Social Networking Security Threats
With so many users, Facebook is a target for scams; it can also expose your personal information far beyond your group of friends.Users need to remember that Facebook makes money from its advertisers, not users. Since advertisers want to get their message out to as many people as possible, hvordan få mange likes på instagram Facebook shares your information to everyone, not just your "friends." And most recently, Facebook's facial recognition technology automatically suggests that friends tag you, unless you turn it off.Scams on Facebook include cross-site scripting, clickjacking, survey scams and identity theft. One of the scammers' favorite methods of attack of the moment is known as cross-site scripting or "Self-XSS." Facebook messages such as Why are you tagged in this video? and the Facebook Dislike button take you to a webpage that tries to trick you into cutting and pasting a malicious JavaScript code into your browser’s address bar. Self-XSS attacks can also run hidden, or obfuscated, JavaScript on your computer allowing for malware installation without your knowledge. Facebook scams also tap into interest in the news, holiday activities and other topical events to get you to innocently reveal your personal information. Facebook posts such as “create a Royal Wedding guest name” and "In honor of Mother’s Day" seem innocuous enough, until you realize that information such as your children’s names and birthdates, pet’s name and street name now reside permanently on the Internet.

This malicious technique tricks web users into revealing confidential information or takes control of their computer when they click on seemingly innocuous webpages. Clickjacking takes the form of embedded code or script that can execute without the user's knowledge.
SNSs Hit the Mainstream
From 2003 onward, many new SNSs were launched, prompting social software analyst Clay Shirky (2003) to coin the term YASNS: “Yet Another Social Networking Service.” Most took the form of profile-centric sites, trying to replicate the early success of Friendster como ter mais likes no instagram or target specific demographics. While socially-organized SNSs solicit broad audiences, professional sites such as LinkedIn, Visible Path, and Xing (formerly openBC) focus on business people. “Passion-centric” SNSs like Dogster (T. Rheingold, personal communication, August 2, 2007) help strangers connect based on shared interests. Care2 helps activists meet, Couchsurfing connects travelers to people with couches, and MyChurch joins Christian churches and their members. Furthermore, as the social media and user-generated content phenomena grew, websites focused on media sharing began implementing SNS features and becoming SNSs themselves. Examples include Flickr (photo sharing), Last.FM (music listening habits), and YouTube (video sharing).With the plethora of venture-backed startups launching in Silicon Valley, few people paid attention to SNSs that gained popularity elsewhere, even those built by major corporations. For example, Google’s Orkut failed to build a sustainable U.S. user base, but a “Brazilian invasion” (Fragoso, 2006) made Orkut the national SNS of Brazil. Microsoft’s Windows Live Spaces (a.k.a. MSN Spaces) also launched to lukewarm U.S. reception but became extremely popular elsewhere.Few analysts or journalists noticed when MySpace launched in Santa Monica, California, hundreds of miles from Silicon Valley. MySpace was begun in 2003 to compete with sites like Friendster, Xanga, and AsianAvenue, according to co-founder Tom Anderson (personal buy instagram followers and likescommunication, August 2, 2007); the founders wanted to attract estranged Friendster users (T. Anderson, personal communication, February 2, 2006). After rumors emerged that Friendster would adopt a fee-based system, users posted Friendster messages encouraging people to join alternate SNSs, including Tribe.
Expanding Niche Communities
The visibility of a profile varies by site and according to user discretion. By default, profiles on Friendster and Tribe.net are crawled by search engines, making them visible to anyone, regardless of whether or not the viewer has an account. Alternatively, LinkedIn buy instagram likes spread controls what a viewer may see based on whether she or he has a paid account. Sites like MySpace allow users to choose whether they want their profile to be public or “Friends only.” Facebook takes a different approach—by default, users who are part of the same “network” can view each other’s profiles, unless a profile owner has decided to deny permission to those in their network. Structural variations around visibility and access are one of the primary ways that SNSs differentiate themselves from each other. One disguise is a button that appears to perform another function. Clicking the button sends out the attack to your contacts through status updates, which propagates the scam. Scammers try to pique your curiosity with messages like "Baby Born Amazing effects" and "The World Funniest Condom Commercial – LOL". Both clickjacking scams take users to a webpage urging them to watch a video. By viewing the video, it’s posted that you “like” the link and it’s shared with your friends, spreading it virally across Facebook. Clickjacking is also often tied to “survey scams” which trick users into installing an application from a spammed link. Cybercriminals take advantage of news topics, such as the Osama bin Laden video scam, which takes you to a fake YouTube site in an effort pics for instagram likes to get you to complete a survey. Scammers earn commission for each person that completes it. Taking the survey also spreads the scam virally to your Facebook friends. In theory, new Facebook security features provide protection against scams and spam—but unfortunately they’re mainly ineffectual. Self-XSS, clickjacking and survey scams essentially did not exist just a few years ago, but they now appear on Facebook and other social networks on a daily basis.
