How to protect your online passwords, a lesson from Sarah Palin

image In recent news the Internet is talking about how a college guy hacked Sarah Palin, 2008 USA vice president candidate, personal Yahoo email account. Actually there was no technical scripting or coding involved in this hack issue. What the “hacker” did was to use Yahoo’s password recovery function by answering 3 security questions. For example, Sarah Palin set up the following three security questions to help her retrieve forgotten password (actually pre-set by Yahoo!). 1), what is her birth date; 2), what is her house zip code; 3), where did she meet with her husband; In the event of her forgetting her email password, what she needs to do is to answer these three questions and reset the password.

Hack the Wi-Fi network of Atlanta Airport is the old news

image Sometimes it is very funny to see how the Internet work. The Internet is great with its powerful penetration degrees, it can reach to anyone, anywhere and anytime. That is why we are happy to get all these unlimited information we need from the Internet. But if we did not pay attention to the information date, things will be different. I remember weeks ago, a undated news about one Airline merging had been ranked top in Google News even it was an old news. But this news item caused the stock market moving crazy for a while because people thought this airline would talk acquisition again.

But of course, today I am here not talking about something like that crazy. I just wanted to mention one blog post which has been pop-up on the Internet recently and referred to me by co-workers a couple of times.

This blog is about Hacking a commercial airport WLAN with a simple Image handler manipulation. It is great since everybody wants Free Wi-Fi. That is why it was becoming popular in digg and introduced in Lifehacker blogs. But everyone was just blindly excited and forgot the most important thing: check the publish date of this blog!

How to get back the default admin access to HP Web Jetadmin

HPChallenge: This afternoon, a co-worker came to me and ask my help to retrieve her forgotten admin password for HP Web JetAdmin login. The situation was that she had been using another created profile too often to remember the default admin account logon credential. She tried the default password ‘admin’ but it did not work.

First, I asked whether this software uses any database to store password since I thought we can open any database tables. She said there was a MS SQL server installed on the server but she did not think we are using the database server now.

Then I figured it might use the flat file to store such user credential information, even I trusted such big company as HP would not do so. But anyway, I asked to take a look at the Web Jetadmin server. And I hope I can figure something more out from the web server logon script.
