"Need Help" Threats On Popular Social Networking Sites !!

0 comments
If you're on Facebook, Twitter, myspace or any other social networking site, you could be the next victim. It will come to you as a friendly package..it starts with a friend updating his or her status and slowly raveled his/her cruel intentions. FBI alerts..!!
That's because more cyberthieves are targeting increasingly popular social networking sites that provide a gold mine of personal information, according to the FBI. Since 2006, nearly 3,200 account hijacking cases have been reported to the Internet Crime Complaint Center, a partnership between the FBI, the National White Collar Crime Center and the Bureau of Justice Assistance.

It starts with a friend updating his or her status or sending you a message with an innocent link or video. Maybe your friend is in distress abroad and needs some help.All you have to do is click.

When the message or link is opened, social network users are lured to fake Web sites that trick them into divulging personal details and passwords. The process, known as a phishing attack or malware, can infiltrate users' accounts without their consent.
Once the account is compromised, the thieves can infiltrate the list of friends or contacts and repeat the attack on subsequent victims. Social networking sites show there is ample opportunity to find more victims; the average Facebook user has 120 friends on the site.

"Security is a constant arms race," said Simon Axten, an associate for privacy and public policy at Facebook. "Malicious actors are constantly attacking the site, and what you see is actually a very small percentage of what's attempted."
As some social networking sites experience monstrous growth, they are becoming a new -- and extremely lucrative -- frontier for cybercrime. Facebook says it has 300 million users, nearly the size of the U.S. population, and it continues to attract users outside the college student niche. From February 2008 to February 2009, Twitter, a micro-blogging site where users post 140-character messages known as tweets, grew 1,382 percent to more than 7 million users.

"They [cybercriminals] are very adept to using social engineering," said Donald DeBold, director of threat research for CA, an Internet security company. "Your friend is in trouble traveling in another country, 'I lost my wallet. I need help.' They exploit the curiosity aspect out of human nature."

A few decades ago, malicious software and viruses were usually the result of a prank, but Internet security experts say today's attacks are profit-driven. A study from the Indiana University in 2005 discovered that phishing attacks on social networks operated with a 70 percent success rate. These users had fallen for the scam, opened the foreign link and released personal information.

Cybercriminals are employing phishing and malware attacks for a number of reasons, including trying to redirect users to sites where profit is fueled by the number of visitors. They also try to elicit private information like passwords and bank account numbers to perform scams.

Early this year, Twitter experienced several phishing attacks in which a Web page that looked identical to the widely recognized light blue Twitter page was a hoax. The company warned users to double-check the URL to ensure they were visiting the correct site.

The Internet Crime Complaint Center received more than 72,000 complaints about Internet fraud in 2008 that were referred to law enforcement agencies for further investigation. These cases involved financial losses amounting to $264.6 million, an increase from 2007. Each person lost an average of $931.

"Most of us would want to help a friend in need, but if it's an online friend, and they want you to wire money, you should double-check," FBI spokesman Jason Pack said.

Security experts said it makes sense that cybercriminals are turning to social networking sites. Personal information is abundant on sites like Facebook and MySpace. Each time users give out valuable information like birth dates or addresses, they could be providing hints about their password, security experts say.

The American Civil Liberties Union has expressed concern about the information visible through Facebook quizzes and applications.

"They'll have access to all that information, so they can sell it, they can share it, they can do an awful lot with it," Chris Calabrese, legislative counsel for privacy-related issues with the ACLU, told CNN.com in September.

Many Internet security experts consider the first virus attack on the PC to have occurred in 1986. By the early 1990s, viruses transmitted on floppy disks became ubiquitous. When the World Wide Web became widely available that same decade, viruses, worms and malware became problems in e-mail accounts, frustrating users who clicked on messages thought to be legitimate.

In the new millennium, the most common form of malware attack has become known as drive-by downloads. While surfing on Google or Yahoo, spyware or a computer virus is automatically and invisibly downloaded on a computer, requiring no user interaction for the computer to be infected.

"We are on the verge from shifting from the Web being the No. 1 victim of infecting to social network," said Mikko H. Hypponen, chief of research technology at F-Secure Corp. His company sells anti-virus software and malware protection programs. "It's going to get a lot worse before it gets better."

Social networks are fighting the aggressive attacks from cybercriminals. Most sites have information pages dedicated to educating users about the risks of Internet scams. Users can become a fan of "Facebook Security" and receive updates on how to protect their accounts. One of the most common pieces of advice given by security experts is to change passwords frequently.

Facebook has also developed complex automated systems that detect compromised accounts. They spot and freeze accounts that are sending an unusually high number of messages to their friends. Company security officials said Facebook is a closed system, which can be helpful in erasing phony messages from all accounts.

At News Corporation's MySpace.com, the company creates blacklists of phony accounts to prevent people from clicking on a faulty link. Hemanshu Nigam, first chief security officer for MySpace, said the firm warns about suspicious links and educates users about the harm phishing and malware attacks can bring.

"We are prepared for them," he said.

Here are few easy steps How to protect yourself against scams:
(Information provided by FBI and Internet security experts)

1. Change your passwords frequently

2. Adjust Web site privacy settings

3. Be selective when adding friends

4. Limit access to your profile to contacts you trust

5. Disable options such as photo sharing

6. Be careful what you click on

7. Familiarize yourself with the security and privacy settings

8. Learn how to report a compromised account

9. Use security software that updates automatically

Largest Virus Threat Awaited (9 Million +)

0 comments
MILLIONS of computers around the world could go into meltdown on April 1 because of a deadly virus.

The Windows worm called Conficker could give a hacker unrestricted access to every infected machine on the planet.

And the aggressive bug could be hiding on your PC at home right now, waiting to kick in.

For the hackers, it’s like having a virtual army at their fingertips.

The criminals behind it have the power to launch a tidal wave of junk emails, bringing computers grinding to a halt.

They could also plunder information, including your bank details.

But the truth is that the best techie brains in the business just don’t know exactly what the hackers have in mind.

Infected:

Virus expert Mikko Hypponen, from the firm F-Secure, said: “It is scary thinking about how much control a hacker could have over all these computers. They would have access to millions of machines.”

Microsoft, who developed the Windows computer operating system, have slapped a £175,000 bounty on whoever is responsible, so far without success.

The sophisticated Conficker bug — also known as Downadup or Kido — targets systems via the web and can be spread on memory sticks.

More than nine million computers were infected at the bug’s peak last month.

And if Conficker is still on your system come Wednesday, you could be in trouble.

Once inside your PC, it sets up files and starts downloading information from a controlling “boss” server.

Finding that website and the mastermind behind it all is like looking for a needle in a haystack.

That is because the bug creates hundreds of bogus addresses every day to put investigators off the scent.

The infected PCs then form a network and “talk” to each other, updating and evolving.

The bug even attacks anti-virus software and other files on your computer to strengthen its position.

And it resets “restore” points, making recovery of your old system even harder.

The first of three Conficker strains was discovered in November last year.

A second, more aggressive strain followed in December and a third this month. This contains the all-important April 1 trigger.

Trigger :

To avoid infection, Windows users must download a special free update “patch” from the Microsoft website. But that isn’t enough — you also need good anti-virus software too.

Many businesses around the world are thought also to be at risk after failing to update systems.

Graham Cluley, from computer security firm Sophos, warned: “Microsoft did a good job of updating people’s home computers.

“But the virus continues to infect businesses that have ignored the update.”

He also stressed the need for strong passwords on your computer, adding: “If users are using weak passwords — 12345, QWERTY etc — then the virus can crack them.”

F-Secure’s Mikko warned potential problems with Conficker would be highlighted wildly before April 1.

But he said he didn’t foresee an attack, despite the fears and mystery surrounding the problem.

He said: “There’s always hype — just think of previous cases.

“There is not going to be a ‘global virus attack’. We don’t know what they are planning to do, if anything.

“I think the machines that are already infected might do something new on April 1.”

Let’s hope, for everyone’s sake, that it turns out to be an April Fools’ Day hoax.


TEST your system’s safety for free by attempting to go to f-secure.com. If you can’t, you can download the patch at microsoft.com to disinfect your PC.

Top 7 Biggest Internet Threats !

0 comments
The internet is filled with threats real and imagined, from malicious hackers to government censors.

Beyond the hacks and cracks — and in celebration of Sunshine Week — we've compiled a brief list of some of the biggest public and private threats facing the internet.

1. Warrantless Government Monitoring : Following the Sept. 11 terror attacks, the practice of wiretapping all internet traffic began in the United States with the Bush administration, and is now being defended in court by the Obama administration. All of the nation's major internet service providers are accused of funneling Americans' online traffic to the National Security Agency without warrants.

2. Private Censorship : From the mundane to the frightening, the examples run rampant. Wikipedia, the world's most trafficked online reference tool, is subject to shameful spin from trusted names of news organizations to the not so trustworthy engines of commerce. Among the examples, The Boston Globe enhanced the biography of a columnist while deleting information about his alleged plagiarism. Diebold excised an entire section critical of the company's voting machines.

3. Government Censorship : Reporters Without Borders reported last week that 12 nations — China, Burma, North Korea, Vietnam, Egypt, Iran, Syria, Saudi Arabia, Turkmenistan, Uzbekistan, Cuba and Tunisia restrict internet access and often prosecute users for what they post online.

Even in democratic countries, censorship rears its ugly head. On Thursday, a secret blacklist surfaced detailing 2,395 webpages the Australian government is planning to filter from the internet. While about half of them dealt with illegal pornography, the remainder did not. Some of the sites were about gambling, dentists and even dog kennels.

In December, Wikipedia couldn't be edited by users in Britain. The entire site was put on a blacklist because it linked to the 1976 album cover of Virgin Killer by the Scorpions, which featured a nude young girl.

In the United States, a federal judge last year blocked WikiLeaks from operating in the country for a week after the renegade site posted allegedly stolen documents detailing individuals' Swiss bank accounts.

4. Deep Packet Inspection : Several U.S. internet service providers, including giants like Comcast and Cox Communications, have started inspecting the contents of internet packets, a practice (.pdf) allowing them to monitor, filter and ultimately control the traffic that passes through their pipes. In addition, online advertising services like NebuAd are paying ISPs to let it eavesdrop on web users via DPI.

5. ISP Tiered Pricing : Major ISPs, including AT&T, Time Warner and Comcast have moved or are gravitating toward pricing services based on the amount of bandwidth individuals use. Theoretically, the plans could unlock the internet door to low-income users. But we suspect the plans are designed to increase profits for ISPs as bandwidth use skyrockets — all of which may have a chilling effect on internet usage.
6. Recording Industry Association of America Proposes "Three-Strikes" Policy : The record labels are pushing for ISPs to ban service to customers the RIAA claims are file-sharing copyrighted music. Overseas, industry groups like the International Federation of the Phonographic Industry are pursuing similar efforts.

7. Digital Millennium Copyright Act Abuses : Unwarranted YouTube takedown notices by misguided copyright holders comes immediately to mind — including assertions by Universal Music that it need not consider whether a video, under the DMCA, makes a "fair use" of the copyrighted works in question. Google says 57 percent of takedown notices it received were sent by business targeting competitors and 37 percent were not valid copyright claims.
