth when Miller and Koblitz suggested that such a protocol could be used with the group over an elliptic curve.

The following is an interview to Elia Florio, a Symantec Security
Response Engineer, about the interactions between two apparently
disjoint areas: cryptography and virology.
In particular, this work
originates from the idea that, in a practical context, it is appreciable to have feedbacks from the wild, instead of being limited
to a theoretical model. And it's just because of the chaos present in
the security outlook that I thought it was useful to show the
confluence points of these two subjects, giving particular attention
to their implementations.
I would like to thank Elia Florio for his precious collaboration, and
Andrea Lelli for his help.
Keywords: cryptography, cryptovirology, polymorphic virus, crypto-counters, ransomwares

Fermath: how to cooperate
This post is the instantaneous result of the previous one titled "wind of change". As one of our readers suggested, I think that is important to encourage people in getting involved in some collaboration.
Our goal is to provide and gather information about the cryptology field.
Maybe one may think: "Yes, interesting. But I don't know exactly what to do in order to cooperate.. uhm, I will write them... TOMORROW!" or also one may not have something to propose etc. etc. The only thing I presume is that some visitors are really interested in this area. So, here I will expose what I really mean with the verb "cooperate".
