<span style="font-family: Arial, Helvetica, sans-serif;">The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library. This weakness allows stealing the information protected, under normal conditions, by the SSL/TLS encryption used to secure it.</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;">You are likely affected if you configured and run an SSL-enabled website, meaning that you can access it using the https:// prefix instead of http://. You will need to patch the libraries in your system and replace the certificates and keys that may have been compromised. Please notice that remote access using ssh is NOT affected.</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;">OpenSSL versions from 1.0.1 through 1.0.1f (inclusive) are vulnerable and make it possible to steal information, including everything from the encrypted content and to the secret key used for the encryption. The attack is also indetectable.</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;">This security issue has been described in detail on the following page:</span><br />

<h2>
Method 1: Reset the Password</h2>
The easiest way to “hack” into someone’s Facebook is through 
resetting the password. This could be easier done by people who are 
friends with the person they’re trying to hack.<br>
<ul>
<li>The first step would be to get your friend’s Facebook email login. 
If you don’t already know it, try looking on their Facebook page in the 
Contact Info section.</li>
<li>Next, click on <strong>Forgotten your password?</strong> and type in the victim’s email. Their account should come up. Click <strong>This is my account</strong>.</li>
<li>It will ask if you would like to reset the password via the victim’s emails. This doesn’t help, so press <strong>No longer have access to these?</strong></li>
<li>It will now ask <strong>How can we reach you?</strong> Type in an email that you have that also isn’t linked to any other Facebook account.</li>
<li>It will now ask you a question. If you’re close friends with the 
victim, that’s great. If you don’t know too much about them, make an 
educated guess. If you figure it out, you can change the password. Now 
you have to wait 24 hours to login to their account.</li>
<li>If you don’t figure out the question, you can click on <strong>Recover your account with help from friends</strong>. This allows you to choose between three and five friends.</li></ul>

ADOLF HITLER : Sudut Kisah Yang Disembunyikan.

Dalam pencarian di internet aku terjumpa ayat ini <br>
<blockquote class="tr_bq">
Teringat kata-kata Hitler;<br>
<i><b>” Aku boleh bunuh semua Yahudi kalau aku mahu, tetapi aku tinggalkan sedikit supaya kamu kenal siapa mereka! “</b></i></blockquote>
<br>
Aku tertanya-tanya kenapa dia boleh berkata seperti ini.

How to detect operating system using user agent

In computing, a user agent is software (a software agent) that is acting on behalf of a user. For example, an email reader is a mail user agent, and in the Session Initiation Protocol (SIP), the term user agent refers to both end points of a communications session.<br />
<br />
In many cases, a user agent acts as a client in a network protocol used in communications within a client–server distributed computing system. In particular, the Hypertext Transfer Protocol (HTTP) identifies the client software originating the request, using a "User-Agent" header, even when the client is not operated by a user.<br />
<br />
<h1>
Standard User Agent browser</h1>
Most Web browsers use a User-Agent value as follows: <i>Mozilla/[version] ([system and browser information]) [platform] ([platform details]) [extensions]</i>. For example, Safari on the iPad has used the following:<br />
<br />
<pre>Mozilla/5.0 (iPad; U; CPU OS 3_2_1 like Mac OS X; en-us) AppleWebKit/531.21.10 
(KHTML, like Gecko)Mobile/7B405</pre>
The components of this string are as follows:<br />
<ul>
<li><i>Mozilla/5.0</i>: Previously used to indicate compatibility with the Mozilla rendering engine</li>
<li><i>(iPad; U; CPU OS 3_2_1 like Mac OS X; en-us)</i>: Details of the system in which the browser is running</li>
<li><i>AppleWebKit/531.21.10</i>: The platform the browser uses</li>
<li><i>(KHTML, like Gecko)</i>: Browser platform details</li>
<li><i>Mobile/7B405</i>: This is used by the browser to indicate 
specific enhancements that are available directly in the browser or 
through third parties. An example of this is Microsoft Live Meeting 
which registers an extension so that the Live Meeting service knows if 
the software is already installed, which means it can provide a 
streamlined experience to joining meetings.</li>
</ul>
Notable exceptions include Opera, which is a web browser, but does not include Mozilla in its User-Agent string.<br />
<br />
<h1>
Window User Agent</h1>
<pre>Mozilla/5.0 (Windows NT 5.1; rv:5.0) Gecko/20100101 Firefox/5.0</pre>
<ul>
<li><i>Windows NT 5.1; </i>: Window XP operating system as platform</li>

<li><i>MSIE 10.0</i>: Internet explorer version 10 as a browser</li>
<li><i>WOW64;</i>: A 32-bit window application is running on a 64-bit processor</li>
</ul>

How your Browser Speeds up Cross Domain Loading using DNS Prefetching

<strong>How it Works</strong><br>
What DNS prefetching does is attempt to resolve domain names before 
we, the  users, try to follow a link. This is accomplished using the 
computer's built-in  DNS resolution mechanism. Once a domain name has 
been resolved, if we do  navigate to that domain, there will be no 
effective delay due to DNS resolution  time. While downloading speed 
remains the same, looking up the IP address before  hand will save you 
an easily perceptible second or two when going from page to  page. A 
good example where DNS prefetching can really help is when a user is  
looking at a page with many links to various domains, such as a search 
results  page. When the browser encounters an a hyperlink that does not 
share the same  domain name as the current location, it first checks its
 cache and then, lacking  a cached copy, resolves the domain to the 
associated IP address through a  request from a DNS server. These 
requests happen in the background so as to not  block the rendering of 
the page. Moreover, since all this takes place in  parallel with the 
user's reading of the page, it places only a negligible load  on CPU and
 network resources. How much navigation time will a user save can  range
 from an average savings of about 200 milliseconds for non-cached 
content,  to one to two seconds for the worst DNS resolution delays.<br>
By default, prefetching of embedded link hostnames is not performed 
on  documents loaded over HTTPS. You can change this by setting the  
network.dns.disablePrefetchFromHTTPS browser preference to false.<br>

to be victimized, right?<o:p></o:p></div>
<div class="MsoNormal">
Beyond that, however, there are always best practices you
can adhere to so you can ensure that you are part of the fight against these
wireless broadband threats:<o:p></o:p></div>

<span style="font-family: "Arial","sans-serif"; mso-fareast-font-family: Arial;">●<span style="font-family: 'Times New Roman'; font-size: 7pt;">     </span></span><span dir="LTR"></span>Faithfully install and upgrade software, apps, games, and
anything installed in your device. These patches and updates are typically
offered free by providers, as they are also constantly fighting against
broadband threats.<o:p></o:p></div>
<div class="MsoNormalCxSpMiddle" style="margin-bottom: .0001pt; margin-bottom: 0in; margin-left: .5in; margin-right: 0in; margin-top: 0in; mso-add-space: auto; mso-list: l0 level1 lfo1; text-indent: -17.95pt;">
<span style="font-family: "Arial","sans-serif"; mso-fareast-font-family: Arial;">●<span style="font-family: 'Times New Roman'; font-size: 7pt;">     </span></span><span dir="LTR"></span>Always use a firewall. Your firewall is your sifter that screens
potentially dangerous information and stops it from ever going into your
computer or network. You have a network firewall and a computer firewall, at
the very least. You can control its settings to allow trusted data to always
pass through, which still provides sufficient flexibility for good security.<o:p></o:p></div>
<div class="MsoNormalCxSpMiddle" style="margin-bottom: .0001pt; margin-bottom: 0in; margin-left: .5in; margin-right: 0in; margin-top: 0in; mso-add-space: auto; mso-list: l0 level1 lfo1; text-indent: -17.95pt;">
<span style="font-family: "Arial","sans-serif"; mso-fareast-font-family: Arial;">●<span style="font-family: 'Times New Roman'; font-size: 7pt;">     </span></span><span dir="LTR"></span>Deploy an anti-virus. Anti-virus providers always try to keep
abreast of developments in the industry, and are always updating their
databases so your software always knows about the latest viruses or other threats
to your security.<o:p></o:p></div>

</span></span><span dir="LTR"></span>Use an Intrusion Detection
System (IDS). An IDS does exactly what it sounds like: it provides warnings
about potential attacks or illicit entries into your system. It can also
monitor critical areas of your computer or network.<o:p></o:p></div>
