Twitter has many of the same malware, phishing, hijacking and social engineering issues that Facebook has, and the solutions for those problems would be the same. Because users don't provide much personal information to Twitter, and can even create accounts using all fake information, and because anyone can follow anyone else, there aren't the same issues with privacy, either. But that makes life easy for spammers. 


Security does seem to be a worrisome thing with Twitter. The site has had several serious problems from employee accounts getting compromised. In January, someone hacked into the Twitter internal network -- possibly by guessing the password -- and gained access to the Twitter accounts of President Obama, CNN anchor Rick Sanchez, and 31 other high-profile Twitterers. In May, someone broke into Twitter's network and gained access to 10 accounts, which appeared to include Britney Spears and Ashton Kutcher. In that breach, a hacker was able to gain access to a Twitter employee's Yahoo account through the password recovery system and from there get information from other sites, including access to the employee's Twitter account. And last week, the legitimate account of a Twitter employee was used to hijack the site and redirect visitors to an external page displaying a banner for the "Iranian Cyber Army."


Meanwhile, Twitter was crippled (and Facebook and other sites also affected) by a rare politically motivated denial-of-service attack targeting one user in August. However, that incident reflects more on Twitter's ability to keep the site up in the face of an attack and accessibility than it does about security risks to users. 


Twitter users are susceptible to getting their accounts hijacked, and the site has been targeted by clickjacking pranks. In these social engineering attacks, users were encouraged to click on links that distributed the original tweet to all of the Twitter user's followers.


Users with large numbers of followers have an added responsibility to be careful, particularly when setting accounts to automatically post items from news feeds. A malicious post on an unmoderated news feed that venture capitalist Guy Kawasaki was re-tweeting distributed a Trojan to more than 139,000 followers in June. 


Kaspersky offers a Krab Krawler tool that analyzes tweets as they get posted on Twitter and blocks any malware associated with them. Trend Micro has technology that monitors Twitter posts for malicious URLs, as well as looks for attack patterns in the posts, such as use of popular terms to indirectly lead people to malicious links. And Finjan offers a free browser plug-in dubbed SecureTweets that warns users when they encounter a malicious URL in Twitter, as well as Blogger, Gmail, Google and a host of other popular sites. To keep up with security issues on Twitter follow Twitter's Spam Watch account. 


Social networks are also susceptible to other serious security problems that can hit any type of Web site. For instance, last week passwords of 32 million stored in plain text on the RockYou site were exposed by a SQL injection attack, according to security firm Imperva. Because the passwords are used on other affiliate sites to the social networking application maker, the breach jeopardized other accounts, like Gmail, Hotmail, and Yahoo. 


So what do you think?? Is it still safe to use social media networks??
