Risks and threats by using chatting applications..

Security risks by using chatting applications:

                      Crackers or blackhat hackers have consistently used IM networks as vectors for
             delivering phising attempts, poison URLs and virus-laden file attachments. For ex: IM used
             to infect computers with spyware,viruses,trojans and worms.
                      
                      In addition to the malicious code threats, the use of instant messaging at works also
             creates a risk of non-compliance to laws and regulations governing the use of electronic
             communications in business.

                     Organisations of all types must protect themselves from the liability of their employees
             inappropriate use of IM. The informal, immediate and ostensibly anonymous nature of  
             instant  messaging makes it a candidate for abuse in the workplace.
   
                     Cyber criminals hide their identity through false name and age. Even grown up people
             may pretend to be a child/teenager.

Tips for make yourself secure:
                      
         1/ Be care full before choosing an online friend. Try to not reveal all your personal details
             to whome you meet online. Use nickname for yourself and hide your personal details from
             stranger.

        2/  Take your time and make sure that you are sending it to right address. Also cross check
              if you are chatting with the right person who is responsible enough to access those details.

        3/  Do not open the spam messages as it might inject malicious code into your pc. Always use
             updated IM and firewall versions. Be conscious before clicking on the link because it may
             contain spyware.

Know more about CAPTCHAs...............Definition and Applications....

...??? What actually CAPTCHAs Are??????

A CAPTCHA is a program that can generate and grade tests that humans can pass but current computer programs cannot. For example, humans can read distorted text as the one shown below, but current computer programs can't:

CAPTCHA example
                           
The term CAPTCHA (for Completely Automated Public Turing Test To Tell Computers and Humans Apart) was coined in 2000 by Luis von Ahn, Manuel Blum, Nicholas Hopper and John Langford of Carnegie Mellon University. At the time, they developed the first CAPTCHA to be used by Yahoo.

In other words,  a CAPTCHA is a type of challenge-response test used in computing as an attempt to ensure that the response is generated by a human being. The process usually involves a computer asking a user to complete a simple test which the computer is able to grade. These tests are designed to be easy for a computer to generate but difficult for a computer to solve, but again easy for a human.


                                           Applications of CAPTCHAs

Protecting Website Registration:  Several companies (Yahoo!, Microsoft, etc.) offer free email services. Up until a few years ago, most of these services suffered from a specific type of attack: "bots" that would sign up for thousands of email accounts every minute. The solution to this problem was to use CAPTCHAs to ensure that only humans obtain free accounts. In general, free services should be protected with a CAPTCHA in order to prevent abuse by automated programs.

Preventing Comment Spam in Blogs: Most bloggers are familiar with programs that submit bogus comments, usually for the purpose of raising search engine ranks of some website (e.g., "buy penny stocks here"). This is called comment spam. By using a CAPTCHA, only humans can enter comments on a blog. There is no need to make users sign up before they enter a comment, and no legitimate comments are ever lost!

Preventing Dictionary Attacks: CAPTCHAs can also be used to prevent dictionary attacks in password systems. The idea is simple: prevent a computer from being able to iterate through the entire space of passwords by requiring it to solve a CAPTCHA after a certain number of unsuccessful logins.

Worms and Spam: CAPTCHAs also offer a plausible solution against email worms and spam: "I will only accept an email if I know there is a human behind the other computer." A few companies are already marketing this idea.

Search Engine Bots: It is sometimes desirable to keep webpages unindexed to prevent others from finding them easily. There is an html tag to prevent search engine bots from reading web pages. The tag, however, doesn't guarantee that bots won't read a web page; it only serves to say "no bots, please." Search engine bots, since they usually belong to large companies, respect web pages that don't want to allow them in. However, in order to truly guarantee that bots won't enter a web site, CAPTCHAs are needed.

Online Polls:  In November 1999, http://www.slashdot.org released an online poll asking which was the best graduate school in computer science (a dangerous question to ask over the web!). As is the case with most online polls, IP addresses of voters were recorded in order to prevent single users from voting more than once. However, students at Carnegie Mellon found a way to stuff the ballots using programs that voted for CMU thousands of times. CMU's score started growing rapidly. The next day, students at MIT wrote their own program and the poll became a contest between voting "bots." MIT finished with 21,156 votes, Carnegie Mellon with 21,032 and every other school with less than 1,000. Can the result of any online poll be trusted? Not unless the poll ensures that only humans can vote.

A glance at MALWARES around us....................

MALWARES:------  INTRODUCTION,  CLASSIFICATION,  & TIPS FOR BEING SECURE......

INTRODUCTION: WHAT IS A MALWARE?????????????????
              
                                A malware is a malicious software designed to harm a computer system without
                                the owner's informed consent. Malware  software, is software used or 
                                programmed by attackers to disrupt computer operation, gather sensitive 
                                information, or gain access to private computer systems. It can appear in the  
                                form of code, scripts, active content, and other software. Malware is a general 
                                term used to refer to a intrusive software.Malware includes computer viruses, 
                                worms, Trojan horses, rootkits, spyware, dishonest adware,crimeware and other 
                                malicious and unwanted software.Around 80% of malware today is designed to 
                                steal and find confidential information stored on your computer.This type of 
                                malware is sometimes called crimeware.Malware can invade your machine 
                                through infected email attachment, "bots" that crawl the internet looking for 
                                unprotected computers.


MLWARE CLASSIFICATIONS:     TYPES AND DESCRIPTIONS......................

                                VIRUS:  A virus is a program which is able to replicate and attach itself to a
                                               program or files infecting the system without your knowledge.This are 
                                               the software programs that hide on your computer and cause its
                                              damage
                                             .

                               Spyware:  Spyware is a malicious software program that hides on your computer,
                                                 tracks what you are doing online, and sends that information over the 
                                                internet.Some types of softwares like keyloggers can records what you 
                                                are typing in your computer and lot others you can't imagine.

                        Trozan horse:   For a malicious program to accomplish its goals, it must be able to 
                                                 run without being detected, shut down, or deleted. When a malicious
                                                 program is disguised as something normal or desirable, users may 
                                                 willfully install it without realising it. This is the technique of the  
                                                 Trojan horse or trojan. A Trojan horse is any program that invites the 
                                                 user to run it, concealing harmful or malicious code. The code may 
                                                 take effect immediately and can lead to many undesirable effects, such 
                                                 as deleting the user's files or installing additional harmful software.

                              Rootkits:    Once a malicious program is installed on a system, it is essential that 
                                                 it  stay concealed, to avoid detection. Techniques known as rootkits
                                                 allow this concealment, by modifying the host's operating system so 
                                                 that the malware is hidden from the user. Rootkits can prevent a
                                                malicious process from being visible in the system's list of processes, 
                                                or  keep its files from being read.

                                   

                                        
  TIPS TO SECURE:        
                                     * Set the browser to open the webpages only from the trusted web sites.
                                      
                                     * Always checks for the extension of a file and always scan any attached files
                                       before using it.

                                     * Always scan the removable mediums before you open.

                                     * Avoid downloading the files with double extension.

                                     * Always use anti-virus software and also update its signature database when 
                                       available.
         
                                     * Try to avoid the attachment from unknown users.
