Travis Megale is happy with his job. User usual Facebook , he knows how to use the site properly and what not to say or publish. Unfortunately, many Facebook users do not think so - and layoffs caused by inappropriate behavior in social networks seem to gain more headlines.

A recent survey by security firm Proofpoint email revealed that 7% of organizations have fired an employee because of his activity on social media sites. Another 20% said that because of social networks, employees had to be warned. These are statistics like these that inspired Megale to create a Facebook group entitled "Fired because of Facebook" (fired because of Facebook).

Fictional Facebook unmasks security experts

"I am a hacker for over ten years," says the profile of Robin Sage, a beautiful girl, created just to show that social networks can be a danger.

Hundreds of professional segments of IT security, military and people connected to the digital intelligence were recently embarrassed by sharing private information to a fictional character named "Robin Sage." She had profiles on social networks relevant, appeared as an expert in digital security body of the U.S. Marines and was created for the sole purpose of exposing the risks of involvement with social networks.

In an interview with Computerworld, the "father" of Robin, co-founder of Provide Security, Thomas Ryan, said he used some pictures to give a face and appearance of a normal person in Facebook , in LikedIn and Twitter . Thus, Robin, fond of computer and training at MIT (Massachusetts Institute of Technology), a character almost became real. Then she made connections with over 300 contacts between men and women, all from the army, intelligence agencies, and information security companies and companies with contracts with the U.S. government.

According to Ryan, the objective of this action was to determine the efficiency of social networks in the implementation of actions aimed to capture sensitive data.


People believe what they want to believe

Even with many warning signs - such as the absence of a professional resume in the last ten years in the life of 25 year-old - the scheme worked. Contacts Robin, represented graphically with the image of Scuito Abby (NCIS character in the series), began to emerge in less than a month. Several friends parted photos and personal information, some came to invite her to conferences and even asked to revise some documents. Other "friends" of large companies like Lockheed Martin and Google, came to entertain potential hires.

If it were seriously

If Robin was a spy, an external agent, she would have access to a large amount of useful information, says Ryan. Next week, Ryan will present the results of the experiment during the BlackHat Security Conference in Las Vegas. Here are excerpts from an interview with Computerworld:

Computerworld: What motivated you to do this experiment?

Thomas Ryan: The strongest motive was all this talk about war and espionage digital, the consistencies and inconsistencies on these issues. I was interested to see how much you can extract information from people via social networks. Also wanted to know who the people are more likely to click on something that does not know right. I was interested to know how fast such a phenomenon is spreading. I find that using the names of MIT and preparatory schools I attended was a good way. If people do not remember you, do not click. So, it is more difficult to enter these circles than in groups and information security.

CW: And how many connections Robin could do?

TR: On Facebook, 226; in LinkedIn , 206; Twitter followers, Robin got 204. Facebook connections were predominantly military and security officers; on LinkedIn, the contacts were agents of security and intelligence. Robin's followers on Twitter were mostly hackers.

CW: And where did the approach? Robin went after people or let them come to her?

TR: It was a bit of both. At first, I approached some people. most security staff. It is they who have the most contacts. These people are usually very open and very sociable.

CW: What kind of information could be obtained via these connections?

TR: Of all kinds. Since email addresses to bank data. I saw the patterns of friendships that exist. The profiles on LinkedIn, for example, have more recent business contacts.

CW: Why do you believe that Robin was so successful?

TR: Because it is beautiful. This helps a lot.

CW: And most of the contacts were men?

TR: Yes The ratio was 82% men and 18% women. Among women, the majority came from the security industry, made promotions of events and conferences.

CW: Do you believe that a male figure could do so successfully on the network?

TR: It depends on how it is presented.

CW: What was the action taken by Facebook to see that his character was not real?

TR: They deletaram my personal page and the Robin. They said that due to "security issues", I would not be allowed to use Facebook. LinkedIn deleted my page, but a copy still exists in the Google cache.

CW: What is the great discovery of the project?

TR: Is that one should not add someone unknown. The same tactic was used to infiltrate a secret base in Israel. Those were the only base on a particular page on Facebook. There were those who had succeeded in joining the group and receive sensitive information.

CW: Any other comment?

TR: I could never establish any relationship with people in the CIA or FBI. I tried that as well. When the experiment was coming to an end, I noticed an incredible increase of people in the Middle East by visiting the homepage of Robin, the search for government information and systems. Not that I have been scared, but it is hard to ignore such a thing.

Justice France sentenced late on Thursday (24) to five months probation the young Frenchman accused of invading the accounts of U.S. president, Barack Obama, and Britney Spears in 2009.

Francois Cousteix, 23, was relieved with the sentence and will not appeal the decision of the Court of Clemont-Ferrand.

The sentence, however, is harder than requested by the Tax Ministry, which had asked for only two months of the sentence for a crime that could have cost up to two years imprisonment to the hacker. Cousteix also invaded the care of Evan Williams, creator of Twitter .

The young man, who has a degree in electronics training, defended himself before the Court alleging that he had not destroyed anything and that his offense was a "preventive action to alert Internet users" on their choice of passwords.

On some occasions, there is no need to hack the account on the social network, just pretend you forgot the password and answer a security question, which can be as obvious as the city of birth of the holder or the name of your pet.

Cousteix was arrested on March 24 this year by French and American police officers specializing in Internet crimes.

Issues such as the World Cup and conflict in the Gaza Strip baits are to install spyware and trojans on your computer of the internet.

Trend Micro has identified a potentially dangerous threat that uses Javascript code to affect users of Twitter . It is the first time that such a strategy is used specifically against members of the microblog.

According to digital security company, the attack is basically an adaptation of the present in phishing messages, an alternative very popular with cybercriminals in recent years. According to Rik Ferguson of Trend research team, both PDF documents and executable files are being used as bait to trick internet users.

"The spy program, to be installed on the machine, like downloading other malware. We are investigating, "he said.

To entice users to click on the link infected, hackers take advantage of the issues that are highlighted on the world stage. In June, for example, the problems in Gaza and the World Cup were elected.

The caution that social network users should have no different posture recommended for other environments of the Internet: "It is best to not click on links sent by unknown people, you never know what the destination address. This is not the first threat on Twitter and certainly not the last, "Ferguson concluded.

This is one kind of cyber threats that should be more used by cyber criminals, Symantec said.

The trends for 2010 in relation to cyber threats are the increase in the number of occurrences with deceptive software, infection of URL shortening services - widely used feature in Twitter to compress web addresses - spam for instant communication services in various languages, including Portuguese.

The digital dangers also involve what experts call a specialized malware, which can be understood as the use of malicious code for specific services, such as smartphones and box electronics .

This is the summary of the scenario that the security company Symantec projected for next year.

Many of the threats are already known. What draws attention is the sophistication of the company and the prospect of increased numbers of certain occurrences.

"The use of masked URLs will grow, because it involves a great use for people. The intention is to trick the user to make you think that will access a particular site, when in fact it will be directed to an infected site, "says the director of engineering at Symantec, Paul Vendramini.

"Another method that deserves attention is the use of deceptive software. In this case, the criminals sell programs that are supposedly safe, but the real goal is to steal passwords and other user data, "he says.

"It should be noted that there is an expertise in the profile of threats. Thus, malware for smartphones are also common gora show. "

What you need to know about safety on social networks

Do you feel safe while browsing social media sites? If you answered no, know you're not alone.

You or someone within your company participates in social networks and access through the infrastructure of information technology work? Do you feel safe with this kind of access? If you said no, know it is not sozinho.De according to research from security firm Sophos, released in early May, 63% of corporations in the world are afraid that communities bring Web 2.0 security risks to corporate infrastructure .

Nevertheless, most companies allow full access to collaborative tools. , 49% do The analysis shows that 43% of them give the possibility to use Facebook , 50% of Twitter , 49% of . MySpace and 52% of LinkedIn .

For the vice president for Latin America and the Caribbean security firm Kaspersky, Alejandro Stetson, users rely too heavily on content viewing these networks and do not take basic precautions. "Even in specific communities such as LinkedIn, attention must be paid. The information technology professionals have every reason to worry about access to this type of site, "he says.

Links

Threats can come from various sources, ranging from general attacks, with links to malicious code, by actions more targeted and focused on achieving certain companies. It is important to bear in mind that criminals are increasingly sophisticated and specialized in deceiving employees with messages seemingly harmless and even through social engineering .

Another example of the evils that networks can bring is Twitter . The tool has gone through a situation that exposed your entire risk. A hacker exploited a vulnerability in the tool to run an application in Java Script infecting the profile and computer accessed by the poster. "With this, the user was exposed to hijack the browser and can receive malicious files and, therefore, put the corporate environment at great risk," says Gabriel Menegatti, chief technology officer at security company F-Secure.

Thus, the technology department can have two attitudes: to block access to the tools or use means of protecting the company's infrastructure with actions of awareness and constant monitoring of the network. In environments where social networks are important for work, the lock is not an option. It remains to stick to the best practices of corporate security and implement a culture among users.

Management

To Roger Denny, a security expert in the area of the company Safenet, we can not do without a good management of antivirus , firewall and other solutions to prevent entry of malware in the enterprise. "What should be done more consistently and that few companies do is a daily process analysis of vulnerabilities and risks and how these elements can affect the infrastructure of the corporation, "he says.

Spreading the culture of safety is something a little more complex, since it does not depend on technical and educational rather constant. According to Mark Prado, channel manager for Websense, the best way to start is not necessarily talking about technical risks, but spreading the surest ways to convey information. "The approach to security companies should be less focused on details of infrastructure and more focused on proper handling of information," he attests.

Blog Status Twitter says it is defending against denial of service. Site is down since Thursday morning (6/8).

The microblogging service Twitter faces serious problems on Thursday (6/8). At 10 or so, the service fell and remained so until noon. Since then, alternating moments of operation with further falls.

In the blog that shows the status of the service , Twitter says only that "is defending a denial of service".

Around noon (GMT), an update was published saying that the site had returned, but the team still Twitter on high alert against further attacks.

A denial of service, or Denial of Service (DoS), sends a large volume of traffic to a website which then becomes overloaded. While some users are still able to access it, most can not see anything but a message that the response time has exceeded the limit.

The last interruption Twitter had occurred on June 16, when the site was down for an hour for scheduled maintenance.

Twitter has become a sort of digital Procon. Whenever a service goes down - business, government, or the Internet itself, it becomes a forum for complaint in real time by the Internet.

When this happens, users often use the hashtag # fail (failure in English), as a way to facilitate the search for others who are facing the same problem.

The Twitter gem about 44 million users worldwide, more than in the population of countries such as Argentina (41 million) and almost equal to that of Colombia (45 million).

Learn the 5 most popular scams on Facebook and Twitter

Social networks become more popular, and with them grows the number of scams and frauds online. Meet five threats you should avoid.

Nearly three in ten social network users have experienced some form of online threat as virus infection or attempted coup, according to a recent survey by security firm Webroot.

> 63% of companies fear data theft

With increasing popularity of social networks , they become more attractive to criminals who seek to profit from fraud on the web.

We selected five of the most popular scams recently detected by security analysts on services like Facebook and Twitter . Check out:

1. Secret details about the death of Michael Jackson
Celebrity news will always be used by criminals because they know that people love to gossip. The most notable recent episode of the kind, the death of pop idol Michael Jackson, has been the subject of thousands of malicious emails containing viruses in attachments, according to security companies like Sophos.

Typically, malicious messages on Twitter and Facebook related news of celebrities with links that supposedly have "secret information". In the Jackson case, some scams also promise new songs of the star and encourage users to do downloads.

Another common practice of the attacks is to offer a software update Adobe Flash to play the video. Instead of updating, the file installs a Trojan-horse or other malicious program on your computer of the victim.

"Perhaps the most famous virus is the twitter -accounts-suspended-user-of-the-affected-virus Koobface "> Koobface," said Sophos senior consultant Graham Cluley. "There has been more alternatives in order to steal data from your computer. Once compromised, your PC can be used to send unwanted email (spam), installation of spyware (spyware), identity theft or activation of denial of service, "he said.

2. I'm in a trap in Paris! Please send money
This fraud has been reported several months ago, but still surrounding the Facebook : A friend sends, by instant messaging social network, a message that fell into a trap in some foreign country and was robbed or lose your wallet in an accident. He needs money to get home quickly.

The person on the other hand, is actually a virtual criminal who broke into his friend's account.

"We usually get emails saying 'just provide your bank details we will make the deposit.' The criminals behind this scam have won millions, "said Cluley. The analyst says that many scams use the name of the spouse or child of the victim to make the email look more legitimate.

3. My God! You've seen these photos?
Both Facebook and Twitter - and also for users of Orkut - fraud involving the above question is very common. Attracting attention for a photo in which you supposedly appears, he is taken to a fake login screen and password. This mimics the Facebook page but, in fact, steal the data entered.

Variations of the coup also use phrases like "It's true what they said about you on this blog?", Which leads to a fake Twitter page that also steals login and password.

The tip is: if your browser point to another address that does not begin on facebook.com or twitter.com, exit the site immediately.

4. Test your IQ
Facebook members who have recently decided to use an application that offered tests of intelligence quotient (IQ) were negatively surprised when they realize they have signed, unwittingly, a service that costs $ 30 a month.

The IQ Test looks like any other little game of questions (quiz) Facebook. However, once completed, it asks the user to enter the number of the cell to receive the results. Thus the user is registered with a text messaging service. Many victims say that the terms of service are in letters so small that it is almost impossible to perceive them.

This is just one of many examples of Facebook applications being used to spread viruses in the computers of users.

Communities false
In the United States, a community of Facebook was said to be the area of ​​recruitment of Butler University in Indiana, aimed at secondary students wishing to enter into the institution in 2013. The community actually belonged to university and could have been used to steal data from students.

The best way to avoid the danger of entering communities would be false to ignore invitations to communities sent by users who do not know, say experts. In addition to capturing data, it is common for these bogus groups users to initiate chats with members who install malicious software on a victim's PC.

Hello people,

For some time I'm watching the growth of companies that make the shortening urls to meet the deficiencies microblogs like Twitter that do not support full urls because of its limitation of characters in the text field. But so far none of the companies analyzed showed enough concern in the verification of urls in order to compare with a black list of malicious sites or something.

In my opinion one of the biggest mistakes of security is to use microblogs such feature, even more for being of others.

What they could do is create a system to analyze the urls and automatically remove those that are considered dangerous to take the user to malicious sites and also transform the shortening urls on the actual urls.

What is your opinion?
