HIDING A FILE

                               We usually hide our private file in order to maintain privacy or to prevent it from observation by intruders. That hiding can be neither a file nor a folder. Some tips for hiding are as follows

          • General method for hiding files/folder without using any special software is to
             R/C the file --> Properties --> General tab --> Attrib [Hidden]

          • If you are working with MS office file and for more secured logging in to your more sensitive private information use
             Tool menu --> Options... --> Security tab --> Password to open  

          • For hiding[not displaying] the folder or naming a folder with no name use 
             R/C the folder  --> Rename --> Alt + 0160  & change icon picture to invisible 
(hold alt key until all numbers are pressed...)

The above mentioned methods are general methods for protecting our sensitive information, there are also a number of third party soft wares  that can be used for protecting our sensitive files ..:-)

Cryptovirology

Cryptovirology is the art of turning the methods designed to protect your data into a means of subverting it. The combination of virus science and cryptography created Cryptovirology. Cryptovirology is a field that studies how to use cryptography to design powerful malicious software. Even though Cryptography is the science of keeping data secure it can be combined with virus science to make an effective tool for hacking once system.

Cryptovirology can be said as the ‘Dark side of cryptography’. The aim of cryptovirology is to improve resistance of viruses to analysis. In this case we can also speak of “cryptoviranalysis”. The basic of cryptovirology was the observation of breaking the symmetry between ‘antivirus analyst view’ and ‘virus creator’s view’ about Virus using public key cryptography.

Cryptoviranalysis includes the analysis of cryptographic algorithms used by malware writers, attacks on the algorithms using automated methods (such as X-raying) and analysis of viruses and packers encryptors.
