Cryptovirology

August 20, 2007

CryptovirologyYo, Thats My Seminar Topic!!

Cryptovirology is a field that studies how to use cryptography to design powerful malicious software. Like the notion??!! moi aussi..

I went thru some papers and collected information about it…I got some “C” implementations too ( which I would like to execute it at my college’s computer ;) )



Placement Update: From around 40 who cleared the written exam, 12 finally made it to Cisco!!! With the whooping 8 lpa, they must be elated!!

TB, BugMeNot

August 18, 2007

Well these are not the names of Diseases!!

Its Thunderbird..Mozilla’s open source desktop email client… I am using it since 1 week and its quite gud!!

There is a separate option for configuring gmail, unlike outlook express(which I used earlier), which comes very handy… it automatically saves my sent mails to the gmail outbox too…There are great themes, plugins which make it a versatile email client!!

Overall Thunderbird is a polished email client with attaractive looks,easy to operate and yes it is free opensource software ;) So, when are you switching to it??!!

There is something more interesting I found… Its called BugMeNot…Use this to Access and share logins for websites that require you to register in order to view content..

It comes as a plugin for Firefox as well as Opera. Do give it a try!!

ctrl+alt+del

May 22, 2007

I remember in one of our labs when I wrote a c++ program which gets computer hanged (actually i was writing my lab program and due to some error the comp hanged; but let it be a secret, an open secret)…

By luck or by badluck the teacher was around when i did this..he just whispered, “press those 3 keys.” Yes we are talking about ctrl+alt+del.. now let me come straight to the point.

I saw an interesting video starring David Bradley. He is explaining how and when he invented the keystroke ctrl-alt-del, but there is something more to look for..

Enjoy the video Bill Gates Gets Mocked on Panel ;)

Passwords

March 24, 2007

Passwords can be very important sometimes… I couldn’t stop myself laughing on the idea of keeping the same password for all the email ids or any other account one has.. especially if the person belong to computer science field.. :) lol…

Coming to the lesser funny part of it… if you think you are making your job of remembering the passwords easier by keeping it same everywhere, think again!!!

this can take serious turns if you are attacked by social engineering… remember you are responsible for the security of your emails…

Being related to web I would like to discuss something on the encryption of the passwords… even if your password looks something like coccidioidomycosis, it is not hidden from administrators who work at the Web hosting company where your database is hosted.. here encryption techniques bocome instrumental..

Scrambling the passwords using some home-brewed algorithm may add some obscurity but not true “security.” Another approach would be to encrypt all passwords in your database using some industry-standard cipher, such as the Message-Digest Algorithm 5 (MD5).

MD5 encryption is a one-way hashing algorithm. Two important properties of the MD5 algorithm are that it is impossible to revert back an encrypted output to the initial, plain-text input, and that any given input always maps to the same encrypted value. This ensures that the passwords stored on the server cannot be deciphered by anyone. This way, even if an attacker gains reading permission to the user table, it will do him no good.

Read more on how to go about this here..

Things dont work the way we might see it… ;)
