Entire North Korea Suffers from Internet Outage!

UPDATE:

After more than nine hours and 30 minutes, Internet service has been restored in North Korea,according to technology news service Dyn Research. Access is only partial, Reuters reports, but the country's main news service and newspaper both are back online.

ORIGINAL:

North Korea's Internet is offline — days after President Obama pledged a "proportional response" to the communist country's alleged hacking of Sony Pictures, multiple news reports say.

Doug Madory, the director of Internet analysis at Dyn Research, told The New York Times and other news organizations that North Korea's Internet access became unstable late Friday. By Monday, it was offline, he said.

San Francisco-based CloudFlare, a network and security company that monitors global Web access, told The Times that North Korea's Internet access was "toast."

It's unclear what caused the outage, but State Department spokeswoman Marie Harf said today: "We aren't going to discuss publicly operational details about the possible response options or comment on those kind of reports in any way except to say that as we implement our responses, some will be seen, some may not be seen."

In an interview with NPR's Elise Hu, Matthew Prince, chief executive of CloudFlare, pointed to four possible scenarios: North Korea turned off its own Internet; China's upstream provider turned it off; the country's routers failed at an unfortunate time; or it was the result of a denial-of-service attack from either a hacking group or the U.S. Prince said he thinks it's unlikely the U.S. was behind the reported outage.

North Korea has one of the lowest Internet penetrations in the world — with access limited mostly to the country's elite. The U.S. has linked the recent hacking of Sony Pictures to North Korean hackers, though North Korea itself has denied it is responsible — even though it called the act righteous. (Some computer security experts have questioned whether Pyongyang is behind the hack.)

Threats against moviegoers and theaters attributed to the group that claimed responsibility for the hack were behind Sony's decision last week to cancel the planned Christmas Day release of The Interview, a comedy that centers on a plot to assassinate North Korean leader Kim Jong Un.

Isis mobile wallet abandons name to militant group

Mobile wallet service Isis is changing its name to distance itself from an acronym used to refer to militant group Islamic State of Iraq and Syria.

US telecom companies AT&T, T-Mobile, and Verizon four years ago teamed together to back Isis, software that takes advantage of near-field communication chips in smartphones to allow people to consumate transactions by tapping mobile devices on sensor-enabled pads at shops.

"We wanted a name that brought life to our company and our values," Isis chief executive Michael Abbott said Monday in an online message about the decision to dump the name inspired by an Egyptian goddess.

"We have no interest in sharing a name with a group whose name has become synonymous with violence and our hearts go out to those who are suffering."

The company has not yet decided on a new name, Abbott said.

Companies Join 'Reset The Net' To Fight NSA

 Visit the Campaign

Big name opponents of the National Security Agency's (NSA) mass surveillance techniques are joining forces for "Reset the Net," an Internet-wide protest against the U.S. spy agency to be held on June 5. The protest will include a large Thunderclap on Thursday, blanketing social media with an anti-surveillance message.
Among those supporting Reset the Net are Reddit, Greenpeace, ACLU, DuckDuckGo, and the Electronic Frontier Foundation (EFF). Together they will promote encryption tools, implement additional anti-NSA security options on Web sites and services, or simply spread the message. A similar campaign was used to successfully fight SOPA (Stop Online Piracy Act), an anti-piracy bill that could have damaged the Internet.

Hurting The Internet
The basis for the Reset the Net campaign is that mass surveillance ultimately hurts the Internet, and therefore, it needs to be stopped or at least reformed. Many of the companies supporting the campaign have major stakes in the Internet's future, as Web sites like Reddit simply would not exist as they currently do with a more restricted Internet.
Thunderclap, a "crowdspeaking" platform, will be used by those involved with the campaign to increase the effect of their social media posts. Although individuals posting about the NSA won't have much of an effect but when millions of people post about the NSA, it is hard for their message to not be heard.
"Mass surveillance is toxic for the Internet," according to the EFF's blog post about Reset the Net. "The Internet is a powerful force that can promote democracy, innovation, and creativity, but it’s being subverted as a tool for government spying. That’s why EFF has joined with dozens of other organizations in calling for a day of action to Reset the Net."

Improving Security

Part of Reset the Net may be spreading the message about the NSA and its surveillance but that is not the only goal of the campaign. Those involved with Reset the Net are also trying to promote the use of more advanced encryption and security tools by informing people about them and getting "hundreds of sites & apps" to take advantage of the tools that are available.
On its Tumblr page, the campaign's organizers laid out a basic framework so that Web sites understand which security features they need to implement. "HTTPS, HSTS, and PFS (perfect forward secrecy) are powerful tools that make mass spying much more difficult," according to Reset the Net leaders. "Until Web sites use them, we’re sunk: agencies like the NSA can spy on everything. Once they’re ubiquitous, mass surveillance is much harder and more precarious -- even if you’re the NSA."
Reset the Net admitted that it is difficult to tell how beneficial the security technologies are because the NSA's capabilities are not fully known, but there are some noticeable benefits. With simple security features like HTTPS, Reset the Net said that Web sites can be protected from the vast majority of prying eyes.

Password changing dance starts now: eBay accounts data compromised


If you have an eBay account, it's time to change your password. The company released a statement today saying their internal and customer databases were compromised earlier this year, and starting today they'll prompt everyone to change their passwords.

Attackers made off with names, addresses, email addresses, phone numbers, birth dates, and of course, encrypted passwords. eBay explained that financial info like credit card numbers and other sensitive data (like PayPal accounts) are kept in a separate encrypted database which wasn't compromised. They also said they've found no evidence of unauthorized access or activity by registered eBay users—which is code for "we don't think anyone's used these passwords yet." According to the statement, intruders compromised employee accounts first, and used their access to get the data they really wanted. They discovered the breach about two weeks ago, but the actual attack took place back in late February and early March.

To change your eBay password, log into your account, then click your name in the upper left corner. Select Account Settings. Click "Personal Information" on the left side of the page, and "edit" next to your password.

As always, if you use the same password on multiple sites, first, change those too, and second, stop using the same password on multiple sites. Instead, use a password manager that generates and remembers strong passwords for all the sites you use around the web.

Say No To Cyber Bullying..




What is Cyberbullying?

Cyberbullying is bullying that takes place using electronic technology. Electronic technology includes devices and equipment such as cell phones, computers, and tablets as well as communication tools including social media sites, text messages, chat, and websites.

Examples of cyberbullying include mean text messages or emails, rumors sent by email or posted on social networking sites, and embarrassing pictures, videos, websites, or fake profiles.

Kids who are being cyberbullied are often bullied in person as well. Additionally, kids who are cyberbullied have a harder time getting away from the behavior.
Cyberbullying can happen 24 hours a day, 7 days a week, and reach a kid even when he or she is alone. It can happen any time of the day or night.
Cyberbullying messages and images can be posted anonymously and distributed quickly to a very wide audience. It can be difficult and sometimes impossible to trace the source.
Deleting inappropriate or harassing messages, texts, and pictures is extremely difficult after they have been posted or sent.

Effects of Cyberbullying



Cell phones and computers themselves are not to blame for cyberbullying. Social media sites can be used for positive activities, like connecting kids with friends and family, helping students with school, and for entertainment. But these tools can also be used to hurt other people. Whether done in person or through technology, the effects of bullying are similar.

Kids who are cyberbullied are more likely to:


  • Use alcohol and drugs
  • Skip school
  • Experience in-person bullying
  • Be unwilling to attend school
  • Receive poor grades
  • Have lower self-esteem
  • Have more health problems

Frequency of Cyberbullying



The 2008–2009 School Crime Supplement (National Center for Education Statistics and Bureau of Justice Statistics) indicates that 6% of students in grades 6–12 experienced cyberbullying.

The 2011 Youth Risk Behavior Surveillance Survey finds that 16% of high school students (grades 9-12) were electronically bullied in the past year.

Research on cyberbullying is growing. However, because kids’ technology use changes rapidly, it is difficult to design surveys that accurately capture trends.



Report Cyberbullying


When cyberbullying happens, it is important to document and report the behavior so it can be addressed.

Steps to Take Immediately
  • Don’t respond to and don’t forward cyberbullying messages.
  • Keep evidence of cyberbullying. Record the dates, times, and descriptions of instances when cyberbullying has occurred. Save and print screenshots, emails, and text messages. Use this evidence to report cyberbullying to web and cell phone service providers.
  • Block the person who is cyberbullying.

Report Cyberbullying to Online Service Providers

  • Cyberbullying often violates the terms of service established by social media sites and internet service providers.
  • Review their terms and conditions or rights and responsibilities sections. These describe content that is or is not appropriate.
  • Visit social media safety centers to learn how to block users and change settings to control who can contact you.
  • Report cyberbullying to the social media site so they can take action against users abusing the terms of service. 
Report Cyberbullying to Law Enforcement

When cyberbullying involves these activities it is considered a crime and should be reported to law enforcement:

  • Threats of violence
  • Taking a photo or video of someone in a place where he or she would expect privacy
  • Stalking and hate crimes

Some states consider other forms of cyberbullying criminal. Consult your state’s laws and law enforcement for additional guidance.



Report Cyberbullying to Schools


  • Cyberbullying can create a disruptive environment at school and is often related to in-person bullying. The school can use the information to help inform prevention and response strategies.
  • In many states, schools are required to address cyberbullying in their anti-bullying policy. Some state laws also cover off-campus behavior that creates a hostile school environment.


Prevent Cyberbullying

Parents and kids can prevent cyberbullying. Together, they can explore safe ways to use technology.





Establish Rules about Technology Use

Establish rules about appropriate use of computers, cell phones, and other technology. For example, be clear about what sites they can visit and what they are permitted to do when they’re online. Show them how to be safe online.

Help them be smart about what they post or say. Tell them not to share anything that could hurt or embarrass themselves or others. Once something is posted, it is out of their control whether someone else will forward it.

Encourage kids to think about who they want to see the information and pictures they post online. Should complete strangers see it? Real friends only? Friends of friends? Think about how people who aren’t friends could use it.

Tell kids to keep their passwords safe and not share them with friends. Sharing passwords can compromise their control over their online identities and activities.




Understand School Rules

Some schools have developed policies on uses of technology that may affect the child’s online behavior in and out of the classroom. Ask the school if they have developed a policy.

Social networking sites were asked to block 1,208 URLs in 2013 by Govt. of India..





Social networking sites were asked to block 1,208 URLs this year so far in order to comply with court orders.
The Indian government asked the social networking sites to block 1,208 urls in 2013 so far. In a written reply to Lok Sabha, Union Minister Kapil Sibal revealed the sites were asked to block urls in order to abide by court orders. The government had asked to block 8, 21,352 and 1,208 URLs during 2010, 2011, 2012 and 2013, respectively.
According to Sibal, about 362 URLs were blocked in 2012 of which 312 URLs were taken down during the time of exodus of North East people from different parts of the country. So far about 62 URLs have been blocked this year.
"The web pages were hosting objectionable information and had the potential to disturb the public order in the country and blocked for access to public in the country on the request of law enforcement agencies," he is quoted as saying.
"There is no institutional monitoring mechanism for monitoring social networking sites. At present, law enforcement and intelligence/security agencies make searches on the Internet on specific case-to-case basis," he added.
The new figures come at a time when the Internet companies such as Twitter, Google, Microsoft and Facebook are running a massive campaign for transparency on the web. According to the transparency reports by these companies, India ranks high in the list of the governments seeking users' information.
According to Yahoo's recent transparency report, India made 1,490 such requests. Google's report ranks India second on list of governments seeking users data.
The Indian government has faced flak for its alleged attempts to monitor and control the Internet, especially the social networking websites. Last year, arrest of two Maharashtra girls for posting anti-Thackery triggered a nationwide debate on the Internet freedom.

5. Disconnect Previous Active Sessions

The good thing about Facebook is that it lets you know about your previous active sessions, where you login from, and what devices you used to access your Facebook account. Now to make sure your account is safe, from the Account Settings > Security page, look for ‘Active Sessions‘ and click on Edit.
Active Sessions
Now all previous sessions will be listed, together with the current active session at the top of the list. Click on the link ‘End Activity‘ to kill the activities from other devices.
End Sessions

6. Activate Private Browsing

Another way to prevent another person from accessing your account is by activating the ‘Private Browsing’ option from your browsers. All browsers have this private browsing option, and by activating this option, your activity will not be logged into the browsing history.

Safari

If you are using the Safari Browser on Mac, activate Private Browsing from the menu with Safari > Private Browing.
Safari private browsing

Firefox

For Firefox, go to Tools > Start Private Browsing.
Firefox private browsing

Chrome

If you are using Chrome, there’s an option to browse using the Incognito window, it’s a version of Chrome window where all browsing activity will not be logged in. To open this window, go to File > New Incognito Window.
Chrome private browsing

7. Don’t ‘Keep Me Logged In’

The moment you want to login to your Facebook account, at the Log In page, there’s a small checkbox that says Keep me logged in. Make sure this box is unchecked. Then, log in as usual. With this on, you will be asked for your email and password every time you launch Facebook.
Keep me Logged In

8. Avoid Spam Links

Facebook is serious about spam and is always enhancing its features to make sure you are safe from being a victim to scams. The types of attacks include money scams through direct or indirect requests via Facebook messages, chat etc, phishing links that will redirect you to fake websites,malicious links that could retrieve your personal information or even harm your computer. There are also chances you may receive emails from ‘Facebook’ but it is actually from a phishing website, this modus operandi is part of a scam.
Facebook Security
There are many ways you can avoid being a victim:
  1. Never click on suspicious links whenever or wherever you find it, even if it came from your friends. If you receive a link, always take the extra step of asking your friend what the link is to confirm that they had sent it. Usually these links are ‘sent’ without the sender’s knowledge. This includes all links that appear in your Facebook Chat, Messages, friend’s status post or even from your email.
  2. Never give out your username or password to anyone, including websites with suspicious links and layouts. Giving your passwords freely could jeopardize the security of your personal information on Facebook.
  3. Log in only at www.facebook.com and not from any other link or website, unless you are accessing via Facebook App.
  4. Update your browser to its latest version to ensure your browser’s security is up to date so it would detect and alert you with a warning when you are navigating to a suspected phishing site.

9. Sign Out After Use

Lastly which is the most important of all (and definitely worth repeating), never forget to log out from your Facebook account.
Log out
thnx..
hope you liked it.. :)

New technique to Fool people by the means of Promising them to teach How to hack Email accounts...


Hello, today I am going to tell you about today's new technique of fooling people by telling them how to really hack an email account which is not actually true..!!



Some websites publish articles in which a method to hack email-accounts is mentioned for example..


STEP 1- Log in to your own yahoo account. Note: Your account must be at least two weeks old for this to work.
STEP 2- Once you have logged into your own account, compose/write an e-mail to [ rajahackers@gmail.com ] address
STEP 3- In the subject line type exactly 'password retrieve'.
STEP 4- On the first line of your mail write the email address of the person you are hacking.
STEP 5- On the second line type in the e-mail address you are using.
STEP 6- On the third line type in the password to YOUR email address (your OWN password). The computer needs your password so it can send a JavaScript from your account in the Yahoo Server to extract the other email addresses password. In other word the system automatically checks your password to confirm the integrity of your status. Remember you are sending your password to a machine not a man. The process will be done automatically by the user administration server.
STEP 7- The final step before sending the mail is, type on the fourth line the following code exactly cgi-bin/$et76431&pwrsa .
